For All Sec 1: Revision Notes 2 (Structure - Types of forces)
Hi All,
You need to know the different type of forces acting on the member of a structure.
In summary,
1. A compression / compressive force will cause a member of structure to be squashed. The member that is in compression is called a strut.
2. A tension / tensile force cause a member of structure to be stretched. The member that is in tension is called a tie.
3. A torsion / torsional force cause a member to be twisted.
4. A shear force cause a member to slide/tilt to a side.
More notes on static and dynamic loads and examples of types of forces

I thought it was a fabulous piece of contextual drawing...
Link: http://www.ideagrowing.com/ideagrowing-1.php
For S4 - What to include in contextual usage?
HI,
Basically Contextual usage is an opportunity to tell other of the features and functionalities of your product, preferably in pictorial form.
It must include, IN PICTORIAL FORM with some supporting statements
1. concise explanation on the essential functions (how it works, illustration of technology like circuit wiring, mechanism usage, application and ASSEMBLY)
2. explanantion of essential features. For e.g. illustration of height adjustment capability, illustration of collapsible capability, illustration of different usage/outcome in day and at night, illustration of different colour theme for specific purposes, illustration of different switches used for different applications, etc
collapsible means can make it more compact.
Regards

For Sec 4E: How to do Contextual Drawing???
Hi Sec 4,
You are at the final phase of the coursework. 1 more week to go before the deadline..
As for contextual drawing, many are still unsure of how it is supposed to be done.
Method 1:
Find the right context picture from internet to fit your 3D drawing that you have drawn earlier. Make sure that the angle and orientation of your 3D drawing is right. Else, you have to draw the 3D product over the context.
Method 2:
You may take a photo of an appropriate context in the angle you would place your product (i.e. 3D drawing). Then, paste or draw the 3D of your product onto the context.
Method 3:
Use Sketchpro software to create your contextual drawing. This is the most professional among all. First, you find the right context and overlay the 3D drawing over.
Below is a video showing how contextual drawing is done.

For my Sec 1: Example of Product Research on Mobile phones
Hi,
How a designer carried out product research on similar products is very crucial to making his/her new or improved product a success.
As a designer, you need to have an eye for details that pick up the strengths and weaknesses of a product. From there, you can work on the weaknesses and come up with an improved and better version.
Based on the four design considerations you learned earlier, we will use it for the product research looking into the strength and weakness of 1 mobile phone.
Functions: It is solar powered, waterproof cellphone, which means it can use sunlight for charging. It has a clock display function which makes it very convenient for busy people who have many appointments to meet.Aesthetics: It is a flip phone with simple and slender design that comes in types of colour. The colours are not vibrant perhaps it is intended to convey the meaning of saving the environment. The solar panel at the centre adds to some dashes of contrast and uniqueness in the design.
Ergonomics: The design is slim such that it can fit into the palm size of user comfortably. It is also thin so that it can put in the pockets easily without creating unsightly protrude in the pants.
Materials: It is made of strong, durable plastic for the exterior so that it can withstand the handling of user and sometimes, absord the impact of a fall.
Conclusion: This type of phone may be suitable for young sportsmen/women who are constantly on the field or executive who are constantly out of office due to its solar powered capability. They do not have to worry about running out of battery.
Do the same evaluation for the 2 mobile phones below in terms of its functions, aesthetics, ergonomics and materials and lastly, make a conclusion on the intended user the design is catering for.
For Sec 1: Topic On Design COnsiderations & Assignment (12 Jul - 16Jul)
Hi my Sec 1 groups,
As a consumer when you want to buy a product, you would consider these following factors on several similar products before you make a decision on which to buy.
Like wise as a designer, we need to consider these factors so that we can better cater to the needs of our potential customers.
These design considerations are:
(1) Function - How the products work? What are the functional features in the product?
(2) Aesthetic/Appearance - How the product looks? What are the designs?
(3) Ergonomics - Is the product easy to use? Is the product comfortable to use? Is the prouct safe to use?
(4) Materials
Assignment (12 Jul - 16 Jul):
You need to find at least 3 pictures, drawings or photos of fun and interesting namecard holders.
You will do a product research on these 3 pictures, comment and compare them based on the 4 design consierations above.

Production planning
Development Update
Hi,
These are the breakdown of what you might consider under the development in your journal.
The mindmap below outlines some of the factors affecting the development of a design.
Factors to consider in development.
Ergonomics: Design for human usage. For eg. Any parts of the design which has handle / Design that fits into palm size / Design to be wore over the wrist or any bodyparts / Design to be hung on wall. You will have to look into ergonomics. Refer to my previous post on ergonomics or click here for more.
Shapes and Forms: REMEMBER, THE DESIGN FROM IDEATION YOU HAVE CHOSEN IS NOT THE FINAL DESIGN. Parts of the design you can still modify forms further to make it aestetically appealing and ergonomically comfortable and safe.. Click here for reference.
Materials: Have to research and find the right material that will influence the final design. For example: For wearing accessories, what material would be suitable so that it is light? / For the base of CD holder, material that is durable and strong? Click here to find out more and here1 and here2 for more samples.
Function (TECHNOLOGY): What function does your product has? For eg: A product that turns for a few second when activated has to research into and consider on the mechanism (gears) and electronics (motor, timer circuit and its wiring) / A product that produces light may look into different light outputs and circuit design and implementation. Refer here or here for more. For samples of development of mechanism, click here.
Construction/Assembly: You need to plan and detail down how you cut and join each eseential parts in your joournal. It must tie in with your production plan. Prior, Research on the joints and fixings suitable for your design. Click here for more info on joints and fixings. Along the making, do take a snap shot of essential stages and detail down any changes, modifications , challenges in your development in the journal.

How to Develop? Part 2
Hey,
In your development, you can work to improve the shapes and forms of essential parts of your product like handle, grip, height, length, etc to improve on its ergonomics aspect.
Do a model on just the essential part like the grip or handle to have a feel of its comfort and ease when holding before finalising the sizing. Try out the model. THIS IS IMPORTANT.

How To Develop? Part 1
Pls refer to the blog post on WHAT to develop first.
http://dnt-thoughts.blogspot.com/2010/03/development-what-you-should-be-doing.html
I won't be going through every parts detailed detailed in the earlier post on 'what you should be doing for development'.
Put it simply, u develop starts from the final idea and it usually starts with
(1) improving, modifying shapes and forms to make it more ergonomic, aesthetics and functional. (MUS TIE IN WITH DESIGN SPECS). Usually, we consider the different parts of the final design to improve rather than the whole design.
(2) research into the right types of material, evaluate and make a decision on the material you want to use WITH JUSTIFICATION. Again, tie in with DESIGN SPECS.
(3) Research, evaluate and make decisions on technologies for your design to make it more functional and purposeful.
Below is a sample of research into various switches for the input process.
Another sample of technology segment touches on the choice of mechanisms for a toy project.
To know more in detail click on the link. http://www.technologystudent.com/despro2/mech1.htm
(4) Work on the dimension and sizing of your project.
For instance, take human body measurement to decide on the height of a walking toy, the length of the handle and size of the handle grip. See the Pics Below.
You may use maths concept to work out the dimension required. Make a model or mock up to gauge the sizing
You can use similar product research and comparision to roughly guage the size, technology, materials and colour for your idea. For more click here: Similar product comparison: http://www.technologystudent.com/despro2/prod_cp1.html
Make a model to help in making sure your design is going to work or need more modification. It also helps in deciding on the actual sizing. For more click here. Making of model for evaluation: http://www.technologystudent.com/designpro/model1.htm and http://www.technologystudent.com/despro_flsh/modmak1.html.
Ask potential user to feedback and evaluate on your model for improvement or refinement.

For instance, take human body measurement to decide on the height of a walking toy, the length of the handle and size of the handle grip. See the Pics Below.
You may use maths concept to work out the dimension required. Make a model or mock up to gauge the sizing
You can use similar product research and comparision to roughly guage the size, technology, materials and colour for your idea. For more click here: Similar product comparison: http://www.technologystudent.com/despro2/prod_cp1.html
Make a model to help in making sure your design is going to work or need more modification. It also helps in deciding on the actual sizing. For more click here. Making of model for evaluation: http://www.technologystudent.com/designpro/model1.htm and http://www.technologystudent.com/despro_flsh/modmak1.html.
Ask potential user to feedback and evaluate on your model for improvement or refinement.

MY THOUGHTS
Hi,
Generally, most of you have started making and you are progessing fine but definitely still more rooms for improvement.
A few still take your time on your journal which is supposed to be done at home. I am disappointed and you are wasting your time away in the workshop. Things in the journal should be done at home. While in the workshop, your focus is in the making.
Development and making should go hand in hand. While you are developing at home, you come to school to verify your development with me and realise your project on what you have developed.
Along the making you make mistakes or need further modifications, detail it in the journal. This is a real-time account of your developmental and making process.
Time is not on our side. Making can only be done in workshop. You cannot bring it back home and do. I want to clear your making asap so that I will have more time to vet through your journal while you are away for mid year exams. I also want to cater time for presentation board.
If you keep harping on working your journal in the workshop, you are going to drag everyone's progress down. In the past, we have two teachers. Allocation of manpower to help student is easier. Now, I am the only one handling your group, I will have to make sure that time is fully optimised. I seek your cooperation in that.

Development -What You Should be Doing?
Hi, Not sure how to do.... Read below. ASK ME IF NOT SURE...
You should have at least 5 detailed ideas which is thoroughly explored.
For the finalised idea you have chosen, develop on it.
Development.
(1) Improvement on the forms and shapes.
1. Take into account of ergonomics, you may want to modify the shapes
and forms of your final design to make it safer and easy to use
2. Taking into aesthetics/appearance, modify the shapes and forms to make
it more interesting and appealing to your target user.
3. Taking into its functionality and implementability, modify the forms and
shapes to make it more functional.
(2) Types of suitable materials for your design
1.Research on different materials to meet the context and requirement.
2. Evaluate and decide on the material
(3) Dimension and sizing of essential part.
1. Use human measurement (anthorpometry) such as shoe size, human height,
length of arm to determine the essential length/ height of your product
2. If need, use maths (for. eg, trigo) to calculate its dimension
3. Make a model or mock up
(4) Technology
1. Research on different types of technolgy that makes your project function
as intended. Explore various technology means. Do not constraint yourself.
For example:
(a) Mechanism - Research into various mechanisms that opens and closes
the valve to allow dispensing.
(b) Electronics - Research into various electronic component that emits
lights with good illumination. Research into electronic circuit that performs
a particular function such as lights up when darkness falls.
(c) Structure - Research on different means to stabilise your project or
reinforcement needed to increase its strength.
2. Based on the research, evaluate the different technology you researched
and choose a one suitable for your design with explanation and justification
(5) Assembly of parts and technology
(a) Detail down how you would like to make each essential part. Consider different approach. COnsider what machines you can use for making of parts.
(b) Detail how you want to make the technology part such as how and where you want to attach the gears or cams.
(c) Detail how you want to join parts together considering the types of joint
and screw avaliable.
(d) Along the way you are making, you may want to take photos of your making
process.
You should have at least 5 detailed ideas which is thoroughly explored.
For the finalised idea you have chosen, develop on it.

Ideation Process of Wrist Navigator For NS
Ideation process can be daunting especially if you don't know where to start..
There are many ways to kick start...
#1... refer to your exisiting product research, borrow their forms/shapes.
#2... from your target user analysis, knowing their likes/preferences and work towards the design.
#3... some designs that target user can relate to as in the case of my design of a wrist navigator design.
Since the target is soldier, we can adopt and modify on the designs/forms which they can relate to..

You should have completed ….
(1) Planning and Monitoring time line for main tasks and sub tasks.
(2) Problem Analysis with ample research done.
(3) Design Brief and at least 6 good specific/relevant Design Specifications
(4) A finalized idea.
In your journal, You should be continuing/starting to…..(Do AT HOME)

(4) A finalized idea.
In your journal, You should be continuing/starting to…..(Do AT HOME)
(1) Explore more ideas and forms for your design especially for your FINAL DESIGN. (REMEMBER always to tie in to your design specs.)
HOW TO EXPLORE???
(a) By researching into the forms/shapes that appeal to your target user.
(b) Through existing/similar product analysis and hence borrowing the existing form and shapes, adopting some ideation techniques (SCAMPER, Shape Borrowing, Relay thinking) to develop your truly own design.
(2) [A MUST HAVE] Create a mock-up or model from your finalized idea (THIS IS NECESSARY AND IMPORTANT!!!). Your mock up serves as a communication tool with your teacher and instructors.
(3) Research into relevant technologies for your development.
(a) Types of mechanisms suitable for your technology (For Eg: You may want to research on the types of dispensing mechanism if you are doing some dispenser unit OR explore into different types of mechanism that provides rotary motion if you want parts of your product to rotate OR you have some movement in mind, research into the types of mechanisms that produce these motion [Eg. A rack and pinion produces a linear motion].)
(b) Structures. [Research on how to make your product a stable unit that can stand vertically on the ground? Or What reinforcement to make a frame rigid and not collapse easily? Or the types of joint suitable for product? Or considering the angle inclination of the product in order to make it stable?]
(c) Electronics [For eg. Finding a light beam that facilitates in selection of routes, research into which types of LED or bulbs produces high intensity of light? Or research into which components/circuit can be used in an alarm? Or which types of motor guarantees a high turning speed?]
(4) Development.
(a) Decide and Take down Dimension for your product. It is good to do a mock up considering also the things you want to house in your unit. (For E.g. If you want to house a series of gears, record down the different gears sizes and measurement, that will help to decide your product height OR research into different sizes and length of shoes to help you decide your shoe holder OR research into the sizes of a CD to help you decide how the dimension of opening slot? OR research into the height of a table to help decide in the vertical standing height of your menu holder).
(b) Choice of Materials. [Decide on what material is important…. [Refer back to design spec, if you want to be waterproof, what type of material.. If you are going for light and portability, what types? Going for durability, what types? Again research]
(c) Detail down for e.g. how you are going cut certain materials? For e.g. How to make a slot on that material and the best method you can think of using? How to join certain parts together easily considering several ways? How to assemble the mechanisms to a unit without compromising its forms or other parts?
Making of artifact (ONLY IN WORKSHOP)
You can start your making once you have your finalized idea approved.
You can do your development together with your making.
You can start making a part first (for example, the base or the most essentially part of your artifact). You need to discuss with the teacher and instructor.. You need to draw a 3D sketch of your product or part you are making in your material list with all materials and dimensions listed. IF YOU HAVE A MOCK UP OR MODEL, IT WILL BE MUCH EASIER TO DISCUSS WITH INSTRUCTORS OR TEACHERS.
RECORD DOWN YOUR MAKING PROCESS IN THE JOURNAL. You may take photos of your MAKING stages.
WHAT IF YOU NEED TO MODIFY YOUR DESIGN? Yes, you may if you think it is necessary to add certain parts or modify certain parts or you research on certain shapes that might be a better form for your design… REMEMBER to account in your journal.
I do not want A RE_DO of everything as you should have planned and considered carefully for your design by then..
By 21st March 2010, I would be expecting 75% of your journal done (Problem situation, ideation, development and some evidence of your making process).
To complete at least 15% of your artifact making.
by then..ully for your design. es that might be a better form for your design.RS OR TEACHERS.
