Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable-based automatic test equipment systems are used, then electrical connection is established, but significant time is required for calibration and performance issues occur upon reinstallation
Solution Approach 1:
The system is divided into modular components including interchangeable test adapters and receiver modules with standardized interfaces. Each module can be independently calibrated and replaced without affecting other components, eliminating the need for system-wide recalibration when adapters are exchanged.
Solution Approach 2:
The patent implements universal receiver modules that can accommodate multiple types of test adapters through standardized interfaces. This multi-functionality allows different test adapters to work with the same receiver without requiring recalibration, as the standardized interface ensures consistent electrical and mechanical engagement across all adapter-receiver pairs.
2Ease of manufacture
If mass interconnect systems are used to eliminate conventional wiring harnesses, then connectivity is enhanced and wiring costs are reduced, but precise alignment of receiver contacts and test adapter contacts is required to minimize wear and equipment damage
Solution Approach 1:
The test adapter and receiver modules employ asymmetric mechanical features including guide pins, cam slots, and roller pins that are strategically positioned to provide self-alignment during the connection process. These asymmetric elements guide the mating components into precise alignment automatically, eliminating the need for high-precision manual alignment while reducing wear on contact surfaces.
3Adaptability or versatility
If interchangeable test adapters are placed in operative engagement with receiver modules, then testing flexibility is improved, but wear and equipment damage increase without proper alignment mechanisms
Solution Approach 1:
The connection mechanism incorporates dynamic elements including cam slots that convert linear motion into rotational motion of roller pins, and spring-loaded contacts that maintain optimal contact pressure. These dynamic features allow the adapter and receiver to self-adjust during engagement, distributing wear evenly across multiple contact points and preventing localized damage while maintaining reliable electrical connection.

AI summary
A hybrid mass interconnect system and universal pull-through receiver are shown and described. In one embodiment, a universal receiver for a mass interconnect system includes a frame, a connection assembly and a universal interconnect module. Typically, the receiver supports a variety of testing platforms, including PXI-based platforms, LXI-based platforms, AXIe-based platforms, and a combination thereof. In other examples, a variety of other platform relationships may be used. In particular examples, the universal interconnect module has an upper tier with a pair of spatially separated horizontal rails and a lower tier that is adjacent to the upper tier with at least one pair of spatially separated vertical rails. The result is an interconnect system and receiver for enhancing the organizational and interchangeable electrical engagement between a test adapter and automated testing equipment.
