Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical buttons and direction indicators are used for viewing-angle switching, then the system structure is simple and reliable, but the system cannot provide diverse and detailed viewing-angle pictures
Solution Approach 1:
The touch panel serves multiple functions: it displays vehicular images and simultaneously acts as a control interface for viewing-angle switching. By integrating the display and control functions into a single component, the system achieves diverse viewing angles without adding complex separate control mechanisms.
Solution Approach 2:
The patent replaces physical buttons and mechanical direction indicators with a touch-based electronic control system. This substitution enables more diverse viewing-angle control through software processing of touch positions, eliminating the limitations of mechanical control interfaces while maintaining system reliability.
2Ease of operation
If physical buttons are used for view switching, then the operation is straightforward, but the user cannot perform convenient and intuitive operations for adjusting display parameters
Solution Approach 1:
The touch panel integrates multiple control functions including viewing-angle switching, zoom level adjustment, and pan/tilt control within a single interface. Users can perform diverse operations by touching different positions and using different gestures, providing both convenience and flexibility without requiring multiple separate controls.
Solution Approach 2:
The touch panel acts as an intermediary between the user and the image processing system. Touch position information serves as a mediator that translates user intent into specific control parameters for image synthesis and display adjustment, enabling intuitive and flexible control.
3Loss of information
If only four fixed viewing angles are provided, then the system is simple to implement, but it cannot provide complete surrounding traffic information
Solution Approach 1:
The system transitions from static fixed viewing angles to dynamic continuous viewing angles. By calculating synthesis parameters based on touch position coordinates, the system can generate any viewing angle within the surrounding environment, providing complete traffic information while using efficient real-time parameter adjustment rather than pre-defined fixed views.
Solution Approach 2:
The patent changes the control parameter from discrete fixed angle selections to continuous touch position-based parameters. The processing unit calculates synthesis parameters dynamically based on the touch coordinates, enabling seamless transition between any viewing angles and comprehensive coverage of surrounding traffic conditions.

AI summary
A method for controlling a display of a vehicular image by a touch panel is provided. The vehicular image is synthesized by a plurality of sub-images. The method includes the following steps: detecting a first touch event on the touch panel to generate touch position information; determining a control parameter according to the touch position information; and switching a viewing-angle stage of the vehicular image according to the control parameter.
