Collapsible Cargo Carrier with Spooling Bed Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cargo carriers are large, cumbersome, and obstructive, making them difficult to store, transport, and install, and they can complicate parking and reversing due to their size and protrusion from the vehicle.
Innovation Solution
A collapsible cargo carrier with a flexible bed and spooling mechanism that allows the bed to be supported by a frame in an extended position for cargo and collapsed around a rotatable bar for compact storage, featuring a connection mechanism to vehicles that is easy to install and remove.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional cargo carriers are used, then cargo can be transported, but the carriers are large and cumbersome to store, transport, and install
Solution Approach 1:
The cargo carrier employs a dynamic collapse mechanism that transforms the rigid structure into a compact configuration. The frame includes collapsible legs with pivot joints that allow the carrier to transition between an extended cargo-carrying state and a collapsed storage state, reducing its volume and improving ease of operation.
Solution Approach 2:
The cargo carrier design allows components to be nested within each other when collapsed. The side walls and bed can be positioned inside or against the frame structure, creating a compact nested configuration that significantly reduces storage volume while maintaining full functionality when deployed.
2Quantity of substance
If conventional cargo carriers are used, then cargo can be transported, but they protrude out from the vehicle and block access to the trunk
Solution Approach 1:
The cargo carrier is designed with dynamic adjustability, allowing it to be collapsed when not in use. This enables the carrier to be stored within or close to the vehicle without protruding, thereby maintaining full access to the trunk and rear of the vehicle while preserving cargo capacity when deployed.
Solution Approach 2:
The cargo carrier frame is divided into segmented, collapsible sections with pivot joints. This segmentation allows the structure to be folded and compacted, enabling it to be stored without blocking vehicle access while maintaining sufficient cargo capacity when extended.
3Quantity of substance
If conventional tow-behind cargo carriers are used, then cargo can be transported, but parking and driving in reverse become difficult
Solution Approach 1:
The cargo carrier features a dynamic collapse mechanism that allows it to be quickly folded into a compact configuration. This enables the carrier to be stowed when not needed, eliminating interference with parking and reverse driving maneuvers while maintaining full cargo capacity when deployed.
Solution Approach 2:
The frame structure is segmented with pivot joints that enable easy folding and collapsing. This segmentation allows the carrier to be rapidly transitioned between extended and collapsed states, improving vehicle maneuverability when the carrier is not in use while preserving cargo transport capability.

AI summary
A collapsible cargo container comprises a frame that is attachable to a vehicle, a bed comprising a flexible material, and a spooling mechanism connected to the frame, the spooling mechanism comprising a rotatable bar connected to an end of the bed. When the collapsible cargo container is in an extended position, the bed is supported by the frame so that it can support cargo and when the collapsible cargo container is in a collapsed position, at least a portion of the bed is spooled around the rotatable bar.
