Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicular display devices are fixedly disposed in front of driver seat and passenger seat, then the device structure is simple and easy to manufacture, but the cockpit space freedom is restricted and service flexibility is limited
Solution Approach 1:
The patent implements a movable display device that can slide along the dashboard from the center toward driver or passenger sides. The display unit is mounted on a movable platform with driving mechanisms (motors, rails, or belts) that enable dynamic repositioning. This dynamic structure allows the display to adapt to different usage scenarios (driver mode, passenger mode, or shared mode) while maintaining a relatively compact base structure, thus achieving service flexibility without excessive complexity increase.
Solution Approach 2:
The display device is designed to serve multiple functions and multiple users. By enabling the display to move between driver and passenger sides, a single device can function as both driver's display and passenger's display, eliminating the need for separate fixed displays for each position. The system can adapt its position based on who needs information, making the device universal rather than position-specific.
2Ease of operation
If vehicular display devices are fixedly disposed, then the device complexity is low, but the operation convenience and intuitiveness are insufficient
Solution Approach 1:
The display device incorporates movable components including sliding mechanisms, rotating joints, or articulated arms that allow the display to dynamically adjust its position and orientation. Motors, sensors, and control systems are integrated to enable smooth movement and precise positioning, enhancing operability through motion while managing complexity through systematic integration of these dynamic elements.
Solution Approach 2:
The system includes sensors (position sensors, proximity sensors, or user input detectors) that provide feedback about the display's current state and user interactions. This feedback loop allows the control system to adjust the display position automatically or respond to user commands, improving operation convenience through intelligent control while the feedback mechanisms themselves add measurable but manageable complexity.
3Productivity
If a sliding knob with guide rails and location sensors is integrated, then the operation intuitiveness is improved and menu selection efficiency is enhanced, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical button presses or touchscreen taps with a sliding knob mechanism guided by guide rails. The knob's linear or rotational movement along the rail directly corresponds to menu navigation, converting complex multi-step touchscreen operations into simple physical sliding actions. This mechanical substitution improves selection efficiency while the guide rail structure provides a compact, integrated solution that manages the added complexity.
Solution Approach 2:
The guide rail acts as an intermediary between the user's manual input and the display's menu selection system. The rail translates arbitrary sliding motions into precise, discrete position changes that correspond to specific menu options. Location sensors detect the knob's position along the rail and convert it into digital signals for menu navigation, serving as an intermediary that simplifies the interaction while managing the complexity of precise positioning and detection.
