Adjustable Guide Plate for Precise Electric Cutting Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric cutting devices face difficulties in achieving precise cutting positions due to interference from guide plates, which restrict the cutting position based on the shape of the object being cut.
Innovation Solution
The electric cutting device features a guide plate that can be switched between two states: one where the guide plate's front end protrudes further than the cutting blades, and another where the cutting blades' front end protrudes further than the guide plate, allowing for adjustment to alleviate interference and achieve desired cutting positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide plate is provided to protect the cutting blades and guide the object, then the protection function and guiding function are improved, but the cutting position is restricted and interference with the object occurs
Solution Approach 1:
The guide plate is made movable relative to the cutting blades, allowing it to switch between a first position (protruding further) and a second position (retracted). This dynamic adjustment enables the guide plate to adapt to different cutting scenarios: providing protection and guidance when needed, and retracting to avoid interference with certain objects, thus resolving the contradiction between protection function and cutting position flexibility
2Ease of operation
If the guide plate protrudes further than the cutting blades, then the guiding function and protection function are enhanced, but the cutting position is restricted
Solution Approach 1:
The guide plate's position is made adjustable between protruding and retracted states relative to the cutting blades. When guiding function is needed, the guide plate protrudes to ease operation. When cutting position accuracy is required and the object shape would cause interference, the guide plate retracts to allow precise positioning, thus resolving the contradiction between ease of operation and cutting position accuracy

AI summary
An electric cutting device includes: a pair of cutting blades configured to clamp and cut an object; an electric motor configured to generate a driving force necessary for operating the cutting blades; and a guide plate formed with a recess configured to house the object in advance when the object is cut by the pair of cutting blades. The guide plate is configured to be switched between: a first state where a front end of the guide plate protrudes further than a front end of each cutting blade; and a second state where the front end of the cutting blade protrudes further than the front end of the guide plate.
