Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic valves experience rapid wear and tear of regulating elements such as split rings due to exposure to high loads, leading to reduced durability and reliability, particularly in applications like hydraulic machines.
Innovation Solution
A hydraulic valve with a split ring assembly incorporating an elastomeric element mounted around the split ring to absorb lateral forces and absorb loads, allowing for adjustable fluid throughput regulation, with the split ring assembly being movable or fixed relative to the hydraulic ram to control fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a split ring is used to regulate hydraulic fluid throughput, then flow control is achieved, but rapid wear and destruction occur due to high loads
Solution Approach 1:
The invention combines a metal split ring with an elastomeric element to create a composite structure. The metal ring provides structural integrity and flow control functionality, while the elastomeric element absorbs lateral forces and mechanical stresses, preventing wear and destruction under high load conditions.
Solution Approach 2:
The elastomeric element acts as an intermediary between the metal split ring and the hydraulic ram outlets. It absorbs and dampens the high mechanical loads and lateral movements, protecting the metal split ring from direct contact with the outlets and preventing rapid wear.
2Strength
If the split ring is made more robust to withstand high loads, then durability improves, but the ability to absorb lateral movements decreases
Solution Approach 1:
The composite structure combines rigid metal for load-bearing with flexible elastomer for movement absorption. The metal split ring maintains structural strength to withstand high hydraulic loads, while the elastomeric element provides flexibility to absorb lateral movements and misalignments.
Solution Approach 2:
Different parts of the split ring assembly have different mechanical properties optimized for their specific functions. The metal ring provides localized strength where load-bearing is needed, while the elastomeric element provides localized flexibility where movement absorption is required.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The elastomeric element absorbs lateral movements, reducing wear and tear, increasing durability and load cycles, and enabling operation under high pressures up to 600 bar, with the split ring assembly capable of withstanding at least 600,000 load cycles.
