Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for intercepting ground targets are ineffective for capturing small targets with low altitude and low velocity in aerial environments.
Innovation Solution
A system comprising a detecting apparatus, directing control apparatus, aiming control apparatus, launch control apparatus, launching device, and intercepting device, which uses laser ranging for real-time measurement of target parameters and performs trajectory calculations to guide an intercepting net that is launched and deployed to ensnare the target, followed by a parachute-assisted descent to the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional net catching systems are used for ground targets, then the capturing capability for ground targets is achieved, but the system is incapable of intercepting aerial targets
Solution Approach 1:
The net catching system is transformed into a multi-functional device that can intercept both ground targets and aerial targets. The launching device adds vertical projection capability to the conventional horizontal net deployment, enabling the same net structure to capture targets in three-dimensional space whether on ground or in air.
Solution Approach 2:
The system transitions from two-dimensional ground-based net deployment to three-dimensional aerial interception by introducing vertical launching capability. The net is projected upward along a predetermined trajectory to intercept aerial targets, adding the vertical dimension to the traditional horizontal net catching operation.
2Speed
If destructive weapons are used for aerial targets, then interception capability is achieved, but the system causes destruction which is unacceptable in city environments
Solution Approach 1:
The system converts the harmful effect of high-velocity impact from destructive weapons into a beneficial gentle capture mechanism. Instead of using kinetic energy to destroy the target, the net uses entanglement and the parachute uses controlled drag to safely decelerate and capture the aerial target without destruction.
Solution Approach 2:
The intercepting net acts as an intermediary between the launching device and the aerial target, providing a non-destructive capture mechanism. The parachute serves as an additional intermediary that controls the descent speed of the captured target, ensuring safe landing without direct impact with the ground.
3Measurement precision
If laser ranging and trajectory calculation are implemented for real-time tracking, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical tracking systems with laser ranging technology for measurement and uses computer-based trajectory calculation algorithms for control. This substitution of mechanical systems with optical and computational systems achieves high measurement precision while managing overall system complexity through electronic control rather than mechanical complexity.

AI summary
A method for intercepting a small target with low altitude and low velocity. The method is realized based on: a detecting apparatus, a directing control apparatus, an aiming control apparatus, a launch control apparatus, a launching device and an intercepting device. The method comprises: searching and tracking a target by the detecting apparatus in a networking mode or by the aiming control apparatus in a single pawn mode; sending target information to the launch control apparatus; performing a trajectory calculation by the launch control apparatus; and launching the intercepting device by the launching device to intercept the target. By launching the intercepting device at a ground to catch an aerial target, a problem that a conventional method for catching a ground target is incapable for catching the aerial target is solved. The method has advantages of low cost, short response time, the remaining load falling in a low velocity, which is applicable for a city environment.
