Hose Removal Tool With Pivotable Jaws And Cable Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for removing hoses from vehicles' engine and air filter connections are inefficient due to sticky ends, limited space in the engine room, and the fragility of rubber hoses, which can lead to damage and leakage.
Innovation Solution
A hose removal tool with a handle, first and second jaws, an adjustment unit, and an operation unit, featuring clamp portions and a bolt mechanism that allows for secure gripping and easy removal of hoses, along with a cable and bar system for navigating confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a knife or thin object is used to separate the hose from objects, then the hose can be removed, but the hose may become damaged and the process takes a lot of time due to limited space
Solution Approach 1:
The tool divides the hose removal process into two distinct functional segments: a first jaw with clamp portion for gripping the hose, and a second jaw with pivotable portion for applying leverage. This segmentation allows each part to perform its specific function optimally without compromising the hose
Solution Approach 2:
The tool acts as an intermediary device between the technician and the hose, providing a controlled mechanism for separation. The pivotable portion serves as a mediator that amplifies force while maintaining control, preventing direct damage to the hose that would occur with knife insertion
2Productivity
If conventional manual methods are used to remove hoses, then no special tool is needed, but it takes a lot of time due to limited space in the engine room
Solution Approach 1:
The tool incorporates dynamic elements including a pivotable portion that rotates on a pivot axis, allowing the tool to adapt to confined spaces and maneuver around obstacles in the engine room. The adjustable clamp portions can dynamically adjust their position and angle to access hoses in difficult-to-reach locations
Solution Approach 2:
The pivotable portion extends through the fixed portion at an angle, allowing the tool to operate in three-dimensional space rather than being constrained to a single plane. This dimensional flexibility enables the tool to navigate the limited space in the engine room more effectively
3Ease of operation
If the hose is pulled directly without proper gripping, then removal may be faster, but the hose ends are sticky and cannot be removed easily from the engine and air filter
Solution Approach 1:
The tool replaces the ineffective manual pulling method with a mechanical leverage system. The pivotable portion acts as a lever arm that amplifies the applied force, while the clamp portions provide a secure mechanical grip on the hose, substituting direct pulling with a controlled mechanical separation process

AI summary
A tool for removing hose from objects includes a handle having a first jaw fixed to the handle and a second jaw which is movably connected to the first jaw in a scissors-like way. The first and second jaws have two respective clamp portions so as to clamp the hose. An adjustment unit includes a first member pivotably connected to the first jaw and a second member pivotably connected to the second jaw. A bolt threadedly extends through the first and second members such that when rotating the bolt, the two clamp portions are moved toward each other. An operation unit includes a cable and a bar connected to the cable. The tool is pulled along the object on which the hose is connected by pulling the cable.
