Assistive Touch Button Structure for Protective Case Capture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The capture button on electronic devices, such as smartphones and tablets, is not functional when used with traditional protective cases due to the lack of assistive touch members, leading to inconvenience for users.
Innovation Solution
An assistive touch button with an insulation button block and conductive columns is designed to be mounted on the rim of the device, allowing charges from the capture button's touch surface to be transferred to the button block, enabling normal operation of the capture button even when a protective case is used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a protective case is added to protect the electronic device, then the device protection is improved, but the capture button becomes inaccessible and cannot be used normally
Solution Approach 1:
The patent introduces an assistive touch button as an intermediary component between the user and the capture button. This assistive button transfers touch forces to the capture button through a transmission mechanism, allowing users to operate the capture button functionality without directly touching the device rim, thus resolving the contradiction between device protection and button accessibility.
2Device complexity
If the capture button is embedded in the device rim, then the device structure is simplified, but the capture button cannot be extended for use with protective cases
Solution Approach 1:
The patent segments the capture button functionality into two parts: the original capture button embedded in the device rim, and an external assistive touch button mounted on the protective case. This segmentation allows the capture button to remain embedded in the device (maintaining structural simplicity) while extending its usability through the external assistive button on the protective case.
3Ease of operation
If users directly touch the device rim to operate the capture button, then the operation is simple, but the device rim is exposed to damage and contamination
Solution Approach 1:
The assistive touch button serves as a mediator that allows users to operate the capture button without directly touching the device rim. The transmission mechanism transfers the touch forces from the assistive button to the capture button, maintaining operational simplicity while protecting the device rim from damage and contamination.
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 assistive touch button forms independent charge transfer channels, allowing users to interact with the capture button's functions like focusing, shutter press, and zooming without directly touching the device rim, enhancing user experience and functionality.
