Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If camera-based gesture detection is used to control remote controller, then gesture recognition capability is improved, but user privacy is compromised and resource consumption increases
Solution Approach 1:
The patent replaces camera-based visual detection with infrared detection systems that sense gestures through infrared radiation. This substitution eliminates the need for cameras that capture and store images, thereby removing the privacy infringement while maintaining gesture recognition capability. The infrared detection system processes only the necessary gesture information without capturing personal visual data.
2Reliability
If multiple infrared detection systems are used to improve gesture recognition accuracy, then control reliability is improved, but system complexity and resource consumption increase
Solution Approach 1:
The patent divides the detection system into multiple independent infrared detection systems, each responsible for detecting gestures in specific spatial zones. This segmentation allows the system to achieve high recognition accuracy through distributed detection while managing complexity by assigning specific functions to each detector. The controller coordinates these segmented systems to work together, reducing overall system complexity compared to a single complex detection system.
Solution Approach 2:
The patent employs multiple infrared detection systems that may detect the same gesture from different positions. The controller then filters and selects the most relevant detection results based on pre-set rules, avoiding the need to process all detection data equally. This partial action approach reduces resource consumption by focusing only on the most relevant detection results while maintaining high recognition accuracy through the redundant detection systems.
3Measurement precision
If network connectivity is required for audio recognition, then recognition accuracy is improved, but system reliability deteriorates in offline environments
Solution Approach 1:
The patent pre-loads audio recognition models and gesture detection algorithms into the controller before offline operation is needed. The controller stores local copies of the audio recognizing model and gesture matching rules, enabling accurate audio and gesture recognition without requiring network connectivity. This preliminary action ensures the system maintains high recognition accuracy while being fully functional in offline environments.
