Fork Seal Driver Tool With Rotating Retaining Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fork seal drivers are costly to manufacture due to tight tolerance requirements, prone to misalignment, and can cause damage to seals and fork components during use, as they often rely on separate male and female parts that require precise fitting and are held together by user pressure.
Innovation Solution
A fork seal driver tool composed of two half-cylindrical pieces held together by a rotating retaining ring, eliminating the need for pins and holes, reducing manufacturing costs and ensuring secure alignment without user pressure, thereby minimizing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate male and female parts with pins and holes are used to form the cylindrical driver body, then the driver can be assembled without removing the fork lug, but the manufacturing cost increases due to tight tolerance requirements and precise fitting
Solution Approach 1:
The cylindrical driver body is divided into two separate half-cylindrical pieces that can be assembled around the fork inner leg without removing the fork lug. These segments are joined using a retaining ring mechanism that allows for easier manufacturing tolerances compared to precision-machined male and female parts with pins and holes.
Solution Approach 2:
The two half-cylindrical pieces are combined using a rotating retaining ring that secures them together to form a complete cylindrical driver body. This merging mechanism provides the necessary structural integrity while allowing for more relaxed manufacturing tolerances on individual components.
2Device complexity
If separate male and female parts are held together by user pressure, then the parts can be simple in design, but the driver is prone to misalignment and can cause damage to seals during use
Solution Approach 1:
The retaining ring is designed to be rotatable, allowing the user to easily assemble and disassemble the driver halves. Once assembled, the rotating mechanism maintains secure engagement of the two half-cylindrical pieces, preventing misalignment during the seal installation process while keeping the overall design simple.
3Manufacturing precision
If tight tolerance machining is used to ensure precise fitting of driver parts, then the driver can be reliably aligned, but the manufacturing cost and complexity increase
Solution Approach 1:
By segmenting the driver into two halves that are joined by a retaining ring, the design allows for standard machining tolerances on each half rather than requiring tight tolerances on precision-machined male and female parts. This segmentation simplifies the manufacturing process while maintaining adequate alignment through the retaining ring mechanism.
