Solution Overview

Problem

The small display screens of wearable electronic devices like smart watches and smart bracelets are often obstructed by a user's finger during touch operations, leading to inconvenient user experiences.

Innovation Solution

A touch control system and method that transfers the touch operation area to a preset area outside the display region, creating a virtual touch area, thereby avoiding obstruction of the display panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If touch operations are performed on the display screen of wearable devices, then user interaction is enabled, but the display panel is blocked by the user's finger

Engineering Contradiction:
Improvetouch operationVSAvoiddisplay panel visibility
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent extracts the touch operation function from the display screen area and relocates it to a separate touch detection area. The touch detection device is positioned adjacent to the display region, allowing users to perform touch operations outside the display area, thereby preventing finger obstruction of the display panel while maintaining full touch functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

2Area of stationary object

If the touch detection area is extended outside the display region, then display obstruction is avoided, but device structure becomes more complex

Engineering Contradiction:
Improvedisplay panel visibilityVSAvoidtouch control system structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent combines the touch detection device with the existing display structure of the wearable device. The touch detection area is integrated into the overall device architecture, sharing structural support and control systems with the display region, thereby minimizing additional structural complexity while extending the functional area.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A touch control system, a touch control display system and a touch control interaction method are disclosed. The touch control system includes a touch detection device (110), a touch area positioning device (120) as well as a processing device (130) connected to the touch detection device (110) and the touch area positioning device (120) by way of a signal connection. The touch detection device (110) is configured to detect an occurring position of a touch event in a preset area (140) and to transmit information on the occurring position of the touch event to the processing device (130). The touch area positioning device (120) is configured to emit a first light beam (151) and a second light beam (152) to form a first pattern (161) at the first position and a second pattern (162) at the second position. The processing device (130) is configured to process the information to obtain the occurring position of the touch event, and to obtain the first position and the second position. The touch control system can prevent touch operations from blocking a display screen.
