Integrated Sealing Assembly for Shock Absorber Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing assemblies for shock absorber rods require multiple components, leading to complex and costly assembly processes, increased volume, and weight, as well as logistical challenges, while offering sealing performance that is not optimized.
Innovation Solution
A single, integrated sealing assembly that combines the functions of a sealing ring, reinforcing ring, and guiding ring, made from elastomeric and synthetic materials, where the reinforcing ring serves as both a mechanical support and guiding element, integrated through vulcanization, reducing the number of components and enhancing sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components (sealing assembly, guiding ring, O-ring) are used, then the sealing and guiding functions are achieved, but the assembly complexity and cost increase
Solution Approach 1:
The patent combines the sealing assembly, guiding ring, and O-ring into a single integrated sealing assembly. The sealing ring includes both sealing lips and an integrated guiding portion with a guiding face, eliminating the need for separate guiding and sealing components while maintaining all necessary functions.
Solution Approach 2:
The sealing assembly is designed to perform multiple functions simultaneously: the sealing lips provide sealing action against the rod, the integrated guiding portion provides guiding function, and the O-ring provides energizing force. This multi-functional design reduces the total number of components needed in the system.
2Reliability
If multiple separate components are used, then the sealing and guiding functions are achieved, but the volume and weight of the guiding and sealing unit increase
Solution Approach 1:
The sealing assembly, guiding ring, and O-ring are merged into a single compact component. The guiding portion is integrated directly into the sealing ring structure, and the O-ring is positioned within the same assembly, significantly reducing the overall volume compared to having separate components that would all need to be installed in the bush.
3Reliability
If multiple separate components are used, then the sealing and guiding functions are achieved, but the assembly process becomes more costly and complex
Solution Approach 1:
The integrated sealing assembly requires only a single assembly operation where the entire unit is installed into the bush as one piece. This eliminates the need for multiple separate assembly steps and reduces labor costs, while the single-component design simplifies inventory management and logistics.
4Reliability
If multiple separate components are used, then the sealing and guiding functions are achieved, but the logistics management of components becomes difficult
Solution Approach 1:
By consolidating the sealing assembly, guiding ring, and O-ring into a single integrated component, the patent eliminates the need to manage multiple separate parts in the supply chain. This single-component design simplifies inventory control, reduces the risk of missing parts, and streamlines logistics operations.
