Interlocking Support Panel Assembly for Sagging Cushioned Furniture

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Cushioned furniture such as couches, chairs, and beds often lose support over time due to matting or compressing of cushioning materials and relaxation of springs, leading to reduced firmness and sag, and may not provide desired support even when new.

Innovation Solution

A system of interlocking components that form a panel assembly with predetermined flexural stiffness, which can be installed under the cushion or occupant supporting structure to enhance support by providing additional stiffness and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cushioned furniture is used over time, then the furniture provides comfort and support initially, but the support diminishes due to matting and compressing of cushioning materials

Engineering Contradiction:

Improvesupport performanceVSAvoidservice life

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The support system is divided into multiple independent components including a panel assembly with plurality of panels, support elements, and fastening mechanisms. Each component can be independently replaced or adjusted, allowing the furniture to maintain support performance throughout its service life without complete replacement

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The panel assembly and support elements are pre-configured with adjustable components and fastening mechanisms that enable users to proactively restore support before complete degradation occurs. The system allows for periodic maintenance and adjustment to prevent sagging and maintain firmness

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If cushioning materials are compressed over time, then the furniture becomes softer and more comfortable, but the firmness and support are reduced

Engineering Contradiction:

ImprovecomfortVSAvoidfirmness

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The support system provides different levels of firmness in different regions through adjustable support elements and panel configurations. Users can customize the firmness level in specific areas to balance comfort and support according to their preferences

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The panel assembly incorporates adjustable support elements that can be modified to change the firmness characteristics. The system transitions from a static cushioning structure to a dynamic one where support properties can be adjusted or restored over time

Inventive Principle:

Principle #15Dynamics

3Reliability

If furniture is repaired to restore support, then the support performance is improved, but the repair cost is expensive

Engineering Contradiction:

Improvesupport performanceVSAvoidrepair cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The panel assembly is designed as a cost-effective, replaceable component that can be easily swapped out when support performance degrades. Instead of expensive professional repairs, users can replace the entire panel assembly with a relatively inexpensive unit, restoring support performance economically

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The system incorporates user-friendly fastening mechanisms and assembly features that enable consumers to perform their own repairs and replacements without requiring professional service. This self-service capability significantly reduces repair costs by eliminating labor charges

Inventive Principle:

Principle #25Self-service

4Reliability

If new furniture is purchased to ensure adequate support, then the support performance is satisfactory, but the cost is high

Engineering Contradiction:

Improvesupport performanceVSAvoidfurniture cost

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Rather than replacing the entire furniture piece, the support system is segmented into replaceable panel assemblies. Users can purchase and install only the support component that has degraded, significantly reducing the cost compared to buying new furniture while restoring adequate support performance

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modular panel assembly allows users to discard only the worn support component while retaining the rest of the furniture structure. This selective replacement recovers the value of the existing furniture investment while achieving the support performance of new furniture at a fraction of the cost

Inventive Principle:

Principle #34Discarding and recovering

AI summary

Panel assemblies designed and configured to be installed into cushioned and other occupant-supporting furniture to increase the support provided to one or more occupants of the furniture. Each panel assembly is composed of interconnecting components, such as panels and slats. The components are interconnected in any one or more of a variety of manners, including side-to-side, overlapped, and stacked, and combinations thereof. Each panel assembly can be made from one or more kits of components that can be provided along with instructions, such as assembly instructions and installation instructions.
