Modular Hand Grenade with Detachable Hollow Charge Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hand grenades have a limited range of application and are ineffective against armored targets, as they primarily rely on spatial effects rather than focused penetration.
Innovation Solution
A hand grenade design featuring a modular construction with a hollow charge insert, such as a ring-shaped or pointed-cone hollow charge, that can be integrated at the bottom end for enhanced armor-penetrating capabilities, allowing for targeted and deeper penetration into armored targets by expanding the damaged surface area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional hand grenade design is used, then the device is simple and easy to manufacture, but it has limited range of application and cannot effectively penetrate armored targets
Solution Approach 1:
The hand grenade is divided into separate functional modules: a base module containing the explosive charge and a detachable hollow charge insert module. This segmentation allows the hollow charge insert to be added only when armored targets are encountered, enhancing adaptability without permanently complicating the device structure.
Solution Approach 2:
The hand grenade is designed to perform multiple functions: conventional explosive effect with the base module, and armored target penetration with the hollow charge insert module. The universal design allows a single device platform to adapt to different target types by simply attaching or removing the hollow charge insert.
2Strength
If a hollow charge insert is added for armor penetration, then penetration depth and damage area increase, but the device complexity increases
Solution Approach 1:
The hollow charge insert is designed to be nested within the existing hand grenade structure, fitting into the bottom end of the explosive body. This nesting approach allows the penetration function to be integrated without significantly increasing overall device complexity, as the hollow charge insert utilizes the existing spatial framework.
Solution Approach 2:
The hollow charge insert is pre-configured with the appropriate geometry and material properties to maximize penetration effectiveness. By preparing the insert in advance with the correct shape and dimensions, the device achieves high penetration depth without requiring complex in-situ adjustments or modifications during deployment.
3Ease of operation
If a hollow charge insert is integrated at the bottom end, then targeted penetration is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The hollow charge insert is designed with specific local quality characteristics - a concentrated explosive charge arranged in a hollow cone or ring shape at the bottom end of the hand grenade. This local concentration of explosive material provides targeted penetration capability while maintaining relatively simple manufacturing processes compared to requiring precise integration throughout the entire device.

AI summary
Building on a modular construction of a hand grenade (10), the invention provides a module (1) that can be integrated in the hand grenade (10) and can be equipped with a hollow charge insert (3) in order to act as an armor-penetrating part. The module (1), including the hollow charge insert (3), can be fixed (mounted, screwed, clipped, etc.) at the bottom end of the hand grenade (10) and is attached to the armored element. In the simplest form, the hand grenade (10) is put down, in the case of side walls possibly hung on, and the hand grenade (10) is attached so that the hollow charge insert (3) can exert an adequate effect on the target medium.
