Vehicle Cargo Rack with Dual Hitch Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo rack assemblies lack versatility and efficiency in transporting firewood, particularly in stacking and transporting wood between different types of vehicles, such as tractors and pickup trucks, without secure and stable solutions for varying wood sizes and distances.
Innovation Solution
A vehicle attachable cargo rack assembly featuring a rectangular base with perpendicularly extending end rails, a front rail with a three-point hitch attachment for tractors, and a shank for hitch receivers on other vehicles, allowing secure stacking and transportation of firewood, with adjustable crossmembers and fasteners for securing wood pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cargo rack assembly is designed to work with a specific vehicle hitch type, then it provides secure attachment for that vehicle, but it cannot be used with other vehicle types
Solution Approach 1:
The cargo rack assembly incorporates two different hitch attachment mechanisms (three-point hitch attachment and receiver hitch attachment) on the same frame, enabling it to be universally compatible with multiple vehicle types including tractors, trucks, and utility vehicles, thus resolving the contradiction between specialized attachment security and broad vehicle compatibility
2Ease of manufacture
If the frame structure is simplified for easy manufacturing, then production cost decreases, but stacking capability and wood support stability are compromised
Solution Approach 1:
The frame is segmented into modular components including vertical posts, horizontal rails, and adjustable crossmembers that can be independently manufactured and assembled, simplifying production while maintaining the structural integrity needed for stable wood stacking through the coordinated arrangement of these segments

AI summary
A vehicle attachable cargo rack assembly for transporting firewood includes a frame comprising a base that is rectangularly shaped. A pair of end rails is coupled singly to and extends from opposing end members of the base. A front rail is coupled to a front member of the base and extends between the pair of end rails so that the frame is configured to stack pieces of wood. A hitch attachment that is coupled to the front rail is three point type and thus configured to couple to a three point hitch that is coupled to a first type of vehicle, positioning a user to lift and transport the frame. A shank that is coupled to the base and extends from the front member is configured to couple to a hitch receiver that is coupled to a second type vehicle, positioning the user to transport the frame.
