Transceiver Release Mechanism for Sealed Housing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing small form-factor pluggable optical transceivers with levers, stirrups, or straps are too large to be used in dust or waterproof appliances, requiring the housing to be opened for replacement.

Innovation Solution

A device with first and second releasing means allows for the transceiver to be released from the housing without opening it, using a clamp connection and a wedge or hook element to securely lock and release the transceiver, enabling easy replacement from outside the appliance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a transceiver is equipped with a lever, stirrup, or strap for release, then the transceiver can be released from the housing, but the transceiver size becomes too large for dust or waterproof appliances

Engineering Contradiction:

Improvetransceiver release capabilityVSAvoidtransceiver size

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The release mechanism is extracted from the transceiver itself and placed in the housing. The housing now contains the lever or stirrup that interacts with the transceiver's locking contour, allowing release functionality without adding volume to the transceiver component.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

A locking contour on the transceiver serves as an intermediary element that interfaces with the housing's release mechanism. This allows the transceiver to be released without requiring built-in levers or straps, maintaining a compact form factor while enabling easy removal from the housing.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of repair

If the housing is opened to replace the transceiver, then the transceiver can be replaced, but the appliance loses its dust or waterproof protection

Engineering Contradiction:

Improvetransceiver replaceabilityVSAvoiddust or water ingress

Core Design Contradiction:

Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The housing's release mechanism allows the transceiver to be removed and replaced from the outside without opening the housing. The sealed housing structure remains intact, maintaining dust and waterproof protection while enabling easy transceiver replacement through the existing sealed interface.

Inventive Principle:

Principle #25Self-service

3Reliability

If the transceiver is locked in the housing, then the transceiver is securely fixed, but the transceiver cannot be released without opening the housing

Engineering Contradiction:

Improvetransceiver fixationVSAvoidtransceiver release accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism is segmented into two independent parts: a locking contour on the transceiver and a corresponding locking structure in the housing. This segmentation allows the transceiver to be securely locked when inserted while enabling release through the housing's external mechanism without compromising fixation reliability.

Inventive Principle:

Principle #1Segmentation
