Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional touch panels rely on ink printing methods to achieve a semitransparent light shielding rate, which are limited in flexibility and precision, particularly for adjusting light shielding rates in non-touch areas with ambient light sensors or infrared holes.

Innovation Solution

The touch panel employs an atomizing process, such as sandblasting, to create interlaced atomized and non-atomized areas on the surface of a transparent base board, allowing for adjustable light shielding rates by controlling the size of the atomized area, thereby achieving a cloudy or hazy opaque appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If ink printing method is used to form semitransparent area, then the light shielding rate can be adjusted, but the flexibility and precision are limited

Engineering Contradiction:

Improvelight shielding rate adjustment precisionVSAvoidflexibility in meeting light shielding demands

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent changes the physical state and surface properties of the base board material through atomization treatment. By controlling the degree of atomization (from slight to severe), the light shielding rate can be precisely adjusted. This parameter change approach replaces the ink printing method with a more flexible physical treatment method that offers better control over light shielding characteristics.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the chemical ink printing system with a physical atomization system. Instead of depositing ink layers to achieve light shielding, the method uses mechanical or physical atomization of the base board surface to create light-shielding structures. This substitution provides greater flexibility and precision in controlling the light shielding rate.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Illumination intensity

If semitransparent printing ink is deposited, then the light shielding rate can be achieved, but the method is limited in flexibility

Engineering Contradiction:

Improvelight shielding rateVSAvoidflexibility

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent achieves light shielding by changing the surface parameters of the base board through atomization. By adjusting atomization parameters (such as atomization intensity, pattern, and distribution), the light shielding rate can be precisely controlled to meet different illumination requirements while maintaining high flexibility.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If conventional ink printing is used, then semitransparent area can be formed, but precision and flexibility are compromised

Engineering Contradiction:

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent replaces the multi-step ink printing manufacturing process with a direct physical atomization process. This substitution maintains ease of manufacture while significantly improving the precision of light shielding rate control, as the atomization process can be directly controlled to achieve the desired light shielding effect in a more straightforward manner.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
