Solution Overview

Problem

Communication transceivers in electronic devices face increased bit error rates due to high operating temperatures and electrostatic discharge, especially when operating near or exceeding their maximum rated temperature of +85°C, leading to inefficiencies in thermal management.

Innovation Solution

The implementation of a communication transceiver housing with an electrostatic shield and passive cooling features, such as apertures for airflow, maintains the transceiver temperature closer to ambient levels, reducing heat retention and providing electrostatic discharge protection, thus lowering the bit error rate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If communication transceivers operate in extreme temperature settings, then device adaptability is improved, but bit error rate increases due to heat accumulation

Engineering Contradiction:

Improveoperational range in extreme temperaturesVSAvoidbit error rate

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The transceiver housing is divided into two segments: a first segment disposed in a first plane and a second segment disposed in a second plane. This segmentation allows for differentiated thermal management, where the first segment can be exposed to ambient air for cooling while the second segment houses the transceiver components that require temperature control.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a vertical dimension to thermal management by stacking segments in different planes and utilizing airflow from multiple directions. Apertures are positioned to create three-dimensional airflow patterns around the transceiver, enhancing heat dissipation through volumetric air circulation rather than simple linear convection.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If transceiver housing is sealed for protection, then electrostatic discharge protection is improved, but heat retention increases

Engineering Contradiction:

Improveelectrostatic discharge protectionVSAvoidtransceiver temperature

Core Design Contradiction:

Object-affected harmful factorsVSTemperature

Solution Approach 1:

The housing structure implements different properties in different locations: the first and second segments provide electrostatic protection and structural enclosure, while strategically positioned apertures in these segments allow localized airflow access. This creates zones of different functionality - protected zones for ESD and open zones for thermal management.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces air flow as an intermediary medium that passes through apertures in the housing segments. This air flow acts as a heat transfer medium that can remove heat from the transceiver while the housing segments maintain electrostatic protection. The air flow mediates between the need for thermal management and the need for ESD protection.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Disclosed herein are various systems and methods relating to communication devices that include modular transceivers, such as small form pluggable transceivers. According to one embodiment, a communication device may include a chassis defining an interior and an exterior of the communication device. The chassis includes a top, a bottom, and a plurality of sides that together with the top and the bottom form an enclosure. One of the sides may include a first segment disposed in a first plane and a second segment disposed in a second plane. The second segment includes an outwardly extending communication transceiver housing configured to receive a communication transceiver. The communication transceiver may extend through an aperture in the second segment and into interior of the communication device to contact an electrical connector, while a second portion of the communication transceiver in the communication transceiver housing remains on the exterior of the communication device.
