Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional physical buttons, knobs, or touch panels are used for vehicle device operation, then the device can be operated manually, but it cannot provide appropriate touch modes and determination conditions for diverse user features, postures, and identities
Solution Approach 1:
The system dynamically adjusts the trigger position of the human-computer interaction interface based on real-time sensing of user spatial information, posture, and identity. The control unit modifies the trigger position coordinates according to compensation signals generated from sensing data, enabling the interface to adapt to different user scenarios rather than using a fixed trigger position
Solution Approach 2:
The patent replaces traditional mechanical operation methods (physical buttons, knobs) with an intelligent system that uses sensing units to detect user information and a control unit to generate adaptive trigger positions. This substitution enables the system to understand user context and provide appropriate touch modes automatically, improving both adaptability and ease of operation
2Measurement precision
If the trigger position of the human-computer interaction interface is fixed, then the system structure is simple, but it cannot accurately determine touch operations for different user postures and spatial positions
Solution Approach 1:
The system divides the touch determination process into distinct functional modules: sensing units for detecting spatial information, a response unit for determining touch conditions, a compensation unit for generating position adjustments, and a control unit for final trigger position determination. This segmentation allows each module to specialize in a specific task, improving overall measurement precision while managing system complexity through modular design
Solution Approach 2:
The compensation unit acts as an intermediary between the sensing units and the control unit. It receives sensing signals, processes them to generate compensation signals that adjust for user posture and position variations, and provides these adjustments to the control unit. This intermediary layer enables accurate touch determination across different user scenarios without requiring the control unit to directly handle all sensing complexity
