Seal Removal Tool with Adjustable Rod and Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing seals, such as gaskets or O-rings, from deep or narrow locations often result in damage due to the lack of specialized tools, making it difficult to access and replace them safely.
Innovation Solution
A seal removal tool featuring a handle, a working rod with a curved plate head and a non-circular body portion, and a positioning mechanism with releasable units, allowing for adjustable lengths and secure locking, enabling effective and damage-free removal of seals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If workers use their hands to remove seals, then the operation is simple and direct, but the worker's hands cannot reach seals installed deep inside components or in narrow environments
Solution Approach 1:
The tool is divided into multiple segments: a handle portion for manual operation, a telescopic rod portion that can be extended to reach deep locations, and a positioning mechanism at the tip. This segmentation allows the tool to bridge the gap between manual operation and access to deep/narrow locations.
Solution Approach 2:
The rod portion is designed to be telescopic and adjustable in length, allowing dynamic adaptation to different depths and narrow spaces. The positioning mechanism can be adjusted and locked at different positions, providing dynamic adaptability to various seal locations while maintaining operational ease.
2Adaptability or versatility
If non-specific tools are used to disassemble seals in deep or narrow locations, then the tool can reach the seal, but the seal is easily damaged
Solution Approach 1:
The tip of the tool features a specialized positioning mechanism with a specific geometric shape designed to match the seal's installation geometry. This local quality at the tip allows precise engagement with the seal without applying excessive force that would cause damage, while still being able to reach deep or narrow locations.
Solution Approach 2:
The positioning mechanism acts as an intermediary between the tool and the seal. Instead of directly applying force with a generic tool, the positioning mechanism engages with the seal's mounting structure, providing a controlled and reliable method for seal removal that preserves seal integrity while maintaining accessibility.
3Device complexity
If a fixed-length rod is used, then the tool structure is simple, but the tool cannot accommodate various sizes and environments
Solution Approach 1:
The rod portion is designed with telescopic segments that can be extended or retracted to adjust the overall length. This dynamic adjustment capability allows the tool to accommodate various sizes and environments without requiring multiple different tool designs, maintaining relative structural simplicity while achieving versatility.
Solution Approach 2:
The tool is designed with a universal positioning mechanism that can engage with different seal types and installation geometries through adjustable positioning units. This multi-functionality allows a single tool design to handle various sizes and environments, reducing the need for multiple specialized tools.
