Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of functions controlled through the smart key increases, then the versatility of the smart key is improved, but the number of key buttons increases leading to increased device complexity
Solution Approach 1:
The patent transitions from a two-dimensional array of physical buttons to a multi-dimensional display interface that can present multiple functions and control options on a single surface. The display shows various control functions (air conditioning, audio, navigation, etc.) and their parameters in different layers, allowing users to access numerous functions without adding physical buttons.
Solution Approach 2:
The smart key is designed to perform multiple functions through a single display interface rather than dedicated buttons for each function. The display can dynamically adapt to show different control functions based on vehicle state and user needs, making the smart key a universal control device for various vehicle systems including climate control, audio, navigation, and vehicle settings.
2Adaptability or versatility
If the smart key is used for various functions outside the vehicle, then the versatility is improved, but the capability for in-vehicle control remains limited
Solution Approach 1:
The smart key's display interface dynamically adapts its content and functionality based on the vehicle's operational state. When the vehicle is running, the display shows and enables control of running functions. When parked, it shows parking-related functions. This dynamic adaptation allows the smart key to provide comprehensive in-vehicle control capabilities matched to the current context.
Solution Approach 2:
The system implements feedback mechanisms where the display shows the current vehicle state and responds to user operations in real-time. The display updates to reflect operation results, providing visual feedback that confirms control actions. This feedback loop enhances the user experience by making the smart key responsive and intuitive for in-vehicle control.
