Solution Overview

Problem

Existing Power Line Communication (PLC) technologies, such as the HomePlug AV protocol, face challenges in establishing connections efficiently and accurately, particularly when there is only one electronic device powered on, leading to unnecessary power consumption and electromagnetic interference.

Innovation Solution

The proposed solution involves an electronic device with a data acquiring unit to detect and read preset data from an encryption apparatus using Near Field Communication (NFC), and a connection establishing unit to establish power line communication connections with other devices based on the read data, ensuring secure and rapid pairing of electronic devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing PLC technologies are used to establish connections, then power line communication can be implemented, but connection establishment is slow and inaccurate particularly when only one device is powered on

Engineering Contradiction:

Improveconnection establishment speedVSAvoidconnection accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The encryption apparatus stores preset data (pairing passwords) in advance before connection establishment. When a device is powered on, it can quickly read the preset data from the encryption apparatus without needing to perform complex negotiation procedures, enabling rapid and accurate connection establishment even when only one device is active.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The encryption apparatus acts as an intermediary that holds the pairing passwords. Devices obtain their connection credentials from this intermediary rather than negotiating directly with each other, which streamlines the connection process and improves both speed and accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If manual connection arrangement is required between PLC modules, then connections can be established, but the process is time-consuming and complex

Engineering Contradiction:

Improveconnection setup convenienceVSAvoidmanual operation time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

Devices automatically obtain pairing passwords by reading from the encryption apparatus without requiring manual configuration. The system performs self-service connection setup where devices autonomously acquire the necessary credentials, eliminating time-consuming manual operations.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Pairing passwords are preset in the encryption apparatus in advance. This preliminary preparation allows devices to automatically retrieve credentials without manual intervention, significantly reducing setup time and improving ease of operation.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If connection establishment procedures are simplified, then operation becomes easier, but connection accuracy and security may be compromised

Engineering Contradiction:

Improvepairing process simplicityVSAvoidconnection pairing accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The encryption apparatus serves as a trusted intermediary that securely stores and provides pairing passwords. This intermediary ensures that simplified automatic pairing processes maintain high accuracy and security by relying on pre-configured credentials rather than complex real-time verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Pairing credentials are preset in advance in the encryption apparatus with high precision. This preliminary configuration ensures that even though the pairing process is simplified and automated, the connection accuracy is maintained through pre-validated credentials.

Inventive Principle:

Principle #10Preliminary action
