Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed torque and speed settings are used for mounting/demounting tyres, then the apparatus structure is simple, but tyre damage occurs due to inability to adapt to different tyre stiffness
Solution Approach 1:
The patent implements dynamic adjustment of motor torque and speed during the mounting/demounting operation. The control system continuously monitors operational parameters and automatically modifies motor output to match the actual tyre stiffness and resistance encountered, transforming the previously static motor control into a dynamic adaptive system that prevents tyre damage while managing complexity through automated feedback control
Solution Approach 2:
The patent changes the operational parameters (torque and speed) of the electric motor based on detected tyre characteristics and operational progress. By adjusting these parameters in real-time according to tyre stiffness and mounting stage, the system adapts to different tyre types without requiring complex mechanical modifications, resolving the contradiction between reliability and device complexity
2Adaptability or versatility
If manual torque adjustment by operator is used, then adaptability to different tyre types is achieved, but operation time increases and consistency decreases
Solution Approach 1:
The patent incorporates a feedback control system that monitors motor current, torque, and speed during operation. This feedback enables the control system to automatically detect tyre stiffness characteristics and adjust parameters in real-time, eliminating the need for manual assessment and adjustment by the operator. The automated feedback loop maintains adaptability while significantly reducing operation time and improving consistency
Solution Approach 2:
The control system performs self-adjustment based on operational feedback, automatically adapting to different tyre types without requiring operator intervention. The system monitors its own performance parameters and makes necessary corrections autonomously, transforming the manual adjustment process into a self-service automated system that reduces time loss while maintaining versatility
3Force
If high motor torque is applied to handle stiff tyres, then mounting capability is improved, but tyre damage risk increases for softer tyres
Solution Approach 1:
The patent applies dynamic torque adjustment where the motor torque is continuously adapted during the mounting operation based on real-time feedback from current sensors and motor performance monitoring. For stiff tyres, the system automatically increases torque to sufficient levels, while for softer tyres, it reduces torque to prevent damage, eliminating the need to use high torque for all tyre types
Solution Approach 2:
The control system changes the torque parameter dynamically based on detected tyre characteristics and operational progress. By monitoring motor current and mechanical resistance, the system automatically adjusts torque levels to match the specific requirements of each tyre type, ensuring sufficient force for stiff tyres while preventing excessive torque application to softer tyres
4Reliability
If continuous monitoring and automatic adjustment of torque and speed is implemented, then tyre damage is prevented, but energy consumption increases
Solution Approach 1:
The patent optimizes energy consumption by adjusting motor parameters (torque and speed) to match actual operational requirements rather than maintaining constant high settings. The control system monitors tyre stiffness and mounting progress, then adjusts torque and speed to the minimum necessary levels for each stage, preventing tyre damage while avoiding unnecessary energy consumption during low-resistance operations
