Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional steering column structure is used, then the structure is simple, but the steering becomes heavy and causes wear due to non-coaxial alignment from manufacturing and assembly errors
Solution Approach 1:
The patent employs a spherical bearing structure with a球面 (spherical surface) that allows the steering column to rotate and swing in multiple directions. This curved spherical interface compensates for manufacturing and assembly errors by accommodating misalignment through multi-directional movement, thereby reducing wear and improving steering ease without requiring complex adjustment mechanisms.
Solution Approach 2:
The steering column is designed with dynamic movement capabilities through the spherical bearing, allowing it to swing and rotate at any angle rather than being rigidly fixed. This dynamic adjustment capability enables the system to adapt to misalignment conditions, reducing friction and wear while maintaining smooth steering operation.
2Ease of manufacture
If a fixed steering column structure is used, then the assembly is simple, but manufacturing and assembly errors cause non-coaxial alignment leading to heavy steering
Solution Approach 1:
The spherical bearing provides a built-in compensation mechanism that tolerates misalignment errors. The spherical surface geometry allows the steering column to achieve proper coaxial alignment through multi-directional swinging and rotating movements, eliminating the need for extremely precise manufacturing and assembly while maintaining steering performance.
Solution Approach 2:
The system changes the operational parameters of the steering column by allowing it to swing and rotate at any angle within the spherical bearing. This parameter flexibility enables the steering column to adjust its position and orientation to achieve proper alignment despite manufacturing and assembly variations, maintaining precision without requiring complex control systems.
3Stability of the object's composition
If the steering column is rigidly fixed, then the structure is stable, but long-term use causes wear to fixing parts affecting driving safety
Solution Approach 1:
The spherical bearing enables dynamic movement of the steering column, allowing it to swing and rotate to compensate for misalignment. This dynamic capability reduces the stress and friction on fixing parts during operation, thereby reducing wear while maintaining structural stability. The system achieves both stability through the bearing structure and wear reduction through controlled movement.
