Solution Overview

Problem

Single-axle vehicles face inefficiencies in drive operation and environmental impact due to inadequate cooling, leading to increased fuel consumption and reduced functionality from dust contamination of radiators.

Innovation Solution

The design incorporates a cooler connected to the drive via a cooling circuit, with spiked rollers that allow air intake from the sides, keeping dust out and utilizing the spiked rollers' metal material to cool air, thereby improving cooling efficiency and reducing dust accumulation on the cooler.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the cooler draws in air from the front of the vehicle, then cooling is provided to the drive unit, but dust contaminates the cooler reducing its cooling capacity

Engineering Contradiction:
Improvecooling capacityVSAvoiddust contamination
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the harmful dust intake function from the cooler by redirecting its air intake away from the front of the vehicle (where dust is generated by work implements) to the sides of the vehicle. This separates the cooling function from the dust-laden environment, maintaining cooling capacity while eliminating dust contamination.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The spiked rollers act as intermediaries in the air flow path. They draw in air from the sides of the vehicle and direct it toward the cooler, serving as a mediator that provides dust-free air intake while maintaining the cooling function. The rollers' air-permeable design allows them to facilitate this intermediate air flow without blocking it.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the spiked rollers are made air-permeable to allow air intake from sides, then dust-free air reaches the cooler, but the structure becomes more complex

Engineering Contradiction:
Improvedust contaminationVSAvoidroller structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The spiked rollers are designed with air-permeable properties, allowing air to pass through them. This porosity enables the rollers to draw in dust-free air from the sides of the vehicle and direct it to the cooler, achieving the dust protection goal while using a relatively simple structural approach.

Inventive Principle:
Principle #31Porous materials

3Object-affected harmful factors

If the cooler is positioned to receive air from spiked rollers, then dust accumulation is reduced, but the cooling air may be warmer

Engineering Contradiction:
Improvedust accumulationVSAvoidcooling air temperature
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The patent applies local quality by having the spiked rollers cool the air locally as it passes through them before reaching the cooler. The metal rollers absorb heat from the air, pre-cooling it before it enters the cooler, thereby reducing the temperature differential needed and improving overall cooling efficiency.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This configuration enhances cooling performance, reduces fuel consumption, and maintains cleaner cooler operation by directing dust-free air into the vehicle, improving the overall efficiency and environmental friendliness of the single-axle vehicle's drive system.

Implementation Method 1

The drive unit heats up and therefore requires cooling. This is achieved using a cooler. The cooler is functionally connected to the drive unit. Functional connection means that a cooling circuit is arranged between the drive unit and the cooler. This cooling circuit contains a cooling medium.

Methodology Applied
Scientific EffectHeat transfer: Conduction (thermal)

Implementation Method 2

utilizing the spiked rollers' metal material to cool air

Methodology Applied
Scientific EffectThermal conduction: Conduction (thermal)
