Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat cables used for power supplying or signal transferring are not illuminable, and additional illumination lines are required to make them illuminable, which limits their illumination and application due to decreasing light intensity with increasing length and limited light types.
Innovation Solution
An illumination flat cable device with a light-transmissive frame, a reflective cover, an illumination strip, and a flat cable, where the illumination strip is placed within an illumination channel and the reflective cover reflects light onto the conductive wires, providing uniform illumination along the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light guide strip with light emitting diode components is used to illuminate the flat cable, then the flat cable becomes illuminable, but the illumination intensity decreases as the length of the illuminable line increases
Solution Approach 1:
The patent divides the illumination function into multiple independent light emitting diode components distributed along the flat cable, with each component illuminating a specific section. This segmentation allows each light source to maintain optimal illumination intensity for its local area, preventing the overall illumination from decreasing with cable length.
Solution Approach 2:
The patent transitions from linear illumination (light guide strip at one end) to distributed two-dimensional illumination by placing multiple light emitting diode components at different positions along the cable, ensuring uniform illumination intensity across the entire length regardless of cable extension.
2Adaptability or versatility
If a light guide strip with light emitting diode components is used to illuminate the flat cable, then the flat cable becomes illuminable, but the light types are limited by the connected light emitting diode components
Solution Approach 1:
The patent incorporates multiple light emitting diode components with different light types (various colors and functions) into the flat cable system, allowing a single device to provide diverse illumination types for different application scenarios, enhancing versatility without requiring separate illumination systems.
Solution Approach 2:
The patent combines multiple light emitting diode components with different light characteristics into one integrated flat cable illumination system, merging their functions to achieve multi-type illumination capability while maintaining a unified structural design.
3Illumination intensity
If an additional illumination line is arranged to make the flat cable illuminable, then the flat cable becomes illuminable, but the structure becomes more complex
Solution Approach 1:
The patent merges the illumination function directly into the flat cable structure by integrating light emitting diode components and light guiding structures within the cable itself, eliminating the need for separate external illumination lines and reducing overall structural complexity.
Solution Approach 2:
The flat cable is designed to simultaneously perform power/signal transmission and illumination functions through integrated components, making the cable a multi-functional device that eliminates the need for additional dedicated illumination lines.
