Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice control is used for vehicle mounted atomizer, then control operation is simplified, but environmental noise interference increases and recognition rate decreases
Solution Approach 1:
The patent replaces voice control (acoustic field) with gesture control (optical field). The light emitting component emits infrared light and the position sensor detects the reflected light to determine hand gestures, substituting the acoustic-based voice control system with an optical-based gesture recognition system that is not affected by environmental noise.
Solution Approach 2:
The patent introduces infrared light as an intermediary carrier for gesture detection. The light emitting component and position sensor use infrared light to detect hand gestures, creating an intermediary optical communication channel that is immune to environmental noise interference affecting voice control.
2Measurement precision
If button operation is used for vehicle mounted atomizer, then control precision is maintained, but operation complexity increases and safety decreases
Solution Approach 1:
The patent replaces mechanical button operation with optical gesture recognition. The position sensor detects the position of the reflected infrared light to determine hand gestures, eliminating the need for physical button presses while maintaining control precision through accurate optical positioning.
Solution Approach 2:
The system uses the user's own hand gestures as the control interface, eliminating the need for separate control buttons. The gesture control system interprets natural hand movements directly as control commands, simplifying the interaction while maintaining precision through optical detection.
3Ease of operation
If voice control is used in noisy vehicle environment, then hands-free operation is achieved, but control reliability decreases due to noise interference
Solution Approach 1:
The patent substitutes acoustic-based voice control with optical-based gesture control. The infrared light detection system is completely immune to the environmental noise (engine noise, wind noise, road noise) that plagues voice recognition in vehicles, while still enabling hands-free operation through natural hand gestures.
Solution Approach 2:
The patent acknowledges that vehicle environments are inherently noisy for voice control, and converts this harmful environmental factor into a benefit by using an optical detection system that thrives in such conditions. The gesture control system actually benefits from the same vehicle environment that harms voice control, as infrared light detection is unaffected by acoustic noise.
