Solution Overview

Problem

Existing anti-overturn devices for furniture are cumbersome, difficult to install on both sides and backs, require complex adjustments, and are not easily adaptable to different orientations, leading to increased production costs and storage complexity.

Innovation Solution

A simple and versatile anti-overturn device with a first element fixed to the wall and a second element that can be reversibly attached to the furniture, featuring a rotating pin and lever mechanism that allows for easy installation and operation on both sides and backs without requiring adjustments to the furniture's feet, enabling secure locking and unlocking with a single control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex adjustable engaging means are used, then the device can be adjusted vertically and detached, but the device becomes cumbersome and cannot be mounted on the back of furniture

Engineering Contradiction:

Improveadjustability and detachabilityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into two independent elements: a first element fixed to the wall and a second element fixed to the furniture. This segmentation allows each element to have a simple, fixed structure while the system as a whole provides adjustability and detachability through the engagement mechanism between the two elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adjustment and detachment functions are extracted from the individual elements and implemented through the engagement mechanism between the first and second elements. The second element can be detached from and reattached to the first element at different positions, providing adjustability without requiring complex mechanisms within each element.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If multiple specific devices are used for right and left sides, then each side can be properly secured, but production and storage are complicated and costs increase

Engineering Contradiction:

Improvesecuring effectivenessVSAvoidproduction and storage simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The device is designed as a universal system where the first element and second element can be used on any side of the furniture (left, right, or back) without modification. The engagement mechanism works the same way regardless of orientation, eliminating the need for different specific devices for different sides and simplifying production and storage.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the engaging means are shifted and furniture moved against the wall, then proper engagement can be achieved, but the activation process becomes complicated

Engineering Contradiction:

Improveengagement reliabilityVSAvoidactivation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The first element is pre-fixed to the wall at the desired position, and the second element is pre-fixed to the furniture. The engagement mechanism is designed so that when the furniture is moved against the wall, the elements automatically engage without requiring manual shifting or complex adjustment steps, simplifying the activation process while maintaining reliable engagement.

Inventive Principle:

Principle #10Preliminary action

4Device complexity

If L-shaped brackets are used, then the device is simple and economic, but no adjustment after mounting is allowed

Engineering Contradiction:

Improvestructural simplicityVSAvoidadjustability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

While maintaining the simple L-shaped bracket structure for fixing to the wall and furniture, the device incorporates a detachable engagement mechanism that allows the second element to be removed and reattached at different vertical positions. This dynamic capability enables adjustment after mounting without requiring complex mechanisms in the basic structure.

Inventive Principle:

Principle #15Dynamics
