Interlocking Wear-Resistant Panel System for Mining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wear panels in materials handling equipment are expensive to manufacture, require specialized tooling, experience de-lamination and cracking, and are difficult to assemble and modify on-site due to the use of screws, anchors, and hot molding processes, which increase costs and lead times.
Innovation Solution
A wear-resistant panel design featuring a housing matrix with preformed cavities that lock wear-resistant members in place, eliminating the need for screws and anchors, allowing on-site assembly and modification, and incorporating an energy-absorbing layer and backing plate for enhanced durability and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ceramic wear members are encapsulated in polyurethane or rubber, then wear resistance is improved, but de-lamination occurs
Solution Approach 1:
The wear panel is divided into separate components: a housing matrix and individual wear-resistant members. Each member is a discrete element that can be independently replaced, eliminating the bonded interface that causes de-lamination while maintaining wear resistance through the inherent properties of the wear-resistant materials.
Solution Approach 2:
The wear-resistant members are extracted from the encapsulated configuration and placed into separate cavities within the housing matrix. This separation removes the problematic bond between wear-resistant material and encapsulant, allowing each component to maintain its optimal properties without mutual degradation.
2Strength
If screws and anchors are used to attach wear members, then attachment strength is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The attachment function is merged into the housing matrix structure itself through the cavity design. The cavity walls and geometry provide the attachment mechanism, eliminating the need for separate fasteners like screws and anchors. This integration maintains strong attachment while simplifying the overall structure and reducing manufacturing complexity.
Solution Approach 2:
The housing matrix cavities are designed to automatically secure the wear-resistant members through their preformed shapes and cavity wall geometries. The structure serves its own attachment function without requiring external fastening components, reducing both manufacturing steps and assembly complexity.
3Strength
If hot molding rubber process is used, then bonding strength is improved, but thermal shock damages ceramic wear members
Solution Approach 1:
The hot molding process and thermal bonding are extracted from the assembly method. Instead of using heat to bond wear members to a substrate, the design uses mechanical interlocking through cavity geometry. This eliminates thermal shock exposure to ceramic wear members while maintaining secure attachment through the preformed shape and cavity wall interactions.
4Loss of time
If wear panels are assembled off-site and delivered in whole, then assembly time is reduced, but on-site modification becomes difficult
Solution Approach 1:
The wear panel system is segmented into a housing matrix and individual replaceable wear-resistant members. This segmentation allows the housing to be pre-assembled and delivered, while individual members can be easily swapped or modified on-site without affecting the entire structure. The modular design maintains quick assembly benefits while enabling flexible on-site adaptations.
Solution Approach 2:
The system transitions from a static, fixed configuration to a dynamic, easily reconfigurable structure. The wear-resistant members can be removed and replaced without specialized tools or complex procedures, allowing the panel to adapt to different wear patterns or requirements on-site while maintaining the simplicity of initial installation.
