Electric Scissors Directional Trigger for Auxiliary Blade Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric scissors designs for pruning and cutting operations face complexity in auxiliary operations, with either complicating existing manipulating sections or increasing the number of components and manufacturing costs when adding separate sub-triggers.
Innovation Solution
The design incorporates a pair of blade sections with a single manipulating member having a first section for opening and closing operations and a second section for auxiliary operations, where the manipulating member's movement direction determines the operation, utilizing a sensor to detect the direction of manipulation and perform either opening/closing or auxiliary functions without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate sub-trigger is provided for auxiliary operations, then the auxiliary operation can be performed without complicated manipulations, but the structure of the manipulating section becomes complicated and the number of components increases
Solution Approach 1:
The single manipulating member (trigger) is designed to perform multiple functions: it can perform both the main cutting operation and auxiliary operations such as adjusting the opening angle of the blade. By making the trigger universal, the patent eliminates the need for a separate sub-trigger, thus simplifying the manipulating section structure while maintaining ease of operation for auxiliary functions
2Ease of operation
If a separate sub-trigger is provided for auxiliary operations, then the auxiliary operation can be performed without complicated manipulations, but the manufacturing cost increases
Solution Approach 1:
The patent employs a single manipulating member that serves multiple purposes, including both main cutting control and auxiliary operations like blade opening angle adjustment. This universal design reduces the total number of components that need to be manufactured and assembled, thereby lowering manufacturing costs while still providing easy-to-perform auxiliary operations
3Device complexity
If the existing manipulating section is used for auxiliary operations through predetermined procedures, then the number of components remains the same, but the manipulation becomes complicated and hard to understand
Solution Approach 1:
The manipulating member is divided into distinct functional sections: a main trigger portion for cutting operations and a sub-trigger portion for auxiliary operations. This segmentation allows each section to be optimized for its specific function while being part of a unified structure, making the operations intuitive and easy to understand without requiring complicated procedures
4Device complexity
If the existing manipulating section is used for auxiliary operations through predetermined procedures, then the number of components remains the same, but the operation takes more time
Solution Approach 1:
By segmenting the manipulating member into distinct functional areas (main trigger and sub-trigger), the patent enables users to perform auxiliary operations directly without needing to follow complex multi-step procedures. This segmentation allows for quick, intuitive access to different functions, reducing the time required for manipulation while maintaining a simple component structure

AI summary
Electric scissors includes a pair of blade sections and a manipulating member. The pair of blade sections is capable of being opened and closed. The manipulating member has a first manipulating section and a second manipulating section which are provided to face each other. The first manipulating section performs opening and closing operation of the blade sections. The second manipulating section performs an auxiliary operation which is different from the opening and closing operation. When the first manipulating section is manipulated in a predetermined direction, the opening and closing operation is performed. When the second manipulating section is manipulated in a direction different from the predetermined direction, the auxiliary operation is performed.
