Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face difficulties in accurately interacting with touch areas on electronic devices due to unclear boundaries between touch and non-touch areas, leading to unintended function triggers and reduced operation accuracy.

Innovation Solution

Incorporating non-touch areas adjacent to touch areas that do not respond to touch operations, with the touch areas displaying target objects in a distinct preset style upon detection, enhancing visibility and interactivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If touch areas are made larger to improve ease of operation, then ease of operation is improved, but boundary clarity between touch and non-touch areas deteriorates, leading to unintended function triggers

Engineering Contradiction:

Improveease of operationVSAvoidboundary clarity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The screen is segmented into distinct touch areas and non-touch areas with clear boundaries. The touch area is further segmented into sub-areas (first touch area, second touch area) with different functions, allowing precise control while maintaining clear visual distinction between interactive and non-interactive regions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the screen are assigned different properties: touch areas have touch sensitivity and visual characteristics (first display area, second display area), while non-touch areas have no touch sensitivity. This local differentiation allows each region to be optimized for its specific function while maintaining overall boundary clarity.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If non-touch areas are added adjacent to touch areas to improve operation accuracy, then operation accuracy is improved, but device complexity increases

Engineering Contradiction:

Improveoperation accuracyVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The non-touch areas are merged with the display system, using the same display hardware to render both touch-sensitive and non-touch-sensitive regions. This integration allows the non-touch areas to serve as visual boundaries without requiring separate physical components, thus reducing overall device complexity while improving operation accuracy.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display system serves multiple functions: it displays visual content in non-touch areas and responds to touch operations in touch areas. The same physical screen infrastructure is used for both display and touch interaction, eliminating the need for separate boundary indication mechanisms and reducing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A target object display method and apparatus, an electronic device, and a non-transitory computer-readable medium. Said method includes: displaying a page, the page comprising a touch region and at least one non-touch region adjacent to the touch region, the at least one non-touch region not responding to a preset touch operation, and the touch region being used for displaying a target object; and in response to the detection of the touch operation in the touch region, displaying the target object in the touch region in a first preset pattern.
