Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional light emitting devices are used, then illumination function is provided, but flexibility and adaptability to different contours is limited
Solution Approach 1:
The patent applies this principle by using a flexible printed circuit board as the substrate for mounting LED modules. This flexible circuit board can be bent and shaped to adapt to different contours and geometries of interior surfaces, while maintaining electrical connectivity. The thin-film nature of the circuit board allows it to conform to complex shapes without requiring rigid structural modifications.
Solution Approach 2:
The patent implements dynamics by designing a modular LED system where individual LED modules can be selectively activated or deactivated. This allows the illumination pattern to be dynamically adjusted to match different contours and lighting requirements. The system can adapt its light emission pattern in real-time based on the specific application needs.
2Reliability
If light emitting devices are made space-saving and contour-adapted, then illumination efficiency is improved, but resistance to external influences like mechanical loads, dirt, and moisture is reduced
Solution Approach 1:
The patent applies composite materials by combining LED modules with a flexible circuit board substrate that can be coated with protective layers. The composite structure integrates the lighting function with the protective enclosure, providing resistance to mechanical loads, dirt, and moisture while maintaining a compact form factor. The circuit board can be sealed or coated to enhance environmental resistance.
Solution Approach 2:
The flexible circuit board acts as both the structural support and the protective shell for the LED modules. Its thin-film nature allows it to provide protection against external influences while minimizing the overall device volume. The flexible shell can be designed to seal the LED modules against moisture and dirt.
3Illumination intensity
If conventional light emitting devices are used, then illumination is provided, but aesthetic appeal and orientation assistance are limited
Solution Approach 1:
The patent utilizes color changes by employing LEDs capable of emitting different colors or by using phosphor converts to transform the light wavelength. This allows the system to provide aesthetically pleasing illumination with varying color temperatures and hues. The ability to change color also assists orientation by providing visual cues for different zones or functions within a space.
Solution Approach 2:
The dynamic control of LED modules allows for adjustable illumination patterns and intensities that can enhance aesthetic appeal. The system can be programmed to provide orientation assistance through strategic lighting patterns that guide users through spaces or highlight important areas.
4Adaptability or versatility
If light emitting devices are customized for different applications, then specific illumination needs are met, but production cost and manufacturing complexity increase
Solution Approach 1:
The patent applies segmentation by dividing the lighting system into modular LED units that can be independently manufactured and then assembled in different configurations. This standardization of modules allows for efficient industrial production of individual components, while the modular nature enables customization for different applications by simply rearranging or selecting different module combinations.
Solution Approach 2:
The patent implements universality by designing LED modules with standardized mounting interfaces and electrical connections that can be used across multiple applications. The flexible circuit board substrate serves multiple functions as both structural support, electrical conduit, and protective element. This multi-functionality reduces the number of different components needed, simplifying manufacturing while maintaining adaptability.

AI summary
A light emitting device includes a radiation source for the emission of electromagnetic radiation and a converter element on which the electromagnetic radiation impinges in a first surface region and which, excited by the impinged electromagnetic radiation, emits visible light into an environment in a second surface region which differs at least partially from the first surface region. The wavelength of the light emitted into the environment differs from the wavelength of the electromagnetic radiation impinged on the converter element. The converter element includes a luminous element including a textile with a converter material. The converter material due to excitation by the electromagnetic radiation with a first wavelength emits visible light with a second wavelength differing from the first wavelength. The radiation source realizes a background illumination for the converter element. The first surface region is formed by a side surface or a back surface of the converter element.
