Operation Button Tubular Body Flange Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation buttons face challenges in preventing light leakage and ensuring handleability during assembly, particularly with precision-requiring parts that can be deformed or contaminated, affecting proper operation.
Innovation Solution
The design includes a tubular body with a light-transmitting top and circumferentially arranged legs, supported by a flange that separates the assembly components, allowing for precise handling and reducing light leakage by directing stray light away from critical areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple components are used to compose the operation button, then light leakage can be prevented, but handleability during assembly deteriorates due to deformation and contamination of precision parts
Solution Approach 1:
The operation button is divided into multiple components: a body, a top with light-transmitting portion, legs, and a flange. This segmentation allows light leakage to be prevented through proper component design while the flange protects precision parts during assembly.
Solution Approach 2:
The flange acts as an intermediary protective element between the light-shielding structure and the precision-requiring parts. It prevents deformation and contamination of critical components during assembly while maintaining the light leakage prevention function.
2Object-affected harmful factors
If precision-requiring parts are used in the operation button, then light leakage prevention is improved, but manufacturing precision deteriorates due to deformation and contamination during assembly
Solution Approach 1:
The flange is designed to protect precision-requiring parts before assembly operations are completed. By positioning the flange to cover and shield critical components during the assembly process, deformation and contamination are prevented in advance.
Solution Approach 2:
The flange serves as a protective intermediary that isolates precision parts from harmful effects during assembly, ensuring manufacturing precision is maintained while still allowing light leakage prevention functionality.
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 configuration enhances handleability during assembly by preventing deformation and contamination of precision parts and effectively suppresses light leakage, ensuring reliable operation button functionality.
Implementation Method 1
light from a light source is guided through a light guide plate in the shape of a thick-walled flat plate to the inner-surface side of the key top
Implementation Method 2
a light-shielding layer that covers the illuminated key-side surface of the light guide plate over the area other than the part facing the illuminated key. This helps effectively prevent light leakage

AI summary
An operation button includes: a body that is in a tubular shape; a top which has a light-transmitting portion and which is attached to the body at its one end; a plurality of legs that are provided at the other end of the body at intervals from each other in the circumferential direction; and a flange arranged between the one end and the other end of the body.
