Solution Overview

Problem

Existing furniture connection methods require a large number of separate elements and various tools, making them complex and unreliable for securing panels at predetermined angles.

Innovation Solution

An interlocking means comprising an elongated element and a brace element, which allows for the secure connection of two panels and a leg at a predetermined angle using a single interconnection element and securing means, such as a screw and threaded hole, or a bayonet coupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate elements and tools are used to connect panels, then the connection can be achieved, but the device complexity and number of components increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate connection elements into a single integrated corner post brace that simultaneously connects multiple panels. The L-shaped configuration integrates functions that previously required separate brackets, rods, and nuts into one unified component that can be installed with a single tool.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The corner post brace is designed as a universal connection element that can connect different types of panels (side panels, end panels) at predetermined angles. The single component performs multiple connection functions that previously required different specialized elements for different panel configurations.

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

2Reliability

If multiple separate elements and tools are used to connect panels, then the connection can be achieved, but the ease of operation decreases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By merging multiple connection operations into a single corner post brace installation, the patent reduces the number of tools and steps required. The single component design allows workers to complete multiple panel connections simultaneously rather than sequentially installing separate elements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The corner post brace is pre-configured with the correct geometry and connection features before installation. The L-shaped configuration and integrated connection points are prepared in advance, eliminating the need for on-site assembly of multiple separate components and reducing installation complexity.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If traditional corner post braces are used, then panels can be connected, but the adaptability to different panel configurations is limited

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidpanel configuration flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The corner post brace is designed as a universal connector that can accommodate different panel types and configurations. The standardized connection interface allows the same component to be used for connecting side panels, end panels, and various panel combinations, replacing the need for multiple specialized connection elements.

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

Solution Approach 2:

The patent segments the connection function into a modular corner post brace that can be independently applied to different panel junctions. This modular design allows flexible adaptation to various furniture configurations while maintaining manufacturing simplicity through standardization of the individual modules.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention relates to an interlocking means for connecting a first panel, second panel and a leg of a piece of furniture with each other, wherein the interlocking means comprises an elongated element and a brace element. The elongated element comprises a portion configured to be attached to a first surface of the first panel and a first surface of the second panel and either a securing means configured to receive an interconnection element protruding from the leg or an interconnection element config- ured to match a securing means formed in the leg. The brace element comprises a portion configured to be attached to a second surface of the first panel and a second surface of the second panel and a through opening configured to receive the intercon- nection element.
