Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pairing methods using buttons or displays are used, then pairing can be performed with user feedback, but the device complexity increases and ease of operation decreases for devices without these components
Solution Approach 1:
The patent replaces mechanical input methods (buttons, displays) with wireless communication and sensor-based detection. The mobile device uses wireless signal transmission and sensor information (accelerometer, gyroscope, magnetometer) to detect proximity and touch events, eliminating the need for physical buttons or displays on the electronic device being paired.
Solution Approach 2:
The patent introduces sensor information as an intermediary between the physical touch event and the pairing operation. The sensors detect movement, inclination, and magnetic field changes caused by touching, converting these physical actions into digital signals that trigger pairing without requiring traditional input interfaces.
2Reliability
If fixed touch thresholds are used, then the pairing decision is simple to make, but the reliability decreases when devices are touched from different positions or orientations
Solution Approach 1:
The patent makes the touch threshold dynamic by adjusting it based on sensor information. The processor calculates different thresholds depending on the detected movement pattern, inclination angle, and magnetic field changes, allowing the system to adapt to various touching positions and orientations while maintaining reliable pairing detection.
Solution Approach 2:
The patent changes the touch threshold parameter based on sensor data. Instead of using a fixed threshold, the system modifies the threshold value according to the detected inclination, movement acceleration, and magnetic field variation, ensuring accurate touch detection across different device orientations and positions.
3Adaptability or versatility
If sensor information processing is added to determine touch, then the adaptability improves for different touching scenarios, but the device complexity increases
Solution Approach 1:
The patent makes the mobile device's sensor system perform multiple functions: it detects proximity, determines touch events, calculates inclination angles, measures movement acceleration, and detects magnetic field changes. By reusing the same sensor suite for multiple detection purposes, the system achieves high adaptability without proportionally increasing complexity.
Solution Approach 2:
The patent combines multiple sensor types (accelerometer, gyroscope, magnetometer) into a unified touch detection system. The processor integrates data from all these sensors to comprehensively analyze touching events, merging their functions to achieve reliable detection across various scenarios while avoiding the need for separate dedicated sensors for each function.
4Ease of operation
If wireless signal strength threshold is used for proximity determination, then the ease of operation improves, but the measurement precision decreases due to signal variability
Solution Approach 1:
The patent uses sensor information as an intermediary to verify and supplement wireless signal strength measurements. When the signal strength indicates proximity, the sensor data (acceleration, inclination, magnetic field) provides additional confirmation of actual physical proximity, filtering out false positives caused by signal variability.
