Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video-processed gesture recognition is used for dimming control, then gesture detection capability is improved, but processing power consumption increases significantly
Solution Approach 1:
The patent replaces video-processed gesture recognition (complex optical processing) with an infrared sensor-based detection system. The IR sensor directly detects thermal radiation from gestures without requiring video processing, thereby maintaining gesture detection capability while significantly reducing processing power consumption and computational resource requirements.
Solution Approach 2:
The patent extracts only the essential thermal radiation detection component from the complex video processing system. By using an infrared sensor that specifically detects thermal signatures of gestures, the system isolates the critical detection function while eliminating the computationally intensive video processing requirements.
2Use of energy by moving object
If proximity sensors are used for dimming control, then power consumption is reduced, but resolution and sensitivity decrease
Solution Approach 1:
The patent changes the detection parameter from simple proximity measurement to thermal radiation detection. The infrared sensor measures the thermal energy emitted by gestures, providing higher resolution and sensitivity data about gesture characteristics while maintaining low power consumption compared to video processing systems.
Solution Approach 2:
The patent substitutes low-resolution proximity sensing with high-resolution thermal radiation detection. The IR sensor captures detailed thermal signature information from gestures, providing superior resolution and sensitivity while consuming minimal power compared to both video processing and traditional proximity sensors.
3Ease of operation
If physical control components are used for dimming, then ease of operation is maintained, but mechanical stress and wear increase
Solution Approach 1:
The patent replaces mechanical control components (buttons, switches, touch panels) with an optical/infrared sensing system. The IR sensor detects gestures in the air space above the device, eliminating physical contact and mechanical wear while maintaining responsive control operation through gesture recognition.
Solution Approach 2:
The patent introduces an infrared sensor as an intermediary between the user and the control system. Instead of direct physical contact with mechanical components, the user performs gestures in the air, and the IR sensor mediates the detection and translation of these gestures into control commands, eliminating mechanical stress entirely.
