Mobile Phone Case Sensor Button for Thick Touch-Button Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protective cases for mobile phones with touch buttons are too thick, making it difficult to operate the capacitive touch buttons conveniently.
Innovation Solution
A mobile phone protective case structure with a sensor button that senses touch and pressure, transmitting these signals to the touch button to facilitate easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective case is provided for the mobile phone, then the mobile phone is protected, but the protective case is too thick and makes the touch button deep and difficult to operate
Solution Approach 1:
A sensor button is introduced as an intermediary component between the user's finger and the touch button. The sensor button includes a sensing conductive module that detects touch input and transmits it to the touch button through the protective case structure, enabling operation without directly exposing the touch button
Solution Approach 2:
The sensor button is nested within the protective case structure, with the sensing conductive module positioned in the button positioning hole. The elastic ring provides nested elastic support between the sensor button and the protective case, allowing the sensor button to be housed within the protective case while maintaining 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
Enables convenient control of touch buttons through the sensor button, allowing for accurate transmission of touch and pressure signals to the mobile phone, enhancing user experience.
Implementation Method 1
The elastic ring has a flat outer ring edge, a flat inner ring edge, and a curved elastic section connected between the outer ring edge and the inner ring edge

AI summary
A mobile phone protective case structure includes a protective case and a sensor button. The protective case has a circumferential frame and an accommodation space within the frame for accommodating a mobile phone having at least one touch button. The protective case has a button positioning hole corresponding in position to the touch button. The sensor button is disposed in the button positioning hole, and includes an outer frame, an elastic ring, and a sensing conductive module. The outer frame has a through hole. The outer edge of the elastic ring is attached to the outer frame, and the inner edge of the elastic ring is attached to the sensing conductive module. The sensing conductive module is exposed through the through hole of the outer frame. The outer frame is secured to the protective case, and the sensing conductive module corresponds to the touch button.
