Upright Cutter With Bidirectional Cutting And Adjustable Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutters for packing materials are inefficient due to unidirectional cutting, immovable parts, and inability to adjust cutting angles, leading to reduced efficiency and inconvenience in use.
Innovation Solution
An upright cutter with an adjustable cutting angle and bidirectional cutting capability, featuring a base with a vertical shaft, a pivotally connected pole, and a transverse rod with a movable cutting member equipped with blades, allowing for axial movement and angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cutting member is operated for one-way cutting only, then the structure is simple, but the cutting efficiency is low
Solution Approach 1:
The cutting member is made movable along the transverse rod, transforming from a static fixed-position cutter to a dynamic adjustable cutter. The cutting member can slide back and forth along the transverse rod under manual operation, enabling bidirectional cutting movements and improving cutting efficiency without requiring complex automated mechanisms
Solution Approach 2:
The cutting member is designed to perform multiple functions: it can cut packing materials in both forward and backward directions, and its position can be adjusted along the transverse rod to accommodate different cutting lengths and angles. This multi-functionality resolves the contradiction by enabling efficient bidirectional cutting while maintaining a relatively simple manual operation mechanism
2Adaptability or versatility
If the shaft, frame and cutting member are immovable, then the structure is stable, but the cutting angle cannot be adjusted
Solution Approach 1:
The pole is pivotally connected to the upright post, making it a movable component that can be rotated to adjust the cutting angle. This dynamic element allows the transverse rod and cutting member to be positioned at different angles while maintaining stability during actual cutting operations, resolving the contradiction between adjustability and structural stability
Solution Approach 2:
The cutter is divided into separate functional modules: the upright post provides stable support, the pole provides angle adjustment capability, and the transverse rod with cutting member provides cutting functionality. This segmentation allows each component to fulfill its specific function - the pole can be rotated for angle adjustment while the upright post and base maintain structural stability
3Productivity
If the cutting member is fixed in position, then the structure is simple, but it must be homed after each cut reducing efficiency
Solution Approach 1:
The cutting member is made dynamically movable along the transverse rod, allowing it to be manually repositioned after each cut without requiring automatic homing mechanisms. The operator can directly slide the cutting member to the next cutting position, eliminating time-wasting homing operations and improving cutting efficiency while maintaining simple manual operation

AI summary
An upright cutter for packing materials includes a base, a support device, and a cutting device. The base includes an upright post. The support device has a shaft. The shaft is vertically fixed to the upright post. The cutting device includes a pole. The pole is pivotally connected to the upright post. The pole is connected with a transverse rod. The transverse rod is parallel to the shaft. The transverse rod is provided with a cutting member which is movable axially along the transversely rod. Two sides of the cutting member are provided with blades, respectively. The pole can be pivoted, so that the transverse rod is adjusted to the most appropriate position. By using the blades at the two sides of the cutting member, the cutting member can be moved back and forth on the transverse rod for cutting to improve the cutting efficiency.
