Vehicle Cooling Component Carrier for Replaceable Function Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cooling systems with integrated expansion tanks are complex and prone to failure, requiring costly replacements when leaks occur, as the entire component must be exchanged.
Innovation Solution
A component node with a robust, detachable component carrier that allows individual function components like expansion tanks, pumps, and heat exchangers to be easily replaced without affecting the cooling circuit's functionality, featuring adaptable interfaces and fluid connections for space-saving and cost-effective design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If function components are integrated into a single expansion tank component, then the component node is formed, but the component becomes highly complex and susceptible to failure requiring costly replacements
Solution Approach 1:
The patent divides the integrated expansion tank into separate function components (expansion tank, pump, heat exchanger, etc.) that are detachably connected to a component carrier. This segmentation allows individual components to be replaced independently, reducing system complexity and improving reliability by isolating failure points to specific components rather than the entire integrated assembly.
2Adaptability or versatility
If multiple interfaces are formed on the expansion tank to fasten function components, then the component node is formed, but the expansion tank becomes highly complex and susceptible to failure
Solution Approach 1:
The patent extracts the mounting and connection functions from the expansion tank itself and relocates them to a dedicated component carrier. The component carrier provides standardized interfaces for detachably fastening function components, while the expansion tank focuses solely on its fluid storage and expansion functions. This separation reduces the expansion tank's structural complexity while maintaining adaptability through the carrier's interfaces.
3Reliability
If the entire expansion tank must be exchanged when no longer tight, then leak prevention is ensured, but major costs are incurred
Solution Approach 1:
The patent segments the expansion tank system into replaceable function components connected via detachable interfaces on a component carrier. When a leak occurs, only the specific faulty component (e.g., pump, heat exchanger, or expansion tank) needs to be replaced rather than the entire integrated assembly. This significantly reduces maintenance costs while maintaining sealing integrity through proper interface design with sealing elements.
4Ease of repair
If function components are detachably fastened via component interfaces, then individual component exchange is enabled, but the component carrier design becomes more complex
Solution Approach 1:
The component carrier is designed as a universal platform that provides standardized detachable interfaces for multiple different function components. Rather than creating custom mounting structures for each component, the carrier uses standardized connection mechanisms (screws, clips, or bayonet connectors with sealing elements) that can accommodate various components. This multi-functional design enables easy component replacement while keeping the carrier structure relatively simple and modular.
