Solution Overview

Problem

Existing screen protector applicators with integrated mobile phone brackets cannot maintain flatness during application, affecting the quality of screen protector application and are limited to single-device use, leading to resource waste.

Innovation Solution

A screen protector applicator with a bracket that includes a movable support plate and U-shaped bracket, allowing for dual functions of screen protector application and device support, with features like a positioning frame, mounting grooves, and a support plate that rotates 90° for stable support without affecting flatness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the mobile phone bracket base is integrated on the front side of the bracket, then the applicator can support electronic devices, but the bracket cannot maintain flatness during screen protector application

Engineering Contradiction:
Improvesupport functionVSAvoidflatness
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The bracket base is separated from the main bracket body and can be rotated independently. This segmentation allows the bracket base to be positioned at different angles - flat when not in use and tilted when supporting a device - thus resolving the contradiction between support functionality and flatness maintenance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket base is designed with rotational capability, transforming it from a static integrated structure to a dynamic adjustable component. This allows the bracket to adapt its configuration based on usage needs, maintaining flatness during application while providing support when required.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the screen protector sticking box is designed for a single function, then it can be applied to one type of electronic device, but it cannot be reused after application

Engineering Contradiction:
Improvesingle function designVSAvoidreusability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The bracket is designed with adjustable rotational capability that allows it to accommodate different electronic device sizes and angles. By rotating the bracket base to different positions, the same applicator can support various device types, transforming a single-function tool into a multi-functional device that maintains reusability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
