Integrated Coolant Nozzle Housing to Prevent Assembly Leaks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional housing designs for electrical assemblies feature separate coolant connections that are prone to assembly errors, require additional sealing components, and can lead to leakage risks, increasing manufacturing complexity and costs.
Innovation Solution
A housing design with integrated coolant connections formed as a single piece with the housing body, eliminating the need for separate connection units and seals, which reduces assembly errors and leakage risks while simplifying production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate connection units and seals are used for coolant connections, then the housing can be assembled with standardized components, but the assembly complexity increases and leakage risks arise
Solution Approach 1:
The coolant connection is integrated directly into the housing body as a one-piece construction, eliminating the need for separate connection units and seals. This merging of components reduces the total number of parts, simplifies assembly procedures, and eliminates potential leakage points at interfaces between separate components.
2Reliability
If separate connection units are used for coolant connections, then standardized components can be utilized, but the risk of assembly errors and leakage increases
Solution Approach 1:
The coolant connection is integrated directly into the housing body as a one-piece construction, eliminating the need for separate connection units and seals. This merging of components reduces the total number of parts, simplifies assembly procedures, and eliminates potential leakage points at interfaces between separate components.
3Reliability
If separate connection units are used for coolant connections, then modular assembly is possible, but contact corrosion between different materials occurs
Solution Approach 1:
The housing body and coolant connection are made from the same material (aluminum alloy), creating a homogeneous structure. This eliminates galvanic corrosion that would occur between dissimilar materials such as steel connection units, copper seals, and aluminum housing, thereby improving corrosion resistance and reliability.
