Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor systems require multiple types of couplings for different sections, leading to increased costs and complexity due to varying environmental conditions and drive tube lengths, which complicates assembly and maintenance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of couplings are used for different sections of the conveyor system, then the system can adapt to different environmental conditions (such as elevated temperatures), but the device complexity and manufacturing cost increase due to requiring multiple coupling types and varying drive tube lengths
Solution Approach 1:
The coupling is designed with a universal interface that can accommodate different environmental conditions through material selection rather than structural variation. The same coupling design can be used in both high-temperature and standard-temperature sections by simply changing the material (e.g., from steel to stainless steel or heat-resistant alloys), eliminating the need for multiple coupling types and reducing device complexity.
Solution Approach 2:
The invention changes the material parameter of the coupling rather than its structural parameters to adapt to different environmental conditions. By selecting appropriate materials with different temperature resistance properties, the same coupling design can function in various thermal environments, thereby maintaining design simplicity while achieving adaptability.
2Adaptability or versatility
If multiple types of couplings with different drive tube lengths are required, then different environmental conditions can be accommodated, but the assembly time and manufacturing cost increase
Solution Approach 1:
The coupling employs a standardized interface design that works with uniform drive tube lengths across all sections. This universal design allows the same coupling to be installed in both high-temperature and standard-temperature sections without requiring different drive tube lengths, significantly reducing assembly time and simplifying manufacturing inventory management.
Solution Approach 2:
The conveyor system is segmented into different environmental zones, but the coupling design remains standardized across all segments. This allows each section to be independently assembled using the same coupling components, facilitating modular assembly and reducing the time required for system installation and maintenance.
3Adaptability or versatility
If conventional couplings are used that require numerous parts, then different environmental conditions can be addressed, but the ease of manufacture decreases due to the number of components
Solution Approach 1:
The coupling design merges multiple functions into a single integrated component rather than using separate parts for different functions. The coupling simultaneously provides mechanical connection, thermal resistance (through material selection), and alignment features, eliminating the need for multiple separate components and washers, thereby greatly simplifying the manufacturing process.
Solution Approach 2:
The coupling is designed as a universal component that performs multiple functions: mechanical connection between drive tubes, support for the conveyor load, and adaptation to different thermal environments through material selection. This multi-functional design eliminates the need for specialized components for each function, reducing the total number of parts and simplifying manufacturing.

AI summary
A conveyor system is provided that comprises at least two types of drive tube couplings that are interchangeable. In one embodiment, the conveyor system comprises a plurality of first drive tube couplings and a plurality of second drive tube couplings. The first drive tube couplings comprise a base portion and an elongated portion that extends from the face of the base portion. The second drive tube couplings comprise a coupling spacer and a coupler comprising an elongated member that abuts the face of the coupling spacer and extends substantially perpendicular thereto. In this embodiment the thickness of the base portion of each of the first drive tube couplings is substantially equal to the thickness of the coupling spacer of each of the second drive tube couplings.
