Solution Overview

Problem

Existing screen protector applicators face challenges with inconvenient disassembly and assembly of the retention layer, leading to waste and affecting the flatness and parallelism of the screen protector assembly during reuse.

Innovation Solution

A screen protector assembly with a retention layer and a first matching member, where the bonding strength between the screen protector layer and the screen is greater than between the retention layer and the screen protector layer, and the connection strength between the retention layer and the first matching member is greater than between the retention layer and the screen protector layer, allowing for detachable connection to a screen protector applying assembly for easy application and reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the retention layer is forcibly detached from the protector applying assembly, then the protector applying assembly can be reused, but the flatness and parallelism of the screen protector assembly are affected

Engineering Contradiction:

Improvereusability of protector applying assemblyVSAvoidflatness and parallelism of screen protector assembly

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The connection between the retention layer and protector applying assembly is divided into multiple connection points through multiple first matching members distributed at different positions, allowing the retention layer to be detachably connected without compromising the overall flatness and parallelism when reassembled

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bonding strength between the screen protector layer and screen is designed to be greater than the bonding strength between the retention layer and screen protector layer, enabling controlled detachment at the retention layer connection points while maintaining the integrity of the screen protector assembly

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the retention layer is bonded to the protector applying assembly for reuse, then the assembly can be reused, but the bonding strength deteriorates after multiple fixing operations

Engineering Contradiction:

Improvereusability of screen protector assemblyVSAvoidbonding strength between retention layer and protector applying assembly

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The connection is segmented into multiple discrete first matching members rather than a single continuous bond, allowing individual connection points to be detached and reattached without compromising the entire assembly's bonding strength

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first matching members act as intermediary components between the retention layer and protector applying assembly, providing a reusable mechanical connection mechanism that maintains consistent connection strength across multiple assembly and disassembly cycles

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If multiple first matching members are used to detachably connect the retention layer, then the assembly can be easily disassembled and reassembled, but the device complexity increases

Engineering Contradiction:

Improveease of disassembly and assemblyVSAvoidnumber of matching members

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The first matching members are designed with universal compatibility, allowing the same type of matching member to be used at multiple positions on the retention layer, simplifying the overall design while enabling easy disassembly and reassembly through standardized connection points

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Disclosed herein are a screen protector assembly, a screen protector applying assembly and a screen protector applicator. The screen protector assembly comprises a screen protector layer, a retention layer and a first matching member. The retention layer is bonded to the screen protector layer. The first matching member is fixedly connected to the retention layer, and the first matching member is used to be detachably connected to a protector applying assembly. With the above arrangement, a detachable connection between the retention layer of the screen protector assembly and the protector applying assembly is realized, allowing the retention layer to be detached from the protector applying assembly after a protector is applied to a screen, thereby allowing the protector applying assembly to be reused, and saving costs.
