Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional touch click operations are used for function selection, then the device can perform multiple functions, but the operation complexity increases and accuracy decreases
Solution Approach 1:
The patent replaces the mechanical touch click operation system with a thermal sensing system. Instead of relying on mechanical touch events that require precise positioning and multiple clicks, the system uses thermal fields to detect touch operations. The thermal sensing acquisition module captures thermal distribution curves that naturally form when a user touches different areas, eliminating the need for complex sequential touch operations while maintaining multi-function selection capability.
Solution Approach 2:
The patent changes the detection parameter from mechanical touch position to thermal distribution characteristics. By monitoring how heat distributes across the touch surface during a single touch operation, the system can identify different touch patterns (single touch, double touch, sliding touch) and map them to different functions. This parameter change simplifies the operation from multiple sequential clicks to a single touch gesture while preserving adaptability.
2Adaptability or versatility
If multiple touch clicks are required for function selection, then various functions can be accessed, but the operation time increases
Solution Approach 1:
The system performs preliminary classification of touch operations by analyzing thermal distribution patterns immediately upon touch detection. The thermal sensing acquisition module continuously monitors thermal fields, and when a touch occurs, the system instantly captures the thermal distribution curve and compares it against pre-stored reference patterns. This preliminary action allows the system to determine the intended function before the user completes the touch gesture, significantly reducing operation time while maintaining access to multiple functions.
Solution Approach 2:
The replacement of mechanical sequential clicking with thermal field-based single-touch recognition eliminates the time required for multiple discrete click actions. The thermal sensing system captures the entire touch pattern in a single continuous measurement, allowing instant function determination without waiting for sequential user inputs.
3Measurement precision
If precise touch clicking is required for function selection, then accurate function activation is achieved, but the operation flexibility decreases
Solution Approach 1:
The patent applies local quality analysis by examining the thermal distribution characteristics at different locations on the touch surface. Instead of requiring precise global touch positioning, the system analyzes local thermal patterns - such as which specific sensors detect heat, the intensity distribution across adjacent sensors, and the spatial gradient of thermal energy. This local quality approach allows flexible touch positions while maintaining accurate function identification.
Solution Approach 2:
The thermal sensing system provides universal function recognition by mapping multiple thermal distribution patterns to different functions. A single touch operation can generate various thermal patterns depending on touch location, duration, and movement, and the system universally handles all these patterns to activate appropriate functions. This universal approach increases flexibility while maintaining precision through pattern recognition rather than position-dependent activation.
