Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact-based operation is used, then operational simplicity is maintained, but hygiene and safety are compromised
Solution Approach 1:
The patent replaces mechanical contact-based operation with optical field-based operation. Light-emitting devices and light-receiving devices are integrated into the display panel, enabling the system to detect objects and infer their positions through optical interactions without physical contact. This substitution of mechanical interaction with optical field interaction achieves contactless operation while maintaining operational functionality.
2Reliability
If multiple separate components (display, sensor, light source) are used, then functional reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges previously separate components (display panel, light-emitting devices, light-receiving devices, and processing units) into an integrated structure. The light-emitting and light-receiving devices are embedded within the display panel itself, and the processing portion is integrated with the display apparatus. This merging reduces the number of separate components while maintaining all necessary functions through shared structural elements.
Solution Approach 2:
The display panel serves multiple functions simultaneously: it acts as both the display interface and the sensor array. The light-emitting devices serve dual purposes of display illumination and active illumination for sensing. The light-receiving devices function both as touch sensors and as components for inferring object positions. This multi-functionality reduces component count while maintaining functional reliability.
3Measurement precision
If high-resolution light detection is implemented, then measurement precision is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent segments the detection function into multiple discrete light-receiving devices arranged in specific patterns (e.g., matrix arrangements, alternating patterns with light-emitting devices). Each light-receiving device can be manufactured using standard semiconductor fabrication processes, and their collective arrangement achieves high-resolution detection. This segmentation allows high precision to be achieved through the coordinated operation of multiple simpler components rather than requiring a single complex high-precision device.
