Foolproof Home Energy Device Commissioning via Catchphrase Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning process for network-enabled devices is cumbersome for users due to the need to enter meaningless hexadecimal MAC addresses, leading to potential input errors and frustration, especially for non-technical users.
Innovation Solution
Assigning human-language catchphrases composed of common words to network interfaces, allowing users to easily identify and commission devices by entering memorable phrases instead of complex codes, with a centralized or decentralized management system to generate and manage these phrases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MAC addresses or EUI identifiers are used to uniquely identify network interfaces, then device identification precision is improved, but ease of operation deteriorates due to meaningless hexadecimal digits being difficult for users to remember and enter
Solution Approach 1:
The patent introduces a mediator system consisting of a phrase generation server and database that translates between user-friendly phrases and MAC addresses. When a user commissions a device, they enter a meaningful phrase (e.g., 'blue widget') instead of a hexadecimal MAC address. The server acts as an intermediary, receiving the phrase, querying the database to find the corresponding MAC address, and completing the commissioning process. This mediator layer preserves the precision of MAC address identification while eliminating the operational difficulty of entering and remembering hexadecimal codes.
Solution Approach 2:
The patent creates a copy or representation of the MAC address in the form of a human-readable phrase. Instead of requiring users to directly interact with the hexadecimal MAC address, the system generates and stores a corresponding phrase (e.g., converting MAC address '00:1B:44:11:3A:B7' to phrase 'blue widget'). This phrase copy is then used during commissioning, maintaining the unique identification function while dramatically improving user experience by replacing meaningless digits with memorable words.
2Reliability
If conventional commissioning methods using hexadecimal codes are used, then device identification accuracy is maintained, but user frustration and input errors increase
Solution Approach 1:
The patent replaces the mechanical interaction of manually typing hexadecimal codes with an automated phrase-matching system. Instead of the user mechanically entering a long sequence of hexadecimal digits prone to typing errors, the system substitutes this with a simplified process where the user inputs or selects a short phrase, and the server automatically resolves it to the correct MAC address. This substitution eliminates the mechanical error-prone step while maintaining accurate device identification through the backend phrase-to-MAC mapping.
3Ease of operation
If meaningful catchphrases are assigned to network interfaces, then ease of operation is improved, but device complexity increases due to the need for phrase management systems
Solution Approach 1:
The patent extracts the phrase management functionality from the individual network devices and places it in a separate centralized server system. Each device only needs to store its own unique phrase locally, while the complex phrase-to-MAC address mapping, validation, and resolution logic are extracted and housed in the external phrase generation server. This extraction reduces the complexity burden on individual devices, as they no longer need to manage or validate phrases themselves - they simply use their pre-assigned phrase during commissioning, while the server handles all the complex management tasks.

AI summary
A foolproof method of adding network-enabled energy control devices to a home energy device control network by associating an easy-to-remember catchphrase composed of ordinary words with a unique MAC address or EUI identifier of the network-enabled device. The device manufacturer associates a unique catchphrase with each device and stores the catchphrases and associated MAC addresses in a database along with the device information required to commission the device onto the user's network. When the user enters the catchphrase, the catchphrase is sent to the manufacturer's server for retrieving the MAC address and corresponding device information. When a valid catchphrase is entered and accepted, the device can be commissioned onto the user's network.
