Solution Overview

Problem

Existing filter cooler systems for motor vehicles face challenges in facilitating easy mounting and secure attachment of air filter assemblies to cooler assemblies, which can be damaged by debris and require modifications to the air duct for filter presence or absence.

Innovation Solution

A filter cooler system comprising a cooler assembly, a filter assembly with a permanently affixed flat pleated filter element, and an air duct, all jointly secured to common mounting tabs, allowing for secure and adaptable mounting without altering the vehicle's insurance classification, with the filter element protecting the cooler assembly from damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a filter assembly is added to the cooler assembly, then the filtration capability is improved, but the mounting complexity increases

Engineering Contradiction:
Improvefiltration capabilityVSAvoidmounting complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the filter assembly and cooler assembly into a single integrated filter cooler system that mounts to the vehicle body as one unit. The filter assembly includes a filter element housed in a filter housing with mounting brackets that directly interface with the cooler assembly's mounting structure, eliminating the need for separate mounting operations and reducing overall mounting complexity while maintaining filtration capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting brackets and housing structure serve multiple functions: they provide structural support for both the filter element and cooler assembly, enable secure attachment to the vehicle body, and facilitate easy installation and removal. This multi-functionality reduces the number of separate components needed and simplifies the overall mounting process.

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

2Device complexity

If the cooler assembly is exposed without a filter, then the structure is simpler, but the cooler assembly is vulnerable to damage from debris

Engineering Contradiction:
Improvestructural simplicityVSAvoiddamage from debris
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The filter element is positioned upstream of the cooler assembly in the airflow path, performing preliminary filtration of airborne particles and debris before the air reaches the cooler. This preliminary action protects the cooler assembly from damage while maintaining a relatively simple overall structure through the integrated design.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The filter element acts as an intermediary component between the external environment and the cooler assembly. It intercepts and removes harmful particles from the airflow, preventing them from reaching and damaging the cooler assembly, while the integrated housing maintains structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the filter assembly is permanently fixed to the cooler assembly, then the mounting security is improved, but the adaptability for different vehicle configurations decreases

Engineering Contradiction:
Improvemounting securityVSAvoidadaptability for different vehicle configurations
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The filter assembly and cooler assembly are designed as separable units that can be mounted together or independently. The mounting brackets are designed to attach to the vehicle body structure, allowing the filter assembly to be securely fixed when needed while enabling easy removal or reconfiguration for different vehicle applications or maintenance requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting system incorporates adjustable and removable features that allow the configuration to change based on requirements. The filter assembly can be securely mounted for production vehicles requiring filtration, but can also be easily removed or repositioned for vehicles where filtration is not needed or for maintenance purposes, providing dynamic adaptability.

Inventive Principle:
Principle #15Dynamics
