Self-Adjusting Joint Protector Pad with Torso Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional joint pads cause discomfort and irritation due to tight straps that impede circulation and require frequent repositioning, leading to debilitating effects during prolonged use.
Innovation Solution
A joint protector system with straps extending from opposite sides of the pad, attaching to the foot and torso, allowing automatic alignment with the joint during flexion and straightening, eliminating the need for manual repositioning and reducing strap tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If straps are pulled tightly around the limb to secure the pad in position, then the pad remains stable and does not drift during movement, but this causes discomfort, pinching, squeezing, and may impede circulation through the limb
Solution Approach 1:
The patent removes the harmful wrapping straps that encircle the limb from the design. Instead, it uses a single strap that attaches to the pad at one location and extends to the torso, eliminating the need for straps to wrap around and constrict the limb while still maintaining pad stability through the self-adjusting mechanism.
Solution Approach 2:
The pad incorporates a self-adjusting mechanism with a biasing element that automatically maintains proper alignment with the joint. The biasing element provides continuous force to keep the pad in the correct position without requiring tight straps, allowing the system to self-regulate and maintain stability without external constriction.
2Stability of the object's composition
If straps are wrapped tightly around the limb to prevent pad movement, then the pad stays in position, but this causes skin irritation and chafing that worsens over prolonged use
Solution Approach 1:
The patent eliminates the multiple wrapping straps that contact and rub against the skin. The single strap configuration attached to the torso minimizes contact with the limb skin, and the self-adjusting mechanism eliminates the need for tight wrapping, thereby preventing the skin irritation and chafing that occur with conventional designs during prolonged use.
Solution Approach 2:
The self-adjusting mechanism with the biasing element dynamically maintains pad alignment as the joint moves through different positions. This dynamic adjustment ensures the pad remains properly positioned without requiring constant tight strapping, reducing friction and irritation against the skin during movement and prolonged wear.
3Ease of operation
If conventional pads are secured with straps, then initial positioning is achieved, but the pads shift out of position over time during use and require manual repositioning
Solution Approach 1:
The pad incorporates a self-adjusting mechanism with a biasing element that automatically maintains proper alignment with the joint throughout use. As the joint moves, the biasing element continuously adjusts the pad position, eliminating the need for manual repositioning and saving time during prolonged activities.
Solution Approach 2:
The self-adjusting mechanism dynamically responds to joint movement, automatically maintaining optimal pad alignment. This dynamic adjustment capability ensures the pad remains in the correct position throughout various ranges of motion without requiring the wearer to stop and manually reposition it, addressing the time loss issue.
4Object-affected harmful factors
If clips are used to attach the pad to clothing, then the pad can be secured without tight straps, but the clips easily disengage when the pad is hit or impacted
Solution Approach 1:
The patent combines the attachment function with the structural support function by using a single strap that extends from the pad to the torso. This integrated approach provides both secure attachment and reliable retention under impact, eliminating the need for separate clips that can easily disengage while maintaining reduced strap tension on the limb.
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 system provides continuous protection without irritation or circulation issues, maintaining proper alignment and reducing the need for manual adjustments, allowing for increased mobility and comfort during extended use.
Implementation Method 1
the straps are made of a resilient material such that, when the joint is straightened, the straps automatically pull the joint protector pad back into spaced aligned relation to the joint

AI summary
A self-adjusting system for joint protection comprising a joint protector pad aligned relative to a joint and disposable between an operative orientation and a spaced orientation in relation thereto. A first attachment assembly of at least one elongate strap connects the joint protector to a foot or hand of the wearer, and a second attachment assembly of an elongate strap(s) connecting the joint protector to a point near the torso of the wearer, such as a waistband or belt. In a spaced orientation when the joint is straight, the joint protector is spaced apart from the joint so as not to impede movement. In an operative orientation when the joint is flexed, the joint protector at least partially covers the joint, supporting and protecting it from the underlying surface. The strap(s) ensure the joint protector is automatically properly aligned in moving between the spaced and operative orientation.
