Silica Gel Touch Button Elastic Displacement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch buttons on laptop computers, which use metallic spring plates for elasticity, result in a stiffer feel and unwanted metal sound when pressed, compromising user experience.
Innovation Solution
A touch button design featuring a touch board with a press area and elastic connectors and supporters made of silica gel, providing a difference in height and elastic displacement to improve the pressing feel without metal sound, using a fixing element and elastic connectors and supporters to create an elastic supporting force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a metallic spring plate is used to achieve elastic displacement, then the touch button can return to its original position, but the pressing feel becomes stiffer and metal sound is generated
Solution Approach 1:
The patent changes the material parameter from metallic spring plate to elastic sponge material, which fundamentally alters the elastic properties. The elastic sponge provides softer elastic displacement that improves pressing feel while eliminating metal sound, directly resolving the contradiction between maintaining elastic function and improving user experience
Solution Approach 2:
The patent employs an elastic sponge as a flexible elastic element that can be compressed and returns to its original shape. This flexible material replaces the rigid metallic spring plate, providing a softer pressing sensation while maintaining the necessary elastic recovery function, thus resolving the contradiction between elastic stability and pressing comfort
2Stability of the object's composition
If a metallic spring plate is used to achieve elastic displacement, then the touch button can return to its original position, but metal sound is generated when pressed
Solution Approach 1:
The patent changes the material parameter from metallic spring plate to elastic sponge material, which fundamentally alters the elastic properties. The elastic sponge provides softer elastic displacement that improves pressing feel while eliminating metal sound, directly resolving the contradiction between maintaining elastic function and improving user experience
Solution Approach 2:
The patent converts the harmful metal sound into a beneficial silent operation by replacing the metallic spring plate with an elastic sponge. The sponge material inherently absorbs the impact sound that would otherwise be generated by metal-to-metal contact, transforming the harmful acoustic effect into a beneficial silent pressing experience
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
Enhances the pressing feel by allowing elastic vertical displacement, reducing stiffness and eliminating metal sound, thereby improving user experience.
Implementation Method 1
The elastic connector is used to connect the touch board with the fixing element, and is provided with a first connecting portion which is connected with the touch board, a second connecting portion which is connected with the fixing portion, and an elastic connecting portion which is connected between the first connecting portion and the second connecting portion to form the difference in height between the touch board and the fixing element, so that a state of elastic vertical displacement can be manifested between the press area and the casing by the elastic connecting portion
Implementation Method 2
The plural elastic supporters are disposed in the press area of the touch board, and each elastic supporter includes a positioning portion which is fixed on the touch board and an elastic portion which is extended from the positioning portion toward the casing to be disposed in the gap. An elastic supporting force is formed to the press area by the elastic portion, allowing the press area to form the state of elastic vertical displacement on the casing by the elastic supporting force

AI summary
A touch button with better feel in pressing is disposed on a casing, including a touch board having a touch area and a press area, a fixing element disposed on a side of the touch board to form a difference in height from the touch board, an elastic connector for connecting the touch board with the fixing element and forming a state of elastic vertical displacement between the press area and the casing, and plural elastic supporters forming an elastic supporting force to the press area, thereby enabling the press area to manifest the state of elastic vertical displacement on the casing by the elastic supporting force.
