Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing directed fragmentation weapons lack the ability to deliver fragments in a consistent and controlled formation, leading to inefficiencies in target distribution and increased collateral damage, which is a concern for both lethal and non-lethal applications.
Innovation Solution
The design of the directed fragmentation weapon incorporates a pellet matrix construction where the depth of compartments is defined by the equation h=C×A, with C ranging from 0.1 to 3, allowing for precise positioning and consistent fragment distribution, enabling flexible and controlled fragment formation post-detonation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional explosive charge is used without a pellet matrix, then the weapon structure is simpler, but the fragment distribution is uncontrolled and inconsistent
Solution Approach 1:
The front wall is segmented into a pellet matrix construction with multiple compartments, each holding a pellet. This segmentation allows precise control over fragment distribution while maintaining consistent formation across detonations. The compartments are arranged in a grid pattern with specific spacing to achieve uniform fragment projection.
Solution Approach 2:
Pellets are pre-positioned in compartments before detonation occurs. The compartments are formed with specific depths and dimensions to hold pellets in predetermined positions. This preliminary arrangement ensures that when detonation occurs, fragments are distributed in a consistent and controlled formation.
2Manufacturing precision
If compartment depth is increased to improve fragment containment, then fragment distribution consistency improves, but manufacturing complexity increases
Solution Approach 1:
The compartment depth is defined by a specific parameter relationship (h=C×A, where C ranges from 0.1 to 3 and A is the pellet diameter). This parameter-based approach allows optimization of fragment containment while simplifying manufacturing. By expressing depth as a multiple of pellet diameter, the design achieves precise control without requiring absolute depth specifications.
3Manufacturing precision
If a pellet matrix with fixed compartment depths is used, then fragment distribution is more consistent, but adaptability to different pellet sizes is reduced
Solution Approach 1:
The compartment depth is defined as h=C×A, where A is the pellet diameter and C is a coefficient ranging from 0.1 to 3. This parameter relationship allows the compartment depth to scale with pellet size, maintaining optimal fragment containment and distribution consistency across different pellet dimensions. The coefficient C can be adjusted to optimize performance for specific pellet types.

AI summary
Directed fragmentation weapon including a housing having front, back, top edge, bottom edge and side edge walls defining a closed chamber therein. The front wall is formed as a pellet matrix construction including a plurality of compartments formed as recesses on the surface facing the inside of the chamber. The compartments are substantially similar in shape and size to each other and a plurality of pellets of fixed diameter within the matrix. Each compartment contains one pellet therein. Explosive material is placed into the chamber, which is sufficient to propel the pellets from the matrix, and a detonator arrangement for exploding the material. Depths of a part or all of the compartments measured perpendicularly to the front wall and from the inner surface of the front wall are defined by equationh=C×A (I)wherein equation coefficient C is 0.1-3, and A is the pellet diameter.
