Garment Stretch Lining With Elastic Gathers for Heat Retention
Solution Overview
Problem
Existing garments with batting or down filling lack stability in dimensional change, reducing stretchability and heat retention due to unevenness and bellows effect, while quilting fabrics and knitted structures fail to improve heat retention effectively.
Innovation Solution
A garment with a stretch lining featuring elastic thread insertion in the body width direction, forming gathers that divide space into small areas to prevent warm air escape, using a one-way fabric that is stretchable in the body width direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If batting and down are used for filling, then heat insulation is improved, but stretchability is reduced due to high density requirements
Solution Approach 1:
The lining is divided into multiple sections with elastic threads inserted at regular intervals, creating segmented gathers that allow independent movement and stretching in each section while maintaining overall heat insulation
Solution Approach 2:
Elastic threads are selectively inserted at specific locations within the lining to create localized gathers, providing stretchability only where needed while maintaining density and heat insulation in other areas
2Temperature
If the garment is designed to secure space, then heat insulation is improved, but the lining cannot fit well to the body due to bellows effect
Solution Approach 1:
The lining incorporates elastic threads that dynamically adjust the gathers to match body contours, allowing the lining to fit securely to the body while maintaining the space needed for heat retention
Solution Approach 2:
The elastic threads change the dimensional parameters of the lining by creating gathers with specific width and height ratios, enabling the lining to conform to the body while preserving thermal insulation properties
3Ease of operation
If warm air is allowed to move freely, then comfort is improved, but heat retention is reduced due to bellows effect
Solution Approach 1:
The lining is segmented into multiple gather sections that create a zigzag pattern, disrupting airflow paths and preventing warm air from escaping through the bellows effect while maintaining comfort
Solution Approach 2:
The gathers create curved, undulating surfaces that redirect airflow patterns, preventing direct vertical movement of warm air while allowing horizontal circulation for comfort
4Temperature
If fabric density is increased to prevent batting and down from coming out, then heat insulation is improved, but stretchability is reduced
Solution Approach 1:
The lining structure is segmented with elastic threads at regular intervals, creating a patterned fabric that maintains overall density for heat insulation while allowing localized stretching through the elastic gather sections
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 garment achieves high heat retention by preventing warm air escape and maintaining gather stability, ensuring comfort and ease of movement with a lightweight and flexible design.
Implementation Method 1
An elastic thread is partially inserted in the stretch fabric in a body width direction, and an elastic thread insertion potion contracts to make gathers
Implementation Method 2
The stretch fabric is a one-way fabric that is stretchable in the body width direction

AI summary
A garment 1 includes an outer fabric and a lining 2. The lining 2 is a stretch fabric. An elastic thread is partially inserted in the stretch fabric in the body width direction, and an elastic thread insertion portion 4 contracts to make gathers 5. The stretch fabric is a one-way fabric that is stretchable in the body width direction. It is preferable that a plurality of elastic threads are inserted in the stretch fabric in parallel with each other, and the gathers 5 are oriented in the body length direction. Thus, the garment has a high heat retention effect by dividing the space between the garment and the human body into small areas to prevent warm air from escaping to the outside.
