Solution Overview

Problem

Existing exhaust gas extraction devices are unable to effectively extract gases from vehicles where exhaust ends are integrated into body parts, such as rear bumpers, as they cannot be pushed onto these integrated ends, limiting their usability in modern vehicle designs.

Innovation Solution

The exhaust gas extraction device features a suction opening with an extension that can be positioned relative to the vehicle body, equipped with a stabilization device to maintain contact during engine operation, and flexible sealing to adapt to various shapes and orientations, ensuring continuous gas extraction without interrupting maintenance or repair processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a suction hose with nozzle is pushed onto exhaust ends, then sealing effect is achieved for traditional exhaust pipes, but the device cannot be used for vehicles with exhaust ends integrated into body parts

Engineering Contradiction:
Improvecompatibility with different exhaust configurationsVSAvoidability to push onto exhaust ends
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The suction hose is made flexible and its position is made adjustable rather than fixed. The hose can be dynamically positioned and angled to reach different exhaust configurations, including integrated exhaust ends that are inaccessible to rigid nozzles.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The suction hose is designed as a flexible tube that can bend and conform to different spatial configurations. This flexibility allows it to reach exhaust ends that are integrated into body parts, overcoming the limitation of rigid nozzle designs.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If the vehicle is raised or lowered during maintenance, then access and work space are improved, but exhaust gas extraction is interrupted with conventional devices

Engineering Contradiction:
Improveaccess during maintenanceVSAvoidcontinuous exhaust gas extraction
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The suction hose is designed to be dynamically adjustable in position and angle. When the vehicle is raised or lowered, the hose can be repositioned to maintain contact with the exhaust end, ensuring continuous extraction without interruption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The position parameters of the suction hose (angle, distance, orientation) can be changed to adapt to different vehicle positions. This allows the hose to maintain effective sealing and extraction regardless of whether the vehicle is on the ground or raised.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If the suction opening is fixed in position, then the structure is simple, but it cannot adapt to different vehicle positions and orientations

Engineering Contradiction:
Improvestructure simplicityVSAvoidadaptation to vehicle positions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The suction opening's position is made dynamic rather than fixed. The flexible hose allows the suction opening to be positioned at different locations and angles to adapt to various vehicle positions and orientations while maintaining extraction effectiveness.

Inventive Principle:
Principle #15Dynamics
