Hose Clamp Setting Tool with Angular Positioning Notches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional right angle needle nose pliers and pipe clamp pliers lack control over the positioning and closure of hose clamps, leading to inefficiencies and potential damage when securing hose clamps at specific angles, especially in confined spaces like engine crankcases.
Innovation Solution
A clamp setting tool with pivotally coupled head elements and a stop mechanism, featuring notches for receiving catch and stopper tabs, allows precise control over the hose clamp's pre-clamped and clamped states, preventing accidental closure until properly aligned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional right angle needle nose pliers or pipe clamp pliers are used to set hose clamps, then the hose clamp can be adjusted to some extent, but the tool has little or no control over the closing of the hose clamp and cannot ensure precise positioning at required angles
Solution Approach 1:
The tool head is segmented into multiple elements with specific notches that correspond to specific angular positions. Each notch is positioned at a predetermined angle (e.g., 0°, 45°, 90°, 135°) relative to a reference plane, allowing the hose clamp to be set at precise angular intervals while maintaining ease of operation through simple tab engagement.
2Productivity
If conventional tools are used in confined spaces like engine crankcases, then the hose clamp can be adjusted, but additional time is required and space restrictions may cause damage to surrounding parts
Solution Approach 1:
The tool features a compact head design with localized notches positioned at specific angular locations. This local quality allows the tool to engage hose clamps at precise angles without requiring excessive tool size or creating interference with surrounding engine components, thereby reducing installation time and preventing damage to surrounding parts.
3Reliability
If the hose clamp is set at a predetermined angle relative to surrounding engine components, then safety regulations are met, but conventional tools cannot provide the necessary control and precision
Solution Approach 1:
The notches in the tool head are pre-positioned at specific angular intervals corresponding to predetermined safe angles. This preliminary action ensures that when the hose clamp is engaged with the tool, it is automatically positioned at safe angles without requiring additional adjustment or measurement, thereby meeting safety regulations while maintaining precision.

AI summary
A clamp setting tool secures a hose clamp having a pre-clamped state where a catch tab engages a stopper tab, and a clamped state where the catch tab releases from the stopper tab. The clamp setting tool includes first and second head elements having respective first and second notches formed therein, the second notch positionally corresponds to the first notch. The first and second notches receive the catch and stopper tabs. A stop mechanism is connected to one of the first and second head elements. The clamp setting tool moves the first and second head elements between an open position where the hose clamp is maintained in the pre-clamped state and a closed position where the first and second head elements move the hose clamp to the clamped state. The stop mechanism prevents movement of the first and second head elements from the open position toward the closed position.
