Integrated Touch Sheet for Mobile Terminal Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with touch screens and key input schemes face complexity in user interfaces, where the key input scheme can make the interface appear too complicated, and existing solutions fail to seamlessly integrate both input methods for improved usability and aesthetics.
Innovation Solution
A mobile terminal design featuring a touch sheet with both touch screen and touch button patterns integrated onto a single transmissive insulation layer, eliminating the need for separate touch sensing units and enhancing manufacturing efficiency, while a conductive shielding line and illumination unit improve the user interface and external appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch screen and key input scheme are combined, then both advantages of touch screen and key input are supported, but the user interface appears too complicated
Solution Approach 1:
The patent combines the touch screen pattern portion and touch button pattern portion into a single integrated touch sheet, merging two separate input interfaces into one unified structure. This integration maintains both touch screen and key input functionalities while presenting a unified, less complicated user interface, directly resolving the contradiction between input versatility and interface complexity
Solution Approach 2:
The integrated touch sheet serves multiple functions simultaneously - it acts as both a touch screen for graphical input and a touch button interface for key-based input. This multi-functional design allows the single component to replace what would traditionally require separate touch sensing units, reducing overall system complexity while maintaining input versatility
2Adaptability or versatility
If separate touch sensing units are used for first and second regions, then each region can be independently optimized, but manufacturing and assembling procedures become more complex
Solution Approach 1:
The patent merges the touch sensing functionality for both the first region (touch screen) and second region (touch buttons) into a single integrated touch sheet. This eliminates the need for separate touch sensing units, thereby simplifying manufacturing and assembly procedures while still allowing each region to maintain its specific functional characteristics through distinct pattern designs
3Shape
If a window is provided to cover the touch sheet, then assembly gaps and border lines are reduced, but the structure becomes more complex
Solution Approach 1:
The patent extracts the aesthetic improvement function (reducing assembly gaps and border lines) into a separate window component that covers the touch sheet. This allows the window to serve as a cosmetic element that hides the integrated touch sheet's seams and borders, improving external appearance without fundamentally altering the core integrated structure of the touch sheet itself

Function Achieved in This Case
The solution provides a more user-friendly interface by integrating touch screen and key input functionalities, reducing assembly gaps and border lines, and enhancing usability with tactile inputs, thus improving the external appearance and user experience.
Implementation Method 1
a touch sheet that senses user contact applied on the first and second regions
Implementation Method 2
a conductive shielding line for shielding the data lines of the touch screen pattern portion
Implementation Method 3
an illumination unit that illuminates the touch button pattern portion
Data Source
AI summary
A mobile terminal having an input device that performs inputting in a tactile manner is disclosed. A touch screen of a first region and touch buttons of a second region are implemented by a single touch sheet without having touch sensing units. Thus, manufacturing, assembling and handling can be facilitated.
