Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual measurement methods are used for blades, then measurement can be performed with simple equipment, but work efficiency is low and measurement time is excessive
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated measurement device that uses sensors and image processing technology. The measurement unit captures images of the blade and automatically calculates physical amounts through image analysis, eliminating the need for manual measurement operations and significantly improving work efficiency while reducing measurement time
Solution Approach 2:
The measurement device enables self-service measurement where the system automatically performs measurement tasks without human intervention. The blade is placed on the placement portion and the measurement unit automatically captures images and calculates physical amounts, allowing the system to serve itself in the measurement process and thereby improving productivity
2Productivity
If automated measurement systems are implemented, then work efficiency improves, but device complexity increases
Solution Approach 1:
The measurement device integrates multiple functions into a single system: the placement portion serves as both a support structure and a positioning mechanism, the image capturing unit performs both image acquisition and preliminary analysis, and the calculation unit handles multiple physical amount calculations. This multi-functionality improves work efficiency while controlling device complexity by consolidating operations
Solution Approach 2:
The patent introduces an image as an intermediary between the physical blade and the measurement calculation. Instead of direct complex mechanical measurements, the system captures an image of the blade and uses image processing to derive physical amounts. This intermediary approach simplifies the measurement system while maintaining high productivity
