Vehicle Cargo Guide Rail Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cargo storage areas in vehicles lack effective means to secure items, allowing them to move around during transport due to the open nature of the cargo space.
Innovation Solution
A cargo management system featuring guide rails with elongate slots and tracks with locking portions on the load floor, a support member with adjustable extensions, and a locking mechanism that moves between unlocked and locked positions to secure the support member adjacent to the load floor, utilizing a locking member projection to engage the track's locking portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cargo storage area is left open for easy access, then ease of operation is improved, but cargo security deteriorates allowing items to move around during transport
Solution Approach 1:
The support member is designed to be movable between a retracted position (parallel to load floor) and an extended position (perpendicular to load floor), allowing the system to dynamically adapt between providing access and providing cargo security. The locking mechanism enables the support member to be positioned at different locations along the guide rail, creating variable cargo compartments that secure items while maintaining operational flexibility.
2Reliability
If a support member is added to secure cargo, then cargo security is improved, but device complexity increases
Solution Approach 1:
The support member serves multiple functions: it acts as a cargo divider when extended, provides structural support when retracted, and can be positioned at various locations along the guide rail to create different cargo compartment configurations. The locking mechanism with multiple locking portions allows the same component to secure the support member at different positions, eliminating the need for separate fixing mechanisms for each position.
Solution Approach 2:
The extensions are received within the elongate slot of the guide rail, creating a nested arrangement where the support member housing contains the extensions, and the guide rail contains the extensions during movement. This nested structure reduces overall system complexity by integrating multiple components into a compact arrangement.
3Adaptability or versatility
If the support member can be positioned at multiple locations, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The guide rail is segmented into multiple discrete locking portions spaced at different locations along its length. The locking mechanism includes corresponding locking portions that can engage with any of these segmented positions. This segmentation allows the support member to be securely positioned at multiple locations without requiring continuous adjustment mechanisms, simplifying both manufacturing and assembly while maintaining high adaptability.

AI summary
A cargo management system for use in a vehicle cargo area includes at least one guide rail disposed on the load floor of the cargo area and include an elongate slot at least partially formed therein. At least one track incorporating a plurality of locking portions is disposed on the load floor proximate the at least one guide rail. A support member includes a housing and one or more extensions at least partially received within the elongate slot of the at least one guide rail. The support member is disposed adjacent to and movably positioned relative to the load floor. A locking mechanism is adjustably connected to the support member housing and includes a locking member having a projection that releasably engages one or more locking portions of the at least one track.
