Exhaust Suction Device With Stabilizing Extension
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
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 solution allows for secure and adaptable exhaust gas extraction from vehicles with integrated exhaust ends, enabling maintenance with the engine running, both on the ground and raised, while minimizing damage and ensuring effective sealing, thus enhancing operational safety and reducing installation costs.
