Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture recognition technology is used to control vehicle components, then convenience is improved, but measurement precision is insufficient for distinguishing specific gestures and passenger conditions
Solution Approach 1:
The patent combines multiple sensing technologies (Wi-Fi communication module for gesture recognition, light intensity sensors, motion sensors, infrared sensors, and cameras) into an integrated control apparatus. This merging of multiple sensing modalities enables comprehensive detection of passenger conditions and gestures with high precision, resolving the contradiction between ease of operation and measurement precision.
Solution Approach 2:
The patent introduces a processor as an intermediary that receives and analyzes signals from multiple sensors, including reflection signals from the Wi-Fi communication module and sensing signals from various detectors. This intermediary processing layer enables precise differentiation of gestures and passenger conditions, transforming raw sensor data into accurate control commands while maintaining user convenience.
2Measurement precision
If comprehensive sensing capabilities are added to distinguish passengers and control vehicle components, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The Wi-Fi communication module serves multiple functions: it provides wireless communication capabilities and simultaneously acts as a gesture recognition sensor by analyzing reflection signals. This multi-functionality reduces the need for separate dedicated sensors, thereby maintaining measurement precision while reducing overall device complexity.
Solution Approach 2:
The control apparatus is segmented into distinct functional modules (Wi-Fi communication module, light intensity sensor, motion sensor, infrared sensor, camera, processor, and controller), each responsible for specific sensing or processing tasks. This modular segmentation allows the system to achieve comprehensive detection capabilities while managing complexity through organized, independent functional units that can be developed and maintained separately.
3Measurement precision
If beamforming technique is used to transmit signals to specific positions, then measurement precision is improved for gesture recognition, but use of energy increases
Solution Approach 1:
The beamforming technique concentrates transmission energy into focused directional beams targeting specific positions where passengers are located, rather than distributing energy uniformly in all directions. This local concentration of energy achieves high-precision gesture recognition at the target location while minimizing energy waste in other areas, thus resolving the contradiction between measurement precision and energy consumption.
