Clamping Ring Eyelet for Power Tool Safety Belt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held power tools lack a secure and ergonomic attachment mechanism for safety belts, which is essential for preventing accidents while operating at heights, and existing solutions require redesigning the tool's housing or are not compatible with existing side handles.
Innovation Solution
An assembly comprising a side handle with a clamping ring and an eyelet device that allows for the ergonomic attachment of a safety belt, where the eyelet device is attachable to the clamping ring without requiring additional connecting means, enabling secure fastening without altering the tool's housing and allowing retrofitting of existing side handles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the eyelet device is attached to the housing of the hand-held power tool, then the safety belt can be securely fastened, but the housing needs to be redesigned and redimensioned
Solution Approach 1:
The eyelet device is separated from the housing into an independent component that attaches to the clamping ring. This segmentation allows the housing to remain unchanged while providing secure fastening functionality through the separate eyelet device and clamping ring assembly.
Solution Approach 2:
The clamping ring serves as an intermediary element between the housing and the eyelet device. It provides a mounting surface for the eyelet device without requiring modifications to the housing structure, thus mediating between the need for secure fastening and the constraint of maintaining the original housing design.
2Adaptability or versatility
If the eyelet device is attached to existing side handles, then retrofitting is possible, but additional connecting means are required
Solution Approach 1:
The eyelet device is merged with the clamping ring through direct attachment, eliminating the need for separate connecting means. This combination achieves retrofitting capability while avoiding additional hardware complexity.
3Strength
If the clamping ring is dimensioned for high forces from the side handle, then existing forces are supported, but additional forces from the eyelet device require extra outlay
Solution Approach 1:
The clamping ring is designed to serve multiple functions: it provides the mounting surface for the side handle and simultaneously serves as the attachment point for the eyelet device. This multi-functionality allows it to handle forces from both the side handle and the eyelet device without requiring additional structural elements.
