Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional accumulating roller conveyors experience high wear and tear due to load and friction, chain stretching, maintenance difficulties, and temperature resistance issues, leading to inefficiencies and premature wear.
Innovation Solution
The design features a motor-driven accumulating roller chain conveyor with two conveyor chains per track, guided by gear wheels, allowing synchronous operation in both directions, with tensioning devices to manage chain length changes and adjustable drive shafts to maintain tension, reducing wear and enhancing maintenance accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional roller conveyors use conveyor chains or toothed belts driven by motors, then the conveying function is achieved, but high wear and tear occurs due to load and friction on the conveyor guides
Solution Approach 1:
The patent replaces the conventional mechanical drive system (motors driving chains or belts through guides) with a direct shaft connection system. The drive shafts are connected directly to the rollers, eliminating the need for conveyor chains, toothed belts, and guide rails. This substitution of the mechanical transmission system removes the sources of high friction and wear that occurred in the conventional system.
Solution Approach 2:
The patent extracts and removes the harmful intermediate transmission elements (conveyor chains, toothed belts, guide rails) from the system. By taking out these components that caused wear and tear, the system achieves reliable conveying function through direct mechanical connection between the drive shafts and rollers.
2Power
If conveyor chains or toothed belts are used to drive accumulation rollers, then the rollers can be driven, but the chains tend to stretch and change length due to loads
Solution Approach 1:
The patent replaces the flexible chain or belt transmission system with a rigid direct connection system. Drive shafts are directly connected to the accumulation rollers, eliminating chain stretching and length changes. This mechanical substitution ensures stable power transmission without the dimensional instability inherent in flexible transmission elements.
3Productivity
If accumulation rollers are installed along the entire length of the conveyor, then continuous conveying is achieved, but maintenance becomes difficult to perform
Solution Approach 1:
The patent segments the conveyor system into modular units with discrete drive shafts and rollers. Each section can be independently accessed and maintained. The drive shafts are positioned at intervals along the conveyor length, allowing maintenance personnel to access specific sections without disrupting the entire system, thus improving ease of repair while maintaining continuous conveying capability.
4Power
If a side-mounted motor is used to drive the conveyor, then the conveying function is achieved, but the motor is space-consuming
Solution Approach 1:
The patent merges the motor and drive shaft into a compact integrated unit. The motor is directly coupled to the drive shaft, eliminating the need for separate motor mounting space and intermediate transmission components. This integration significantly reduces the space required for the drive system while maintaining full conveying functionality.
Solution Approach 2:
The patent repositions the drive system from a side-mounted configuration to an integrated axial arrangement. By changing the spatial dimensionality of the motor placement and directly coupling it to the drive shaft, the system achieves compact dimensions that reduce the overall space consumption while maintaining drive capability.

Function Achieved in This Case
This solution provides a robust, low-maintenance, and space-efficient conveyor system with reduced wear and tear, capable of handling uneven chain elongation and ensuring continuous operation with minimal friction losses.
Implementation Method 1
The accumulation rollers have a defined rolling resistance, which causes them to remain stationary during transport
Implementation Method 2
conveyor chains of an accumulating roller conveyor track run in guides at least on the upper side, are guided in a circle by gears
