Curvilinear Conveyor Support with Replaceable Wear Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing curvilinear supports for chain conveyors suffer from wear-induced unserviceability, requiring periodic replacement of rails, which necessitates lengthy standstills of the conveying line due to the need to remove and replace the entire support.
Innovation Solution
The curvilinear support design integrates covering profiles with coupling members that protect the rails from direct chain contact, allowing for easy replacement of worn profiles without removing the support from the conveyor line, utilizing materials with improved tribological characteristics for the profiles and structural integrity for the base and rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rails are made of material with improved tribologic characteristics, then wear resistance is improved, but device complexity increases due to requiring different materials for base and rails
Solution Approach 1:
The support structure is divided into distinct components: a base element and separate covering profiles that can be independently replaced. The covering profiles are detachably coupled to the base, allowing them to be segmented from the main structure for individual maintenance without affecting the entire support system.
Solution Approach 2:
The covering profiles are designed as replaceable, consumable components with shorter service life than the base structure. When worn, only the profiles need replacement rather than the entire support, enabling economical maintenance by replacing only the worn tribologic components while retaining the durable base structure.
2Stability of the object's composition
If rails are fixed non-removably to base, then structural stability is improved, but ease of repair deteriorates as entire support must be removed for rail replacement
Solution Approach 1:
The support system is segmented into a permanent base structure and removable covering profiles. The profiles are detachably coupled to the base through coupling members that allow secure attachment during operation but enable easy removal for maintenance, separating the structural function from the wear-prone contact surfaces.
Solution Approach 2:
The coupling between base and covering profiles transitions from a static permanent connection to a dynamic reversible connection. The profiles can be firmly attached during conveyor operation to maintain structural stability, then easily detached when maintenance is needed, adapting the connection state based on operational requirements.
3Reliability
If entire curvilinear support is removed for rail replacement, then complete maintenance is achieved, but loss of time increases due to lengthy standstills
Solution Approach 1:
The maintenance scope is segmented from complete support replacement to selective profile replacement. Only the worn covering profiles need to be removed and replaced, while the base structure and functional components remain in place, dramatically reducing maintenance time and conveyor downtime.
Solution Approach 2:
The wear-prone covering profiles are extracted as separate replaceable components from the main support structure. This extraction allows maintenance to focus only on the specific worn elements rather than the entire assembly, enabling quick replacement without disturbing the base or other functional components of the support system.
4Reliability
If covering profiles are made with improved tribologic characteristics, then friction resistance is improved, but manufacturing precision requirements increase for coupling interfaces
Solution Approach 1:
The system separates the tribologic function (handled by covering profiles with specialized materials) from the structural function (handled by the base). The coupling interfaces between profiles and base are designed with standardized coupling members that use simple geometric features like protrusions and recesses, maintaining manufacturing precision requirements at acceptable levels while enabling material optimization for wear resistance.

Function Achieved in This Case
This design enables quick and convenient maintenance by replacing only the worn profiles, minimizing downtime and extending the service life of the support without disrupting the conveyor line operation.
Implementation Method 1
The curvilinear support also comprises covering profiles positioned on the rails and coupling members between the covering profiles and the rails to couple them to one another
