Solution Overview

Problem

In small vehicles, efficiently cooling liquid-cooled engines is challenging due to limited airflow, which complicates the placement of radiators without increasing vehicle size.

Innovation Solution

The radiators are strategically aligned with a storage bin and supported by a frame, with fans forcing air through them, ensuring adequate airflow for cooling while maintaining a compact vehicle design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If radiators are placed to provide sufficient airflow for cooling, then cooling efficiency is improved, but vehicle size increases

Engineering Contradiction:
Improveengine cooling efficiencyVSAvoidvehicle size
Core Design Contradiction:
TemperatureVSVolume of moving object

Solution Approach 1:

The radiator assembly is nested within the front cowling assembly, utilizing the existing structural space of the vehicle body. The storage bin is disposed at least in part inside the front cowling assembly, and the radiators are positioned to be longitudinally and vertically aligned with the storage bin, effectively nesting the cooling system within the vehicle's front structure without increasing overall vehicle dimensions.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The radiators are positioned in a three-dimensional arrangement within the front cowling assembly, utilizing vertical and longitudinal alignment with the storage bin. This spatial arrangement allows the radiators to be integrated into the existing vehicle structure by exploiting available space in multiple dimensions rather than requiring additional lateral space.

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

2Volume of moving object

If radiators are compactly arranged to maintain small vehicle size, then vehicle size is reduced, but airflow for cooling becomes insufficient

Engineering Contradiction:
Improvevehicle sizeVSAvoidengine cooling efficiency
Core Design Contradiction:
Volume of moving objectVSTemperature

Solution Approach 1:

The cooling system is segmented into multiple radiators (typically left and right radiators) that are distributed within the front cowling assembly. This segmentation allows each radiator to access airflow from different directions while maintaining a compact overall arrangement that fits within the vehicle's limited space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The front cowling assembly serves multiple functions: it provides the vehicle's front body structure, contains the storage bin for cargo, and houses the radiator assembly for engine cooling. This multi-functional design allows the cooling system to be integrated into existing structural space rather than requiring dedicated cooling system space.

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

3Quantity of substance

If storage space is increased in small vehicles, then cargo capacity is improved, but space for cooling components is reduced

Engineering Contradiction:
Improvestorage capacityVSAvoidengine cooling capability
Core Design Contradiction:
Quantity of substanceVSTemperature

Solution Approach 1:

The storage bin and radiator assembly are merged within the same front cowling assembly structure. The storage bin is disposed at least in part inside the front cowling assembly, and the radiators are positioned to be longitudinally and vertically aligned with the storage bin, allowing both cargo storage and engine cooling functions to coexist in the same spatial envelope without interfering with each other.

Inventive Principle:
Principle #5Merging (Combining)

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 effectively cools the engine by optimizing airflow over the radiators, maintaining a compact vehicle size while ensuring efficient heat dissipation.

Implementation Method 1

The hot coolant then runs through one or more radiators to be cooled. The cooled coolant is then returned to the engine and the cycle is repeated. In order to operate efficiently, the radiators need air to flow over them in order to absorb heat from the cooling liquid.
