Solution Overview

Problem

Current methods for directing lightning strikes are inefficient and often result in strikes returning to the initiator's location, limiting their application in military and scientific contexts.

Innovation Solution

A lightning direction device comprising a drag member, a pendant mass, and an ungrounded conductor is used to guide lightning strikes away from the initiator, utilizing wind resistance and guidance systems to position the device in a highly charged atmosphere, allowing for directed strikes at desired locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a sounding rocket is used to drag a grounded wire up to a highly charged region in the atmosphere, then the lightning strike can be initiated, but the strike returns to the initiator's location resulting in no beneficial military application

Engineering Contradiction:
Improvelightning strike direction controlVSAvoidstrike location control
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system divides the lightning directing function into separate components: a ballistic object for delivery, a drag member for atmospheric positioning, a conductor for charge collection, and a pendant mass for strike initiation. This segmentation allows the strike to be directed away from the initiator by separating the initiation point from the strike target point.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conductor acts as an intermediary between the highly charged atmospheric region and the ground. By positioning the conductor at a specific location away from the initiator and allowing it to collect charge, the system mediates the lightning strike to occur at the conductor's location rather than returning to the initiator.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If equipment mass is reduced to minimize cost, then the system becomes more economical, but the ability to control and direct lightning strikes may be compromised

Engineering Contradiction:
Improveequipment costVSAvoidlightning strike direction control
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The system uses naturally occurring atmospheric charge as the energy source, eliminating the need for heavy power supplies or complex energy storage systems. The ballistic object itself serves multiple functions: delivery vehicle, positioning mechanism (via drag member), and strike initiator (via pendant mass), reducing overall equipment mass while maintaining reliability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Instead of bringing heavy equipment to the target location to generate or control lightning, the system inverts the approach by delivering a lightweight conductor to collect existing atmospheric charge and use it to initiate strikes. This inversion dramatically reduces equipment mass and cost while maintaining strike direction control capability.

Inventive Principle:
Principle #13The other way round (Inversion)
