Solution Overview

Problem

Existing methods for assembling furnishing constructs, such as mattresses, are labor-intensive and require skilled workers, and often involve complex machinery that is difficult to operate.

Innovation Solution

A method of forming a mattress assembly by providing a cover-top panel compact with a drape affixed to a top panel, inverting the drape to engage a supporting core, and securing it with a detachable margin to enclose the core, using a drape with fixed and free margins to facilitate efficient assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional manual assembly methods are used for mattresses, then assembly precision and quality can be maintained, but labor intensity increases and productivity decreases

Engineering Contradiction:

Improveassembly speedVSAvoidassembly complexity

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The mattress is divided into separate modular components: a core assembly and a cover-top panel assembly. These modules are manufactured independently and then joined together through the drape integration process, enabling parallel production and reducing overall assembly time while maintaining quality through standardized connection interfaces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The drape is pre-attached to the top panel during cover assembly manufacturing, and the core is prepared separately with its border skirt. This preliminary preparation of components allows for rapid final assembly by simply integrating the pre-prepared modules, significantly improving productivity without requiring complex assembly machinery.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If complex machinery is used for assembly operations, then productivity increases, but device complexity and operational difficulty increase

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidmachinery complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The drape with border skirt automatically integrates with the core assembly through its own structural design features (fixed margin, free margin, and border skirt configuration). The assembly process relies on the self-aligning and self-securing properties of the drape structure rather than requiring complex external machinery, thereby improving productivity while keeping equipment simple.

Inventive Principle:

Principle #25Self-service

3Manufacturing precision

If skilled workers are used for manual assembly, then assembly quality is maintained, but labor costs and production time increase

Engineering Contradiction:

Improveassembly qualityVSAvoidassembly time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The drape structure incorporates specific geometric parameters and material properties that enable automatic alignment and secure attachment during assembly. The fixed margin, free margin, and border skirt dimensions are designed to ensure proper fit and attachment without requiring skilled manual intervention, thereby maintaining assembly quality while reducing time loss.

Inventive Principle:

Principle #35Parameter changes

AI summary

Described herein is a method of forming a mattress (and product thereof) including providing a cover-top panel compact that includes a top panel having one or more filler layers and a drape that is affixed to the top panel at a first margin. The method entails detaching the drape at a second margin and inverting the drape to engage a supporting core, thereby completing the mattress assembly.
