Diesel Fuel Injector Circlip and Ferrule Removal Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fuel injector recycling and remanufacturing processes require different tools for removing various retaining components like circlips and ferrule rings, leading to a complex and inefficient removal process.
Innovation Solution
A removal tool with a staking unit to deform circlips and a spring fork unit to push and catch ferrule rings, allowing for simultaneous removal of these components from a bore using a single tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If different removal tools are used for different retaining components (circlip, ferrule ring), then each component can be removed effectively, but the removal process becomes complex and inefficient
Solution Approach 1:
The patent combines multiple removal tools into a single integrated tool. The unified removal tool includes a staking unit for removing circlips and a spring fork unit for removing ferrule rings, allowing both functions to be performed by one tool rather than requiring separate tools for each retaining component type.
Solution Approach 2:
The removal tool is designed with multi-functionality to handle different retaining component types. It can remove both circlips (using the staking unit) and ferrule rings (using the spring fork unit), making it a universal tool that replaces multiple specialized tools.
2Productivity
If multiple specialized tools are used for different retaining components, then precise removal is achieved, but the process time increases
Solution Approach 1:
By merging the staking unit and spring fork unit into one tool, operators can remove different retaining components without switching tools, eliminating tool switching time and accelerating the overall removal process.
Solution Approach 2:
The universal removal tool allows operators to handle both circlip and ferrule ring removal in a single tool, avoiding the time loss associated with switching between specialized tools for different component types.
