Knee Pad Tool Pockets for Roofers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for carrying tools while kneeling, such as tool belts and work pants with pockets, are cumbersome, lead to fatigue and accessibility issues, and require manual movement of tools or mats, which can result in inefficiency and risk of losing tools.
Innovation Solution
Integrated tool or accessory carriers within knee pads that are independently removable and designed to securely hold tools or accessories, with pockets that remain accessible when kneeling or standing, allowing for efficient tool management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tool belts are used to carry tools, then tools can be transported, but it leads to fatigue and back pain and makes tool accessibility difficult when kneeling
Solution Approach 1:
The patent combines the tool carrying function with the knee pad by integrating tool pockets directly into the knee pad structure. This merging eliminates the need for separate tool belts and allows tools to be carried close to the body without causing fatigue or back pain, while remaining easily accessible when the worker is kneeling.
Solution Approach 2:
The patent transitions from horizontal tool carrying (waist-level tool belt) to vertical tool carrying (knee-level pockets). By changing the spatial dimension from horizontal to vertical placement, the tools become accessible while the worker is in a kneeling position, eliminating the need to reach back to a waist-level belt.
2Ease of operation
If work pants with built-in pockets are used, then tools can be carried, but the pockets are not easily accessible when kneeling and tools cannot be independently removed
Solution Approach 1:
The patent segments the tool carrying function from the work pants by placing tool pockets directly on the knee pads. This segmentation allows the tools to be carried conveniently while kneeling, and the knee pads with tool pockets can be independently removed from the work pants, providing flexibility in tool removal without compromising accessibility.
3Ease of operation
If separate tool boxes or mats are used, then tools can be carried, but they require manual movement each time the worker moves and risk losing tools
Solution Approach 1:
The patent merges the tool carrying function with the knee pad assembly, creating an integrated system where tools are carried on the knee pads themselves. This eliminates the need for separate tool boxes or mats that would require manual movement, thereby improving productivity by keeping tools stationary relative to the worker's position.
4Ease of manufacture
If knee pads without tool pockets are used, then knee protection is provided, but tools must be carried separately on tool belts or in pockets
Solution Approach 1:
The patent combines the knee pad and tool pocket into a single integrated unit. By merging these two separate functions into one device, the patent eliminates the need for separate tool belts or pockets, thereby reducing overall device complexity while maintaining knee protection functionality.

AI summary
A knee pad assembly for work tasks requiring kneeling, including a knee pad, a method of attaching the knee pad to a user's leg, and a tool or accessory receiver attached or integrated to the knee pad. The tool or accessory receiver provides easy and convenient access to tools or accessories at the knee of the worker.
