Lopper Clamping Jaw for Branch Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand loppers for trimming branches are hazardous due to falling debris and require uncomfortable labor to collect scattered refuse, as they do not effectively manage the cutting and collection of branches.
Innovation Solution
A lopper device with a fixed jaw attached to the cutting edge and a spring-loaded moving grip jaw that clamps the cut branch, allowing for secure holding and easy transport of the cut refuse, reducing the need for repeated bending and minimizing scattered debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional loppers are used to cut branches overhead, then cutting capability is achieved, but falling debris and scattered refuse create safety hazards and require uncomfortable labor to collect
Solution Approach 1:
The patent combines the cutting function with a collection function by integrating a container onto the lopper handles. This merging of functions allows the user to cut and collect debris in a single operation, eliminating the separate collection step that causes repeated bending and improving both safety and labor comfort.
Solution Approach 2:
The container acts as an intermediary element between the cutting blades and the ground. It captures debris at the point of cutting, preventing it from falling to the ground and creating scattered refuse. This intermediary solution directly addresses the safety hazard and eliminates the need for uncomfortable collection labor.
2Productivity
If traditional loppers cut branches, then trimming is accomplished, but debris scatters and must be collected through repeated bending
Solution Approach 1:
The patent merges the cutting operation with the collection operation into a single integrated process. The container attached to the lopper handles captures debris immediately upon cutting, eliminating the need for a separate collection step. This directly improves productivity by combining two previously separate tasks and reduces time loss by eliminating the repeated bending required for collection.
3Ease of operation
If loppers are used at arm's length for trimming, then accessibility to branches is improved, but scattered refuse is generated that requires collection
Solution Approach 1:
The container serves as an intermediary that captures debris at the cutting point when working at arm's length. This allows the user to maintain the advantageous arm's-length positioning for accessibility while the container prevents debris from scattering, directly resolving the contradiction between ease of operation and harmful factors.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enhances safety by preventing falling debris and reduces labor by allowing users to easily collect and transport cut branches without scattering, improving the efficiency of branch trimming operations.

AI summary
Disclosed are shears are used for trimming bushes, trees, and brush. The loppers have the cutting blade which performs the cutting action and a counter edge for the cutting blade to work in conjunction. These loppers also have the addition of clamping jaws which will hold the severed limb. A user amputates a tree limb and the severed or orphaned limb falls helplessly to the ground, but these loppers clamp onto that limb when the cutting operation is performed. After the cut is made, the user can move the limb to a specific location, then decompresses the loppers and drop the limb as intended.
