Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional idler rollers in conveyor systems are costly to inventory due to unpredictable demand, require extensive storage space, and are difficult to customize, leading to inefficiencies in production and maintenance.
Innovation Solution
A modular idler roller system using solid or molded plastic discs with recessed ends and adaptable shafts, allowing assembly with minimal machinery, reducing the need for heavy inventory and enabling quick customization to meet various conveyor specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional steel tube idler rollers with ball bearings are used, then the rollers provide reliable support and smooth operation, but they require extensive inventory storage space and high inventory costs due to unpredictable demand
Solution Approach 1:
The roller is divided into separate modular components: a standard shaft, end adapters with bearing assemblies, and plastic disc elements. These segments can be stored separately in compact configurations and assembled on-demand to create various roller specifications, reducing the storage space required for complete assembled rollers.
Solution Approach 2:
The shaft and end adapter components are designed as universal parts that can be used across multiple roller configurations and applications. A single shaft can accommodate different end adapters to create various roller types, eliminating the need to maintain separate inventories for each roller specification.
2Strength
If conventional steel tube idler rollers are used, then the rollers provide durable support, but they are difficult to customize for different conveyor specifications
Solution Approach 1:
The roller system is segmented into interchangeable components including shafts, end adapters, and plastic discs. This segmentation enables easy customization by selecting and assembling different combinations of standard parts to meet specific conveyor requirements without custom manufacturing.
Solution Approach 2:
The roller configuration is made dynamic and adjustable through the modular assembly system. Users can reconfigure rollers by swapping end adapters and plastic disc elements to adapt to changing conveyor specifications, maintaining durability while enabling versatility.
3Manufacturing precision
If custom-produced metric size idler rollers are manufactured, then the rollers meet specific dimensional requirements, but they are very expensive to produce
Solution Approach 1:
Standard shafts and end adapters are designed with universal dimensions and interfaces that can accommodate various roller lengths and configurations. This universality allows metric and other non-standard sizes to be produced by assembling existing standard parts rather than custom manufacturing entire rollers, significantly reducing production costs.
Solution Approach 2:
The system enables parameter changes in roller specifications by combining standard components in different configurations. Dimensional requirements are met by selecting appropriate combinations of shaft lengths, end adapter types, and plastic disc quantities rather than custom manufacturing each dimension set.
4Strength
If traditional steel tube idler rollers are used, then the rollers provide structural integrity, but they have shorter usable life and potential for worn parts with sharp edges to damage conveyor belts
Solution Approach 1:
The roller combines traditional steel components (shaft, end adapters) with engineered plastic materials (UHMW or acetal plastic discs). This composite construction maintains the structural integrity and strength of metal support elements while the plastic disc elements provide belt-contact surfaces that are wear-resistant and do not develop sharp edges, extending the roller's usable life and protecting conveyor belts.

AI summary
A modular roller system. The system includes a mechanical shaft and at least one plastic disc. The one or more the discs may include a recessed end abutting one side of the plastic disc. The system also includes an assembly in physical contact with the recessed end and positioned in an inside of the recessed end. The one or more discs slide onto and around the mechanical shaft using frictionless bearing system.
