Hand-held Machine Rope Anchor via Handle Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held working machines, such as chain saws, lack a suitable connection receiving portion for anchoring ropes, which are necessary for safe operation at high places, as they can hinder work and pose safety risks due to accidental drops, and existing solutions are complex and costly.
Innovation Solution
Incorporating a connection receiving portion that utilizes an existing functional component, like a side handle or top handle, with a protrusion to retain the anchoring rope, preventing unnecessary movement and ensuring the rope does not interfere with operation, while maintaining a compact design and safety by directing the work tool downward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate connection receiving portion is added to the chain saw, then the anchoring rope can be securely connected, but the device complexity and cost increase
Solution Approach 1:
The handle, which is already a functional component for holding the chain saw, is designed to serve dual purposes: both as a gripping element and as a connection receiving portion for the anchoring rope. The protrusion on the handle allows the anchoring rope to be securely connected while maintaining the handle's primary function, thereby avoiding the need for a separate dedicated connection component and reducing overall device complexity.
2Reliability
If the connection receiving portion is added to the chain saw, then the anchoring rope can be securely connected, but the manufacturing cost increases
Solution Approach 1:
By making the handle serve as both a gripping element and a connection receiving portion, the patent eliminates the need to manufacture a separate component for rope connection. This multi-functional design reduces the total number of parts, simplifies assembly processes, and lowers manufacturing costs while maintaining reliable anchoring rope connection through the integrated protrusion feature.
3Ease of operation
If the anchoring rope is allowed to move freely, then it can be easily mounted and removed, but it may hinder the work and pose safety risks
Solution Approach 1:
The protrusion on the handle acts as an intermediary element that controls the movement of the anchoring rope. It allows the rope to be easily mounted and removed by guiding it into position, while simultaneously preventing excessive or unnecessary movement that could interfere with work or create safety hazards. The protrusion serves as a mediator between the rope and the handle, providing controlled interaction.
4Ease of operation
If the connection receiving portion is located at a position that allows easy mounting and removing, then the ease of operation improves, but the size of the working machine increases
Solution Approach 1:
The handle is designed to serve dual functions: as a gripping element and as a connection receiving portion. By integrating the rope connection capability into the existing handle structure rather than adding a separate component, the patent maintains ease of operation for mounting and removing the anchoring rope while avoiding any increase in the overall size of the working machine.

AI summary
Provided is a hand-held working machine, including a connection receiving portion (22) configured to connect an anchoring rope, which is configured to couple a machine body (2, 3) and an operator to each other, to the machine body (2, 3). The connection receiving portion (22) includes: an other-function portion provided to the machine body (2, 3) as a portion having other function or use; and a protrusion (23, 24, 25) configured to retain the anchoring rope at a predetermined position of the other-function portion.
