Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional flat display is used in the vehicle cockpit, then the display structure is simple and easy to manufacture, but the display cannot be flexibly adapted to curved surfaces and limited layout options reduce user convenience
Solution Approach 1:
The patent replaces traditional mechanical flat display structures with a projection-based optical system. The projector emits light that passes through a light-transmitting element and lens element to form images on curved surfaces, substituting mechanical display components with an optical projection mechanism that naturally adapts to curved geometries without requiring complex curved display panel manufacturing
Solution Approach 2:
The display system is designed to serve multiple functions: it can display information on various curved surfaces (dashboard, windshield, side panels), support different layout configurations, and provide both visual and touch interactions. The bracket structure also serves dual purposes by providing both structural support and mounting functionality for the projection system
2Adaptability or versatility
If a projector-based display system is implemented, then flexible display on curved surfaces is achieved, but the device complexity increases due to multiple components including projection lens, bezel, and bracket
Solution Approach 1:
The patent combines multiple functions into integrated components: the bracket serves both as a structural support element and a mounting mechanism for the projection system; the bezel provides both structural framing and an interface for connecting the projection lens assembly; the light-transmitting element and lens element are integrated into a unified optical path system that reduces the need for separate alignment mechanisms
Solution Approach 2:
The display system is divided into modular components (projector, light-transmitting element, lens element, bezel, bracket) that can be independently manufactured, tested, and assembled. This segmentation allows for easier maintenance and replacement of individual components while maintaining overall system flexibility
3Ease of operation
If touch film is added to enable touch functions, then user interaction capability is improved, but the manufacturing complexity and layer structure of the display increases
Solution Approach 1:
The touch film is integrated with the optical elements in a unified layered structure where the light-transmitting element, lens element, and touch film are stacked and bonded together as a single assembly. This merging eliminates the need for separate touch interface integration steps and simplifies the manufacturing process by treating the touch-capable display as one integrated component rather than multiple separate layers requiring complex alignment
