An electronic device design incorporating a housing with specific through holes and a light guiding structure comprising a light guiding layer, diffusion layer, and light adjusting layer, where a single light source is used to emit light through multiple holes via a light transmitting portion, with the diffusion layer homogenizing and the light adjusting layer optimizing light flux, reducing the need for multiple light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the density and quantity of light emitting holes are increased to improve light effects, then the quality of light effects is improved, but the quantity of light sources needs to be increased accordingly, leading to increased costs and overheating
Solution Approach 1:
The light guiding layer is segmented into light transmitting portions and light shielding portions, allowing a single light source to illuminate multiple light emitting holes through selective light transmission paths. This segmentation enables one light source to serve multiple holes without requiring additional light sources for each hole.
Solution Approach 2:
The light guiding structure acts as an intermediary between the single light source and multiple light emitting holes. It redirects and distributes light from one source to multiple holes through its light transmitting and shielding portions, eliminating the need for multiple light sources.
2Illumination intensity
If the quantity of light sources is increased to improve light distribution density, then the light effects quality is improved, but the costs of the electronic device are increased
Solution Approach 1:
The light guiding structure provides multi-functionality by enabling a single light source to illuminate multiple light emitting holes simultaneously. This universal design allows one light source to perform the function that would otherwise require multiple light sources, reducing device costs.
Solution Approach 2:
The light guiding structure creates optical copies or redirects of light from a single source to multiple holes. Instead of using multiple physical light sources, the system uses optical copying through the light guiding layer to distribute light across multiple emitting holes.
3Illumination intensity
If the quantity of light sources is increased to improve light distribution density, then the light effects quality is improved, but overheating in the electronic device is caused
Solution Approach 1:
The design extracts the light distribution function from multiple light sources and consolidates it into a single light source combined with a light guiding structure. This extraction removes the heat-generating components (additional light sources) while maintaining the light distribution function through optical guidance.
Solution Approach 2:
The light guiding structure converts the limitation of using fewer light sources (potentially lower light distribution) into a benefit by using optical redirection and diffusion. The light shielding and transmitting portions work together to distribute light effectively from one source, turning what could be a disadvantage into an advantage by reducing heat generation.

Function Achieved in This Case
This design effectively reduces the number of light sources required, enhancing light distribution and quality while minimizing overheating and costs, by utilizing a single light source to emit light through multiple holes, achieving homogenized and optimized light effects.
Implementation Method 1
Light emitted by the light source passes through the light guiding structure and the intersection, and is separately emitted through the two first through holes and the two second through holes along the light transmitting portion
Implementation Method 2
The diffusion layer is disposed at the position corresponding to the light transmitting portion
Implementation Method 3
The light adjusting layer is disposed at the position corresponding to the first section. The light adjusting layer includes a second light transmission rate, and the second light transmission rate is less than the first light transmission rate
