Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Auto-configuration devices often face compatibility issues and resource-intensive pre-configuration challenges when obtaining protocol addresses from network protocol servers, as they may not support all request-response protocols, leading to difficulties in connecting to networks.

Innovation Solution

The auto-configuration device uses information from an Address Resolution Protocol (ARP) request to independently configure its protocol address, allowing it to connect to the network without relying on specific protocols like DHCP, BOOTP, or TR-069, thereby increasing compatibility and conserving computing resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the auto-configuration device uses traditional protocol servers (DHCP, BOOTP, TR-069) to obtain protocol addresses, then the address assignment can be automated, but the device faces compatibility issues and resource-intensive pre-configuration challenges

Engineering Contradiction:

Improveautomatic address configurationVSAvoidprotocol compatibility

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The device monitors multiple network ports simultaneously for ARP requests from different network segments, enabling it to function as a universal auto-configuration device that can obtain addresses from various network topologies without requiring protocol-specific pre-configuration

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device independently monitors its own network ports for ARP requests and autonomously configures its protocol address based on received requests, eliminating the need for external protocol servers and pre-configuration setup

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If the auto-configuration device monitors network ports for ARP requests, then it can independently configure protocol addresses and improve compatibility, but it requires continuous monitoring resources

Engineering Contradiction:

Improvenetwork compatibilityVSAvoidcomputing resource consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The device performs periodic monitoring of network ports for ARP requests rather than continuous active listening, allowing it to maintain network compatibility while conserving computing resources by checking for requests at intervals

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The device uses ARP requests as an intermediary mechanism to passively receive address configuration information from network infrastructure, avoiding the need for active protocol negotiations and reducing computational overhead

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the device requires pre-configuration to support specific protocols, then it can ensure reliable address assignment, but it increases device complexity and preparation time

Engineering Contradiction:

Improveaddress assignment reliabilityVSAvoidpre-configuration requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device automatically detects and responds to ARP requests without requiring pre-configured protocol support, achieving reliable address assignment through self-service operation that eliminates complex pre-configuration steps

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Instead of the device actively requesting addresses from protocol servers, the solution inverts the approach by having the device passively receive and respond to ARP requests that contain address information, simplifying the configuration process

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A device may monitor a network port for an address resolution protocol (ARP) request from a sender device. The device may detect the ARP request based on monitoring the network port for the ARP request. The device may identify a target protocol address included in the ARP request. The device may configure a protocol address of the device using the target protocol address.
