Solution Overview

Problem

Traditional electromagnetic launchers face safety and reliability issues due to high power consumption and large size, which limits their application in confined spaces and requires significant electric power with potential interference with other equipment.

Innovation Solution

An electromagnetic launcher with a closed-loop guideway, such as a circular or spiral shape, that uses conductive coils to create an electromagnetic field for accelerating projectiles, allowing for higher speeds with reduced power consumption and compact design by maintaining the projectile within the guideway for a longer duration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If traditional electromagnetic propulsion methods are used to achieve high velocities, then projectile speed is improved, but power consumption increases and device size expands

Engineering Contradiction:
Improveprojectile velocityVSAvoidpower consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent employs a circular guideway configuration where the projectile travels along a curved path rather than a straight line. This curvature allows the electromagnetic launcher to recycle the projectile multiple times through the same guideway, effectively multiplying the acceleration benefit without proportionally increasing power consumption or device size.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The circular guideway enables continuous acceleration cycles where the projectile repeatedly passes through the electromagnetic field. This continuous action allows the system to maintain high velocities over time without requiring proportionally increasing power input, as the same electromagnetic field is reused across multiple acceleration cycles.

Inventive Principle:
Principle #20Continuity of useful action

2Speed

If traditional electromagnetic launchers are designed to achieve high velocities, then projectile speed is improved, but device volume increases due to long barrel lengths and large capacitor banks

Engineering Contradiction:
Improveprojectile velocityVSAvoidlauncher size
Core Design Contradiction:
SpeedVSVolume of moving object

Solution Approach 1:

By transitioning from a linear barrel to a circular guideway, the patent compactes the acceleration path into a confined spatial footprint. The curved configuration allows the projectile to traverse a longer effective acceleration path while occupying minimal external volume, eliminating the need for long barrels and large capacitor banks.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The circular guideway design nests the acceleration path within a compact toroidal or circular structure, allowing the projectile to complete multiple acceleration cycles within the same physical envelope. This nesting effect enables high velocities to be achieved without proportionally increasing the overall device volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Speed

If traditional electromagnetic launchers are used, then high velocities are achieved, but safety and reliability issues arise due to high power requirements and electromagnetic interference

Engineering Contradiction:
Improveprojectile velocityVSAvoidsafety and operational reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The circular guideway system employs periodic activation of electromagnetic fields as the projectile passes through different segments of the circle. This periodic action allows for controlled, pulsed acceleration that reduces peak power demands and minimizes electromagnetic interference compared to continuous high-power operation, thereby improving safety and reliability.

Inventive Principle:
Principle #19Periodic action

AI summary

An electromagnetic launcher with a closed-loop guideway and conductors for launching a projectile. The projectile is accelerated along the guideway using electromagnetic forces until it reaches a desired speed, then the projectile is launched in a desired direction. The direction of the launch of the projectile is determined by orienting the guideway in the desired direction using an actuator. The guideway may include a door or aperture allowing the projectile to be launched therefrom, tangent to the curvature of the guideway.
