Soft Elastic Jacket Fabric Compression Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic sports jackets are too tight for ordinary sports enthusiasts, causing discomfort and excessive muscle and heart burden due to high elasticity fabrics designed for professional athletes, which are not suitable for those with less developed muscles.
Innovation Solution
A soft and elastic jacket made from an elastic weft knitted fabric with 5-15% elastic yarns and the rest non-elastic yarns, with a tightness index not exceeding 0.8 and recovery stress of 0.3-1.3 N at 30-80% elongation, providing appropriate compression and comfort for normal sports enthusiasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high elasticity fabrics are used to enhance tightening force on muscles, then sports performance is improved for professional athletes, but ordinary sports enthusiasts feel tired and discomfort due to excessive tightening
Solution Approach 1:
The patent changes the elasticity parameter of the fabric by blending elastic fibers (5-20% by weight) with non-elastic fibers, creating a fabric with controlled elastic recovery (0.05-0.25 N/mm²) that provides gentle compression suitable for ordinary sports enthusiasts rather than the high compression needed for professional athletes
2Reliability
If compression garments are worn for long time, then muscle support is provided, but burden on muscles and heart is excessively increased
Solution Approach 1:
The patent modifies the compression parameter by controlling the elastic recovery force of the fabric to 0.05-0.25 N/mm², which is significantly lower than conventional compression garments. This reduced compression parameter provides sufficient muscle support during exercise while avoiding excessive burden on muscles and heart that occurs with prolonged wear of high-compression garments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The jacket allows for free stretching and recovery with body movements, reducing energy resistance and providing a comfortable, lightweight experience during exercise, enabling healthy aerobic exercise.
Implementation Method 1
the elastic weft knitted fabric covers no less than 70 percent of the circumference of a body part of the soft and elastic jacket when the soft and elastic jacket is in a motionless state without being worn, and the elastic weft knitted fabric has a tightness index of not greater than 0.8 and a recovery stress of 0.3∼1.3 N at an elongation range of 30∼80%

AI summary
A soft and elastic jacket is provided. No less than 70 percent of the body circumference of the soft and elastic jacket is composed of an elastic weft knitted fabric, when the soft and elastic jacket is in a motionless state without being worn. The elastic weft knitted fabric is produced by knitting 5∼15% weight of elastic yarns with the rest of non-elastic yarns, and it has a basis weight of 140-200 g/m2. The elastic weft knitted fabric has a tightness index of not greater than 0.8 and a recovery stress of 0.3∼1.3 N at an elongation range of 30∼80%. The respiratory quotient is not greater than 1.05, when a person wearing the soft and elastic jacket exercises at an intensity of less than 7 Mets and a body exercise amount of not greater than 25 Mets·hr for an exercise time of less than 6 hrs. The soft and elastic jacket has a clothing pressure of 0.6 kPa or less in a motionless state, and 2.5 kPa or less in a motion state.
