Solution Overview

Problem

Existing screen protectors for 3C devices face issues such as difficulty in detachment without leaving residual glue, insufficient attachment leading to glare and touch sensitivity degradation, and increased manufacturing costs due to the use of adsorption accessories or magnetic strips.

Innovation Solution

A hanging rack type screen protector with a functional film body and L-shaped hanging rack components that allow for easy attachment and detachment without leaving residue, while maintaining touch sensitivity and reducing production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If screen protectors are mounted by direct attaching or adhering, then the attachment strength is improved, but residual glue is left on the screen and detachment becomes difficult

Engineering Contradiction:

Improveattachment strengthVSAvoiddetachment convenience

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The screen protector is divided into a functional film body and separate hanging rack components. The hanging rack portions can be detached independently from the functional film, allowing the screen protector to be removed without leaving residual adhesive on the screen while maintaining secure attachment during use.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If adsorption accessories or magnetic strips are added to enable detachment, then detachment convenience is improved, but manufacturing cost increases

Engineering Contradiction:

Improvedetachment convenienceVSAvoidmanufacturing cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The screen protector structure is segmented into a functional film body with adhesive properties and separate hanging rack components. This segmentation allows the hanging rack portions to be detached and reattached without requiring additional adsorption accessories or magnetic strips, thereby maintaining detachment convenience while avoiding increased manufacturing costs.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If adsorption accessories or magnetic strips are added, then detachment convenience is improved, but device complexity increases

Engineering Contradiction:

Improvedetachment convenienceVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The screen protector is segmented into a functional film body and hanging rack components that can be separately attached and detached. This simple segmentation approach provides detachment convenience without introducing complex adsorption accessories or magnetic strip mechanisms, thereby maintaining structural simplicity.

Inventive Principle:

Principle #1Segmentation

4Ease of operation

If screen protectors are erected in front of screens by adding adsorption accessories, then detachment convenience is improved, but attachment tightness deteriorates causing glare and touch sensitivity degradation

Engineering Contradiction:

Improvedetachment convenienceVSAvoidattachment tightness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The screen protector combines a functional film body with adhesive properties for tight attachment to the screen with hanging rack components that can be detached. This segmentation allows the functional film to maintain close contact with the screen for optimal performance while the hanging rack portions provide detachment convenience without compromising attachment tightness.

Inventive Principle:

Principle #1Segmentation

5Ease of operation

If magnetic strips are added for attachment, then detachment convenience is improved, but manufacturing cost and device complexity increase

Engineering Contradiction:

Improvedetachment convenienceVSAvoidmanufacturing cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The screen protector is segmented into a functional film body and hanging rack components that can be separately attached and detached. This simple segmentation eliminates the need for magnetic strips or other complex adsorption mechanisms, providing detachment convenience while maintaining manufacturing simplicity and cost-effectiveness.

AI summary

A hanging rack type screen protector is configured to protect a display screen of an electronic device and prevent others from peeking at images, pictures, or content presented on the display screen. The screen protector includes: a functional film body including a first left combining portion formed in an upper left region and a first right combining portion formed in an upper right region; a left hanging rack component with approximately L-shaped profile which is formed by a left hanging rack portion and a second left combining portion; and a right hanging rack component with approximately L-shaped profile which is formed by a right hanging rack portion and a second right combining portion; where the functional film body is freely hung on or freely detached or removed from the electronic device by the left hanging rack component and the right hanging rack component.
