Detachable Light Guide Bar for Mainboard Edge Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light emitting modules for computer hosts often occupy interior space, requiring modifications to the computer case and limiting the ability to change light effects and colors based on user preferences.
Innovation Solution
A detachable light emitting module comprising a circuit board with light emitting elements and a light guide bar, which is mounted to the mainboard's side edge, using a metal guard plate for protection and alignment, allowing for uniform light distribution without occupying additional space within the computer case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light emitting module is installed inside the computer case, then light effects are provided, but the interior space of the computer case is occupied
Solution Approach 1:
The light emitting module is extracted from the interior space of the computer case and repositioned to the exterior, specifically attached to the side edge of the mainboard. This allows the light effects to be provided while the interior space remains unoccupied for mounting essential components.
Solution Approach 2:
The light emitting module is moved from the vertical interior space dimension to the lateral exterior dimension, attached to the side edge of the mainboard. This dimensional shift eliminates space occupation within the computer case while maintaining light effect functionality.
2Illumination intensity
If the computer case size is changed to accommodate light emitting modules, then light effects can be displayed, but the original dimensions and configuration are altered
Solution Approach 1:
The light emitting module is extracted from the computer case interior and repositioned externally to the mainboard side edge, eliminating the need to modify computer case dimensions while still providing light effects.
3Illumination intensity
If light emitting elements are directly mounted on the mainboard, then light effects are provided, but the light distribution is not uniform
Solution Approach 1:
A light guide bar is introduced as an intermediary component between the light emitting elements and the display surface. The light guide bar receives light from the light emitting elements and distributes it uniformly along its length, achieving even light distribution for the light effects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides diverse light color patterns and effects without altering the computer case's size, allowing for user-adjustable light displays while maintaining the host's regular dimensions and configuration.
Implementation Method 1
The light guide bar is disposed at the circuit board, when the light emitting module is assembled to the mainboard, the light guide bar uniformly guides light from the light emitting elements
