Solution Overview

Problem

Conventional side-by-side vehicles (SSVs) have limited passenger and cargo capacity due to the placement of engine and fuel tanks in the cockpit area, which reduces space available for additional passengers or storage.

Innovation Solution

The design incorporates a frame with suspension systems and a motor connected to multiple wheels, featuring a rack and pinion assembly that allows for a more efficient use of space by pivoting passenger seats to create additional storage and cargo space, while maintaining the motor's position for optimal performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the engine and fuel tank are disposed in the cockpit area, then the vehicle structure is simplified, but the passenger carrying capacity and cargo storage capacity are reduced

Engineering Contradiction:
Improvevehicle structureVSAvoidpassenger carrying capacity and cargo storage capacity
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The vehicle is divided into distinct functional zones: the cockpit area for driver and passenger seating, and the rear cargo area for storage. The engine is positioned in the rear cargo area rather than the cockpit, creating clear spatial separation between passenger space and mechanical components. This segmentation allows the cockpit to be dedicated entirely to passenger comfort while the rear section handles mechanical and storage functions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The engine positioning utilizes the longitudinal dimension of the vehicle by placing it in the rear cargo area rather than occupying cockpit space. This dimensional reorganization allows the cockpit area to be fully utilized for passenger seating while the engine occupies the previously underutilized rear space, effectively adding functional capacity without increasing overall vehicle footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If additional passengers or cargo storage space is added to the cockpit area, then the passenger carrying capacity and cargo storage capacity are increased, but the vehicle size and weight are increased

Engineering Contradiction:
Improvepassenger carrying capacity and cargo storage capacityVSAvoidvehicle weight
Core Design Contradiction:
Quantity of substanceVSWeight of moving object

Solution Approach 1:

The cargo area is designed with dynamic, reconfigurable features including foldable rear walls and adjustable shelving that can transform the storage space to accommodate different cargo configurations. This dynamic design allows the same physical space to serve multiple functions - passenger area when needed, and flexible cargo storage when passengers are reduced, maximizing utility without adding permanent structural weight.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rear cargo area serves multiple functions: it provides engine mounting space, cargo storage capacity, and can be configured to accommodate additional passengers when needed. The foldable rear walls and adjustable components allow this single space to adapt between different operational modes, eliminating the need for separate dedicated structures for each function and thereby reducing overall vehicle weight.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Quantity of substance

If the cargo storage space is increased by expanding the vehicle size, then the cargo storage capacity is increased, but the off-road capability and maneuverability are reduced

Engineering Contradiction:
Improvecargo storage capacityVSAvoidoff-road capability and maneuverability
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The cargo area utilizes flexible, foldable rear walls made of thin, lightweight materials that can be collapsed or reconfigured. These flexible structures provide expanded cargo storage capacity when needed but can be folded flat to minimize the vehicle's overall footprint, maintaining compact dimensions for optimal off-road maneuverability and capability without permanent structural additions.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The cargo storage system employs nested, space-efficient designs where shelving and storage components can be collapsed or nested within each other when not in use. This allows the cargo area to expand to full capacity when needed while nesting down to a compact configuration that preserves the vehicle's original maneuverability and off-road performance characteristics.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A vehicle has a front and rear left wheel, and a front and rear right wheel. A left suspension operatively connects one of the left wheels to the left suspension support. A right suspension operatively connects one of the right wheels to the right suspension support. The one of the right front wheel and the right rear wheel is the right front wheel when the one of the left front wheel and the left rear wheel is the left front wheel. A driver seat and at least one passenger seat are disposed side-by-side. A rack and pinion assembly (RPA) is operatively connected to the one of the left front wheel and the left rear wheel and to the one of the right front wheel and the right rear wheel. The RPA is connected to both suspension supports. A steering wheel is operatively connected to the RPA.
