Curved Touch Panel Integrating Virtual Buttons to Reduce Device Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch device assembly methods fail to achieve a slim design due to the thickness requirements of function buttons on lateral sides, which impedes the development of ultrabooks and other compact electronic devices.
Innovation Solution
A touch panel with a curved surface design that integrates touch function buttons, replacing traditional lateral surfaces, combined with advanced direct bonding and hinge-up assembly methods to reduce thickness and save space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical function buttons are disposed on lateral sides of the touch panel, then the device provides tactile feedback and ease of operation, but the device thickness increases and slim design is impeded
Solution Approach 1:
The patent uses visual representations (images or icons) of function buttons on the touch panel surface to replicate the appearance and functionality of physical buttons, eliminating the need for actual protruding button structures while maintaining user interface functionality
Solution Approach 2:
The patent transitions from three-dimensional physical buttons to two-dimensional visual representations on the touch panel surface, reducing the thickness requirement while preserving button functionality through touch-sensitive visual elements
2Area of stationary object
If conventional assembly methods with reserved spaces are used for touch panel components, then the device provides adequate space for all parts, but the overall device thickness becomes larger than expected
Solution Approach 1:
The patent integrates the back cover and panel frame functions into a single unified structure, eliminating the need for separate components and their associated reserved spaces, thereby reducing overall device thickness while maintaining structural integrity
Solution Approach 2:
The patent designs the back cover to serve multiple functions simultaneously - providing structural support, housing for components, and aesthetic appearance - eliminating the need for separate dedicated structures for each function and reducing overall device thickness
