Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple versions of input interface are designed to optimize user experience for different environments, then user experience is improved, but design complexity and manufacturing cost increase
Solution Approach 1:
The input interface is designed as a universal device that can perform multiple functions across different environments. The interface includes a display region and a input region that can detect various input types (touch, proximity, gesture) to adapt to different user needs without requiring separate specialized devices for each function.
Solution Approach 2:
The input interface dynamically adjusts its behavior and sensitivity based on the detected input type and environmental context. The system can switch between touch mode, proximity mode, and gesture recognition mode, allowing it to optimize performance for different usage scenarios while maintaining a single unified hardware design.
2Adaptability or versatility
If multiple versions of input interface are designed to optimize user experience for different environments, then user experience is improved, but manufacturing cost increases
Solution Approach 1:
The input interface is designed as a universal device that can perform multiple functions across different environments. The interface includes a display region and a input region that can detect various input types (touch, proximity, gesture) to adapt to different user needs without requiring separate specialized devices for each function.
Solution Approach 2:
Multiple input functionalities (touch sensing, proximity detection, gesture recognition) are merged into a single integrated input interface device. This consolidation reduces the need for multiple separate components and versions, thereby lowering manufacturing costs while maintaining adaptability across different environments.
3Measurement precision
If cursor-based interaction is used to navigate menu structure, then interaction precision is improved, but driver operation safety deteriorates
Solution Approach 1:
The system replaces traditional cursor-based mechanical interaction with a rotary input mechanism that provides tactile feedback. This mechanical substitution allows drivers to interact with the interface using rotational motion and tactile cues, eliminating the need for visual attention required by cursor-based systems while maintaining precise control.
Solution Approach 2:
The rotary input mechanism provides self-service through tactile feedback and intuitive rotational control, allowing drivers to operate the interface without visual confirmation. The physical rotation and tactile response enable precise input selection without requiring the driver to watch the display, thereby maintaining safety while achieving interaction precision.
