Crosswise Offset Roller Carrier for Stable High-Speed Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller-guided conveyor elements in overhead conveyor systems are unstable and unsuitable for conveying heavy objects due to insufficient support, leading to oscillation and wobbling during rapid accelerations, and are not designed for safe operation at high speeds.
Innovation Solution
The conveyor element features crosswise and offset rollers on both sides of the base body, with at least four rollers arranged in an 'X' configuration, providing additional contact points and stability through a form-fitting connection with adjacent elements, allowing for secure guidance and load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional roller-guided conveyor elements are used, then the structure is simple and easy to manufacture, but the guidance is unstable and oscillation occurs during rapid accelerations
Solution Approach 1:
The patent transitions from two contact points at the same height to four contact points distributed in a crosswise offset arrangement, adding spatial dimensionality to the roller configuration. This dimensional change provides stable guidance in both vertical and lateral directions, preventing oscillation during rapid accelerations while maintaining manageable structural complexity
Solution Approach 2:
The conveyor element is divided into multiple roller units arranged in a crosswise offset pattern, with each roller providing independent contact support. This segmentation of the support function into discrete roller elements allows each roller to independently stabilize the guide profile contact, eliminating the oscillation problem while keeping the overall structure modular and manufacturable
2Reliability
If conventional conveying elements with two contact points are used, then the device complexity is low, but the inertial forces of heavy conveyed goods during acceleration cannot be controlled
Solution Approach 1:
The patent increases from two to four contact points by arranging rollers in a crosswise offset configuration across different heights and lateral positions. This dimensional expansion provides sufficient contact points to control the inertial forces of heavy conveyed goods during acceleration, enabling reliable high-speed operation while maintaining a relatively simple four-roller structure
Solution Approach 2:
The crosswise offset roller arrangement is pre-configured to provide optimal contact points with the guide profile before acceleration occurs. This preliminary geometric arrangement ensures that during rapid accelerations, the inertial forces are already countered by the distributed roller support, enabling safe high-speed operation without requiring complex active control mechanisms
3Stability of the object's composition
If conventional conveying elements are used, then the structure is simple, but oscillation and wobble occur during rapid accelerations
Solution Approach 1:
The patent adds spatial dimensionality to the roller arrangement by positioning four rollers in a crosswise offset pattern at different heights and lateral positions, rather than two rollers at the same height. This dimensional expansion creates a stable geometric configuration that prevents oscillation and wobble during rapid accelerations while maintaining a relatively simple four-roller structure
Solution Approach 2:
The patent employs asymmetric positioning of the four rollers in a crosswise offset arrangement, with rollers located at different heights and lateral positions relative to the base body. This asymmetric configuration optimizes contact with the guide profile to prevent oscillation during acceleration, while the modular asymmetric design remains straightforward to manufacture
