Raised Frame Support Structure for Commercial Vehicle Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame support structures for commercial vehicles, such as tractor units, face challenges with high bending loads on deflection brackets and space constraints, which affect the distribution and absorption of forces from spring and damper elements.
Innovation Solution
A frame support structure featuring a raised support structure that guides upwards and can be configured to absorb forces from spring and damper elements, with a tank device serving as a reinforcement and support component, and a third longitudinal support structure to manage horizontal forces from steering elements, all integrated with S-folds and hollow profile elements for enhanced stability and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If deflection brackets are used to connect wheel suspensions to the frame, then the forces from spring and damper elements can be transmitted to the frame, but the deflection brackets are subjected to high bending stresses and occupy valuable space
Solution Approach 1:
The patent combines the deflection bracket function with the tank system by integrating the bracket into the tank structure. The tank serves dual purposes: fluid storage and force absorption. The bracket is merged with the tank walls, allowing the tank itself to absorb bending stresses rather than requiring separate robust brackets.
Solution Approach 2:
The tank system is given multiple functions: it serves as both a fluid storage container and a structural component for absorbing suspension forces. The raised support structure also serves dual purposes by providing both structural support and creating space for tank installation.
2Reliability
If robust deflection brackets are used to withstand high bending stresses, then the force transmission reliability is improved, but the space available for other purposes is reduced
Solution Approach 1:
The bracket structure is merged with the tank system, eliminating the need for separate robust brackets that would occupy space. The tank walls themselves serve as the bracket structure, providing both force transmission and fluid storage functions within the same spatial envelope.
Solution Approach 2:
The tank system performs multiple functions simultaneously: fluid storage, structural support, and force absorption. This multi-functionality eliminates the need for additional dedicated bracket structures, thereby preserving valuable space in the vehicle chassis.
3Stability of the object's composition
If the frame support structure is designed with traditional ladder frame configuration, then the structural stability is maintained, but the space utilization is reduced and the complexity of the support structure increases
Solution Approach 1:
The patent merges the support structure with the tank system by integrating the tank into the raised support structure. The tank becomes part of the load-bearing structure, eliminating the need for separate traditional ladder frame components and optimizing space utilization.
Solution Approach 2:
The support structure is raised vertically to create a raised support structure, which provides structural stability while creating additional horizontal space for tank installation. This vertical dimensionality change allows the tank to be positioned in the space between the raised support structures.
4Area of stationary object
If the tank system is integrated into the raised support structure, then the space utilization is optimized and the structural integrity is enhanced, but the complexity of the frame support structure increases
Solution Approach 1:
The tank system is merged with the support structure, creating an integrated assembly where the tank serves as both storage and structural component. This integration reduces the number of separate parts and simplifies the overall structure despite the enhanced functionality.
Solution Approach 2:
The tank system performs multiple functions including fluid storage, structural support, and force absorption. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall system complexity while optimizing space utilization.
