Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed telecommunication systems experience diminished signal integrity and performance due to 'de-mate' or 'under-mate' conditions between Physical Interface Cards (PICs) and Flexible PIC Concentrators (FPCs), leading to errors and failures.
Innovation Solution
The use of a housing with a spring-loaded mechanism and movable injection cam that applies force to ensure secure connection between field-replaceable units and telecommunication systems, mitigating air gaps and deficient contacts by pushing the units toward connectors, thereby maintaining signal integrity at high speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If field-replaceable units are connected to telecommunication systems using conventional connectors, then the device complexity is reduced and ease of manufacture is improved, but de-mate or under-mate conditions occur leading to diminished signal integrity at high speeds
Solution Approach 1:
The patent applies a spring-loaded mechanism that dynamically adjusts the connection force between the field-replaceable unit and the telecommunication system. The spring provides continuous pressure to maintain full mating of connectors, compensating for manufacturing tolerances and preventing de-mate conditions that occur with static conventional connectors. This dynamic adjustment ensures reliable signal integrity at high speeds while managing the added complexity through a well-defined mechanical system.
2Reliability
If manufacturing and assembly tolerances are reduced to ensure full connector mating, then signal integrity at high speeds is improved, but manufacturing cost and difficulty increase
Solution Approach 1:
The patent changes the mechanical parameter of connection force by introducing a spring-loaded mechanism. Instead of relying on precise manufacturing tolerances to achieve full connector mating, the spring provides adjustable force that compensates for tolerance variations. This allows standard manufacturing processes to be used while still achieving reliable signal integrity, as the spring force ensures proper contact despite normal manufacturing variations.
3Reliability
If spring-loaded mechanisms with movable injection cams are used to ensure full connector mating, then signal integrity and communication reliability at high speeds are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements preliminary action by pre-loading the spring mechanism to automatically apply force when the field-replaceable unit is inserted. The movable injection cam is positioned to engage with the spring mechanism before final connector contact, ensuring that the spring force is immediately applied to maintain full mating. This preliminary preparation of the mechanical system ensures reliable connection without requiring complex active control systems during operation.

Implementation Method 1
a spring that is coupled to the housing, and a movable injection cam that is coupled to the spring such that, when the field-replaceable unit is installed in the housing by way of an ejection lever that presses against the movable injection cam, the spring applies a force on the movable injection cam that causes the movable injection cam to push the field-replaceable unit toward the connector
