Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional lamp sheets are used to provide illumination, then light emission is achieved, but light distribution is non-uniform and transparency is lost
Solution Approach 1:
The lamp sheet surface is segmented into multiple discrete reflective points rather than a continuous reflective surface. These reflective points are distributed across the transparent substrate in a pattern that segments the light reflection process, creating uniform light distribution while preserving the underlying transparency of the substrate material.
Solution Approach 2:
The reflective properties are localized to specific points on the lamp sheet surface rather than being uniformly distributed. Each reflective point has specific optical properties tailored to redirect light in particular directions, creating local quality variations that collectively achieve uniform overall illumination while maintaining global transparency.
2Illumination intensity
If reflective surfaces are added to improve light distribution, then illumination uniformity improves, but device complexity increases
Solution Approach 1:
The reflective function is extracted from a complex continuous reflective surface and condensed into discrete reflective points. This extraction simplifies the overall structure by removing the need for large-area reflective coatings or complex optical components, achieving the same light distribution function with minimal structural elements.
Solution Approach 2:
The lamp sheet employs a composite structure combining a transparent substrate material with discrete reflective point elements. This composite approach integrates the transparency function of the substrate with the light redistribution function of the reflective points, achieving multiple functions simultaneously without requiring separate complex components.
3Ease of operation
If the lamp sheet body is made transparent for visibility, then external visibility improves, but light emission capability deteriorates
Solution Approach 1:
The reflective points act as intermediary elements between the light source and the external environment. They mediate the light emission process by capturing light from the source and redistributing it uniformly across the transparent substrate, enabling the lamp sheet to simultaneously maintain transparency for visibility and provide effective illumination through the reflective point network.

AI summary
A lamp sheet includes a transparent flake-like lamp sheet body. A power supply end, electrically connected to the lamp sheet body through a lead wire. The power supply end is configured to supply power to the lamp sheet body. A surface of the lamp sheet body is provided with neatly arranged and distributed reflective points. An area of the reflective points gradually increases along one end of the lamp sheet body away from the lead wire. The lamp sheet can be made transparent, so that it is convenient for a user to see an external environment clearly through the lamp sheet when the lamp sheet is applied to a mask. Furthermore, the reflective points are configured, which can enable the lamp sheet to emit light uniformly. Moreover, there are various plans for the power supply end, which brings various power supply ways for the lamp sheet.
