Solution Overview

Problem

Existing quick assembly furniture is often bulky for shipping, requires tools for assembly, and can be difficult to disassemble without damaging components, leading to increased shipping costs and consumer frustration.

Innovation Solution

A knock-down furniture kit using panels connected with mating grooves, wedges, locking pins, and cleats that allow for easy assembly and disassembly without tools, minimizing shipping volume and ensuring stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If furniture is shipped pre-assembled, then assembly stability is improved, but shipping volume increases and shipping costs increase

Engineering Contradiction:

Improveassembly stabilityVSAvoidshipping volume

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The furniture is divided into multiple panels and components that can be shipped separately in compact forms, then assembled at the destination to form the complete furniture piece, reducing shipping volume while maintaining assembly stability through proper connection mechanisms

Inventive Principle:

Principle #1Segmentation

2Volume of stationary object

If furniture is shipped in multiple components, then shipping volume is reduced, but assembly complexity increases and requires tools

Engineering Contradiction:

Improveshipping volumeVSAvoidassembly complexity

Core Design Contradiction:

Volume of stationary objectVSDevice complexity

Solution Approach 1:

The connection mechanisms are designed to be self-assembling without requiring external tools or complex procedures, allowing consumers to easily assemble the furniture components using simple manual operations

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Multiple connection functions (alignment, securing, and locking) are merged into integrated connection mechanisms that combine several features into single components, reducing assembly steps and complexity

Inventive Principle:

Principle #5Merging (Combining)

3Strength

If traditional rigid joints are used, then structural strength is improved, but disassembly capability is lost and components may be damaged

Engineering Contradiction:

Improvejoint strengthVSAvoiddisassembly ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The connection mechanisms transition from fixed rigid states to reversible states, allowing the joints to be securely locked during use but easily released when disassembly is needed, providing both strength and disassembly capability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connection mechanisms are designed to be reusable rather than consumable, allowing components to be disconnected and reconnected multiple times without damage, enabling relocation and reconfiguration of the furniture

Inventive Principle:

Principle #34Discarding and recovering

4Loss of energy

If consumer assembly is required, then shipping costs are reduced, but assembly time increases and consumer frustration increases

Engineering Contradiction:

Improveshipping costVSAvoidassembly time

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

Connection features and alignment elements are pre-positioned on the furniture components during manufacturing, so that assembly requires only simple insertion and connection actions by the consumer, minimizing assembly time and effort

Inventive Principle:

Principle #10Preliminary action

AI summary

A kit is provided that, when assembled, forms a unit of furniture. The kit includes side panels that can reversibly slide into an opening formed in the sides of the front and side panels. The kit may include multiple locking pins and cleats to restrict movement of the top and side panels. The kit may include positioning wedges and/or locking wedges to restrict relative movement of the panels and thus improve the stability of the unit. Also provided are methods of assembling the unit of furniture.
