Problem

Current methods for transferring information between utility meters and electronic consumer devices are inefficient, particularly during installation and maintenance, leading to potential errors and increased costs due to manual data entry and limited access control.

Innovation Solution

A method using an electronic consumer communication device to receive status data from a utility meter, pair virtual and physical addresses, and provide restricted access levels, allowing for efficient data transfer and improved maintenance through an app that utilizes a database and secure access control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual data entry and transfer methods are used between utility meters and consumer devices, then device complexity is reduced, but productivity and reliability deteriorate due to errors and inefficiency

Engineering Contradiction:
Improveinstallation and maintenance efficiencyVSAvoiddata transfer system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a mobile device as an intermediary between the utility meter and the central system. The mobile device receives data from the meter via NFC, stores it locally, and then transfers it to the central system, eliminating the need for direct complex communication infrastructure between meters and the central system while improving data collection efficiency and accuracy

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a copy of the meter data in the mobile device's local database before transferring to the central system. This copying mechanism allows for offline data collection, error verification, and efficient batch processing, significantly improving productivity without requiring continuous complex network connectivity

Inventive Principle:
Principle #26Copying

2Ease of operation

If unrestricted access to meter parameters is provided, then ease of operation improves, but reliability and security worsen due to unauthorized access and potential errors

Engineering Contradiction:
Improveparameter access convenienceVSAvoiddata access security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements different access levels and authorization mechanisms for different parameters and user roles. The mobile application provides tailored interfaces and access rights based on user credentials, allowing convenient access to authorized parameters while restricting access to sensitive data, thus maintaining both ease of operation for legitimate users and security against unauthorized access

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system provides feedback mechanisms including confirmation dialogs before critical operations, error messages for unauthorized access attempts, and audit trails that track parameter access and modifications. This feedback loop ensures reliable operation by preventing erroneous changes while maintaining user convenience through guided interaction

Inventive Principle:
Principle #23Feedback

3Productivity

If virtual address pairing with physical addresses is automated, then productivity improves, but device complexity increases due to address management requirements

Engineering Contradiction:
Improveinstallation speedVSAvoidaddress list management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent pre-loads physical address lists into the mobile device before field installation. During installation, the system automatically matches the meter's virtual address with the pre-stored physical address, eliminating manual data entry and significantly improving installation speed. The address management complexity is shifted to the preparation phase rather than the execution phase

Inventive Principle:
Principle #10Preliminary action
