Sealing Retainer for Electronic Module Cooling Gas Passageway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
State-of-the-art electronic assemblies using the VITA 48.8 AFT standard face technical drawbacks due to complexity in providing precision tapers on plug-in electronic modules and the requirement for gaskets that can cause binding, leading to gas leaks and reduced heat transfer.
Innovation Solution
The electronic assembly incorporates a sealing retainer with a rigid body, a compressible body, and a sealing gasket, which aligns with the chassis and module cooling gas passageways, ensuring a secure and leak-proof connection between the chassis and electronic module without the need for precision tapers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If precision tapers and gaskets are used to seal the cooling gas passageway, then the gas seal is improved, but the device complexity and risk of binding increase
Solution Approach 1:
The patent removes the complex precision taper and gasket components from the sealing system. Instead of using traditional tapered interfaces with gaskets, the invention employs a simple flat interface between the electronic module housing and the cooling gas passageway, eliminating the disturbing elements that caused binding and complexity while maintaining gas seal integrity
Solution Approach 2:
The sealing function is separated from the mechanical coupling function. The flat interface provides sealing through a simple planar contact between the module housing and passageway, while the roller mechanism handles the mechanical coupling and positioning, allowing each function to be optimized independently without the complexity of integrated tapered-gasket solutions
2Reliability
If gaskets are used to seal the connection, then the gas seal is improved, but friction and binding occur during insertion and extraction
Solution Approach 1:
The gasket component is completely removed from the system. The patent achieves gas sealing through a flat interface between the electronic module housing and the cooling gas passageway, eliminating the gasket that caused friction and binding during module insertion and extraction operations
Solution Approach 2:
A roller mechanism serves as an intermediary between the module and passageway, allowing smooth insertion and extraction through rolling motion. The roller contacts the module at one location and the passageway at another, mediating the interaction without the friction and binding problems associated with gasket-based sealing
3Reliability
If precision tapers are provided on plug-in electronic modules, then the gas seal is improved, but manufacturing complexity increases
Solution Approach 1:
The precision taper feature is removed from the electronic module design. The patent uses a simple flat interface on the module housing that contacts the cooling gas passageway, eliminating the need for complex precision tapered machining while maintaining effective gas sealing
Solution Approach 2:
The sealing interface geometry is changed from a complex tapered profile to a simple flat planar surface. This parameter change dramatically simplifies manufacturing requirements while maintaining the gas seal function, as flat surfaces are much easier to manufacture with standard tolerances compared to precision tapers
