Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face challenges in achieving reliable and efficient electrical connections, particularly in environments where connector pins need to provide both mechanical and gas-tight seals while accommodating varying receptacle diameters and ensuring high-frequency signal integrity.
Innovation Solution
The development of a double action compliant connector pin with arched flexure elements that provide multiple points of contact, allowing compliance with the receptacle's inner surface to establish a gas-tight and mechanical connection, and featuring a unique aperture design to minimize impedance discontinuities and facilitate high-frequency signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single contact portion is used in the connector pin, then the device complexity is reduced, but the reliability of electrical connection and gas-tight seal is insufficient
Solution Approach 1:
The connector pin is divided into multiple contact portions (first contact portion with first arched flexure element, second contact portion with second arched flexure element) that independently engage with different regions of the receptacle. This segmentation allows each contact portion to independently ensure electrical connection and gas-tight seal, thereby improving overall reliability without requiring a single complex contact mechanism
2Adaptability or versatility
If the connector pin is designed to accommodate varying receptacle diameters, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The connector pin incorporates arched flexure elements that provide dynamic compliance capability. These flexure elements can elastically deform to accommodate variations in receptacle inner diameter, allowing the connector pin to adapt to different receptacle sizes without requiring extremely tight manufacturing tolerances. The dynamic flexibility compensates for dimensional variations in the receptacle
3Reliability
If multiple contact portions are added to the connector pin, then the gas-tight seal and mechanical connection are improved, but the device complexity increases
Solution Approach 1:
The connector pin uses flexible arched flexure elements as thin film structures that can elastically deform to conform to the receptacle inner surface. These flexible elements provide both mechanical connection and gas-tight seal through their compliance capability, achieving reliable sealing without requiring complex multi-component assemblies. The flexible nature of the arched elements allows them to maintain contact pressure and seal integrity
4Reliability
If the aperture is designed to minimize impedance discontinuities, then the high-frequency signal transmission is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The aperture dimensions and geometry are specifically optimized to control impedance characteristics. By carefully selecting aperture parameters (size, shape, position relative to flexure elements), the design minimizes impedance discontinuities that would affect high-frequency signal transmission. This parameter optimization allows achieving good signal integrity without requiring extremely tight manufacturing tolerances on the aperture itself
