Removable Vehicle Cart Assembly With Secure Roll-In Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage solutions for vehicles require manual loading and unloading of products, lacking a secure and efficient way to move and secure storage units within and outside the vehicle.
Innovation Solution
A removable storage system with a support assembly, movable cart, and locking mechanism that allows easy rolling into and out of the vehicle, featuring horizontal members, retention members, and a locking mechanism with a hook and catch system to secure the cart in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If product storage solutions are installed in vehicles, then cargo storage capability is improved, but manual loading and unloading operations become time-consuming and labor-intensive
Solution Approach 1:
The storage system is designed with a movable cart that can be easily positioned and repositioned within the vehicle, transforming static storage into dynamic, adaptable storage that can be quickly deployed and removed without manual handling of individual items
Solution Approach 2:
The storage system is divided into modular components including the cart, shelves, and locking mechanism, allowing the entire storage unit to be moved as a single integrated module rather than requiring individual item handling, thus reducing loading and unloading time
2Ease of operation
If storage units are made movable for easy loading, then ease of operation is improved, but security and stability of cargo are worsened
Solution Approach 1:
The system transitions from a static to a dynamic state during loading, then to a secure fixed state during transport. The cart can be easily moved when needed but becomes securely locked in position during cargo transport, providing both ease of operation and reliability at appropriate times
Solution Approach 2:
The locking mechanism acts as an intermediary between the movable cart and the vehicle frame, providing a secure connection when engaged and allowing easy movement when disengaged, thus reconciling the contradiction between ease of operation and cargo security
3Reliability
If a locking mechanism is added to secure the cart, then cargo security is improved, but device complexity increases
Solution Approach 1:
The locking mechanism serves as a simple intermediary component that provides secure connection without requiring complex systems. It engages with the horizontal member to lock the cart in place, providing reliable cargo security through a straightforward mechanical design
Solution Approach 2:
The locking function is extracted as a separate, dedicated mechanism rather than being integrated into the cart structure itself. This allows the locking mechanism to be optimized for security while keeping the overall device complexity manageable through functional separation

AI summary
The present invention is a removable storage system for use in a vehicle which allows a storage cart to be rolled into and out of the vehicle and secured within the vehicle. The storage system includes a support assembly adapted to be mounted within a vehicle. The support system has at least one horizontal member extending along the longitudinal side of the vehicle. The movable cart has at least one surface for supporting items, and a locking mechanism for locking the cart to the support system. The horizontal member includes at least one retention member to resist movement of the moveable cart in the longitudinal direction. The locking mechanism engages the horizontal member to lock the cart to the horizontal member to resist movement of the moveable cart in the lateral direction.
