Week 3

This Blog: Ideation, Screening and Selection 


As our pyrolysis idea was not feasible to be done in school, thus we have decided to change our idea.


New Idea: Self-Cooker


Research Gap - Heating Element

 

Heating Element (Constant Heating)

Substitution

Use induction heating instead of using a material to be the heating element

Combine

Warm + Heating (Cooking)

Adapt

Change shape of base and heating element

Modify

Rounded base

Double Stirrer

Ingredient Compartment

An opening on the lid

Put to another use

-

Eliminate

-

Reverse

-


To further improve on the product, we have decided to add an opening on the lid. This enables us to add spices or anything ingredients while the self-cooker in cooking.

Top 3 ideas based on feasibility:
1) Add more coils to the side to make heating more uniform

2) Double Stirrer

3) Adding a spice compartment

285


With spice compartment having the highest score of 285, it is our chosen idea.

The weightage for usefulness is given the highest of 30% because the design to be added on to our self-cooker has to be useful.

The next  highest weightage of 25% is given to money. This money includes the cost to buy all required materials and the transportation fee. A large expense can exceed our budget of SGD$2000.

Thirdly, the weightage of 15% is applied to machinability and ease of maintenance. Machinability is how easy we can build the product with the new idea. Easier machinability can help to simplify the building process. Ease of maintenance refers to how easy it is to maintain or repair when defects are found. 

Fourthly, the weightage of 10% is given to the Availability of Parts. We want our product to have the required materials obtained easily. Some materials which are uncommon can waste a lot of time to find.

Lastly, the weightage of 5% is given to appearance. Although appearance is an important aspect, the other criteria are more important. Appearance does not affect how the machine works which is the most important. However, we added appearance as some customers prefers appliances with nicer appearance.

In conclusion, our idea of adding a spice compartment is the best suited among all the criteria listed. It does not require many materials, and the required materials are common, cheap and easy to purchase. It is useful as other self cook machine may not have the function to add ingredients when it is cooking. With this idea, when the self cook machine has started. we still can add on ingredients which are needed to be added during the process of cooking such as herbs etc. Moreover, if we forget to add any ingredient, we can put into the spice compartment. This will prevent the opening of cooking lid, and preventing hot steam from escaping which can slow down the process of cooking.

Week 5

Design for Materials (DFM) Design for materials is the opposite of MFD. Instead of choosing the best material for the product, DFM is changing a design so that a particular material can be used. DFM can be used when the material used is expensive and we want to make sure we do not waste it. We can then use DFM to create a design which can make full use of the material, so that we will not waste any of it. Another example when DFM is used is when the material is not commonly used. We can then used DFM to make a product using the material. We can then cut down the used of commonly use materials with another material which is not commonly used. For our assignment, we had come up with a material and use it to enhance the functionality of an existing product through some changed in the design. We had chose the material "Alcantara" which is mostly used for making car seats' cover. We had thought to use Alcantara to make phone covers, or any product which requires a good grip. T...

Computer-Aided Drafting and Design (CADD) CADD is the use of software to draw and design physical components or to layout processes. With CADD, shapes and lines can be drawn easily and quickly, content can be easily copied, edited, saved and shared. CADD software also allows accurate calculation of dimensions and more advanced software can even accurately estimate the kinds and amount of materials used of the length of manufacturing time, which facilitates budget planning. It is hence beneficial for a product design to know how to use a CADD software. We had learnt to use Fusion360 to model shapes or designs. We can also use a 3D Printer to print our design we had made in Fusion360. In class, we had learn how to make a simple keyring and learn how to hasten drawing process through the use of sketch constraints.  Some of the common tools meaning used are: Offset  - Copy selected sketch geometry a specified distance away from the original geometry. Extrude - To make a 2 Dimensi...
