Four-Needle-Bed Compression Ski Suit With Regional Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression ski suits fail to account for the varying sweat volumes and pressure requirements of different body parts, leading to poor wearing experience and discomfort.
Innovation Solution
A compression ski suit knitted by four needle beds with functional structures tailored to specific body parts, including partially convex, pore, pleated, and jacquard structures, integrated with pressure and moisture management features, and a seamless knitting method using a flat knitting machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single knitted structure is used throughout the compression ski suit, then the manufacturing process is simplified, but the wearing comfort and functional adaptability to different body parts deteriorates
Solution Approach 1:
The patent applies local quality by implementing different knitted structures in different regions of the compression ski suit. Specifically, the top includes a first knitted structure in the shoulder region, a second knitted structure in the upper arm region, a third knitted structure in the elbow region, and additional structures in the chest and back regions. The trousers include corresponding regional structures for the outer thigh, inner thigh, knee, and rear shank areas. This regional differentiation allows each body part to receive the specific functional characteristics it needs while maintaining overall manufacturing coherence through a single integrated knitting process.
2Strength
If high compression pressure is applied uniformly across all body parts, then muscle support is improved, but wearing comfort and moisture management deteriorates
Solution Approach 1:
The patent implements local quality in pressure distribution by designing different knitted structures for different body regions based on their specific functional requirements. The chest part includes a fourth knitted structure, a fifth knitted structure, and a sixth knitted structure arranged from the chest toward the body side, creating a pressure gradient that provides stronger compression where needed while maintaining comfort in other areas. Similarly, the back part has a seventh knitted structure with different characteristics. This regional pressure differentiation ensures adequate muscle support while preventing discomfort from excessive uniform compression.
Solution Approach 2:
The patent applies porous materials principle through the incorporation of pore structures in various knitted regions. The second knitted structure in the upper arm region is described as a pore structure with an inverted V-shape pattern, and the seventh knitted structure in the back part is also a pore structure. These porous structures facilitate air circulation and moisture evaporation, enhancing wearing comfort and thermal regulation while maintaining the compression function in high-support areas.
3Ease of operation
If seamless integral knitting is used, then wearing comfort and fit are improved, but manufacturing complexity and labor cost increase
Solution Approach 1:
The patent applies the merging principle by integrating multiple functional knitted structures into a single seamless garment through one continuous knitting process. The top is formed as an integral piece that combines the first, second, third, fourth, fifth, sixth, and seventh knitted structures without seams or joints. Similarly, the trousers are knitted as a single integrated piece with all required regional structures. This merging approach eliminates the need for separate knitting of different sections and subsequent assembly, thereby maintaining wearing comfort and fit while actually reducing manufacturing complexity compared to multi-piece construction.

AI summary
A compression ski suit includes a top and trousers. The top is integrally knitted, and corresponding functional knitted structures are arranged on shoulder parts, upper arm parts, elbow parts, a chest part and a back part of the top according to functional divisions of human body parts. The trousers are integrally knitted, and corresponding functional knitted structures are arranged on outer thigh parts, inner thigh parts, knee parts and rear shank parts of the trousers according to the functional divisions of the human body parts.
