Solution Overview

Problem

In electronic devices with touch sensors, the increasing size of touch-control areas near the edges can lead to mishandling due to variations in user finger size and handling habits, causing unintended inputs.

Innovation Solution

An electronic device and method that allow users to adjust the touch-control area dynamically by receiving a touch-control area adjustment command, determining a specific portion of the touch sensor to enable or disable, and displaying a tag to represent the adjusted area, thereby preventing unintended inputs outside the adjusted area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the touch sensor area is increased to provide a larger display region, then the display area is improved, but the risk of mishandling increases due to fingers contacting the touch sensor near the edges

Engineering Contradiction:
Improvetouch sensor areaVSAvoidmishandling risk
Core Design Contradiction:
Area of moving objectVSReliability

Solution Approach 1:

The touch sensor area is segmented into a first touch-control area and a second touch-control area. The first area responds to touch inputs while the second area does not respond to touch inputs, preventing mishandling. This segmentation allows the device to maintain a large overall touch sensor area for display purposes while creating a safe zone at the edges where finger contact does not trigger unintended inputs.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the touch-control area is reduced to prevent mishandling, then the reliability is improved, but the display region is reduced

Engineering Contradiction:
Improvemishandling preventionVSAvoiddisplay region
Core Design Contradiction:
ReliabilityVSArea of moving object

Solution Approach 1:

The touch sensor area is divided into responsive and non-responsive zones. The first touch-control area maintains full functionality for normal operation, while the second touch-control area serves as a protective buffer zone that does not respond to touch inputs. This allows the device to maintain a large overall display region while preventing mishandling through the non-responsive edge area.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a fixed touch-control area is used to simplify the design, then the device complexity is reduced, but the adaptability to different user finger sizes and habits is reduced

Engineering Contradiction:
Improvetouch-control area configurationVSAvoiduser adaptation
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the touch-control area configuration based on detected touch patterns and user behavior. The controller can modify the boundaries between the first and second touch-control areas, or adjust the responsiveness characteristics, to adapt to different user finger sizes and handling habits while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention provides an electronic device and a method for adjusting a touch-control area thereof. The touch-control area of a touch-control display unit of the electronic device has a first touch-control area. The method for adjusting a touch-control area includes receiving a touch-control area adjustment command; adjusting the touch-control area of the electronic device to a second touch-control area in response to the touch-control area adjustment command; and displaying a tag used for representing the second touch-control area; wherein, when an input from the second touch-control area is received, an operation corresponding to the input is executed; when an input from outside of the second touch-control area is received, an operation corresponding to the input is not executed.
