Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light-emitting display is implemented on a curved surface in a vehicle with complex interior design, then display information can be shown, but implementation becomes difficult and device complexity increases
Solution Approach 1:
The patent uses a projector to create an optical copy of display content and projects it onto a screen positioned on curved surfaces. This avoids the complexity of implementing light-emitting displays directly on curved surfaces while achieving the same visual output effect. The projector generates images that are projected through lenses onto the screen, replicating the display function without requiring curved surface-specific display technology.
Solution Approach 2:
The patent introduces a screen as an intermediary element between the projector and the curved surface. The screen is positioned to conform to curved surfaces and receives projected light, acting as a mediator that enables display on curved geometries without requiring the projector itself to adapt to the curvature. This intermediary approach simplifies the overall system by keeping the projector and lenses in fixed positions while the screen adapts to various surface shapes.
2Volume of moving object
If a screen is positioned closer to the projector for compact design, then device space is reduced, but light boundary heterogeneity increases and image clarity deteriorates
Solution Approach 1:
The patent applies different optical properties to different parts of the lens system. The first lens has a different focal length than the second lens, creating local quality variations that optimize image projection at different stages. Additionally, the gradation pattern is applied only to specific regions of the second lens (the light boundary region) rather than the entire lens, allowing localized control of light distribution to maintain image clarity even when the screen is positioned closer to the projector.
Solution Approach 2:
The patent changes optical parameters of the lens system by using lenses with different focal lengths and applying gradation patterns with varying optical densities. The gradation pattern modifies the refractive properties of the light boundary region, effectively changing how light is distributed. This parameter adjustment allows the system to maintain image quality at reduced distances by compensating for increased light boundary heterogeneity through controlled optical parameter variations.
3Ease of operation
If the cockpit layout is customized for different display types, then user convenience is enhanced, but system complexity increases
Solution Approach 1:
The patent creates a universal cockpit display system where the same projector and lens components can serve multiple display functions. By adjusting the position of the screen and modifying gradation patterns, the system can adapt to different display types and layouts without requiring separate hardware for each configuration. The housing can be positioned at different locations, and the screen can be adjusted to various positions, allowing one set of core components to fulfill multiple cockpit display needs.
Solution Approach 2:
The patent introduces dynamic adjustability to the cockpit display system through movable components. The housing can be positioned at different locations, and the screen position can be adjusted relative to the projector and lenses. This dynamic capability allows the system to adapt to different display requirements and layouts without being fixed in a single configuration, enabling customization while using the same base hardware platform.
