Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sphere mechanism is rotated to change modes in an electronic shift system, then the shifting unit and design unit can be positioned to alter vehicle interior appearance and functionality, but the sphere mechanism may separate from the rotation completion location causing clearance and noise
Solution Approach 1:
The control unit continuously monitors the rotation angle of the sphere mechanism and compares it with the target rotation completion location. When a deviation is detected, the control unit generates a correction signal to adjust the motor's rotation, ensuring the sphere mechanism returns to the precise completion location. This feedback loop maintains positioning accuracy while enabling mode changes.
Solution Approach 2:
The control unit determines the rotation completion location in advance based on predetermined rotation angles before initiating the rotation. By pre-calculating the target position and preparing correction protocols, the system ensures accurate positioning is achieved without deviation during the mode changing process.
2Ease of operation
If the motor drives the sphere mechanism to rotate for mode changing, then the shifting apparatus can transition between different positions, but clearance and noise occur due to separation from the rotation completion location
Solution Approach 1:
The control unit monitors the actual rotation position of the sphere mechanism and compares it with the target completion location. When separation is detected, the control unit generates a correction signal to adjust the motor's rotation, ensuring the sphere mechanism returns to the precise completion location. This feedback loop eliminates clearance and prevents noise generation during mode transitions.
Solution Approach 2:
The control unit applies preliminary correction signals before clearance can occur by continuously monitoring rotation position. By detecting deviations early and applying corrective rotation, the system prevents clearance formation and the associated noise, maintaining smooth operation throughout the mode transition process.
