Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual spraying with repeated adjustments is used, then spraying thickness can be controlled, but labor intensity increases and production efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical spraying operations with an automated spraying system that uses sensors to detect tire inner wall positions and a controller to automatically adjust spraying parameters. This substitution eliminates manual labor while maintaining precise thickness control through automated feedback mechanisms.
Solution Approach 2:
The patent implements a feedback control system where sensors continuously monitor the spraying thickness and tire inner wall position, and the controller adjusts the spraying amount in real-time based on this feedback. This ensures precise thickness control without requiring manual measurement and adjustment iterations.
2Productivity
If automated spraying is implemented, then production efficiency improves, but adaptability to different tire specifications decreases
Solution Approach 1:
The patent employs a dynamic spraying system where the spraying parameters are not fixed but are automatically adjusted in real-time based on detected tire characteristics. The controller modifies spraying amount, speed, and position dynamically to adapt to different tire specifications while maintaining automated operation.
Solution Approach 2:
The patent changes spraying parameters (amount, speed, position) based on detected tire specifications. The system automatically adjusts these parameters according to the specific tire being sprayed, enabling both high productivity and adaptability to different tire types.
3Manufacturing precision
If repeated measurement and adjustment operations are performed, then spraying quality is improved, but production time increases
Solution Approach 1:
The patent performs preliminary detection of tire inner wall position and specifications before spraying begins. The controller pre-calculates the optimal spraying parameters based on this preliminary information, eliminating the need for repeated measurement and adjustment operations during the spraying process.
Solution Approach 2:
The patent implements continuous spraying without interruption or repeated stopping for measurements. The automated system maintains continuous operation while sensors and controllers continuously monitor and adjust parameters, ensuring both high quality and reduced production time.
