Elastomeric Rider Bar With Embedded Wear-Resistant Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rider bars on screen cloths and wear-resistant linings experience significant wear and have shorter service lives due to direct contact with large material fractions, leading to reduced efficiency and premature wear on the apertured portions of the cloth.
Innovation Solution
Integration of wear-resistant elements, such as ceramic or steel units, along the length of the rider bars, which are partially embedded in elastomeric material to distribute and absorb the load, extending the service life and maintaining elasticity while minimizing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rider bars are made entirely of elastomeric material, then the cloth maintains flexibility and elasticity, but the rider bars experience significant wear and have shortened service life
Solution Approach 1:
The rider bar is constructed as a composite structure combining elastomeric material for flexibility and wear-resistant material (such as ceramic or metal) for enhanced durability. The wear-resistant material is integrated into the elastomeric rider bar, creating a composite component that simultaneously provides both flexibility and wear resistance, resolving the contradiction between maintaining elasticity and improving wear resistance.
2Duration of action of stationary object
If wear-resistant material is added to rider bars, then service life is extended, but manufacturing complexity and cost increase
Solution Approach 1:
Instead of making the entire rider bar from wear-resistant material, the invention applies wear-resistant material only to specific areas where wear occurs most intensely. This localized approach extends service life where needed while keeping the overall structure simple and cost-effective to manufacture, resolving the contradiction between extending service life and maintaining manufacturing simplicity.
3Reliability
If rider bars are made more durable, then wear on apertured portions is reduced, but the rider bars become less flexible
Solution Approach 1:
The composite structure allows the elastomeric base material to maintain flexibility and elasticity while the integrated wear-resistant material provides durability. The two materials work together synergistically, with the elastomeric portion providing flexibility and the wear-resistant portion providing durability, thus resolving the contradiction between durability and elasticity.
Applied Scientific Principles
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 solution significantly extends the service life of rider bars by distributing the load and providing a dampening effect, reducing wear and maintaining the rider bars' functionality and cost-effectiveness.
Implementation Method 1
The rider bar is made of elastomeric material... providing a dampening effect... absorbing the load
Implementation Method 2
a wear-resistant element being arranged in the rider bar, so that large fractions of material substantially move over, and thus exert wear on, these wear-resistant elements
