Commercial Vehicle Rack Rails for Movable Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicles face inefficiencies in utilizing rear storage compartment space due to limited rack space and uneven weight distribution, leading to suboptimal loading capacity and handling characteristics.
Innovation Solution
A rack system with guide rails and electrically controllable actuators allows racks to slide laterally, with sensors and control units to balance vehicle inclination, enabling flexible rack positioning and secure fixing to optimize space utilization and weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If racks are fixed in position to maximize storage capacity, then rack space utilization is improved, but weight distribution becomes uneven and handling characteristics deteriorate
Solution Approach 1:
The patent implements laterally movable racks that can be repositioned along guide rails, transforming fixed storage positions into dynamic, adjustable positions. This allows the rack system to adapt weight distribution based on loading requirements while maintaining maximum storage capacity utilization.
2Quantity of substance
If more rack space is provided to store small items, then storage capacity for small items is improved, but floor space for large items is reduced
Solution Approach 1:
The patent transitions from a two-dimensional floor-based storage layout to a three-dimensional vertical rack system with lateral movement capability. This allows small items to be stored in suspended rack positions without occupying floor space, while large items can be placed directly on the floor area.
3Ease of operation
If racks are made movable to balance weight distribution, then handling characteristics are improved, but device complexity increases
Solution Approach 1:
The patent divides the rack system into modular units that can independently move along separate guide rails. Each rack unit operates autonomously with its own actuator, simplifying the control system compared to a fully integrated movable structure while still achieving weight distribution balancing.

AI summary
The invention relates generally to a rack system (5) for a commercial vehicle (1), comprising at least one guide rail (8) fixable to at least one vehicle structure of the commercial vehicle (1) within a rear storage compartment (2) of the commercial vehicle (1). To provide a more efficient way of offering rack space to get a better trade-off between the amount of racks (10) and space for other items, to maximize the utilization rate of the rear storage compartment (2), the rack system (5) comprises at least two racks (10) slidingly supported by the guide rail (8) back and forth in a lateral or longitudinal direction of the commercial vehicle (1) and arranged in series to each other with respect to the guide rail (8).
