Garment Thermal Insulation Structure Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garment insulation structures suffer from heat loss through seams due to the direct contact of outer and inner layers, which allows cold air to penetrate and heat to escape, as no insulation material is present in these areas.
Innovation Solution
A thermal insulation structure comprising multiple insulation elements with different initial shapes, where the second insulation element deforms upon wear to increase contact area and is connected to a third insulation element that covers the seams, forming a cavity filled with a heat-storing medium like air or down, thereby minimizing heat loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer layer and inner layer are sewn or stitched directly to each other to create chambers, then the insulation material is distributed and secured, but heat escapes through the seams and cold air penetrates into the garment
Solution Approach 1:
A sealing element is introduced as an intermediary component between the outer layer and inner layer at the seam regions. This sealing element prevents direct contact between the layers, blocking heat escape and cold air penetration through the seams while still allowing the chambers to be formed and filled with insulation material.
Solution Approach 2:
The sealing element is designed as a flexible component that can adapt to the seam geometry and maintain the seal between the outer and inner layers. This flexible sealing structure effectively blocks thermal transfer and air penetration along the seam lines without rigidly constraining the garment's movement.
2Stability of the object's composition
If insulation material is distributed over individual chambers, then undesired slipping or redistribution of insulation material is avoided, but no insulation material is present in the seam regions where outer and inner layers directly contact
Solution Approach 1:
The sealing element serves as a mediator that extends the insulation coverage to the seam regions. By positioning the sealing element at the seams, it provides thermal insulation where the outer and inner layers would otherwise directly contact, complementing the chamber-based insulation distribution.
Solution Approach 2:
The thermal insulation system is segmented into multiple components: insulation material within chambers and sealing elements at seam regions. This segmentation allows each component to perform its specific function - chambers provide bulk insulation while sealing elements provide targeted insulation at heat loss-prone seam areas.

AI summary
The invention relates to a garment with a thermal insulation structure. The thermal insulation structure comprises a first insulation element with a first insulation layer and a second insulation element with a second insulation layer, wherein the second insulation element has a different initial shape than the first insulation element and the first insulation element is connected to the second insulation element. The second insulation element is deformed when the garment is worn by a pressure on an inner side of the thermal insulation structure, so that a contact area, in which the first insulation element contacts the second insulation element, is increased. The thermal insulation structure further comprises a third insulation element with a third insulation layer.
