Elbow Joint Supporter With X-Shaped Knitted Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elbow joint supporters fail to control full extension of the elbow joint and cannot effectively reduce strain on the biceps brachii tendon, leading to potential inflammation, and their manufacturing process is complex due to the use of resin or rubber for expansion and contraction inhibition sections.
Innovation Solution
An elbow joint supporter with a tubular knitted fabric design featuring a first anchor section, a second anchor section, and a supporting section knitted in an X-shape, providing enhanced stretch resistance in both circumferential and length directions to stabilize the elbow joint and reduce load on the biceps brachii tendon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resin or rubber is used for expansion and contraction inhibition sections, then the supporter can press the muscles, but the manufacturing process becomes complicated
Solution Approach 1:
The patent changes the material parameters by using knitted fabric with controlled elasticity instead of resin or rubber. The knitted fabric's inherent elastic properties allow it to press muscles during elbow extension while being integrally knitted, thus simplifying the manufacturing process by eliminating separate resin/rubber components and their associated printing processes
Solution Approach 2:
The patent uses a composite structure combining knitted fabric with elastic threads to create a material that has both the flexibility needed for comfort and the pressing force needed for muscle support. This composite knitted material replaces the traditional resin/rubber components while maintaining the muscle pressing function
2Ease of manufacture
If the expansion and contraction inhibition section extends only in the circumferential direction, then the manufacturing is simpler, but the elbow joint full extension cannot be controlled
Solution Approach 1:
The patent adds a longitudinal dimension to the expansion and contraction inhibition section by extending it along the length direction of the arm in addition to the circumferential direction. This creates a cross-shaped or grid-like pattern that provides control in both directions, preventing full elbow extension while maintaining manufacturing simplicity through integral knitting
Solution Approach 2:
The patent changes the geometric parameters of the inhibition section by extending it in both circumferential and longitudinal directions. This dimensional expansion of the inhibition section allows it to control elbow joint movement effectively without requiring complex assembly processes
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 supporter effectively limits elbow joint extension, reducing load on the olecranon and protecting the biceps brachii tendon, thereby alleviating pain and preventing inflammation, while simplifying the manufacturing process through knitted fabric construction.
Implementation Method 1
the stretch resistances of the first anchor section and the second anchor section in a circumferential direction of the tubular knitted fabric are larger than the stretch resistance of a base fabric section in the circumferential direction of the tubular knitted fabric. The stretch resistance of the supporting section in a length direction of the tubular knitted fabric is larger than the stretch resistance of the base fabric section in the length direction of the tubular knitted fabric

AI summary
Provided is an elbow joint supporter which can improve the stability of the elbow joint, reduce the strain on the elbow joint and reduce the load on the biceps brachii muscle tendon. The elbow joint supporter (10) comprises a first anchor section (2) formed by wrapping one end of a tubular knitted fabric around the wearer's upper arm to tighten said part with the tubular knitted fabric, a second anchor section (3) formed by wrapping the other end of the tubular knitted fabric around the wearer's forearm to tighten said part with the tubular knitted fabric, and a substantially X-shaped knitted supporting section (4) intersecting at the wearer's cubital fossa, two ends of the X-shaped knitted fabric each being joined to the first anchor section (2) and the other two ends of the X-shaped knitted fabric each being joined to the second anchor section (3); so as to support the wearer's elbow joint, wherein the stretch resistances, in the circumferential direction of the tubular knitted fabric, of the first anchor part (2) and the second anchor part (3) are larger than the stretch resistance, in the circumferential direction of the tubular knitted fabric, of a base fabric section (1), and the stretch resistance, in the length direction of the tubular knitted fabric, of the supporting section (4) is larger than the stretch resistance, in the length direction of the tubular knitted fabric, of the base fabric section (1).
