The starting idea
We want to design a toolbox that can become a small mobile workbench. Closed, it protects and carries the tools. Open, it offers a stable work surface and accessible storage.
This sentence describes an intention, not yet a product. To move to design, each word has to be turned into a checkable question.
Help me turn this idea into a project: a portable toolbox that becomes a workbench. Start by asking me the essential questions one at a time. Do not suggest any dimensions until the user, the tools carried and the main use are defined.
Why this project is a good exercise
- Everyone understands its purpose in a few seconds.
- It combines storage, ergonomics, structure, mobility and cost.
- It lets you build a simple prototype before investing.
- The results can be tested: weight, opening time, stability and access to the tools.
The possible users
Occasional DIYer
Wants compact storage, easy to move and simple to open.
Mobile technician
Often carries the whole set and needs quick access to the tools.
Tradesperson
Looks for more sturdiness, stability and modularity.
The functions to study
| Function | Project question | How to check it |
|---|---|---|
| Carry | What weight and bulk are acceptable? | Weighing, a moving test and loading into a vehicle. |
| Store | Which tools must stay immediately accessible? | Inventory and a tool-finding test. |
| Work | What surface and height are actually useful? | Full-scale mock-up and a user test. |
| Stay stable | Which actions risk tipping the whole thing over? | Careful tests at different points on the top. |
| Deploy | How many steps and how much time are acceptable? | Timing with several users. |
Five families of concepts
1. The lid becomes the top
A simple solution, but the working height depends on the base used.
2. Folding legs deploy
A good height is possible, with a locking mechanism to make safe.
3. A telescopic structure raises the box
Elegant deployment, but weight, cost and maintenance go up.
4. Several modules stack up
Very adaptable storage, at the cost of a longer assembly.
5. A top links two boxes
A large work surface, but more items to carry.
The case-study deliverables
The rule that protects the project
ChatGPT prepares, compares and documents. Reality decides.
Loads, stability, pinch points, locking and safe use must be checked on a prototype and, if needed, by a qualified person.
