Vehicle Exhaust Line Assembly with Nested Sensor Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of exhaust systems in vehicles, particularly agricultural machines, leads to increased installation space requirements and vulnerability to mechanical and thermal damage, complicating assembly and maintenance, while existing solutions that relocate components outside the engine compartment can impair the operator's view and expose sensors to heat.
Innovation Solution
An exhaust line arrangement with components positioned outside the engine compartment, supported by a housing with cooling openings and a support element, incorporating sensor devices within the support element or housing for protection and easy access, and using fastening elements to shield sensors from heat, allowing for efficient assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If exhaust line components are arranged outside the engine compartment, then installation space is improved, but sensors are exposed to heat and mechanical damage
Solution Approach 1:
The sensor device is nested within the support element, which provides both mechanical protection and thermal insulation. The housing encloses the first exhaust line component, creating a protective structure that shields sensors from external harmful factors while maintaining compact arrangement outside the engine compartment.
Solution Approach 2:
The support element acts as an intermediary structure between the exhaust line component and the sensor device. It provides thermal insulation and mechanical protection, mediating the exposure to heat and mechanical damage while enabling the sensor to function in the externally arranged exhaust system.
2Volume of moving object
If multiple exhaust line components are fastened together for space-saving arrangement, then installation space is improved, but mechanical damage to components or sensors can occur
Solution Approach 1:
The housing encloses the first exhaust line component, creating a protective structure that prevents mechanical damage during assembly and operation. This nested arrangement allows compact positioning outside the engine compartment while maintaining component integrity through protective enclosures.
3Ease of operation
If sensors are arranged outside the engine compartment, then assembly and maintenance are simplified, but sensors are exposed to thermal and mechanical influences
Solution Approach 1:
The sensor device is arranged within the support element, which provides protective enclosure while maintaining external accessibility. This nested configuration enables simplified assembly and maintenance operations outside the engine compartment while simultaneously protecting sensors from thermal and mechanical harmful factors through the protective structure.
