Solution Overview

Problem

Furniture assembly is often time-consuming and labor-intensive, requiring tools, and rearrangement or adjustment is difficult once installed, posing a burden on personnel.

Innovation Solution

A supporting assembly comprising a shaft member with teeth, base members with loop structures and legs, and locking members that allow easy assembly and adjustment without tools, using a teeth-engagement mechanism for secure locking and adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional furniture assembly methods are used, then structural stability is achieved, but assembly time and labor intensity increase significantly

Engineering Contradiction:

Improvestructural stabilityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The supporting assembly is divided into modular components including shaft members with teeth, base members with loop structures, and locking members. These segmented parts can be quickly connected through tooth engagement mechanisms without requiring complex assembly procedures, thereby reducing assembly time while maintaining structural integrity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces traditional mechanical fastening systems (screws, bolts, welds) with a tooth engagement and locking mechanism. The teeth on shaft members engage with the loop structure of base members, and locking members secure the connection, eliminating the need for tools and complex mechanical operations while ensuring structural stability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional furniture assembly methods are used, then structural stability is achieved, but the process becomes labor-intensive requiring tools

Engineering Contradiction:

Improvestructural stabilityVSAvoidassembly ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The supporting assembly is designed to be self-assembling through the interaction of its components. The teeth on shaft members automatically engage with the loop structure of base members when brought together, and the locking members can be simply threaded on to secure the connection. This self-service mechanism eliminates the need for external tools and complex assembly operations, making the process easy to perform while ensuring stable structural connection

Inventive Principle:

Principle #25Self-service

3Reliability

If furniture is assembled with fixed configuration, then structural stability is maintained, but rearrangement and adjustment become difficult

Engineering Contradiction:

Improvestructural stabilityVSAvoidrearrangement flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The supporting assembly incorporates dynamic characteristics through its modular design and locking mechanism. The locking members can be easily engaged and disengaged, allowing the furniture to transition between fixed and reconfigurable states. This enables stable operation when assembled while maintaining ease of rearrangement, as components can be quickly locked into new positions without compromising structural integrity

Inventive Principle:

Principle #15Dynamics
