Convertible Ramp Body With Cargo Bed Extension for Trailer-Free Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles with cargo beds face inefficiencies due to large vehicles being expensive and inefficient for loading large objects, while smaller vehicles are inadequate for warehouse docking, requiring trailers that decrease mobility and increase expenses.
Innovation Solution
A convertible ramp body that is detachable, extends the cargo bed area, and includes a ramp that pivots to allow for easy loading and unloading without overlaying the cargo bed floor, along with a jack assembly for support and storage integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a large vehicle with cargo bed is used to transport large objects, then the cargo capacity is sufficient, but the vehicle cost and operating expenses increase
Solution Approach 1:
The system divides the cargo transport function into two parts: the base vehicle for mobility and the detachable ramp body with cargo bed extender for cargo capacity. This allows using a smaller, more economical vehicle while achieving large cargo capacity when needed by attaching the ramp body.
Solution Approach 2:
The ramp body is designed to be detachable and convertible, allowing the cargo bed extender to be attached or removed based on cargo requirements. This dynamic configuration enables the vehicle to adapt between small and large cargo capacity modes, optimizing cost efficiency.
2Quantity of substance
If a smaller vehicle with cargo bed is used, then the vehicle cost decreases, but the vehicle cannot be used with warehouse docking bays
Solution Approach 1:
The ramp body with pivotal connection allows the ramp to rotate between a lowered position for docking bay access and an upright position for transport. This dynamic mechanism enables a smaller vehicle to access warehouse docking bays while maintaining cost efficiency.
Solution Approach 2:
The ramp body serves multiple functions: it provides cargo bed extension for docking bay access, acts as a loading ramp, and can be detached for storage or alternative uses. This multi-functionality allows a smaller vehicle to perform tasks previously requiring larger vehicles.
3Volume of moving object
If a trailer is towed to transport large tools, then the cargo capacity increases, but mobility decreases and additional expenses increase
Solution Approach 1:
The ramp body with cargo bed extender is integrated with the vehicle as a single unit, combining the benefits of increased cargo capacity and vehicle mobility. This eliminates the need for separate trailer towing while maintaining full vehicle maneuverability and access to restricted areas.
4Area of stationary object
If a cargo bed extender is added, then the effective area of cargo bed increases, but the complexity of the device increases
Solution Approach 1:
The cargo bed extender is designed as a separate, modular ramp body that attaches to the vehicle. This segmentation allows the extender to be added only when needed, simplifying the base vehicle structure while providing expanded cargo area capability on demand.

AI summary
A convertible ramp body and/or combination of vehicle with a cargo bed and convertible ramp body wherein the convertible ramp body may be positioned about the cargo bed of a vehicle. The convertible ramp body may include a storage shelf body and cargo bed extender on opposite lateral ends of the cargo bed and connected by sidewall beams and a ramp pivotally connected to the cargo bed extender.
