Sealable Duvet Structure for Comforter Retention

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional duvets lack efficient mechanisms for securing and maintaining the comforter in place, particularly when folded or partially zipped, leading to potential displacement and loss of warmth.

Innovation Solution

A duvet design featuring sealable side edges with zipper assemblies and internal clips to securely fasten the comforter, ensuring it remains in place by temporarily attaching three side edges via zippers or other attachment means like buttons or Velcro, and utilizing clips near internal corners to hold the comforter firmly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional duvets are used without securement mechanisms, then the structure is simple and easy to manufacture, but the comforter displaces and warmth is lost when folded or partially zipped

Engineering Contradiction:

Improvecomforter position stabilityVSAvoidduvet structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The duvet is divided into multiple functional components: zipper assemblies for sealing side edges, clips for corner securing, and a comforter retention system. This segmentation allows each component to perform its specific function effectively while maintaining overall system reliability for comforter position stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The zipper assemblies are pre-positioned along the side edges and the clips are pre-attached at corners before the duvet is assembled with the comforter. This preliminary placement ensures that when the comforter is inserted, the securement mechanisms are already in position to prevent displacement, eliminating the need for additional adjustments during use.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If zipper assemblies are added to seal side edges, then the comforter is secured better, but the manufacturing process becomes more complex

Engineering Contradiction:

Improvecomforter retentionVSAvoidduvet assembly ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The zipper assemblies serve multiple functions: they seal the side edges to prevent comforter displacement, provide a secure closure mechanism that can be partially opened for adjustment, and maintain the structural integrity of the duvet. This multi-functionality justifies the additional manufacturing complexity by delivering comprehensive comforter retention.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If clips are added at internal corners, then the comforter is held firmly in place, but the device complexity increases

Engineering Contradiction:

Improvecomforter position stabilityVSAvoidnumber of attachment components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Clips are strategically placed only at the internal corners of the duvet where they provide maximum securing effectiveness. This localized placement addresses the specific problem of corner displacement without adding clips to all edges, thereby minimizing the increase in device complexity while maintaining reliable comforter position stability.

Inventive Principle:

Principle #3Local quality
