Self-Actuating Protective Cover for FRU Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Field-replaceable units (FRUs) in network systems are prone to connector damage when removed from the chassis, due to exposure to dust, debris, humidity, or mishandling, leading to performance issues.
Innovation Solution
A self-actuating protective cover device is integrated into the FRU, featuring a protective cover linked to a driving and supporting link component, which moves automatically to cover the connectors when the FRU is removed and uncover them for installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connectors are exposed when FRU is removed from chassis, then ease of operation is improved, but reliability deteriorates due to damage from dust, debris, humidity, or mishandling
Solution Approach 1:
The protective cover is positioned to cover the connectors before the FRU is removed from the chassis. The self-actuating mechanism automatically opens the cover when the FRU is installed, so the connectors are protected during removal and transport, then automatically exposed when needed for connection.
Solution Approach 2:
The protective cover device includes a self-actuating mechanism that automatically opens the cover when the FRU is installed in the chassis. The engagement component interacts with the chassis to trigger automatic opening, eliminating the need for manual intervention to expose the connectors.
2Reliability
If protective cover is manually opened, then connector protection is improved, but device complexity increases due to additional manual operations
Solution Approach 1:
The protective cover device includes a self-actuating mechanism that automatically opens the cover when the FRU is installed in the chassis. The engagement component interacts with the chassis to trigger automatic opening, eliminating the need for manual intervention to expose the connectors.
Solution Approach 2:
The protective cover is designed to be movable between closed and open positions. The self-actuating mechanism converts the installation motion into automatic cover opening, making the system dynamic and adaptive to the installation process without requiring separate manual operations.
3Ease of operation
If self-actuating mechanism is added, then ease of operation is improved, but device complexity increases due to additional components
Solution Approach 1:
The engagement component serves multiple functions: it guides the FRU installation, triggers the automatic cover opening, and ensures proper positioning. The driving link and supporting link mechanisms convert the installation motion into cover opening motion, allowing a single installation action to accomplish multiple tasks.
Solution Approach 2:
The protective cover mechanism is integrated with the FRU housing and installation structure. The engagement component, driving link, and supporting link are combined into a compact assembly that works together with the chassis installation process, reducing the need for separate independent mechanisms.

AI summary
A field-replaceable unit (FRU) includes a self-actuating protective cover device that includes: a protective cover, a housing component that includes a slot, a driving link component attached to the protective cover and the housing component, a supporting link component attached to the protective cover and the housing component, and an engagement component attached to the driving link component, wherein the engagement component is to be engaged by an actuation component of a mating connector and caused to move within the slot of the housing component, and the engagement component is to cause the driving link component, the supporting link component, and the protective cover to move when the engagement component moves within the slot of the housing component. The protective cover is to be positioned over one or more connectors of the FRU when the engagement component is positioned at an unengaged position within the slot of the housing component.
