Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical reversal mechanism with fixed stops is used, then the reversal function is achieved, but significant shock and wear are introduced into the drive
Solution Approach 1:
The patent replaces the traditional mechanical reversal mechanism with a motor-driven system. The motor rotates the rolling rings to change their pitch angle, enabling direction reversal without mechanical contact with fixed stops. This substitution eliminates the shock and wear problems inherent in mechanical systems while achieving the same reversal function.
Solution Approach 2:
The patent changes the operational parameters of the rolling rings by dynamically adjusting their pitch angle through motor rotation. Instead of using fixed mechanical stops, the system varies the pitch parameter continuously to achieve smooth direction reversal, thereby eliminating冲击 and wear associated with abrupt mechanical contact.
2Ease of operation
If a mechanical reversal mechanism is used, then direction reversal is achieved, but considerable wear occurs on the reversal mechanism
Solution Approach 1:
The patent replaces the traditional mechanical reversal mechanism with a motor-driven system. The motor rotates the rolling rings to change their pitch angle, enabling direction reversal without mechanical contact with fixed stops. This substitution eliminates the shock and wear problems inherent in mechanical systems while achieving the same reversal function.
3Object-affected harmful factors
If a motor-controlled system is used to adjust pitch, then smooth reversal is achieved, but device complexity increases
Solution Approach 1:
The patent replaces the traditional mechanical reversal mechanism with a motor-driven system. The motor rotates the rolling rings to change their pitch angle, enabling direction reversal without mechanical contact with fixed stops. This substitution eliminates the shock and wear problems inherent in mechanical systems while achieving the same reversal function.
Solution Approach 2:
The patent incorporates a control system that monitors the position and operation of the rolling rings, enabling precise adjustment of the pitch angle. This feedback mechanism ensures smooth direction reversal by continuously adjusting motor operation based on actual system state, thereby eliminating the need for complex mechanical linkages while maintaining control precision.
