Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a motor and steering wheel are connected through a coupling, then the steering mechanism can be assembled, but the product becomes bulky and expensive, and force feedback transmission is indirect causing loss of road feeling
Solution Approach 1:
The patent merges the motor and steering wheel into a single integrated structure where the motor is mounted directly on the steering wheel assembly. This eliminates the separate coupling component and reduces the overall volume while maintaining assembly capability through integrated mounting brackets and direct mechanical connection.
2Ease of manufacture
If a motor and steering wheel are connected through a coupling, then the steering mechanism can be assembled, but force feedback transmission becomes indirect, causing loss of subtle road feeling feedback
Solution Approach 1:
The patent merges the motor and steering wheel into a single integrated structure where the motor is mounted directly on the steering wheel assembly. This eliminates the separate coupling component and reduces the overall volume while maintaining assembly capability through integrated mounting brackets and direct mechanical connection.
Solution Approach 2:
The patent introduces a magnetic coupling mechanism as an intermediary between the motor and steering wheel that transmits force feedback through magnetic fields rather than direct mechanical contact. This magnetic intermediary preserves the subtle road feeling by eliminating mechanical play and friction while still enabling force transmission.
3Use of energy by moving object
If traditional power supply systems (wireless charging, wired power supply, or built-in battery) are used, then the steering wheel can be powered, but the system becomes complex and complicated
Solution Approach 1:
The patent implements a self-service power supply system where the steering wheel generates its own power through electromagnetic induction during rotation. The rotating magnets on the motor assembly induce current in stationary coils, creating a self-charging mechanism that eliminates the need for external batteries, wireless charging receivers, or wired power connections, thereby simplifying the system.
