Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld rocket launchers face inaccuracies in targeting due to the limitations of traditional sighting devices, requiring operators to fire close to the target and increasing the risk of detection.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sighting devices are used to aim the handheld rocket launcher, then the device complexity is reduced, but the measurement precision of target acquisition deteriorates
Solution Approach 1:
The patent replaces traditional mechanical sighting devices with an electronic targeting system that uses sensors (optical, infrared, radar), processors, and digital calculation modules to determine firing solutions. This substitution of mechanical systems with electronic and computational systems enables precise measurement of target parameters while maintaining manageable device complexity through integrated circuitry and software algorithms.
2Measurement precision
If the operator fires close to the intended target to compensate for aiming inaccuracy, then the measurement precision of target acquisition is maintained, but the object-generated harmful factors increase due to increased detection risk
Solution Approach 1:
The electronic targeting system with multiple sensors and computational algorithms provides accurate target acquisition capability, allowing the operator to engage targets at optimal distances rather than forcing close-range firing. This eliminates the need to fire close to the target as a compensation mechanism for poor aiming precision.
Solution Approach 2:
The system incorporates feedback through multiple sensors that continuously gather information about target parameters, allowing the processor to calculate and adjust the firing solution. This feedback loop ensures accurate targeting while enabling engagement at safer distances that reduce detection risk and operator exposure.
3Measurement precision
If multiple sensors and calculation modules are added to improve targeting accuracy, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The patent integrates multiple sensors (optical, infrared, radar), calculation modules, and control systems into a single unified targeting system. By merging these components into an integrated architecture, the system achieves high measurement precision through multi-parameter sensing while managing device complexity through consolidated design and shared processing resources.
Solution Approach 2:
The targeting system is designed with multi-functional capabilities, where a single integrated system performs multiple functions including target detection, parameter measurement, trajectory calculation, and firing solution determination. This universality allows the system to achieve high precision through multiple sensing modalities without proportionally increasing overall system complexity.

AI summary
In an example embodiment, a method of identifying a firing solution to a target is provided. In this method, an elevation of the target and a height of the target relative to an initial height of the projectile are sensed. A clear line of sight from the projectile to the target is also sensed. Based on the elevation, the height, and the clear line of sight, an acceptable firing solution is identified. An signal indicating that the projectile can be launched can then be initiated based on the identification of the acceptable firing solution.
