Professional development/Design thinking/Detailed designs
A detailed design is something that should be created in between a concept drawing and the start of prototyping. The purpose is to have a concrete plan of what the prototype will look like and what components might be needed. This is not to say that it cannot change as progress continues in the project, it should be updated as you learn from testing various prototypes. The goal is also to start quantifying different parts of the project and thinking about how each part will be built or where it will come from. A good design does not need to be made from scratch, you do not want to reinvent the wheel so use existing pieces where they exist.
A detailed design will not look the same depending on the type of project you are working on, below are some examples.
Mechanical
For a mechanical project a concept drawing might be a rough hand sketch to get general ideas across but it typically does not have much detail. A detailed design should include:
- All individual parts in the design with thought into how exactly they will be manufactured (laser cut, 3D print, machined, etc) in which material (plastic, wood, metal) or what items will be bought.
- Assembly of all parts and thought into how exactly they will be put together (permanent, temporary, etc) and how (fasteners, adhesives, etc).
- General dimensions are also important to be able to think about how much material needs to be bought and if items are readily available in that size.
A detailed design can also be a hand sketch, like the concept drawing, but it can also be a CAD representation.
