Solution Overview

Problem

Network devices, such as wireless access points, often fail due to heat buildup without proper ventilation, as they are typically attached to installation surfaces without adequate heat dissipation methods.

Innovation Solution

A mounting socket system that incorporates a heat-conducting socket with a top and bottom portion, allowing the network device to be inserted from one side of the installation surface, where the socket dissipates heat to the opposite side, utilizing heat-conducting materials like aluminum and featuring fingers and flanges to draw heat away from the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network device is attached directly to the installation surface using straps or brackets, then the device is securely mounted, but heat buildup causes the device to fail

Engineering Contradiction:
Improvedevice operational reliabilityVSAvoiddevice temperature
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The patent introduces a mounting socket as an intermediary component between the network device and the installation surface. This socket includes a heat-conducting member that contacts the device and a heat-dissipating member that extends to the installation surface, serving as a thermal bridge to transfer heat away from the device while maintaining secure mounting.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful effect of heat buildup into a beneficial thermal conduction path. By incorporating heat-conducting materials in the mounting socket, the previously problematic heat is channeled through the mounting structure to the installation surface, transforming the mounting system from a heat-trapping element into an active heat-dissipation mechanism.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Temperature

If the network device is disposed at a safe distance from the installation surface to provide ventilation, then heat dissipation is improved, but the mounting security and stability are reduced

Engineering Contradiction:
Improvedevice temperatureVSAvoidmounting strength
Core Design Contradiction:
TemperatureVSStrength

Solution Approach 1:

The patent transitions from a single-dimensional mounting approach (direct attachment) to a multi-dimensional thermal management system. The mounting socket extends thermally in multiple directions - contacting the device internally while dissipating heat externally to the installation surface - creating a three-dimensional heat conduction pathway that maintains both thermal performance and mechanical strength.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If traditional mounting methods are used without heat dissipation features, then the mounting structure is simple, but the device experiences overheating and failure

Engineering Contradiction:
Improvemounting structure complexityVSAvoiddevice operational reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The mounting socket is designed to perform multiple functions simultaneously: mechanical mounting of the device, thermal conduction from the device, and heat dissipation to the installation surface. This multi-functional design integrates mounting and thermal management into a single component, avoiding the need for separate ventilation structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A socket for mounting a network device is provided. The socket includes a top portion and a bottom portion. The top portion and bottom portion are sized to engage with a network communication device that may be inserted into an interior of the socket from a first side of an installation surface. The top portion and bottom portion may be operable to draw heat away from the network device and release the heat on a second side of the installation surface.
