Solution Overview

Problem

Existing protective arrangements for openings, such as insect screens, require time-consuming manual installation due to the need for mechanical elements like hinges and mounting brackets.

Innovation Solution

A kit that utilizes magnets to attach and pivot a protective device to a frame, eliminating the need for mechanical elements by using at least one magnet to secure and define the pivoting axis, allowing easy installation and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical elements like hinges and hanging brackets are used to attach the protective device, then the protective device can be securely held to the frame, but the installation effort and complexity increase significantly

Engineering Contradiction:

Improvesecure attachmentVSAvoidinstallation effort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical attachment elements (hinges, brackets) with a magnetic attachment system. Magnets are integrated into the frame and interact with magnetizable elements on the protective device to provide secure holding, eliminating the need for complex mechanical fastening components and significantly reducing installation effort.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts and removes the mechanical attachment components (hinges, brackets) from the system and replaces them with a simplified magnetic attachment mechanism. This extraction of unnecessary mechanical elements directly reduces installation complexity while maintaining secure attachment through magnetic forces.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If multiple mechanical components are used for attachment, then the protective device can be securely mounted, but the device complexity increases

Engineering Contradiction:

Improvesecure mountingVSAvoidnumber of mechanical elements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent substitutes the complex mechanical system of multiple hinges, brackets, and fasteners with a simplified magnetic attachment system. The magnets and magnetizable elements provide secure mounting through magnetic attraction, dramatically reducing the number of mechanical components needed and simplifying the overall device structure.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent merges the attachment function into a single magnetic interaction system rather than using multiple separate mechanical components. The magnets integrated into the frame work together with magnetizable elements to provide both positioning and securing functions, consolidating what would otherwise require multiple discrete mechanical parts.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If traditional mechanical attachment methods are used, then the protective device can be firmly fixed to the frame, but manual effort and time for installation increase

Engineering Contradiction:

Improvefirm fixationVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces time-consuming mechanical attachment procedures with rapid magnetic attachment. The magnets automatically align and secure the protective device to the frame through magnetic attraction, eliminating the need for manual fastening operations and significantly reducing installation time while maintaining firm fixation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic attachment system provides self-aligning and self-securing behavior where the magnets automatically find their position and establish firm fixation through magnetic attraction. This self-service characteristic eliminates the need for complex manual alignment and fastening operations, reducing installation time without compromising fixation reliability.

Inventive Principle:

Principle #25Self-service
