Pivoting Razor Blade Holder for Cutting Machine Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting blade holders require time-consuming rotational and axial adjustments to achieve optimal cutting position, disrupting the cutting process and complicating the replacement of worn blades.
Innovation Solution
A pivotally mounted cutting blade holder with a base and a carrier that allows for simultaneous adjustment of the cutting blade's immersion depth and angle of attack via a pivoting mechanism, facilitated by a lever system and optional magnetic fixation, enabling a single operation to achieve the desired cutting position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional cutting blade holders with separate rotational and axial adjustment mechanisms are used, then the cutting blade can be positioned in the cutting area, but the adjustment process becomes time-consuming and disrupts the cutting process
Solution Approach 1:
The patent combines multiple adjustment functions (rotational and axial positioning) into a single pivoting movement of the carrier. The pivot point is positioned at the cutting blade tip, allowing one operation to simultaneously achieve both rotational angle and immersion depth adjustment, eliminating the need for separate adjustment mechanisms and reducing adjustment time while maintaining positioning accuracy
2Measurement precision
If multiple adjustment operations (rotary and linear) are required to position the cutting blade, then the desired cutting position can be achieved, but the device complexity increases
Solution Approach 1:
The patent merges multiple adjustment mechanisms into a single pivoting carrier mechanism. The carrier rotates about a pivot point located at the cutting blade tip, allowing simultaneous control of both rotational angle and axial immersion depth through one degree of freedom, thereby simplifying the overall device structure while maintaining precise positioning capability
Solution Approach 2:
The invention transforms a two-dimensional adjustment problem (separate rotational and axial adjustments) into a one-dimensional solution by positioning the pivot point at the cutting blade tip. This geometric arrangement allows a single rotational movement to produce coupled changes in both angular orientation and axial position, effectively reducing the number of independent adjustment mechanisms needed
3Measurement precision
If the cutting blade holder requires multiple adjustment operations, then positioning accuracy can be achieved, but the ease of operation decreases
Solution Approach 1:
The patent combines multiple adjustment operations into a single intuitive pivoting action. The operator simply rotates the carrier about the pivot point at the blade tip, and both the rotational angle and immersion depth are automatically adjusted simultaneously, making the operation as easy as a single rotational movement while maintaining precise positioning
4Reliability
If traditional cutting blade holders are used, then the cutting blade can be replaced when worn, but the replacement process is time-consuming and interrupts the cutting process
Solution Approach 1:
The patent integrates the positioning and securing functions into a single carrier structure that pivots about the blade tip. When a blade needs replacement, the carrier can be quickly pivoted to access the blade, the blade removed and replaced, and then the carrier returned to position in one smooth operation, minimizing interruption to the cutting process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Streamlines the adjustment process, reducing downtime and improving the efficiency of blade replacement and alignment, allowing for optimal cutting performance without multiple adjustment operations.
Implementation Method 1
A magnet is optionally designated 6, which ensures that the cutting blade, in particular the razor blade 7, is pre-fixed in the receptacle (the receptacle area 4) when it is inserted there
Implementation Method 2
By means of a lever 5, the carrier 3 can be pivoted relative to the base 2 and can also be fixed
