Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measurement methods are used for optical and electrical characteristics, then each characteristic can be measured individually, but they cannot be measured at the same time
Solution Approach 1:
The patent combines optical measurement components (CCD camera, light source) and electrical measurement components (electrodes, force detecting units) into a single integrated clip device. This merging allows both optical and electrical characteristics to be measured simultaneously at the same location on the flexible device, resolving the contradiction between simultaneous measurement capability and system integration complexity.
Solution Approach 2:
The clip device is designed with multi-functionality, serving as both a mechanical fixture for holding the flexible device and a measurement platform that simultaneously performs optical imaging and electrical characteristic detection. The electrodes are integrated into the clipping heads, allowing electrical measurements to be taken at the exact same position where optical measurements occur, achieving universal measurement capability.
2Measurement precision
If contact-type measurement is used for bending forces, then mechanical characteristics can be detected, but electrical characteristics cannot be measured simultaneously
Solution Approach 1:
The patent merges contact-type mechanical measurement (force detecting units in the clipping heads) with electrical measurement (electrodes on the clipping heads) into a single operational step. Both types of measurements are performed simultaneously through the same clipping action, eliminating the need for separate measurement processes and maintaining operational simplicity while adding electrical detection capability.
3Measurement precision
If roll-to-roll mechanism with electrodes is used for electrical characteristics measurement, then electrical field can be built up during manufacturing, but optical and electrical characteristics cannot be measured at the same time
Solution Approach 1:
The patent segments the measurement functions into distinct modules within the clip device: force detecting units for mechanical measurement, electrodes for electrical measurement, and integrated imaging capability for optical measurement. This segmentation allows each measurement type to be performed independently yet simultaneously, achieving comprehensive measurement capability while maintaining a manageable device structure through modular design.
