Solution Overview

Problem

Heat retaining articles with filler materials like down feathers and batting tend to form 'cold spots' at seams, reducing their heat retention efficiency, and existing complex structures can be cumbersome.

Innovation Solution

A heat retaining article design featuring a first sheet, a second sheet, and a filler with joining sections that are interspersed with spacings, arranged in specific patterns to optimize heat retention, using stitched, bonded, or caulked sections to maintain filler distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the front fabric and back fabric are sewn together in lines to form compartments for filler, then the filler is prevented from accumulating at one end, but cold spots form at the seams where heat escapes

Engineering Contradiction:

Improvefiller distributionVSAvoidheat retention

Core Design Contradiction:

Stability of the object's compositionVSTemperature

Solution Approach 1:

The joining sections are divided into multiple discrete interspersed sections rather than continuous seams, segmenting the heat loss paths and maintaining filler distribution while reducing cold spot formation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The joining sections are strategically positioned at specific locations rather than forming continuous lines, creating localized joining points that maintain both filler stability and heat retention in the spaces between

Inventive Principle:

Principle #3Local quality

2Temperature

If partitioning walls are provided in compartments to increase heat retaining property, then heat retention improves, but the structure becomes complex

Engineering Contradiction:

Improveheat retentionVSAvoidstructure complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The structure is segmented into simple joining sections with mutual spacings rather than complex partitioning walls, achieving heat retention through distributed joining points instead of internal divisions

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The complex partitioning walls are extracted and replaced with simpler interspersed joining sections that achieve the same heat retention effect without the added structural complexity

Inventive Principle:

Principle #2Taking out (Extraction)
