Garment Heat Insulation Structure with Deformable Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat insulation structures for outdoor garments face challenges in minimizing heat loss at seams, where insulating material is absent, leading to increased manufacturing effort and thickness, and inefficient heat retention.
Innovation Solution
A heat insulation structure comprising first and second insulation elements with different uncompressed shapes that deform under body pressure to increase contact area, overlapping seams and reducing heat loss, with a design that includes a first arc with a longer length on the inner surface and a shorter arc on the outer surface, and varying ratios of arc lengths and heights to enhance sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional chamber structures (H-structure or trapezoid setup) are used to provide consistent thickness of insulating material, then heat insulation effectiveness is improved, but manufacturing effort increases considerably
Solution Approach 1:
The insulation elements are designed to change shape from an uncompressed state (providing consistent thickness) to a compressed state during wear (increasing contact area at seams). This dynamic adaptation allows the same structure to achieve both uniform insulation and seam sealing without requiring complex segmented chambers, thereby reducing manufacturing effort while maintaining thermal performance.
2Ease of manufacture
If outer and inner layers are directly sewn together to create individual chambers, then manufacturing effort is reduced, but heat loss occurs across seams where insulating material is absent
Solution Approach 1:
The insulation elements are designed with a specific uncompressed shape that allows them to expand and increase contact area at seam locations when compressed during wear. This dynamic behavior automatically seals the seams without requiring additional manufacturing steps or materials, thereby maintaining the simplicity of direct sewing while eliminating heat loss at seam areas.
3Loss of energy
If multiple layers with staggered seams are placed over each other to reduce heat loss at seams, then heat loss is reduced, but manufacturing effort increases and garment thickness increases undesirably
Solution Approach 1:
Instead of using multiple static layers with staggered seams, the invention uses single-layer insulation elements with a specialized uncompressed shape that dynamically increases contact area at seams when compressed. This approach achieves seam sealing with a single layer, avoiding the increased manufacturing complexity and additional garment thickness that would result from multiple layers.
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 structure effectively reduces body heat loss by sealing off seams and providing consistent insulation, while maintaining simplicity in manufacturing and comfort, using a combination of natural and synthetic insulating materials.
Implementation Method 1
the second uncompressed shape is deformable through pressure applied by a wearer's body when the garment is worn, which increases a size of the contact area
Implementation Method 2
a material with good heat-insulating capabilities is placed between an outer layer and an inner layer, which provides an insulating effect

AI summary
Described are heat insulation structures for a garment. The heat insulation structure includes at least one first insulation element having a first uncompressed shape, at least one second insulation element having a second uncompressed shape that is different than the first uncompressed shape, and a contact area formed when the first uncompressed shape contacts the second uncompressed shape. The second uncompressed shape is deformable through pressure applied by a wearer's body when the garment is worn, which increases a size of the contact area.
