Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If LED strips are designed for direct light emission, then the light emission is directional and easy to place, but the light distribution is uneven and can create discomfort or blinding effect
Solution Approach 1:
The patent inverts the traditional direct emission approach by directing LED light towards the reflective interior surface of the loop, where it reflects and exits through the opening. This inversion transforms direct directional emission into indirect diffuse emission, eliminating discomfort and blinding effects while maintaining ease of placement.
Solution Approach 2:
The reflective interior surface acts as an intermediary between the LED light source and the final light output. By introducing this reflective mediator, the light is redirected and diffused before reaching the environment, solving the problem of uneven distribution and discomfort while preserving the simple LED strip structure.
2Object-affected harmful factors
If LED strips are arranged in a profile or luminaire for indirect light emission, then indirect light emission is achieved, but the products are costly and cumbersome
Solution Approach 1:
The patent merges the LED strip with a simple loop structure, combining the light source and the light-distributing form factor into a single integrated component. This eliminates the need for separate profiles or luminaires, reducing complexity and cost while achieving indirect light emission.
Solution Approach 2:
The LED strip is formed into flexible loops that can be easily shaped and attached to surfaces. This flexible loop design replaces cumbersome rigid profiles and luminaires, maintaining indirect light emission functionality while dramatically simplifying the structure and reducing costs.
3Object-affected harmful factors
If LED strips are arranged in a profile or luminaire for indirect light emission, then indirect light emission is achieved, but customization is difficult to realize
Solution Approach 1:
The LED strip loops are designed to be flexible and adaptable, allowing users to customize the shape, size, and placement of loops to suit different applications and environments. This dynamic flexibility enables easy customization while maintaining the indirect light emission function, unlike rigid profile-based solutions.
4Adaptability or versatility
If LED strips are made compact and adaptable, then they are discrete and practical, but existing indirect light emission solutions lose these features
Solution Approach 1:
The LED strip is nested into a loop configuration, where the strip itself forms the loop structure. This nesting allows the compact and adaptable LED strip to achieve indirect light emission without requiring additional external structures, preserving its discrete and practical features while adding the indirect emission capability.
