Solution Overview

Problem

Current lightning protection systems, particularly electromagnetic field compensators, lack a method for continuous monitoring and diagnostics to ensure their operational effectiveness and detect potential failures, which can lead to inadequate protection during intense storms.

Innovation Solution

A current intensity measuring device, such as a toroidal current transformer with data transmission and display capabilities, is integrated into the lightning protection system to continuously monitor drainage currents and generate alarms for maintenance or protection, allowing for real-time data recording and analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electromagnetic field compensators are used to prevent lightning strikes, then equipment protection is improved, but the ability to monitor device operation and detect failures is insufficient

Engineering Contradiction:
Improveequipment protectionVSAvoiddevice operation monitoring
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements a feedback mechanism by integrating a current meter that continuously measures drainage current and provides real-time data about the electromagnetic field compensator's operation. This allows the system to self-monitor and alert operators to potential failures, resolving the contradiction between providing protection and being able to detect operational status.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The current meter enables the lightning protection device to self-diagnose its operational status by automatically measuring and recording drainage current values. The system serves itself by providing continuous monitoring without requiring external inspection, thus improving both reliability and detectability simultaneously.

Inventive Principle:
Principle #25Self-service

2Difficulty of detecting and measuring

If continuous monitoring of drainage current is implemented, then device diagnostics are improved, but device complexity increases

Engineering Contradiction:
Improvedevice diagnosticsVSAvoidsystem structure
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent introduces a current meter as an intermediary component that simplifies the monitoring function. Rather than implementing complex diagnostic systems, the current meter serves as a dedicated intermediate device that measures drainage current and provides clear diagnostic information, thus improving diagnostics while adding only minimal complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual inspection methods with electronic current measurement. Instead of physically examining the device or using complex diagnostic equipment, the system uses electrical measurement of drainage current to assess operational status, substituting mechanical/manual processes with simpler electronic sensing.

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

3Loss of information

If current meter is integrated into the lightning protection device, then real-time data collection is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveoperational data collectionVSAvoiddevice assembly
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The patent merges the current meter with the existing lightning protection device structure. By integrating the measurement function into the same housing and mounting system already designed for the electromagnetic field compensator, the patent minimizes additional manufacturing steps while achieving continuous data collection.

Inventive Principle:
Principle #5Merging (Combining)
