Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for disinfecting wounds on clipped tree branches are slow and laborious, as they require applying a healing agent one by one, significantly reducing clip efficiency.
Innovation Solution
The development of blade heatable electric scissors with a heating sheet and temperature sensor, connected to a control circuit, which heats the blade to a high temperature during shearing, enabling simultaneous shearing and disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a healing agent is applied to wounds on clipped branches one by one, then the trees are prevented from being infected with bacteria and getting rotten, but the clip efficiency is severely reduced
Solution Approach 1:
The patent combines the shearing function and disinfection function into a single integrated tool. The heating blade simultaneously performs cutting and high-temperature disinfection, eliminating the need for separate disinfection steps and thereby maintaining both reliability of disinfection and productivity of clipping operations
Solution Approach 2:
The electric scissors blade is designed to perform multiple functions: mechanical shearing of branches and thermal disinfection of wounds. By integrating a heating element into the blade, the tool becomes universal, capable of both cutting and sterilizing in one operation, thus resolving the contradiction between disinfection effectiveness and clip efficiency
2Productivity
If the blade is heated to high temperature for disinfection, then the disinfection efficiency is improved, but the energy consumption increases
Solution Approach 1:
The blade is preheated to the required disinfection temperature before actual shearing operations begin. This preliminary heating ensures that when the blade is used for cutting, the disinfection function is already active, eliminating the need for separate post-cutting disinfection and reducing total energy consumption while maintaining high disinfection efficiency
Solution Approach 2:
The heating element maintains the blade at a constant high temperature throughout the shearing process. Rather than heating after each cut or before each cut, the continuous heating ensures the blade remains at optimal disinfection temperature for all cutting operations, improving disinfection efficiency while avoiding repeated energy input cycles

AI summary
The present invention discloses blade heatable electric scissors (1) and a control method. The electric scissors (1) include a scissors body (21), wherein a first blade (2) is arranged at a front end of the scissors body (21), a heating sheet (4) and a temperature sensor (5) are arranged on the first blade (2), and the heating sheet (4) and the temperature sensor (5) are connected to a heating sheet (4) drive circuit and a blade temperature detection circuit through a conduction cable (20) respectively. Compared with the prior art, the present invention arranges the heating sheet (4) on the shearing blade, such that a cut may be subjected to high-temperature disinfection while a branch is clipped. Meanwhile, the present invention may adjust a preheating temperature reference and a shearing high temperature reference according to a latitude difference, an environment temperature difference, and a variety difference of sheared plants. According to the present invention, the blade is further set to be heated to a high temperature upon shearing, thereby greatly saving on electric energy consumption, and disinfection and sterilization operation on the cut is completed as well while a shearing action is completed by the present invention, thereby greatly improving efficiency.
