Adjustable Loop Knee Pad Attachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Knee pads often fail to stay properly positioned over the knees, frequently moving or sliding down during physical labor, which can lead to chronic pain and injury due to inadequate securing mechanisms.
Innovation Solution
A knee pad holding mechanism featuring two lengths of fabric material secured to the pantleg, forming loops that allow for adjustable placement and secure attachment of fastening straps, minimizing movement and providing stability over the knee area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple knee pad attachment method is used, then the device complexity is reduced, but the knee pad cannot stay properly positioned and slides down during movement
Solution Approach 1:
The patent implements multiple adjustable loops at different heights on the pantleg, allowing the fastening strap to be dynamically repositioned. This enables the knee pad to maintain proper positioning as the user moves and shifts on their knees, resolving the contradiction between simple attachment and reliable positioning.
Solution Approach 2:
The attachment mechanism is segmented into multiple discrete loops distributed vertically along the pantleg. This segmentation allows selective engagement at different heights, providing both simplicity in individual loop design and reliability through multiple engagement options.
2Reliability
If a fixed positioning mechanism is used, then the knee pad remains stable, but the user cannot adjust the vertical location to achieve proper positioning
Solution Approach 1:
The system transitions from fixed positioning to dynamic adjustability by providing multiple loops at different vertical locations. The user can select and adjust the strap engagement point to achieve proper knee pad positioning, while the fastening mechanism itself remains stable once engaged.
Solution Approach 2:
The multiple loops serve universal positioning function, allowing the same fastening strap mechanism to accommodate different vertical positions. This multi-functional design provides both adjustability and stability without requiring different mechanisms for each function.
3Adaptability or versatility
If multiple adjustment options are provided, then the user can achieve proper positioning, but the device complexity increases
Solution Approach 1:
The complexity is managed through segmentation into simple, identical loop units distributed along the pantleg. Each loop is a simple fabric component, and the overall system achieves adjustability through the arrangement of these simple segments rather than through complex individual components.
Solution Approach 2:
The loops are constructed from flexible fabric material that integrates with the pantleg, avoiding rigid or complex mechanical adjustment mechanisms. This flexible implementation provides adjustability while maintaining simplicity in the overall device structure.

AI summary
A knee pad holding mechanism for holding a knee pad over the knee region of a pantleg having a first length of fabric material and a second length of fabric material operatively attached to a pantleg on opposite sides of the knee region, each length of material forming a plurality of loops for receiving a strap associated with the knee pad. The plurality of loops associated with the first and second lengths of material are arranged in opposed relationship to each other and allow a user greater flexibility to adjust the vertical location of a knee pad relative to the user's knee. The plurality of loops can be individually formed on opposite sides of the knee region, or they can be formed using any number of a plurality of sections.
