Spliced Circuit Board Reflector Layout for Uniform Light Emission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in flexible size adjustment and uniform light emission, particularly when multiple circuit boards are spliced together, leading to potential dark streaks at gaps between boards due to inadequate light reflection.
Innovation Solution
The electronic device incorporates a circuit board with a substrate, semiconductor components, a first light reflecting structure on the surface, and a second light reflecting structure on both the surface and side surfaces, with the second structure extending into gaps between adjacent boards to ensure uniform light reflection and prevent dark streaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple circuit boards are spliced together to achieve flexible size adjustment, then the device can be scaled to different sizes, but dark streaks appear at the gaps between boards due to insufficient light reflection
Solution Approach 1:
The light reflecting structure extends from the front surface into the gap between circuit boards in the depth dimension, creating a three-dimensional configuration. This allows the structure to intercept and reflect light that would otherwise escape through the gaps, eliminating dark streaks while preserving the ability to splice multiple boards for flexible sizing.
Solution Approach 2:
The light reflecting structure is strategically positioned at the gaps between circuit boards where light reflection is most needed. By concentrating reflective material at these specific locations rather than uniformly across all surfaces, the design achieves uniform light emission while minimizing material usage and maintaining adaptability for different board configurations.
2Illumination intensity
If a light reflecting structure is added to prevent dark streaks at gaps, then uniform light emission is improved, but the device complexity increases
Solution Approach 1:
The light reflecting structure serves multiple functions simultaneously: it reflects light to eliminate dark streaks, provides structural support at the gaps between boards, and can be integrated with the existing circuit board assembly process. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The light reflecting structure is merged with the circuit board assembly, forming an integrated component rather than a separate addition. This integration allows the reflective function to be achieved while maintaining a streamlined device architecture and simplifying the overall structure.
