Segmented Touch Detecting Face for Tap and Slide Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch detection systems in electronic equipment face challenges in achieving optimal operability for tap and slide operations due to the size of touch detection electrodes, where larger electrodes improve tap and slide operability but increase camera size, and smaller electrodes enhance camera size reduction but deteriorate tap and slide operability, leading to issues with distinguishing between tap and full-area pressing operations.
Innovation Solution
The electronic equipment incorporates a touch detecting unit with a divided touch detecting face, where the relation of 1.4≤W1/W2≤6.0 is satisfied, allowing for distinct execution of functions based on the area touched, with W1 representing the length of the touch detecting face in the direction of slide operation and W2 representing the length of the second touch detecting face, enabling precise differentiation between tap, slide, and full-area pressing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrode size for touch detection is made larger, then operability for tap operations and slide operations increases, but the size of the camera increases
Solution Approach 1:
The touch detecting face is divided into multiple regions (first touch detecting face, second touch detecting face, third touch detecting face) with different sizes. The first and third faces have larger areas to facilitate easy tap and slide operations, while the middle second face has a smaller area. This segmentation allows different regions to serve different operational purposes, resolving the contradiction between overall operability and compact size.
Solution Approach 2:
Different regions of the touch detecting face are assigned different functional qualities. The first and third touch detecting faces are optimized for tap and slide operations with larger areas, while the second touch detecting face is optimized for full-area pressing detection with a smaller area. This local differentiation allows each region to excel at its specific function without compromising the overall system size.
2Volume of moving object
If the electrode size is made smaller, then the size of the camera is reduced and full-area pressing operability improves, but operability for tap operations and slide operations deteriorates
Solution Approach 1:
The touch detecting face is segmented into multiple regions with different size characteristics. The first and third faces provide larger contact areas for comfortable tap and slide operations, while the second face provides a smaller area that enables reliable full-area pressing detection. This segmentation resolves the contradiction by distributing different size requirements to different regions.
Solution Approach 2:
Each region of the touch detecting face is given local quality appropriate for its function. The first and third regions have larger areas optimized for tap and slide operations, while the second region has a smaller area optimized for full-area pressing. This local optimization allows the system to achieve both large and small electrode benefits in different locations.
3Ease of operation
If the electrode size is optimized for tap operations, then tap operability improves, but the ability to distinguish between tap and full-area pressing operations deteriorates
Solution Approach 1:
The touch detecting face is divided into multiple regions that can be independently detected. When a user performs a tap or full-area press, the system can detect which specific regions are activated. This segmentation allows the system to distinguish between tap operations (affecting first or third faces) and full-area pressing (affecting all faces including the middle second face), resolving the contradiction between operability and detection precision.
Solution Approach 2:
The system provides feedback by analyzing the pattern of activated regions. By detecting which combination of first, second, and third touch detecting faces are activated, the system can determine whether a tap or full-area pressing operation was performed. This feedback mechanism enables accurate distinction between different operation types while maintaining good operability.

AI summary
Electronic equipment includes a first operating member having a detecting unit to detect touch and slide operations. Where a detecting unit touch detecting face is touched in the touch operation over a first and a second predetermined area, larger than the first predetermined area, or less, a first function is executed. Where the touch detecting face of the detecting unit is touched in the touch operation over more than the second predetermined area, a second function is executed. The touch detecting face is divided into a first, a second, and a third touch detecting face, in that order in a direction of the slide operation. A relation of 1.4≤W1/W2≤6.0 is satisfied. W1 represents a length of the touch detecting face in the direction of the slide operation, and W2 represents a length of the second touch detecting face in the direction of the slide operation.
