Knee Pad Strap Alignment with Curved Ears and Detents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knee pad devices fail to maintain proper alignment, leading to discomfort and reduced effectiveness in protecting the knee and ankle areas during prolonged kneeling tasks.
Innovation Solution
The knee pad features curved strap ears with détentes that align and center the support frame strap on the leg, ensuring the device remains properly positioned and secured, utilizing a cushioning material for impact absorption and including a liner for protection from debris and sweat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional knee pad devices are used, then basic knee and ankle protection is provided, but the device fails to maintain proper alignment and shifts off to one side
Solution Approach 1:
The strap ears are curved to conform to the contour of the user's leg, allowing the strap to wrap around the leg more effectively. This curvature enables the détentes to engage properly with the strap, maintaining alignment stability while accommodating the natural shape of the leg for ease of operation.
Solution Approach 2:
The détentes act as intermediary elements between the strap ears and the support-frame strap. These detentes receive and secure the strap, serving as a mediating mechanism that prevents the strap from shifting while maintaining proper alignment and comfort during use.
2Reliability
If the support frame is strapped to the leg, then the knee pad is secured to the user, but the strap becomes misaligned and uncomfortable
Solution Approach 1:
The curved shape of the strap ears allows them to wrap around the leg's contour, maintaining securing effectiveness while ensuring the strap remains properly aligned with the leg's anatomy, preventing discomfort and misalignment during use.
Solution Approach 2:
The détentes automatically receive and secure the support-frame strap through their engagement mechanism, providing self-aligning functionality that maintains proper strap positioning without requiring additional adjustment or intervention from the user.

AI summary
A knee pad with a support frame, a pad, and a boot. The pad is assembled on the support frame to provide a cushioning surface between the support frame and the wearer's leg. The pad has ears in the knee section and in the ankle section, which serve to maintain the support frame and pad in proper alignment on the leg. The boot provides a non-slip, non-marring surface against the floor, when the wearer is working in a kneeling position. A moisture-absorbent liner, which is easily removed for cleaning or replaceable, may also be fitted on top of the pad, to provide an absorbent layer between the pad and the wearer's leg.
