Angled Knitted Cuff for Anatomical Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressive knitted parts, such as stockings, often fail to provide a consistent anatomical fit, leading to discomfort, increased wrinkle formation, and higher manufacturing costs due to additional sewing steps.
Innovation Solution
The knitted part consists of a basic trick section and a fringed section, where the fringed section is angled relative to the basic trick section, changing the knitting direction to improve anatomical adaptation and reduce manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the base knit is knitted continuously in a tubular shape without anatomical adaptation, then the manufacturing process is simple, but the fit to the extremity is poor and wrinkle formation increases
Solution Approach 1:
The knitted fabric is divided into multiple knit sections with different knitting patterns (plain knit, purl knit, float knit) arranged in zones. Each zone is knitted with specific stitch patterns to adapt to different anatomical requirements of the extremity, improving fit without complicating the overall continuous knitting process
Solution Approach 2:
Different knit sections are assigned to different zones of the fabric to provide local adaptation to anatomical features. The plain knit sections provide compression, while purl and float knit sections provide relief and adaptation to contours, creating locally optimized fit characteristics
2Manufacturing precision
If the knitting structure is modified in areas requiring increased adaptation, then the anatomical fit is improved, but the knitted fabric properties deteriorate
Solution Approach 1:
The knitting structure is made dynamic by alternating between different knit patterns (plain, purl, float) in a systematic sequence. This allows the fabric to adapt to anatomical variations while maintaining overall structural integrity and consistent mechanical properties through the rhythmic repetition of patterns
Solution Approach 2:
The knitted fabric is produced in a continuous knitting process without interruption or breaking of the knitting action. The transition between different knit sections is achieved continuously within the same knitting cycle, maintaining fabric property consistency while providing anatomical adaptation
3Stability of the object's composition
If waistband sections are added to the circular knit, then the garment stability is improved, but the wearing comfort deteriorates due to incorrect positioning on the limb
Solution Approach 1:
The waistband sections are positioned asymmetrically on the circular knit fabric, with different locations for upper and lower waistbands. This asymmetric arrangement allows the waistbands to be correctly positioned on the anatomical landmarks of the extremity (such as above and below the knee), improving both stability and wearing comfort
4Ease of operation
If multiple differently knitted areas are incorporated to create anatomical shape, then the wearing comfort is improved, but the manufacturing complexity increases
Solution Approach 1:
The knitting machine uses universal stitch pattern selections that can be programmed to create multiple different knit sections (plain, purl, float) within a single continuous knitting process. This multi-functionality allows anatomical adaptation without requiring separate knitting operations or complex manual interventions
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
This design enhances the fit of the knitted part by providing an anatomically shaped garment with improved wearing comfort and reduced wrinkle formation, while also lowering production costs through a single knitting process.
Implementation Method 1
an elastic weft thread is inserted into the knitted stitches in every row or every Xth row
Implementation Method 2
The applied pressure prevents increasing swelling of the limbs, improves the removal of venous blood and lymph, and increases blood supply
