Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If pluggable optoelectronic transceivers are immersed in cooling fluid for heat dissipation, then heat dissipation performance is improved, but cooling fluid penetration into the transceiver occurs

Engineering Contradiction:

Improveheat dissipation performanceVSAvoidcooling fluid penetration prevention

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The transceiver housing is divided into multiple sealed compartments (optical module accommodation subspace, optoelectronic transceiver module accommodation subspace, actuator accommodation subspace) separated by partition walls. Each compartment is independently sealed to prevent cooling fluid penetration while allowing heat dissipation in designated areas.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A fluid separating colloid is introduced as an intermediary substance that fills the space between the optical module and the housing wall. This colloid acts as a barrier medium that prevents cooling fluid from penetrating into the optical module accommodation subspace while maintaining thermal contact for heat dissipation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Temperature

If cooling fluid is used for heat dissipation, then operating temperature is maintained, but light beam propagation is affected

Engineering Contradiction:

Core Design Contradiction:

TemperatureVSIllumination intensity

Solution Approach 1:

The housing is segmented to create a dedicated light beam propagation space that is physically isolated from the cooling fluid. The optical module accommodation subspace is sealed off from the cooling fluid environment, ensuring that light beams can propagate without interference from the cooling fluid while the surrounding areas handle heat dissipation.

Inventive Principle:

If the transceiver is sealed to prevent cooling fluid ingress, then reliability is improved, but heat dissipation efficiency deteriorates

Engineering Contradiction:

Improvecooling fluid ingress preventionVSAvoidheat dissipation efficiency

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The housing is divided into multiple sealed compartments, each with specific functions. The optical module accommodation subspace is sealed for reliability, while other compartments allow controlled thermal interaction with the cooling fluid, thus maintaining both reliability and heat dissipation efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fluid separating colloid serves as a thermal intermediary that allows heat transfer from the optical module to the housing wall while preventing direct contact with cooling fluid. This mediator enables thermal management without compromising the sealed environment needed for reliability.

AI summary

This is a type of pluggable optoelectronic transceiver that operates while immersed in cooling fluid for data transmission. The pluggable optoelectronic transceiver consists of an optical module, fluid separating colloid, and colloid separating cover. The fluid separating colloid serves to keep the cooling fluid separate from the optical module, while the colloid separating cover further ensures separation between the fluid separating colloid and the optical module. This design prevents the cooling fluid and the fluid separating colloid from infiltrating the optical module and affecting its operation.
