Solution Overview

Problem

Current RJ-45 environmental ports in consoles and network monitoring interface cards are not compatible with RJ-12 connectors used by global standard sensor devices, limiting the compatibility and remote management of sensor equipment.

Innovation Solution

An adapter apparatus with RJ-45 and RJ-12 connectors is developed, allowing RJ-12 sensor devices to connect to RJ-45 compatible base devices, facilitating power and data exchange through power supply, data, and ground contacts, and incorporating modular firmware for communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If new board development is performed to support RJ-12 sensors, then compatibility with RJ-12 sensor devices is improved, but development time and cost increase

Engineering Contradiction:
Improvecompatibility with RJ-12 sensor devicesVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The compatibility solution is segmented into a separate, standalone adapter device rather than integrating RJ-12 support directly into the base device's motherboard. This segmentation allows the base device to maintain its RJ-45 design while the adapter handles the RJ-12 connectivity. The adapter can be independently manufactured, tested, and deployed without requiring new board development cycles for the base device.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If new board development is performed to support RJ-12 sensors, then compatibility with RJ-12 sensor devices is improved, but manufacturing cost increases

Engineering Contradiction:
Improvecompatibility with RJ-12 sensor devicesVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By using an adapter as an intermediary, the costly task of modifying base device hardware is avoided. The adapter is a separate, lower-cost component that can be manufactured using standard connector inventory (RJ-45 and RJ-12 connectors are widely available). This approach transfers the compatibility burden from expensive base device re-engineering to a inexpensive peripheral accessory.

Inventive Principle:
Principle #24Intermediary (Mediator)
