Auxiliary Sliding Elements for Transport Cover Bulk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding cover devices for transport means, such as semi-trailers or trailers, create a significant longitudinal bulk when closed, obstructing access to the load compartment, especially when carrying fully or nearly fully loaded containers or long products.
Innovation Solution
A movement device with auxiliary sliding elements that can transition between an inactive position within the chassis bulk and a work position, allowing the temporary housing of the sliding cover, thereby eliminating bulk and enabling full access to the load compartment during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sliding arch-type elements or curved elements are disposed close together in the second position, then the covering tarpaulin can be compacted and the load compartment can be uncovered, but they determine a considerable longitudinal bulk which prevents access to a corresponding portion of the load compartment
Solution Approach 1:
The patent introduces auxiliary sliding elements that extend the sliding path in the longitudinal direction beyond the rear end of the chassis. This dimensional extension allows the cover to be positioned outside the load compartment volume, eliminating the bulk problem while maintaining coverage functionality.
Solution Approach 2:
The auxiliary sliding elements act as an intermediary structure between the main sliding elements and the ground. They provide a temporary seating that receives the sliding cover, allowing the cover to be positioned away from the load compartment while maintaining its supporting function.
2Ease of operation
If auxiliary sliding elements are added to extend the sliding path beyond the chassis, then access to the load compartment is improved, but the device complexity increases
Solution Approach 1:
The auxiliary sliding elements are integrated with the existing sliding guides and support structures. The auxiliary elements share the same functional purpose as the main elements, and their guides are aligned with the existing guide system, creating a unified sliding mechanism rather than separate independent systems.
Solution Approach 2:
The auxiliary sliding elements serve multiple functions: they extend the sliding path, provide additional support for the cover, create the temporary seating, and enable access to the load compartment. This multi-functionality reduces the need for separate specialized components.
3Volume of moving object
If the auxiliary sliding elements are disposed in the bulk of the chassis in the first inactive position, then the bulk of the means of transport is maintained, but the elements require stable clamping to prevent movement
Solution Approach 1:
The auxiliary sliding elements are designed to be self-stabilizing through their geometric configuration and interaction with the chassis structure. When in the inactive position, their shape and positioning naturally prevent unwanted movement, reducing or eliminating the need for additional active clamping mechanisms.
