Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate measurement device is used to measure the radius of the test target, then the measurement accuracy is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the radius measurement function with the imaging detector by integrating a bending sensor directly into the detector structure. The bending sensor is embedded in the reinforcement part of the detector housing, allowing the detector to simultaneously perform imaging and radius measurement without requiring separate measurement devices, thus reducing overall system complexity while maintaining measurement accuracy
Solution Approach 2:
The detector is designed with multi-functionality by incorporating both imaging capabilities and radius measurement capabilities into a single device. The bending sensor integrated into the detector housing enables the detector to measure the radius of curved test targets while simultaneously capturing images, making the device universal and eliminating the need for separate specialized measurement instruments
2Measurement precision
If a separate measurement device is used to detect curvature changes, then the detection accuracy is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent merges the curvature detection function with the imaging detector by integrating a bending sensor that directly measures curvature changes. The bending sensor is positioned within the detector housing to detect curvature of the detector itself during imaging operations, allowing simultaneous detection and imaging without requiring separate measurement operations or devices
Solution Approach 2:
The detector performs self-measurement of its own curvature changes through the integrated bending sensor. The detector automatically detects its own bending degree during imaging operations without requiring external measurement devices or additional operational steps, making the operation simpler and more intuitive
3Adaptability or versatility
If the detector housing is made entirely of elastic material to allow bending, then the adaptability to curved surfaces is improved, but the structural strength and stability deteriorate
Solution Approach 1:
The detector housing employs local quality by using different materials for different functional regions. The first housing portion that contacts the test target is made of elastic material to allow bending and adapt to curved surfaces, while the second housing portion is made of rigid material to provide structural strength and stability. This localized material differentiation allows each part to fulfill its specific functional requirements
Solution Approach 2:
The detector housing uses a composite structure combining elastic and rigid materials in different sections. The first housing is made of elastic material for flexibility and adaptability to curved surfaces, while the second housing is made of rigid material for structural support. This composite construction allows the overall structure to simultaneously achieve both flexibility where needed and strength where required
4Measurement precision
If the reinforcement part is divided into multiple parts to accommodate bending sensors, then the measurement capability is improved, but the manufacturing complexity increases
Solution Approach 1:
The reinforcement part is segmented into multiple sections with bending sensors positioned at different locations along the reinforcement structure. This segmentation allows the detector to measure bending at multiple points, providing more comprehensive curvature information and improved measurement capability, while the modular sensor placement facilitates targeted manufacturing and assembly
