Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated frame-removing devices are used, then productivity is improved, but manufacturing precision deteriorates due to frame deformations
Solution Approach 1:
The device changes the parameter of force distribution by using multiple pressing points instead of single-point impact, transforming the removal mechanism from high-force impact to distributed controlled pressure, thereby preventing frame deformation while maintaining automated processing speed
Solution Approach 2:
The frame removal process is segmented into multiple independent pressing actions at different locations along the frame, allowing controlled detachment at each segment rather than uncontrolled impact, which prevents deformation while maintaining productivity
2Manufacturing precision
If manual hammer removal is used, then manufacturing precision is maintained, but productivity deteriorates due to long processing time
Solution Approach 1:
The manual hammering mechanical system is replaced with an automated controlled pressing system that uses distributed force application, achieving both the precision of manual control and the speed of automation through programmable multi-point pressing
3Productivity
If force is applied to remove the frame, then productivity is improved, but object-affected harmful factors increase due to glass damage and layer crushing
Solution Approach 1:
The force application parameters are changed from high-magnitude impact forces to distributed low-magnitude pressing forces applied simultaneously at multiple points, achieving frame removal through cumulative effect rather than impact, thereby preventing glass damage while maintaining removal speed
