Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gear engagement is used to transmit torque from driving member to output shaft, then power transmission is achieved, but transmission accuracy deteriorates due to engaging clearances between gears
Solution Approach 1:
The patent replaces the traditional gear engagement mechanism with a screw-nut mechanical transmission system. The driving member drives the screw rod to rotate, which converts rotational motion to linear motion of the screw nut, thereby driving the output shaft. This substitution eliminates gear engaging clearances and achieves higher transmission accuracy while maintaining reliable power transmission.
Solution Approach 2:
The patent changes the transmission mechanism from gear engagement to screw-nut conversion, fundamentally altering the motion transmission parameters. The screw rod converts rotational motion to linear motion with precise control, eliminating the clearance-based inaccuracies inherent in gear systems and achieving superior transmission accuracy.
2Power
If multiple gears are used in the reducer, then power transmission capability is improved, but torsion loss increases due to friction in multiple gear engagements
Solution Approach 1:
The patent replaces the multi-gear reduction system with a screw-nut transmission system. This substitution reduces the number of moving parts and engagement interfaces, thereby minimizing friction losses and improving torsion efficiency while maintaining adequate power transmission capability for the application.
3Speed
If gear-based reducer is used, then speed reduction is achieved, but transmission accuracy deteriorates due to cumulative clearance effects
Solution Approach 1:
The patent replaces the gear-based speed reduction mechanism with a screw-nut transmission system. The screw rod and nut provide precise motion conversion with minimal clearance effects, achieving accurate speed reduction and position control without the cumulative clearance errors that plague multi-stage gear systems.
