Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side-by-side off-road vehicles face challenges in design and assembly due to variations in models, requiring different frame components and compromising storage capacity and protection from the elements, with existing cargo beds being inconvenient for mixed cargo and lacking additional storage options.
Innovation Solution
The use of modular frame designs allowing for different vehicle configurations with common dimensional characteristics, incorporating a configurable storage compartment and a pivotable cargo bed that can extend over the motor compartment, providing additional storage and protection from the elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different frame components are used to accommodate various vehicle models with different features, then vehicle model versatility is improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The patent applies universality by designing a standardized frame module system where a common set of frame modules can be configured to create multiple different vehicle models. The frame modules include standardized components such as a first frame module with a first longitudinal member, a second frame module with a second longitudinal member, and connecting components that can assemble different vehicle configurations using the same basic building blocks, thereby reducing the variety of unique frame components needed while maintaining model versatility.
Solution Approach 2:
The patent applies segmentation by dividing the vehicle frame into separate, modular frame modules that can be independently manufactured and then assembled. The frame is segmented into a first frame module, a second frame module, and connecting components, allowing each module to be produced separately and then joined together to form complete vehicle frames for different models, reducing manufacturing complexity and component variety.
2Ease of operation
If cargo bed is made pivotable for easy dumping, then ease of operation is improved, but reliability and cargo security deteriorate when mixed cargo is transported
Solution Approach 1:
The patent applies dynamics by making the cargo bed pivotable relative to the frame modules, allowing it to rotate between a horizontal transport position and a tilted dumping position. This dynamic capability enables easy cargo dumping while maintaining cargo security during transport through proper positioning and locking mechanisms that stabilize the cargo bed in the horizontal position.
3Volume of moving object
If cargo bed is used for all cargo storage, then storage capacity is improved, but ease of operation deteriorates due to lack of selective access and protection from elements
Solution Approach 1:
The patent applies segmentation by dividing the cargo storage function into separate compartments: an open cargo bed for bulk cargo and a covered storage compartment for items requiring protection or selective access. This segmentation allows the vehicle to maintain total storage capacity while improving ease of operation by enabling users to access different cargo types independently without moving other items.
Solution Approach 2:
The patent applies dimensionality change by utilizing the vertical space above the cargo bed to position the storage compartment. The storage compartment is arranged in an upper dimension relative to the cargo bed, allowing both storage spaces to coexist without compromising total cargo capacity while providing protected access to frequently used items.
4Volume of moving object
If vehicle space is optimized for cargo bed, then storage capacity is improved, but device complexity increases to provide additional storage compartments
Solution Approach 1:
The patent applies universality by designing the storage compartment and its support structure to serve multiple functions: providing protected cargo storage, supporting the cargo bed pivot mechanism, and utilizing existing frame module vertical members. This multi-functionality reduces the need for additional dedicated support structures, thereby minimizing device complexity while maintaining storage capacity.

AI summary
A vehicle has a frame including a front frame module defining at least in part a cockpit, and a rear frame module having a cargo bed support structure. The vehicle has a rear seat row or a cargo bed support structure extension disposed rearwardly of a front seat row. A wheelbase length measured between centers of front and rear wheels of the vehicle is approximately the same regardless of which of the rear seat row and the cargo bed support structure extension is disposed rearwardly of the front seat row. A longitudinal cargo pivot distance measured between the center of the front wheels and a cargo bed pivot axis is approximately the same regardless of which of the rear seat row and the cargo bed support structure extension is disposed rearwardly of the front seat row. A method of assembling a vehicle of a family of vehicles is also contemplated.
