Corrugated Hose Cutter With Web-Guided Blades for Safe Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools for corrugated hoses often damage the cables or hoses inside when attempting to separate the hose, leading to potential short circuits or leaks.
Innovation Solution
A cutting tool with a base body and at least one knife, designed to score or cut the corrugated hose while minimizing penetration depth to avoid damaging internal cables or hoses. The tool features a jointed design allowing it to open and enclose the hose, with knives positioned to cut between corrugated valleys, ensuring minimal disruption to internal contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cutting tool penetrates deeply into the corrugated hose to sever it, then the cutting effectiveness is improved, but the internal cables or hoses are damaged
Solution Approach 1:
The cutting tool is designed with blades that concentrate cutting action at specific locations (corrugation crests) rather than penetrating uniformly throughout the hose wall. The blades engage only at the outer corrugation crests, creating localized cutting zones that sever the hose without affecting internal components.
Solution Approach 2:
The cutting action is divided into multiple discrete cutting points around the hose circumference rather than a single deep penetration. Multiple blades or cutting edges are distributed around the tool's perimeter, each engaging at different angular positions to collectively sever the hose through shallow, distributed cuts.
2Object-affected harmful factors
If the cutting tool is designed to enclose the corrugated hose for precise cutting, then the protection of internal cables is improved, but the device complexity increases
Solution Approach 1:
The base body employs a jointed, articulated structure that allows dynamic opening and closing motion to enclose the hose during cutting. The joints enable the base body segments to pivot and adapt to the hose diameter, providing a enclosing configuration that positions blades correctly while protecting internal cables, with the added benefit of ease of operation.
3Productivity
If multiple blades are distributed around the opening to reduce rotation angle, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The cutting function is segmented into multiple discrete blades distributed around the opening perimeter. Each blade is responsible for cutting at a specific angular position, allowing the tool to sever the hose through a smaller rotation angle. The blades are spaced to engage successive corrugation crests as the tool rotates, distributing the cutting workload and reducing total rotation required.

AI summary
The invention relates to a cutting tool for corrugated hoses with a base body and at least one knife held therein, wherein the base body has at least two sub-bodies which are pivotably held relative to each other by a joint, and wherein the base body has an opening for receiving a corrugated hose, wherein the circumference of the opening is limited by a lateral surface in one sub-body and a lateral surface in the other sub-body, and wherein at least two axially spaced and radially extending webs are arranged on the lateral surface, and at least one knife projects into the space between the webs on one and/or the other lateral surface, viewed in the axial direction.
