Multiuse foldable furniture

Solution Overview

Problem

Existing multi-use foldable furniture is inconvenient to fold, occupies large space in the folded state, and lacks flexibility in converting between usage states.

Innovation Solution

A multi-use foldable furniture design featuring a main body with hinged side supports, retracting sleeves, and a supporting connector that allows for easy conversion between chair, table, and trolley states, with optional roller sets and a push handle for enhanced mobility and convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing multiuse foldable furniture is designed to convert between chair and table, then resource utilization improves, but folding convenience deteriorates and folded size increases

Engineering Contradiction:

Improvemulti-functionalityVSAvoidfolding convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The side supports are divided into front support and back support as separate segments that can independently fold and retract. This segmentation allows each component to move independently during folding operations, making the overall folding process more convenient and manageable while maintaining multi-functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The retracting sleeve is sleeved on the front support, creating a nested structure where the back support extends through the retracting sleeve. This nesting arrangement allows compact folding by enabling components to slide into and stack within each other, reducing folded size while preserving chair and table conversion capabilities.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If existing multiuse foldable furniture is designed to convert between chair and table, then resource utilization improves, but folded space occupation increases

Engineering Contradiction:

Improvemulti-functionalityVSAvoidfolded size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The retracting sleeve is sleeved on the front support, creating a nested structure where the back support extends through the retracting sleeve. This nesting arrangement allows compact folding by enabling components to slide into and stack within each other, reducing folded size while preserving chair and table conversion capabilities.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The side supports utilize dynamic sliding and retracting mechanisms rather than fixed rigid connections. The front support and back support can dynamically adjust their positions and angles during folding, allowing the structure to collapse into a more compact form factor that occupies less storage space while maintaining structural integrity during use.

Inventive Principle:

Principle #15Dynamics

3Ease of manufacture

If existing multiuse foldable furniture uses simple hinged connections, then manufacturing simplicity improves, but conversion flexibility deteriorates

Engineering Contradiction:

Improvestructural simplicityVSAvoidconversion flexibility

Core Design Contradiction:
