Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional illuminated pictures with neon tubes or LEDs are used, then lighting function is achieved, but weight and installation difficulty increase
Solution Approach 1:
The patent combines lighting and heating functions into a single surface element with integrated layers. The lighting layer with luminescent material and electrode layers is merged with a heating layer, allowing both functions to be achieved in one lightweight component rather than separate heavy installations.
Solution Approach 2:
The surface element is designed to perform multiple functions simultaneously - lighting, heating, and potential advertising display - within a single thin structure. This multi-functionality eliminates the need for separate neon tubes or LED installations, reducing overall weight and installation complexity.
2Illumination intensity
If traditional illuminated pictures with neon tubes or LEDs are used, then lighting function is achieved, but installation complexity increases
Solution Approach 1:
Multiple functional layers (lighting layer, heating layer, insulating layer) are combined into a single integrated surface element that can be applied as one unit, eliminating the need for separate installation of neon tubes, wiring, and heating elements.
Solution Approach 2:
The surface element can be produced with printed patterns or inscriptions that directly display advertising messages, eliminating the need for separate signage installations or complex digital screen setups.
3Adaptability or versatility
If flat screens are used for advertising, then interchangeable advertising messages are achieved, but space requirements and setup complexity increase
Solution Approach 1:
The surface element is designed as a thin, flexible structure that can be applied to various surfaces without requiring the space and infrastructure of flat screens. The element can display advertising messages directly through printed patterns or illuminated text.
Solution Approach 2:
The advertising functionality is transitioned from a two-dimensional flat screen requiring mounting space to a thin surface element that can be applied conformally to various surfaces, effectively utilizing the surface dimension rather than requiring volumetric space.
4Illumination intensity
If standard solar cells with LEDs are used, then lighting function is achieved, but cost and thickness increase
Solution Approach 1:
The surface element uses thin-film layers including a lighting layer with luminescent material and electrode layers, achieving illumination in a thickness of less than 1 mm, much thinner than standard solar cell assemblies with LEDs.
Solution Approach 2:
The element uses composite layering with thin functional layers (luminescent layer, dielectric layer, heating layer) that achieve multiple functions in a thin profile, avoiding the bulkier construction of standard solar cell assemblies.
