Knee Brace With Adjustable Strap And Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knee braces are not positionally secure and do not allow for easy adjustment, leading to migration and inadequate support during use, which limits the range of motion and comfort for the wearer.
Innovation Solution
A knee brace design featuring a flexible strap with a handle and adjustable supports that extend circumferentially around the knee, allowing for secure positioning and easy re-adjustment to maintain support and comfort, using materials like elastic synthetic polymers and self-locking clasps for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional knee brace is designed to provide stability to the knee joint, then the knee joint stability is improved, but the positional security and adjustability of the brace deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the knee brace adjustable and movable rather than fixed. The brace includes multiple positioning holes and adjustable straps that allow the user to change the position and fit of the brace dynamically, resolving the contradiction between providing stable support and allowing positional adjustment.
2Stability of the object's composition
If a conventional knee brace is designed to resist excessive movement of the knee joint, then the knee joint stability is improved, but the range of motion of the subject deteriorates
Solution Approach 1:
The adjustable design allows the brace to adapt to different ranges of motion requirements. Users can modify the strap tension and positioning to maintain knee stability while preserving necessary movement freedom, thus resolving the contradiction between stability and range of motion.
3Ease of operation
If a conventional knee brace lacks positional security, then the ease of adjustment is improved, but the brace migration and inadequate support occur
Solution Approach 1:
The patent applies preliminary action by providing pre-configured positioning holes and attachment points that guide the user in securing the brace properly from the outset. The adjustable straps and multiple attachment options allow users to pre-adjust the brace to the correct position before use, preventing migration while maintaining ease of adjustment.
4Device complexity
If a conventional knee brace is designed without adjustment mechanisms, then the device complexity is reduced, but the positional security and comfort deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the adjustment system into discrete, simple components: multiple positioning holes, separate adjustable straps, and individual attachment points. This segmented approach maintains relative structural simplicity while enabling effective positional adjustment and security, resolving the contradiction between simplicity and reliability.
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 design effectively prevents migration of the knee brace, ensuring continuous support and comfort by allowing the wearer to easily adjust and secure the brace, maintaining a comfortable range of motion while preventing tripping hazards.
Implementation Method 1
The flexible strap is constructed of an elastic synthetic polymer

AI summary
A knee brace includes a body, a flexible strap, and a handle. The body is configured to support and circumferentially extend around a knee of a subject. The flexible strap includes a body end and a handle end, and the flexible strap is secured to the body at the body end; and a handle secured with the handle end of the flexible strap. The handle may include a rigid member with a gripping feature. The knee brace, or components thereof, may be constructed of an elastic synthetic polymer, such as nylon.
