Compression Article with Weft Floats for Anti-Slip and Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compression articles, such as stockings and knee pads, often suffer from poor wearability and discomfort due to localized excess pressure, which existing designs fail to adequately address.
Innovation Solution
Incorporating a weft thread made of elastic material that forms floats on the internal face of the article, providing an anti-slip function by increasing the contact surface with the skin, and optionally offering additional functions like bacteriostatic, thermoregulation, moisture absorption, or moisturizing properties through the use of specific yarn materials and constructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression article uses a standard knit structure with elastic weft yarn, then the compression function is provided, but the article may not fit well and causes discomfort due to localized excess pressure
Solution Approach 1:
The patent applies local quality by creating distinct zones within the compression article: a first zone with standard knit structure for compression, and a second zone with weft floats for enhanced comfort and anti-slip properties. This allows different regions to have different functional characteristics, addressing both compression needs and comfort requirements simultaneously.
Solution Approach 2:
The compression article is segmented into functionally distinct zones: a first zone providing compression through standard elastic weft yarn insertion, and a second zone providing comfort and anti-slip functionality through weft floats. This segmentation allows each zone to optimize its specific function without compromising the other.
2Force
If the weft yarn is inserted in all stitches, then compression is provided uniformly, but the contact surface with skin is reduced and anti-slip function is diminished
Solution Approach 1:
The patent applies local quality by creating distinct zones within the compression article: a first zone with standard knit structure for compression, and a second zone with weft floats for enhanced comfort and anti-slip properties. This allows different regions to have different functional characteristics, addressing both compression needs and comfort requirements simultaneously.
Solution Approach 2:
Instead of inserting weft yarn in all stitches throughout the entire article, the patent uses partial action by inserting weft yarn in all stitches only in the first zone, while the second zone uses weft floats with selective stitch insertion. This partial differentiation optimizes both compression and contact surface area.
3Ease of operation
If the weft yarn forms floats in certain areas, then the contact surface with skin is increased for anti-slip function, but the compression uniformity may be affected
Solution Approach 1:
The compression article is segmented into functionally distinct zones: a first zone providing compression through standard elastic weft yarn insertion, and a second zone providing comfort and anti-slip functionality through weft floats. This segmentation allows each zone to optimize its specific function without compromising the other.

The patent applies local quality by creating distinct zones within the compression article: a first zone with standard knit structure for compression, and a second zone with weft floats for enhanced comfort and anti-slip properties. This allows different regions to have different functional characteristics, addressing both compression needs and comfort requirements simultaneously.
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 anti-slip function enhances comfort by preventing the article from sliding or rolling, while additional properties improve wearability and effectiveness, reducing pressure points and eliminating tourniquet effects, thereby increasing overall comfort and effectiveness of the compression.
Implementation Method 1
at least the weft yarn being made at least partly of elastic material
Implementation Method 2
the weft yarn... allows in particular to achieve an anti-slip function... the contact surface between the weft yarn and the patient's skin is increased

AI summary
The invention relates to a compression item (10) comprising a knitted fabric of at least one stitch yarn forming stitches and at least one weft yarn, and having an inner face for coming into contact with the skin of a user of said item. The weft yarn is arranged to as to perform the compression function. The item (10) comprises a region (32) in which the weft yarn is inserted into some of the stitches and passes over the inner face of other stitches so as to form floats on the inner face of said region (32). The weft yarn is arranged so as to perform an anti-slip function, as well as the compression function, by its nature and/or by a treatment of said weft yarn and by interaction with the skin of the user at least in said region (32).
