Detachable Saw and Pruner Assembly for Lopper Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tree pruning tools, such as loppers, pruners, and saws, are often misplaced or separated during and after use due to separate storage requirements, necessitating a solution to keep them together during both storage and use.
Innovation Solution
A tree pruning assembly featuring loppers with a detachable saw and pruner, utilizing connection devices like pins and slots, receiving pockets with resilient retaining clips, and quick release couplings to securely attach and detach the tools from the loppers, ensuring they remain together for use and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If loppers, pruners, and saws are stored separately, then each tool can be stored independently, but the tools may be misplaced or separated from one another
Solution Approach 1:
The patent combines multiple pruning tools (lopers, pruners, and saws) into a single integrated assembly. The pruners and saws are detachably connected to the loppers via connection devices, creating a unified tool system that prevents misplacement while maintaining individual tool functionality.
Solution Approach 2:
The patent segments the pruning tool system into detachable components (lopers, pruners, saws) that can be independently attached or detached. The connection devices enable each tool to be separately connected or disconnected while remaining part of the overall assembly when needed.
2Reliability
If pruners and saws are permanently attached to loppers, then tools remain together during storage and use, but the tools cannot be detached for separate use or storage
Solution Approach 1:
The patent employs dynamic connection devices that allow the pruners and saws to be easily attached to and detached from the loppers. This dynamic connection system provides both stability during use and flexibility for separate storage or use of individual tools.
Solution Approach 2:
The patent segments the pruning tool system into detachable components connected through specialized connection devices. These connection devices enable the tools to function as a unified assembly during use while allowing easy separation for individual storage or use.
3Reliability
If connection devices are added to attach pruners and saws to loppers, then tools can be kept together, but the device complexity increases
Solution Approach 1:
The patent extracts the connection function into separate, specialized connection devices that are distinct from the main tool bodies. These dedicated connection components simplify the overall design by isolating the attachment mechanism from the functional cutting tools.
Solution Approach 2:
The connection devices are designed to be universal, enabling multiple tools (pruners and saws) to be attached to the loppers using the same connection mechanism. This universality reduces complexity by using a single type of connection device for multiple attachment purposes.

AI summary
A tree pruning assembly is provided. The assembly comprises a lopper comprising two lopper handles pivotally connected to one another and a respective cutting blade arranged on an end of each of the lopper handles, a pruner adapted to be detachably connected to either one of the lopper handles, a saw adapted to be detachably connected to the other of the lopper handles, and a respective connection device for detachably connecting each of the pruner and the saw to a respective one of the lopper handles. The connection devices may be of identical construction so that the saw and pruner can each be connected to either of the lopper handles. A connection device for connecting a saw or pruner to a lopper handle is also encompassed by the present invention.
