Solution Overview
Problem
Existing compressor arrangements for internal combustion engines face challenges in providing efficient vacuum supply and diagnostics due to complex connections and potential leaks, which affect operational reliability and cost-effectiveness.
Innovation Solution
A compressor arrangement with a vacuum supply device featuring a propellant channel and nozzle in a separate housing, where the propellant outlet connection is designed as a plug-in connection and the inlet connection has through-openings for flat contact surfaces, allowing for direct attachment to the compressor housing and enabling easy assembly and diagnostics through pressure sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the propellant channel is integrated into the compressor housing, then the device complexity is reduced, but the reliability is worsened due to potential leaks at integrated connections
Solution Approach 1:
The propellant channel is separated from the compressor housing into an independent housing component. This segmentation allows the propellant channel housing to be manufactured and tested separately, then assembled to the compressor housing via standardized connections, reducing leak risks while maintaining structural clarity.
Solution Approach 2:
Standardized connection interfaces (through-openings with flat contact surfaces and plug connections) are introduced as intermediary elements between the propellant channel housing and compressor housing. These standardized interfaces provide reliable sealing and easy assembly, resolving the contradiction between simplified structure and connection reliability.
2Reliability
If complex connections are used for the propellant channel, then the reliability is improved, but the ease of manufacture is worsened
Solution Approach 1:
The connection design allows the housing to attach to the compressor housing in a self-aligning manner through the through-openings with flat contact surfaces. The plug connection for the propellant outlet further simplifies assembly by providing a self-explanatory, tool-free connection method, improving ease of manufacture while maintaining reliability.
Solution Approach 2:
Complex mechanical sealing systems are replaced with simple flat contact surfaces and plug connections. This substitution reduces manufacturing complexity while maintaining connection reliability, as the simple geometric forms are easier to manufacture and assemble than complex mechanical seals.
3Ease of repair
If the propellant channel housing is separately manufactured, then the ease of repair is improved, but the device complexity is worsened
Solution Approach 1:
The propellant channel is segmented into a separate housing that can be independently removed and replaced. This segmentation enables targeted maintenance of the propellant channel system without disassembling the entire compressor, improving ease of repair while keeping the overall structure manageable through modular design.
Solution Approach 2:
The separate propellant channel housing with standardized connections serves multiple functions: it contains the propellant channel, provides mounting points for vacuum consumers, and enables easy replacement. This multi-functionality justifies the additional component while providing repair advantages.
