Innovation Solution
A fully articulating 40 mm multi-shot launcher with a solenoid-controlled firing system, integrated target acquisition systems including infrared and red laser, and onboard camera, mounted on a gimbal assembly for 360-degree horizontal and 180-degree vertical rotation, made of lightweight materials for drone and robot compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing 40 mm projectile launchers are used, then they can fire 40 mm rounds, but they are not capable of multi-shot systems and are too heavy for attachment to drones
Solution Approach 1:
The launcher is divided into multiple individual barrels (multi-barrel configuration) rather than a single barrel system. Each barrel can be independently loaded and fired, enabling multi-shot capability while keeping each individual barrel lightweight for drone attachment.
Solution Approach 2:
Each barrel is designed with localized loading mechanisms and firing pins, allowing independent operation of each barrel. This segmentation of functionality enables the system to fire multiple rounds while maintaining lightweight construction suitable for mobile platforms.
2Speed
If existing 40 mm projectile launchers are used, then they can fire rounds, but they are not capable of articulating to quickly acquire targets
Solution Approach 1:
The launcher incorporates articulation mechanisms that enable dynamic movement and positioning of the barrels. This allows the system to quickly adjust its aim and acquire targets rapidly while maintaining a relatively simple overall structure suitable for mobile deployment.
3Adaptability or versatility
If existing 40 mm projectile launchers are used, then they can fire rounds, but they lack integrated target acquisition systems
Solution Approach 1:
The launcher integrates multiple target acquisition systems (infrared laser, red laser, and camera) into a single unified platform. This merging of different sensing and targeting technologies provides comprehensive target acquisition capability while sharing common mounting structures and control systems.
Solution Approach 2:
The launcher incorporates multiple types of targeting systems (infrared laser for thermal detection, red laser for visible targeting, and camera for visual confirmation) that can be used independently or in combination, providing universal target acquisition capability across different operational conditions.
4Weight of moving object
If a lightweight launcher is designed for drone attachment, then it can be carried by drones, but it may lack the structural integrity for rapid articulation and multi-shot capability
Solution Approach 1:
The launcher utilizes composite materials and optimized structural design to achieve high strength-to-weight ratio. This allows the construction of a lightweight launcher suitable for drone attachment while maintaining the structural integrity necessary for rapid articulation and withstanding the stresses of multi-shot firing.

AI summary
A multi-projectile launcher capable of firing less-lethal 40 mm rounds or high explosive 40 mm rounds (i.e., HE Grenades) can be attached to robots, drones, vehicles and stationary structures. The robot/drone multi-projectile launcher is remote controlled and capable of 360 degree horizontal rotation as well as vertical panning, and is able to quickly turn and acquire targets. A solenoid controlled firing system for each barrel includes a firing pin, trigger lever and striker, as well as a lockout bar and striker seer to prevent accidental firing (e.g., from impact or sudden jolt). Target acquisition systems include an infrared laser system, a standard red laser system, and an optic targeting system that is monitored through an onboard camera. A wireless network access device allows for remote viewing of live-feed camera images (still frame and video) and control of the optic targeting system, as well as the launcher articulation and firing.
