| Usage problem | Convert to TRIZ standard question | TRIZ innovation theory and method | Method of choice | Corresponding practical operation |
|
| 1. The safety protection is not in place and the neck is easily injured | 11. Stress or pressure
2. Mass of a stationary object | 13, 29, 10, 18 | 10. Preoperation
29. Pneumatic and hydraulic structure | The protection of the neck is done by airbags. |
| 2. The helmet body is slightly heavier | 2. Mass of stationary objects
39. Productivity | 1, 28, 15, 35 | 1. Divide | Each functional module is designed through the principle of division. |
| 3. The lens cannot be cleaned and refreshed in real time when it rains, blocking the sight | 38. Degree of automation
32. Manufacturability | 8, 28, 1 | 1. Divide | The lens device is moved to the inner side of the helmet body, and a cleanable cleaning device is set at the same time. Every time the lens is stowed, it will be cleaned. |
| 4. Adapt to the head circumference | | | | |
| 5. Communication and other functions are difficult to use while driving | 33. Operability
36. Complexity of the device | 27, 9, 26, 24 | 24. Intermediary principle | Because the interactive operation device with communication and other functions is not suitable for being placed on the helmet, the interactive operation device is designed separately and placed near the handlebar according to the intermediary principle. |
