Solution Overview

Problem

Existing comforter covers face issues such as worn ends due to scuffing, difficulty in inserting and distributing the comforter evenly, and inadequate security, leading to unevenness and reduced comfort.

Innovation Solution

A comforter cover design featuring a sleeve with two open ends and end caps, utilizing a fastening system with buttons and buttonholes for secure closure, allowing easy assembly and providing dirt sealing and wear protection, with interchangeable end caps for aesthetic versatility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rectangular fabric sack with an opening is used as a comforter cover, then the comforter can be easily inserted, but the ends are prone to wear from scuffing and the cover cannot secure the comforter stably

Engineering Contradiction:
Improveease of inserting comforterVSAvoidstability of comforter in cover
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The comforter cover is divided into three main segments: a sleeve portion for receiving the comforter, and two separate end cap portions that can be independently attached to the ends of the sleeve. This segmentation allows each part to perform its specific function optimally - the sleeve provides easy insertion while the end caps provide secure closure and protection against wear.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The end caps are designed with fastening members (buttons, snaps, or Velcro) that enable preliminary securing of the comforter within the sleeve before final use. This preliminary action prevents the comforter from shifting or becoming unevenly distributed during subsequent use, thereby maintaining stability.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If rudimentary buttoning or fasteners are used along the edges of the cover, then the cover can be closed, but dirt can enter between the fasteners and the ends wear from scuffing

Engineering Contradiction:
Improvesimplicity of closure mechanismVSAvoiddirt ingress and wear
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The end caps are designed to extend beyond the fastening line, creating an overlapping flange structure that acts as a flexible barrier. This extension provides a dirt seal that prevents harmful factors like dust and debris from entering between the fasteners, while the robust end cap material protects against scuffing and wear.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The solution moves from a one-dimensional fastening approach to a two-dimensional coverage approach by extending the end caps beyond the fastening line. This dimensional extension creates an overlapping structure that seals the gap between fasteners, preventing dirt ingress while maintaining manufacturing simplicity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the comforter is inserted through a single opening, then the cover can be assembled, but the comforter is difficult to distribute evenly throughout the cover

Engineering Contradiction:
Improvestructure of cover openingVSAvoideven distribution of comforter
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The single opening is segmented into two separate openings located at opposite ends of the sleeve. This allows the comforter to be inserted from one end and distributed evenly by working from both ends simultaneously, making it easier to achieve uniform distribution without increasing overall structural complexity.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If the comforter is not secured within the cover, then the cover structure remains simple, but the comforter moves or shifts during use reducing comfort

Engineering Contradiction:
Improvesecuring mechanismVSAvoidstability of comforter position
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The securing mechanism is segmented into multiple fastening points distributed along the edges of the end caps and sleeve. This segmentation provides multiple anchoring points that effectively prevent comforter movement without requiring a single complex securing mechanism, thereby maintaining relative structural simplicity while achieving reliable position stability.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed is a comforter cover having a sleeve and one or more end caps. The sleeve can have one or two open ends and the comforter can be received into the sleeve through one of the open ends. The end cap or end caps can be fittable over the sleeve and comforter to close the open end or ends of the sleeve. A fastening system can fasten the end cap or end caps to the sleeve. The fastening system can be provided by buttons attached to the comforter which button through buttonholes in the sleeve and end caps, or by closable fasteners passing through openings in the sleeve, the end caps and also in the comforter, or other suitable fastening devices. The comforter cover can protect the comforter against wear and tear, promotes cleanliness, can seal in an esthetic manner and lends itself to a variety of ornamentation and visual effects.
