Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional munition guidance systems are costly and technologically difficult to employ, requiring modification of the munition itself, and fail to accurately hit moving targets due to limitations in trajectory calculation and in-flight maneuvering.
Innovation Solution
A munition guidance system comprising a tubular enclosure with guidance wings, a processing and control unit, a target identification unit, and a GPS, which can be mounted as an add-on kit to existing munitions, allowing for erection and maneuvering of wings based on target identification and location data to accurately guide the munition during flight.

Engineering Contradiction Analysis
1Reliability
If conventional guidance systems are used, then guidance capability is provided, but the system becomes costly and technologically difficult to employ requiring modification of the munition itself
Solution Approach 1:
An adaptor device serves as an intermediary component that interfaces between the existing munition and the guidance system. The adaptor includes a connection element that attaches to the munition without requiring structural modifications to the munition itself, while providing mounting surfaces for the guidance system components.
Solution Approach 2:
The adaptor device is designed with universal compatibility to work with multiple types of munitions. The connection element can interface with various munition configurations, and the outer surface can accommodate different guidance system configurations, making the system adaptable without requiring custom modifications for each munition type.
2Measurement precision
If conventional guidance systems are used, then guidance capability is provided, but accurate hitting of moving targets fails due to limitations in trajectory calculation and in-flight maneuvering
Solution Approach 1:
The guidance system employs movable wings that can be dynamically adjusted during flight to alter the munition's trajectory. The wings can be rotated and positioned at different angles to provide real-time course correction, enabling the system to adapt to moving targets and improve hitting accuracy through active maneuvering control.
Solution Approach 2:
The system uses GPS and inertial measurement units to continuously monitor the munition's location and flight parameters. This feedback information is processed by the control unit, which then adjusts the wing positions to correct deviations from the intended trajectory, enabling accurate tracking and interception of moving targets through closed-loop control.
3Stability of the object's composition
If guidance wings are enclosed within the enclosure, then aerodynamic stability is maintained, but the wings cannot maneuver the munition during flight
Solution Approach 1:
The wings are designed to transition from an enclosed, stable configuration to an extended, maneuverable configuration. During flight, the wings can be rotated outward from the enclosure to provide aerodynamic surfaces for course correction, then returned to the enclosed position when maneuvering is complete, thus providing both stability and adaptability at different flight phases.
Solution Approach 2:
The wings are nested within the enclosure when not in use, maintaining a compact and aerodynamically stable profile. When maneuvering is required, the wings are deployed outward from the enclosure, allowing the system to transition between stable flight and active maneuvering modes while protecting the wings when not in operation.

AI summary
A munition guidance system is disclosed. The system comprises a generally tubular enclosure, having an internal cavity adapted for receiving a munition, wherein an outer diameter of the enclosure is at most the largest outer diameter of the munition; and a processing and control unit enclosed within the enclosure and being configured for controlling guidance wings so as to maneuver the munition while flying.
