Solution Overview

Problem

Side-by-side utility vehicles have complex and difficult maintenance due to the existing layout of components, requiring removal of the vehicle cover for routine maintenance of components like the air filter and electrical control unit, which can lead to secondary pollution and dust entry.

Innovation Solution

The design includes a frame with a front, middle, and rear frame portion, and a vehicle cover with baffles and plates that define a cabin, allowing for an elevated intake manifold and access ports for the air filter and electrical control unit, enabling maintenance without removing the vehicle cover, thus reducing dust entry and simplifying the overhaul process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If components like air filter and electrical control unit are mounted inside the vehicle cover, then the vehicle structure is compact and protected, but maintenance becomes complex and difficult requiring removal of the vehicle cover

Engineering Contradiction:
Improvevehicle structure compactnessVSAvoidmaintenance accessibility
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The vehicle cover is segmented into multiple parts: a first vehicle cover portion, a second vehicle cover portion, and a third vehicle cover portion. The air filter is accessible through a first access port in the first portion, while the electrical control unit is accessible through a second access port in the second portion. This segmentation allows maintenance of specific components without removing the entire vehicle cover, resolving the contradiction between compact structure and maintenance accessibility.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the vehicle cover is removed for maintenance, then components become accessible, but secondary pollution and dust entry occur

Engineering Contradiction:
Improvecomponent accessibilityVSAvoiddust entry and pollution
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

Access ports are pre-designed and pre-positioned in the vehicle cover structure during manufacturing. These ports are equipped with protective covers or seals that can be opened only when maintenance is needed. This preliminary preparation allows maintenance personnel to access components through designated ports without removing the entire vehicle cover, thereby preventing dust entry and secondary pollution while maintaining component accessibility.

Inventive Principle:
Principle #10Preliminary action

3Ease of repair

If routine maintenance requires removal of the vehicle cover, then all components are accessible, but maintenance time and complexity increase

Engineering Contradiction:
Improvecomponent accessibilityVSAvoidmaintenance time
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The vehicle cover is divided into multiple accessible portions with dedicated access ports for different components. The air filter can be maintained through the first access port, and the electrical control unit through the second access port, independently of each other. This segmentation enables maintenance personnel to perform routine maintenance on specific components quickly without the time-consuming process of removing and reinstalling the entire vehicle cover, significantly reducing maintenance time while maintaining accessibility.

AI summary

The invention relates to a side-by-side utility vehicle. The side-by-side utility vehicle includes a frame, a vehicle cover, a prime mover assembly, an intake and exhaust system, and electrical control unit. The intake and exhaust system comprise an intake manifold and an intake seat. The intake seat defines an mounting hole and an intake cavity having an opening. At least one side of the side-by-side utility vehicle defines a intake seat mounting cavity. One end of the elevated intake manifold extends into the intake cavity and is in fluid communication with the intake manifold, and the other end of the elevated intake manifold extends away from the intake seat and is substantially along the vertical direction. The rear baffle defines a filter element access port in fluid communication with the cabin and the air filter.
