1. Lecture 1a Product Association (Disection)

2. Where is product association in design process Both in background research and concept generation Background research: understanding customer needs, understanding working principles, Concept generation: understanding function analysis (force flow) for function decomposition. Lecture 12

3. Product Association Identification of needs: have learnt in previous section by walk through with the product Understanding the functions and the decomposition of the functions Understanding the working principles Lecture 13

4. What is product association Product association is to study the related product in order to understand the working principle and give us more area to be explored for research background.

5. Single product association To go detail on the specific information Purpose: how it works?, Working principle of the machine, Functional Aspect Trigger mechanism Holding Stability aspect Example: working principle

6. Multiple product association Common: all the gadgets have trigger Stability is considered in every design Not common: Method of storing the energy: stretching the launching rubber, stretching the gadget Different form of rubber band: rubber band and rubber ball Objective: to understand what is the must function in the system and what is the extra function.

7. Product Association: Analogical Study Do not choose only related product and other unrelated product can be used as analogical study

8. Function Analysis (Force Flow) Function is the logical flow of energy, material, and information between objects or change of state of an object caused by one or more of the flows. Some parts may have more than one functions, i.e. bicycle handle is used to steer, to exert the force during cycling and to stabilize the bicycle. Some functions may handled by many parts, i.e. force exertion: pedal, handle, tyre Lecture 18

10. What do we get from production association? Understanding the working principles The diagram for force flow of the system and sub-systems. Understanding for function and behavior for concept development. Lecture 110
