Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If contact measurement method is used, then measurement can be performed with simple equipment, but the surface may be scratched and errors occur
Solution Approach 1:
The patent replaces the mechanical contact measurement system (thickness gauge and cursor caliper) with an optical measurement system (camera and image processing). The optical system captures images of the gap between the battery cover and main body, then uses image scanning operations to measure the gap breadth without physical contact, thereby eliminating surface scratching while maintaining measurement capability
Solution Approach 2:
The patent creates an optical copy (image) of the gap rather than physically measuring it. The camera captures an image of the gap, and the image processing device analyzes this copy to determine the gap breadth. This copying approach allows measurement without direct physical contact with the actual gap, preventing surface damage
2Device complexity
If contact measurement method is used, then equipment is simple, but measurement time is increased and effort is required
Solution Approach 1:
The patent replaces manual mechanical measurement operations with automated optical capture and digital image processing. The camera automatically captures the gap image, and the image processing device automatically scans and measures the gap breadth through programmed operations, eliminating manual effort and significantly reducing measurement time
Solution Approach 2:
The measurement system performs self-service through automated image capture and processing. Once the camera captures the gap image, the image processing device automatically executes scanning operations to measure the gap breadth without requiring continuous manual intervention, thereby improving measurement efficiency and reducing human effort
3Device complexity
If contact measurement method is used, then equipment is simple, but measurement precision is reduced due to errors
Solution Approach 1:
The patent creates a precise optical copy (digital image) of the gap that can be analyzed without the limitations of manual measurement. The image capture device records the gap dimensions with high fidelity, and the image processing device accurately measures the gap breadth from this copy, eliminating human reading errors and improving measurement precision
Solution Approach 2:
The patent replaces error-prone manual mechanical measurement with automated optical measurement and digital image analysis. The systematic image scanning operations provide consistent, repeatable measurements without the human errors associated with manual reading and recording, thereby improving measurement precision
