Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing projectile cores do not allow for simple adjustment of the dividing behavior of projectiles, and they often rely on lead-based materials which are undesirable.
Innovation Solution
A method involving the compression of lead-free wires or wire sections with geometrical shapes and predetermined breaking points to create a cavity-free core, where the dividing behavior is controlled by the number and placement of these breaking points, allowing for customizable division upon impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If lead-free materials are used to produce projectile cores, then environmental safety and health requirements are met, but the material properties and divisibility control are more difficult to achieve
Solution Approach 1:
The core is divided into multiple wire sections, each with specific geometrical shapes (protrusions, recesses, slots) that create predetermined breaking points. This segmentation allows control over how the core divides upon impact while using lead-free material, resolving the contradiction between environmental safety and manufacturability.
Solution Approach 2:
The wire sections are pre-formed with geometrical shapes and predetermined breaking points before being assembled into the core. This preliminary structuring enables precise control of dividing behavior without requiring complex processing of lead-free materials during final core production.
2Adaptability or versatility
If predetermined breaking points are incorporated in the core, then the dividing behavior can be set and controlled, but the core structure becomes more complex
Solution Approach 1:
The core is constructed from multiple wire sections with geometrical shapes that create predetermined breaking points. This segmentation provides controlled dividing behavior while maintaining a relatively simple overall structure based on compressed wire assemblies.
Solution Approach 2:
Geometrical shapes (protrusions, recesses, slots) are placed at specific locations on the wire sections to create predetermined breaking points only where needed. This local structuring achieves dividing control without making the entire core structure complex.
3Manufacturing precision
If wires with geometrical shapes are compressed to form cavity-free core, then the core achieves high density and structural integrity, but the manufacturing process becomes more complex
Solution Approach 1:
Wire sections with geometrical shapes are pre-formed before assembly into the core. This preliminary preparation allows the compression process to focus solely on densification without needing to simultaneously create complex shapes, reducing manufacturing process complexity while achieving high density.
Solution Approach 2:
Multiple wire sections with pre-formed geometrical shapes are assembled and compressed together to form the complete core. This merging approach achieves high density and structural integrity while keeping individual manufacturing steps relatively simple.
