Compression Garment Macroscopic Hook Spacer Fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression garments face difficulties in donning and applying a consistent compression force due to the limitations of hook-and-loop fasteners, which reduce breathability and comfort by requiring additional layers and can lead to skin irritation.
Innovation Solution
A compression garment featuring a spacer fabric with an inner and outer layer connected by spacer yarns, incorporating macroscopic hooks that can be attached anywhere on the mesh outer layer, eliminating the need for additional loop components and enhancing breathability while preventing skin irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hook-and-loop fasteners are used for easier donning, then the garment can be wrapped around and fixed to apply compression force, but the breathability is considerably reduced due to the additional loop compatible layer
Solution Approach 1:
The invention extracts the loop component from the fastening system, eliminating the need for an additional loop-compatible layer on the outer surface. Only the essential hook component is integrated into the compression garment's spacer fabric, allowing the outer layer to maintain its mesh structure and breathability while still providing effective fastening capability.
Solution Approach 2:
The hook component is integrated locally into the spacer fabric at specific fastening positions rather than requiring a comprehensive loop-compatible layer across the entire outer surface. This localized approach allows the majority of the garment to maintain its original breathable mesh structure while providing fastening functionality where needed.
2Reliability
If a loop compatible layer is added on the whole outer surface to accommodate hook-and-loop fasteners, then the fastening can be achieved, but the comfort to the wearer is reduced
Solution Approach 1:
The loop component is removed from the system entirely, eliminating the uncomfortable additional layer on the outer surface. The hook component alone is integrated into the spacer fabric, providing reliable fastening without compromising wearer comfort through excessive material layers or altered fabric texture on the outer surface.
3Reliability
If microscopic hooks are used in hook-and-loop fasteners, then fastening can be achieved, but lint can be trapped between hooks and make the fastener inoperable
Solution Approach 1:
The macroscopic hook is nested within the mesh structure of the spacer fabric, with the hook component integrated into the openwork knit pattern. This nesting approach allows the hook to function effectively while the mesh structure prevents lint accumulation that would occur with traditional microscopic hook-and-loop systems.

AI summary
A compression garment includes a spacer fabric part (1) with an inner layer (2) and an outer layer. The compression garment further includes a closing part (4) with at least one macroscopic hook (5). If a user dons the compression garment, the spacer fabric part (1) and/or the closing part (4) has to be stretched to generate the compression force and the stretching is maintained by attaching the closing part (4) to the spacer fabric part (1) by hooking the at least one macroscopic hook (5) into the mesh of the outer layer of the spacer fabric part (1).
