Engineering Contradiction Analysis
1Measurement precision
If manual tape testing method is used, then operation simplicity is maintained, but measurement precision and reliability deteriorate due to human error in tape application and angle
Solution Approach 1:
The patent replaces the manual mechanical tape testing method with an automated mechanical testing apparatus that applies tape at precise angles and pressures through mechanical means, eliminating human error in tape application while maintaining operational simplicity through automation
Solution Approach 2:
The patent controls and standardizes critical parameters including tape application angle, pressing force, and peeling speed through the mechanical apparatus, transforming the variable manual process into a controlled parameter-driven process that ensures measurement precision
2Productivity
If automated testing is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent implements full automation of the tape testing process through a mechanical apparatus that automatically applies tape, controls pressing force, and performs peeling tests, significantly improving productivity by eliminating manual intervention while the self-contained mechanical design keeps the added complexity manageable
Solution Approach 2:
The automated testing apparatus is designed to perform all testing operations autonomously without requiring external intervention or complex control systems, allowing the device to serve itself in completing the full testing cycle and thereby improving productivity without proportionally increasing complexity
3Measurement precision
If quantitative measurement is used, then measurement precision is improved, but ease of operation deteriorates due to complex analysis requirements
Solution Approach 1:
The patent replaces subjective visual assessment with an automated optical measurement system that quantitatively measures peeling area through image analysis, achieving precise quantification while the automated nature of the system maintains ease of operation by eliminating manual measurement and calculation steps
Solution Approach 2:
The patent uses optical imaging to create a visual copy of the peeling pattern, which is then automatically analyzed through image processing algorithms, allowing for precise quantitative measurement without requiring manual intervention in the analysis process and thereby maintaining ease of operation
4Measurement precision
If consistent tape application is enforced, then measurement precision is improved, but ease of operation worsens due to strict procedural requirements
Solution Approach 1:
The patent transforms the operational flexibility of manual tape application into controlled parameter consistency by fixing the tape application angle, pressing force, and peeling speed as controlled parameters in the automated apparatus, ensuring measurement precision through parameter standardization while the automation handles the strict procedural requirements
