Slidable Conveyance Assembly Lateral Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Previous slidable conveyance assemblies lack lateral support, leading to potential tilting of cargo decks and requiring permanent welding of cross-members, which increases costs and complexity.
Innovation Solution
Incorporating tertiary support bearings that provide lateral stability, allowing for the elimination of permanent welding and enabling a smaller footprint by using primary and tertiary support bearings in conjunction with primary and secondary slide bearings for smooth longitudinal movement and lateral restriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If permanent welding of cross-members is used to provide lateral support, then lateral stability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The lateral support function is segmented from the permanent welded cross-members and assigned to removable cross-members with integrated lateral support bearings. This allows the lateral support function to be provided through modular components that can be independently manufactured and assembled, reducing overall manufacturing complexity while maintaining stability.
Solution Approach 2:
Lateral support bearings are introduced as intermediary elements between the cross-members and the slide channel. These bearings provide the necessary lateral stability without requiring permanent welding, as they can be installed through simple mounting operations on the removable cross-members.
2Stability of the object's composition
If permanent welding of cross-members is used to provide lateral support, then lateral stability is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the lateral support function into separate removable cross-members with integrated bearings, the manufacturing process is simplified. Each component can be manufactured independently using standard fabrication processes without requiring expensive welding operations, thereby reducing overall manufacturing cost while maintaining lateral stability.
Solution Approach 2:
The removable cross-members with lateral support bearings serve as cost-effective alternatives to permanent welded structures. These components can be manufactured more cheaply through standard machining and assembly processes, and while they may have limited service life compared to welded structures, they provide adequate functionality at lower cost.
3Device complexity
If traditional sliding mechanism is used without lateral support, then device complexity is reduced, but cargo deck tilting occurs
Solution Approach 1:
The lateral support bearing is merged with the removable cross-member to create an integrated component. This combination provides both the structural function of the cross-member and the lateral support function of the bearing in a single assembly, maintaining structural simplicity while preventing cargo deck tilting.
Solution Approach 2:
The lateral support bearing acts as an intermediary element that prevents cargo deck tilting without adding complex structural features. It mediates between the simple sliding mechanism and the stability requirement by providing lateral constraint through a compact bearing assembly.
4Ease of manufacture
If removable cross-members with lateral support bearings are used, then manufacturing cost is reduced, but lateral support reliability must be maintained
Solution Approach 1:
The lateral support bearing serves as a reliable intermediary component that ensures consistent lateral support performance. By using precision-manufactured bearings with controlled clearance tolerances, the system achieves reliable lateral support through a simple mounting interface on the removable cross-member, maintaining both cost-effectiveness and reliability.
Solution Approach 2:
The reliability of lateral support is maintained through careful control of bearing parameters, specifically the clearance between the bearing and the slide channel. By optimizing this clearance parameter, the system achieves reliable lateral support without requiring complex structures or expensive manufacturing processes.

AI summary
A device for a slidable assembly may include a support channel, defined by first, second, and third support sides and including a primary support bearing and a tertiary support bearing, and a slide channel, defined by first, second, and third slide sides and including a primary slide bearing and a tertiary slide bearing. In an assembled state, the slide channel may fit around the support channel such that the primary support bearing contacts the first slide side and the primary slide bearing contacts the first support side such that the first slide channel is configured to slide longitudinally with respect to the first support channel, and the tertiary support bearing contacts the first slide channel and the tertiary slide bearing contacts the first support channel to restrict lateral transition of the first slide channel with respect to the first support channel.
