Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the position of menu icons on the touch panel is fixed, then the device structure is simple and easy to manufacture, but the user cannot change the icon positions which reduces adaptability and user satisfaction
Solution Approach 1:
The system allows users to freely move icon members to desired positions on the touch panel without requiring technical assistance or complex reconfiguration procedures. The sensor automatically detects the new positions and the processor adapts the interface accordingly, enabling users to self-customize their interface layout.
Solution Approach 2:
The icon members are designed to be movable rather than fixed, allowing dynamic repositioning by users. The system transitions from a static interface layout to a dynamic one where icon positions can be changed according to user preferences and usage patterns.
2Measurement precision
If multiple icon members with different permittivity are used to enable position detection, then the sensing precision is improved, but the manufacturing complexity increases
Solution Approach 1:
Different regions of the icon members or panel have different permittivity characteristics. This local variation in material properties enables the sensor to distinguish between different icon members and accurately detect their positions based on capacitance changes when touched.
Solution Approach 2:
The system utilizes changes in capacitance parameters caused by different permittivity values of icon members to detect touch positions. By measuring the capacitance change when an icon member is touched, the processor can identify which icon was selected even when multiple icons are present.
3Ease of operation
If the system uses capacitance change detection to identify touched icons, then the ease of operation is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The system replaces complex mechanical or optical detection mechanisms with electrical capacitance sensing. The sensor detects changes in capacitance caused by finger touches, which are then processed to identify the touched icon member, providing a simple and responsive touch interface.
