Height-Adjustable Substructure Roof for Load Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substructure designs for transporting bulk goods, such as grain and hay, face challenges in securely covering and compressing loads to prevent loss and spoilage during transport, while also adhering to maximum height regulations for road traffic.
Innovation Solution
A structure for a substructure featuring a body with an openable roof that is displaceable along two longitudinal beams, allowing the roof to close over a roof opening and adjust in height using a lifting assembly, which applies a force to compress loads protruding beyond the substructure by lowering the body with the closed roof onto the substructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the load is piled up above the upper opening to make better use of loading space, then the loading space utilization is improved, but the load becomes unstable and may be dispersed by wind or shake during transport
Solution Approach 1:
The patent applies preliminary action by compressing the load before transport begins. The compression device is activated prior to journey commencement to compact the piled load, preventing subsequent dispersion while maintaining the space-efficient piled configuration. This pre-compression stabilizes the load without requiring complete enclosure.
2Object-affected harmful factors
If a cover is used to protect the load from weather, then the load protection is improved, but the loading space utilization decreases due to the need for complete enclosure
Solution Approach 1:
The patent applies partial action by using a cover that protects only the upper portion of the piled load rather than completely enclosing the entire load. The cover is positioned to shield the top surface from weather elements while allowing the load to extend beyond the substructure sides, thereby maintaining loading space utilization while providing necessary weather protection.
3Quantity of substance
If the substructure height is increased to accommodate compressed load, then the loading capacity is improved, but the maximum overall height regulation is violated
Solution Approach 1:
The patent applies preliminary action by compressing the load before transport to reduce its volume and height. This pre-compression allows the load to fit within the substructure without exceeding maximum height regulations, while still achieving adequate loading capacity through efficient space utilization of the compressed material.
4Ease of operation
If the roof is made openable to allow loading from above, then the ease of loading is improved, but the load protection from weather deteriorates
Solution Approach 1:
The patent applies partial action by providing weather protection only for the upper portion of the load through a partial cover or tarpaulin arrangement. The openable roof facilitates loading from above, while the partial cover shields the top surface from weather elements. This selective protection balances loading accessibility with adequate weather defense without requiring complete enclosure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively secures and compresses loads, ensuring they remain covered and dry during transport, while maintaining compliance with maximum height regulations, thus enhancing transportation efficiency and safety.
Implementation Method 1
The lifting drive (10; 11) applies a force in the substructure (2) for compressing a load (L) protruding beyond the substructure (2) by lowering the body (1a) with the closed roof (3) onto the substructure (2) against the pre-tension of the protruding load (L)

AI summary
A structure for a substructure includes a body, and an openable roof. The roof is displaceable at its edges along two longitudinal beams of the body. In a closed state, the roof closes a roof opening between the two longitudinal beams. In an opened state, the roof predominantly exposes the roof opening between the two longitudinal beams. Each longitudinal beam is supported in a height-adjustable manner relative to the substructure via at least one lifting assembly. The body is adjustable at least in height relative to the substructure depending on a height adjustment of the lifting assembly. At least one lifting drive is provided which displaces the body together with the roof in height relative to the substructure. The lifting drive applies a force in the substructure for compressing a load protruding beyond the substructure by lowering the body with the closed roof onto the substructure against the protruding load.
