Button Light Guide Uniform Illumination via Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional button structures with light transmittance suffer from non-uniform light projection due to the placement of light guiding components on the lateral side of the pressing portion, resulting in shadowing and inadequate aesthetic display of operating states.
Innovation Solution
A button structure design featuring a light guiding component with one end above the light source and the other end inside an accommodating space, allowing light to project uniformly onto the bottom of the pressing portion, preventing shadowing and enhancing light transmittance and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light guiding component is disposed on a lateral side of the rod connected with the pressing portion, then the button structure can be assembled, but the light guiding component cannot guide light uniformly onto the pressing portion, resulting in shadowing
Solution Approach 1:
The light guiding component transitions from a lateral side disposition to a bottom-side disposition relative to the pressing portion. By placing the light guiding component on the bottom surface of the pressing portion rather than on the lateral side, light can be guided uniformly through the pressing portion without shadowing, while the accommodating portion provides vertical clearance to maintain this optimized spatial arrangement.
2Illumination intensity
If the light guiding component is disposed right beneath the pressing portion, then uniform light projection can be achieved, but the light guiding component may contact the pressing portion when pressed
Solution Approach 1:
The light guiding component is nested within the accommodating space formed by the accommodating portion. The accommodating portion creates a recess that houses the light guiding component, providing vertical clearance between the light guiding component and the pressing portion. This nested arrangement allows the light guiding component to be positioned directly beneath the pressing portion for optimal light guidance while preventing contact during button pressing operations.
3Reliability
If the light guiding component is positioned to avoid contact with the pressing portion, then reliability is maintained, but light projection uniformity may be compromised
Solution Approach 1:
The accommodating portion acts as an intermediary structure between the light guiding component and the pressing portion. It provides the necessary vertical clearance to prevent contact while maintaining the optimal positioning of the light guiding component directly beneath the pressing portion. The accommodating space serves as a mediator that reconciles the conflicting requirements of contact avoidance and light projection uniformity.
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
The solution ensures uniform light projection onto the pressing portion, improving the visual representation of operating states and enhancing the aesthetic appeal by eliminating shadows, thus addressing the issue of non-uniform light transmittance in conventional designs.
Implementation Method 1
a light guiding component, an end of the light guiding component being disposed above a light source and the other end of the light guiding component being disposed inside the accommodating space, the light guiding component being for guiding light emitted from the light source to project on a bottom of the pressing portion
Data Source
AI summary
A button structure includes a pressing portion, and an accommodating portion connected to a side of the pressing portion. An accommodating space is formed inside the accommodating portion. The button structure further includes a protruding portion connected to a side of the accommodated portion for actuating a switch when the pressing portion is pressed, and a light guiding portion. An end of the light guiding portion is disposed above a light source, and the other end of the light guiding portion is disposed inside the accommodating space. The light guiding portion is for guiding light emitted from the light source to project on a bottom of the pressing portion.
