Flat-Knitted Pants Seat With Offset Gussets for Anatomical Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compression pants with flat-knitted material for the seat area often fail to provide an optimal anatomical fit and adequate compression, leading to discomfort and less effective lymphologic treatment.
Innovation Solution
A flat-knitted material design featuring two adjacent 3-dimensionally curved parts, each formed by multiple knitted gussets that are offset from each other, creating a hemispherical shape that closely conforms to the anatomy of the buttocks, while maintaining compressive properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the flat-knitted material is knitted with a 3-dimensional curvature to form a hemispherical shape, then the anatomical fit is improved, but the compressive fit in the buttocks area is insufficient
Solution Approach 1:
The seat section is divided into multiple knitted gussets (first gusset, second gusset, third gusset, fourth gusset) arranged in a specific pattern. These gussets create distinct compression zones that maintain compressive fit while forming the hemispherical shape, resolving the contradiction between shape and compression reliability.
Solution Approach 2:
Different regions of the flat-knitted material are assigned different functions: the gussets provide compression while the overall curvature provides anatomical fit. The interknitted elastic weft yarn is distributed throughout to ensure compressive properties are maintained in all areas, especially in the buttocks region.
2Adaptability or versatility
If the flat-knitted material comprises two adjacent 3-dimensionally curved parts, then the anatomical adaptation is significantly improved, but the device complexity increases
Solution Approach 1:
The seat section is segmented into multiple gussets (first, second, third, fourth gussets) that are systematically arranged to form two adjacent 3-dimensionally curved parts. This segmentation allows the complex anatomical adaptation to be achieved through repeated modular units rather than a single complex structure.
Solution Approach 2:
Multiple gussets are combined in a specific arrangement where the first and second gussets form one curved part and the third and fourth gussets form another curved part. This merging of simpler elements creates the complex anatomical adaptation needed for the buttocks region.
3Reliability
If the gussets are knitted to be offset in the transverse direction, then the compressive properties are maintained, but the manufacturing precision requirements increase
Solution Approach 1:
The seat section is divided into multiple discrete gussets arranged in rows, with each gusset positioned at a specific offset in the transverse direction. This segmentation into manageable units makes the offset alignment more controllable during manufacturing while maintaining compressive properties.
Solution Approach 2:
The gussets are deliberately offset in the transverse direction to create an asymmetric pattern that maintains compressive properties. This asymmetric arrangement is systematically implemented through the knitting process, transforming a precision challenge into a controlled design feature.

Function Achieved in This Case
The design significantly enhances the fit and comfort of the compression pant by accommodating each half of the buttocks separately, allowing for more effective compression and improved lymphologic treatment.
