Shearing Device with Integrated Pincer Posts for Secure Pruning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gardening tools, such as scissors and tweezers, fail to securely cut and prune delicate blossoms without damaging contiguous flowers or stems, and often result in severed blooms falling among other blossoms, causing bruising and damage to the plant.
Innovation Solution
A hand-operated, two-blade shearing device with pincer posts on each blade, allowing for secure pinching and holding of cut stems, preventing them from falling and minimizing disturbance to adjacent blossoms and leaves, featuring a pivot mechanism and handles for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional scissors or tweezers are used to cut delicate blossoms, then the cutting function is achieved, but the severed blossom falls among contiguous blossoms causing bruising and damage
Solution Approach 1:
The patent combines the cutting function (blades) with the gripping function (pincers) into a single integrated device. The pincers are operatively associated with the blades such that when the blades shear the blossom stem, the pincers simultaneously engage and secure the severed stem, preventing it from falling among contiguous blossoms. This merging of functions eliminates the need for separate retrieval tools and protects delicate plant tissue.
2Ease of operation
If fingers or tweezers are used to retrieve severed blossoms, then the blossom can be removed, but contiguous blossoms, leaves or stems are touched and bruised
Solution Approach 1:
The device merges the cutting and gripping functions into one operation. The pincers are positioned and dimensioned to secure the severed stem at the moment of cutting, allowing the entire blossom to be removed in a single motion without requiring manual retrieval that would contact and bruise remaining plant tissue.
Solution Approach 2:
The pincers act as an intermediary mechanism between the cutting action and the removal of the blossom. Instead of direct manual contact with delicate tissues, the pincers securely grasp the severed stem and serve as the interface for removing the blossom from the plant, eliminating harmful contact with contiguous blossoms.
3Ease of operation
If reaching into the plant body to retrieve severed stems, then the blossom can be removed, but thorny stems cause pain and frustration
Solution Approach 1:
By combining cutting and gripping functions, the device allows the blossom to be severed and secured in one continuous motion from the outside, eliminating the need to reach inside the plant structure where thorns are located.
Solution Approach 2:
The pincers serve as an intermediary that secures the blossom externally during the cutting process, allowing removal without inserting hands or fingers into the plant body where thorns are present, thereby preventing physical injury to the user.
4Reliability
If delicate blossoms are pruned from densely clustered stems, then the dying blossom can be removed, but the slightest disturbance damages other blossoms
Solution Approach 1:
The integration of cutting and gripping functions allows the operator to secure the target blossom during cutting, providing stability and control that reduces the precision required compared to manual methods. The pincers hold the blossom steady, preventing accidental contact with neighboring flowers while the blades make the cut.
