Solution Overview
Problem
Current touch devices face challenges in providing optimal touch accuracy and sensitivity, particularly in the design of the touch module and front frame element, which affect user interaction.
Innovation Solution
A touch device design featuring a touch module with a front frame element that includes a covering portion with specific thickness and distance configurations, such as between 0.1 mm and 1.6 mm thickness and 2 mm to 8 mm distance from the touch display zone, and an inclined surface with an included angle between 1° and 20°, enhancing user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the covering portion thickness is increased to provide structural support, then the structural strength is improved, but the touch sensitivity deteriorates
Solution Approach 1:
The patent optimizes the covering portion thickness parameter to a specific range (0.1mm-1.6mm) that balances structural strength and touch sensitivity. This parameter change resolves the contradiction by finding the optimal value that provides sufficient support while maintaining thin enough profile for sensitive touch detection.
Solution Approach 2:
The patent applies different thickness characteristics to different regions of the covering portion. The outer edge thickness is specifically controlled (0.1mm-1.6mm) while the inner region may have different properties, creating local quality variations that optimize both strength and touch sensitivity in their respective locations.
2Shape
If the covering portion is positioned closer to the touch display zone to reduce bezel width, then the device aesthetics are improved, but the touch accuracy deteriorates
Solution Approach 1:
The patent establishes a specific distance parameter range (2mm-8mm) between the covering portion outer edge and the touch display zone. This parameter optimization resolves the contradiction by maintaining sufficient distance for accurate touch detection while minimizing the bezel width for aesthetic purposes.
Solution Approach 2:
The patent introduces the vertical dimension by creating an inclined surface on the covering portion that transitions from the outer edge toward the touch display zone. This dimensional change allows the covering portion to be positioned closer aesthetically while the inclined surface maintains the functional distance needed for touch accuracy through a gradual transition rather than a sharp drop.
3Manufacturing precision
If the covering portion thickness is increased to improve structural support, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The patent simplifies the structure by specifying a single thickness parameter range (0.1mm-1.6mm) for the covering portion outer edge, avoiding the need for complex multi-layer or variable-thickness structures. This parameter change achieves sufficient structural support while maintaining manufacturing simplicity.

AI summary
A touch device comprises a touch module and a front frame element. The touch module includes a surface having a touch display zone. The front frame element is disposed at an outer edge of the touch module and includes a covering portion located on the surface of the touch module. The thickness of an outer edge of the covering portion adjacent to the touch display zone is between 0.1 mm and 1.6 mm, and the minimum distance from the outer edge of the covering portion to the touch display zone is between 2 mm and 8 mm.
