Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed touch threshold value is used, then the device structure remains simple, but touch detection accuracy deteriorates in varying environments
Solution Approach 1:
The patent implements dynamic adjustment of the touch threshold value based on environmental conditions detected by the radar system. The processor continuously monitors environmental parameters and automatically modifies the touch threshold to maintain optimal detection accuracy across varying conditions, transforming a static parameter into a dynamic one that adapts to environmental changes.
Solution Approach 2:
The radar system provides environmental feedback to the processor, which then adjusts the touch threshold accordingly. This closed-loop feedback mechanism ensures that touch detection accuracy is maintained by continuously comparing actual environmental conditions with optimal threshold values and making real-time adjustments.
2Measurement precision
If environmental recognition is added, then touch detection accuracy improves, but device complexity increases
Solution Approach 1:
The radar system serves multiple functions: it detects environmental conditions for touch threshold adjustment, tracks object positions, and provides spatial awareness. By making the radar a multi-functional component, the patent avoids adding separate environmental sensors, thereby improving touch detection accuracy without proportionally increasing device complexity.
Solution Approach 2:
The existing radar infrastructure is leveraged to provide environmental recognition services for touch detection. Rather than adding dedicated environmental sensing capabilities, the system repurposes the radar's existing environmental data collection and processing functions to serve the touch detection needs, reducing the burden of additional system components.
3Adaptability or versatility
If dynamic threshold adjustment is implemented, then touch sensitivity in varying environments improves, but processing requirements increase
Solution Approach 1:
The system implements partial environmental parameter monitoring, focusing only on the specific parameters that most significantly impact touch detection accuracy. Rather than processing all available radar data, the processor selectively adjusts thresholds based on the most critical environmental factors, reducing computational overhead while maintaining adaptability.
Solution Approach 2:
The patent adjusts discrete threshold parameter values based on environmental conditions rather than performing complex real-time calculations. By pre-defining threshold values for different environmental states and simply selecting the appropriate value based on current conditions, the system achieves high adaptability with minimal processing requirements.

AI summary
An electronic device includes memory storing instructions, a radar configured to transmit an electromagnetic signal and receive a radar signal which is a reflected signal of the electromagnetic signal, the reflected signal being reflected from at least one target object, a touch pad configured to detect a touch of a user based on a designated touch threshold value, and at least one processor operatively coupled with the memory, the radar, and the touch pad. The instructions may, when executed by the at least one processor, cause the electronic device to: obtain the radar signal received by the radar; identify, based on the radar signal, a surrounding environment of the electronic device, and adjust the touch threshold value based on the surrounding environment.
