Tool Arm Support Attachment for Landscaping Fatigue Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional landscaping tools, such as string trimmers, often cause user fatigue and back pain due to the need for users to hold the tool with both hands, leading to prolonged strain on the arms and back.
Innovation Solution
An attachment device with an adjustable shaft and a cuff that secures to the tool, providing additional support and comfort by allowing the user to receive the arm within an elongated channel, thereby reducing strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user holds the tool with both hands, then the tool can be controlled effectively, but user fatigue and back pain increase
Solution Approach 1:
The attachment device acts as an intermediary between the user and the tool. The cuff receives the user's arm and the shaft transmits support forces, mediating the interaction to reduce direct strain on the user's hands and back while maintaining tool control capability.
Solution Approach 2:
The invention adds a new dimensional element of support by introducing the attachment device with its shaft and cuff structure. This creates an additional support dimension that redistributes the load from the user's hands and back to the attachment device, reducing fatigue and pain.
2Ease of operation
If an attachment device with shaft and cuff is added, then user support and comfort improve, but device complexity increases
Solution Approach 1:
The attachment device is segmented into distinct functional components: the cuff that receives the arm, the shaft that provides structural support and transmission, and the connection mechanism to the tool. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The attachment device incorporates adjustable elements that allow dynamic adaptation to different user needs and tool configurations. The adjustability features enable the device to maintain optimal support characteristics while accommodating variations in arm size and tool type, reducing overall system complexity through standardized adjustable mechanisms.

AI summary
An arm support tool attachment includes a shaft extending from a first end to a second end; a clamp positioned at the second end of the shaft, the clamp to removably secure to a handle portion of a tool; and a cuff having an elongated channel to receive and support a user’s arm, the cuff attached to the shaft at the first end; the shaft extends the cuff away from the handle portion of the tool such that the cuff provides user support.
