Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid electroluminescent panel structure is used, then manufacturing and assembly are simplified, but the panel cannot conform to non-flat surfaces
Solution Approach 1:
The patent applies a flexible substrate instead of a rigid panel structure, allowing the electroluminescent device to conform to non-flat surfaces while maintaining structural integrity. The flexible substrate acts as a thin film that can bend and adapt to curved surfaces without compromising the functional layers.
Solution Approach 2:
The patent employs a composite structure combining multiple materials including flexible substrate, electroluminescent phosphor layer, encapsulation layers, and adhesive layers. This composite approach enables the panel to achieve both flexibility for surface conformability and structural stability for durable assembly.
2Illumination intensity
If the electroluminescent panel is exposed to outdoor conditions, then visibility and illumination function are achieved, but ultraviolet radiation damages the fluorescent layer
Solution Approach 1:
The patent introduces an ultraviolet protection layer as an intermediary between the outdoor environment and the fluorescent layer. This layer selectively blocks harmful UV radiation while allowing visible light to pass through, thereby protecting the fluorescent layer from degradation without compromising the illumination function.
Solution Approach 2:
The patent converts the harmful effect of ultraviolet radiation into a protective function by using UV-absorbing materials in the encapsulation layers. These materials absorb the harmful UV energy and prevent it from reaching the fluorescent layer, effectively transforming a harmful environmental factor into a protective mechanism.
3Reliability
If the fluorescent layer is protected from UV radiation, then durability is improved, but light transmission may be reduced
Solution Approach 1:
The ultraviolet protection layer is designed with local quality characteristics, being selectively transparent to different wavelengths of light. It blocks harmful UV radiation (wavelengths below 400nm) while maintaining high transmission in the visible spectrum (400-700nm), thus providing protection without compromising illumination intensity.
Solution Approach 2:
The patent utilizes materials with specific optical parameters that enable selective wavelength transmission. By carefully selecting the UV protection layer material composition and thickness, the design achieves optimal balance between UV blocking capability and visible light transmission, maintaining both durability and illumination performance.
