Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media handling systems in machines like scanners, printers, and shredders face challenges in efficiently cutting media along different angles and paths, as existing solutions do not provide sufficient flexibility and precision in cutting-edge and tilt angles, affecting the cutting performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed cutting blade orientation is used, then the device structure is simple, but the cutting precision and flexibility for different angles are insufficient
Solution Approach 1:
The cutting blade is made dynamically adjustable through a fitting pin mechanism that allows the blade orientation to change based on operational requirements. The fitting pin can be positioned at different locations on the carriage, enabling dynamic adjustment of cutting-edge and tilt angles without complex mechanical reconfiguration systems.
Solution Approach 2:
The invention changes the geometric parameters of the cutting system by allowing the fitting pin to be positioned at different coordinates on the carriage. This parameter adjustment mechanism enables variation of cutting-edge angle and tilt angle, providing flexibility for different cutting applications while maintaining a relatively simple overall structure.
2Adaptability or versatility
If a single cutting direction is used, then the device structure is simple, but the adaptability for different cutting paths is limited
Solution Approach 1:
The cutting module is designed with universal adaptability to perform cutting operations in multiple directions. The carriage can move along both the media path direction (Y-axis) and media path width (X-axis), enabling the same device structure to handle different cutting paths and orientations without requiring multiple specialized cutting mechanisms.
Solution Approach 2:
The invention adds dimensional flexibility by enabling carriage movement in two orthogonal directions (X-axis and Y-axis). This dimensional expansion allows the cutting system to accommodate various cutting paths including cross-cuts, longitudinal cuts, and angled cuts, transforming a single-direction cutter into a multi-directional cutting system.
3Manufacturing precision
If the cutting blade orientation is fixed, then the device structure is simple, but the precision for bi-directional cutting is insufficient
Solution Approach 1:
The cutting blade orientation is made dynamic through the fitting pin mechanism, which allows the blade to be repositioned relative to the carriage based on the cutting direction. This dynamic adjustment capability ensures precise cutting in both forward and reverse directions by optimizing the blade angle for each cutting operation.
Solution Approach 2:
The fitting pin mechanism introduces asymmetric positioning capability, where the blade can be oriented differently depending on the cutting direction. This asymmetric adjustment allows the system to optimize cutting precision for each direction independently, rather than using a symmetric fixed orientation that would compromise precision in either direction.

AI summary
According to an example, a cutting module may comprise a carriage and a cutting blade, wherein the carriage may be capable of reciprocating movement along a cutting path. The carriage may be supported by a support structure and the cutting blade may have a fitting pin to engage with the carriage. During a first direction movement along the cutting path, the fitting pin may obtain a first cutting-edge angle. During a second direction movement along the cutting path, the fitting pin may obtain a second cutting-edge angle.
