Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional touch sensors are used for user input, then the device structure remains simple, but 3D gesture recognition capability is lost
Solution Approach 1:
The gesture sensing unit is segmented into multiple light-emitting units (first and second) and a light-receiving unit, each performing specific functions. This segmentation enables 3D gesture recognition by dividing the sensing task into multiple coordinated components, resolving the contradiction between enhanced capability and structural simplicity.
Solution Approach 2:
Multiple light-emitting units and a light-receiving unit are merged into an integrated gesture sensing unit that works cooperatively. This merging allows the system to achieve 3D gesture recognition capability while maintaining a unified, manageable structure, balancing versatility and complexity.
2Measurement precision
If a single light-emitting unit is used, then the device structure remains simple, but the recognition rate of 3D gestures decreases
Solution Approach 1:
The light-emitting function is segmented into multiple independent light-emitting units that emit light along different optical paths. This segmentation improves measurement precision by providing multiple viewing angles and light paths for detecting 3D gestures, while keeping each individual unit relatively simple.
Solution Approach 2:
Multiple light-emitting units are arranged to emit light along different optical paths, adding spatial dimensionality to the sensing capability. This dimensional approach enhances 3D gesture recognition accuracy by capturing gesture information from multiple angles simultaneously.
3Measurement precision
If multiple optical paths are used for ray emission, then 3D gesture detection accuracy improves, but the device complexity increases
Solution Approach 1:
The optical sensing is segmented into multiple distinct optical paths, each handled by dedicated light-emitting and light-receiving units. This segmentation improves detection accuracy by allowing independent optimization of each optical path while maintaining overall system manageability.
