Solution Overview

Problem

Existing screen protector applicators with integrated phone brackets cannot maintain flatness during application, affecting the quality of screen protector adherence, and are limited to a single device type, 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 handle for stable support and storage.

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 screen protector applicator can be used as a mobile phone bracket to avoid waste, but the bracket cannot maintain flat when the screen protector is stuck to the mobile phone, which may easily affect quality of the screen protector application

Engineering Contradiction:
Improvedual function as bracket and applicatorVSAvoidflatness during application
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The device is divided into separate functional modules: the bracket structure is separated from the application surface. The bracket can be folded out independently from the positioning box, allowing the application surface to remain flat while providing bracket functionality when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket is designed with movable and foldable connections, transitioning from a static integrated structure to a dynamic deployable one. The bracket can be folded out for use and folded in for storage, adapting its state based on functional requirements without compromising the flatness of the application surface.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the screen protector sticking box is designed for a single function with high pertinence, then it can only be applied to one type of electronic device, but after the screen protector is stuck, the screen protector sticking box has no other uses, which easily leads to a waste of resources

Engineering Contradiction:
Improveprecision for specific device typeVSAvoidmulti-functionality
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The screen protector applicator is designed with a detachable and foldable bracket that can be configured for different device types. The positioning frame and adjustable bracket allow the same device to serve multiple functions: precise screen protector application and versatile device support at various angles.

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

3Adaptability or versatility

If the bracket is made foldable and movable, then the applicator can support electronic devices at different angles, but the structure becomes more complex

Engineering Contradiction:
Improveadjustable support anglesVSAvoidmovable bracket structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bracket is designed to fold into and nest within the positioning box when not in use. The movable components are arranged to occupy minimal space when folded, creating a compact integrated structure that reduces overall complexity while maintaining adjustability functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A screen protector applicator with a bracket includes a screen protector positioning box, wherein a positioning frame is arranged on one side of the screen protector positioning box, and the positioning frame and the screen protector positioning box are integrated, a positioning strip is arranged on the side of the screen protector positioning box, a support plate is movably arranged on the other side of the screen protector positioning box, a bracket is movably arranged on the positioning frame, and a mounting groove is further arranged on a side of the bracket close to the screen protector positioning box. The function of the screen protector positioning box is expanded, by movably arranging a bracket on the screen protector positioning box, so that the screen protector positioning box has the functions of assisting screen protector application and supporting the electronic device.
