Solution Overview

Problem

Identifying and tracking devices such as hydrants and valves in fluid distribution systems is challenging due to their design and harsh operating conditions, which hinder on-site identification, tracking, and documentation.

Innovation Solution

Incorporating a digital identification tag, specifically a radio-frequency identification (RFID) tag, into the operating nut of devices, allowing for engagement with a tool equipped with an RFID tag reader to retrieve and transmit device data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical identification methods or separately affixed labels are used on devices, then device identification is possible, but the identification can wear or become obscured during use

Engineering Contradiction:
Improveidentification reliabilityVSAvoididentification durability
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The RFID tag is embedded within the operating nut itself, nesting the identification technology inside the device component. This ensures the identification system is protected by the nut's structure and cannot wear or become obscured like external labels.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent replaces mechanical identification methods (labels, serial numbers) with electromagnetic RFID technology. This substitution eliminates wear and obscuration issues by using contactless electromagnetic fields for data storage and retrieval.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If devices are buried in deep pits or placed in harsh conditions, then device functionality is maintained, but direct physical inspection and identification become inaccessible

Engineering Contradiction:
Improvedevice operational reliabilityVSAvoidinspection accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces physical inspection requirements with wireless RFID communication. The reader can retrieve device information remotely without requiring physical access to the device, enabling inspection of buried or hard-to-reach equipment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The RFID tag acts as an intermediary that stores and transmits device information wirelessly. This intermediary enables data access without direct physical contact, allowing inspection of devices in inaccessible locations through electromagnetic field communication.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If no unique information is stored on devices, then device simplicity is maintained, but tracking and documentation capabilities are insufficient

Engineering Contradiction:
Improvedevice structural simplicityVSAvoiddevice information availability
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent replaces physical information storage (labels, plates) with electromagnetic RFID tags. This allows substantial information capacity while maintaining external device simplicity, as the RFID tag is compact and integrated into the operating nut.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the state of information storage from external physical media to internal electromagnetic fields. This parameter change enables high information density and durability while keeping the device structure simple and unchanged from traditional designs.

Inventive Principle:
Principle #35Parameter changes
