Solution Overview

Problem

Off-road vehicle engines often overheat due to trapped heat in the engine compartment, leading to operational inefficiency and potential damage, as existing systems fail to effectively manage air flow to regulate engine temperature.

Innovation Solution

An air flow control system with movable side panels and actuators that adjust based on engine temperature, allowing air to flow in or out of the engine compartment to maintain a desired temperature range, while also protecting the engine from debris and ambient conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the engine compartment is enclosed to protect the engine from debris and ambient conditions, then engine protection is improved, but heat dissipation deteriorates leading to overheating

Engineering Contradiction:
Improveengine protection from debrisVSAvoidengine temperature
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The side panels are made movable rather than fixed, allowing them to dynamically adjust between open and closed positions based on engine temperature conditions. The controller actuates the panels to open when overheating is detected and close when normal temperature is achieved, resolving the contradiction between protection and heat dissipation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the positional parameter of the side panels from fixed to variable. By controlling the panel position as a variable parameter responsive to temperature feedback, the system optimizes both protection and thermal management performance.

Inventive Principle:
Principle #35Parameter changes

2Temperature

If air flow is increased to cool the engine, then heat dissipation is improved, but engine protection from debris deteriorates

Engineering Contradiction:
Improveengine coolingVSAvoiddebris exposure
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The controller receives feedback from temperature sensors monitoring engine temperature and adjusts side panel position accordingly. This closed-loop feedback control enables the system to increase air flow only when cooling is needed while maintaining protection during normal operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The side panels transition from static to dynamic components that respond to real-time temperature conditions, enabling adaptive control of air flow and debris protection based on actual engine thermal state.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If fixed side panels are used to simplify the system, then device complexity is reduced, but temperature regulation capability deteriorates

Engineering Contradiction:
Improvesystem simplicityVSAvoidtemperature regulation
Core Design Contradiction:
Device complexityVSTemperature

Solution Approach 1:

The system uses the engine's own temperature feedback to automatically control the side panel position without requiring external intervention. The controller and temperature sensors enable the system to self-regulate, balancing complexity with effective temperature control.

Inventive Principle:
Principle #25Self-service

AI summary

An air flow control system for an off-road vehicle includes a first movable side panel configured to be positioned proximate to a first lateral side surface of a body of an engine hood of the off-road vehicle. The system also includes a controller configured to receive a first signal indicative of a temperature of an engine of the off-road vehicle, to access a desired engine temperature range from a storage device, and to output a third signal to one or more actuators indicative of instructions to move the first movable side panel laterally outward relative to the first lateral side surface of the body to enable a flow of air through a gap between the first movable side panel and the body when the first signal indicates that the temperature of the engine of the off-road vehicle is greater than the desired engine temperature range.
