Fragmenting Projectile with Variable Core Weight for Consistent Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragmenting projectiles lack consistency in point of impact and fragmentation behavior, making it difficult for marksmen to achieve desired fragmentation without compromising projectile weight and geometry.
Innovation Solution
Designing fragmenting projectiles with a fragmentable core in the nose area, where all projectiles of the same type have the same weight, center of gravity, and geometry, with the core's density and weight varying to control fragmentation, and visible markings for selection, such as colored plastic tips or tactile markings, to ensure consistent point of impact and adjustable fragmentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the weight of the fragmentable core is increased to achieve higher fragmentation, then the fragmentation degree is improved, but the overall projectile weight would change affecting the point of impact
Solution Approach 1:
The patent applies parameter changes by systematically varying the weight of the fragmentable core (25%, 40%, 60% of total projectile weight) while compensating with adjustments to the solid core weight. This allows the fragmentable core weight parameter to change for different fragmentation needs while maintaining the total projectile weight parameter constant, thus resolving the contradiction between adaptability of fragmentation degree and consistency of projectile weight.
2Adaptability or versatility
If the weight of the fragmentable core is varied to control fragmentation, then the fragmentation behavior is improved, but the center of gravity and geometry would change affecting the point of impact
Solution Approach 1:
The patent systematically adjusts the weight distribution between fragmentable core and solid core while maintaining constant total weight. By changing the fragmentable core weight parameter (25%, 40%, 60%) and compensating with solid core weight adjustments, the center of gravity position is kept stable. This resolves the contradiction by allowing fragmentation behavior to vary while maintaining compositional stability for consistent point of impact.
3Adaptability or versatility
If different projectile designs are used to achieve different fragmentation, then the fragmentation is improved, but the complexity of selection and identification increases
Solution Approach 1:
The patent uses color-coded markings (green for 25% fragmentable core, black for 40%, red for 60%) to identify different fragmentation options. This visual identification system resolves the contradiction by providing clear, intuitive differentiation between projectile types without requiring complex markings or specifications, making selection simple despite offering multiple fragmentation options.
Solution Approach 2:
The patent segments the projectile into distinct components (fragmentable core and solid core) with clearly defined weight ratios. This segmentation allows for systematic variation of fragmentation characteristics while maintaining a consistent overall structure. The clear segmentation also simplifies identification through external markings, resolving the contradiction between versatility and selection complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables marksmen to select projectiles for desired fragmentation while maintaining consistent point of impact, improving the effectiveness of hunting shots by allowing tailored fragmentation ratios based on animal type and distance.
Implementation Method 1
fragmentable core being arranged in the front nose area with both types of projectiles, all fragmentable cores of one type of projectile have the same density and differing from one another in the weight of the fragmentable core, depending on the fragmentation
Implementation Method 2
a pressed or lathed projectile body is preferably present in the rear area and has a funnel-shaped indentation, on which the fragmentable core sits. This indentation improves the mushroom effect on impact.

AI summary
The invention relates to fragmenting projectiles. In order that all projectiles of a*waffe*Bug projectile type have the same point of impact, i.e., the same projectile weight, the same center of gravity and the same geometry, and that the marksman can set the fragmentation behavior solely by selecting the projectile, fragmenting projectiles having defined fragmentation in steps for the same point of impact, designed as two projectile types, namely as partially fragmenting projectiles or as jacketed projectiles, are proposed, wherein all fragmenting projectiles of a projectile type have the same projectile weight, the same center of gravity, and the same geometry, a fragmentable core is arranged in the front nose region for both projectile types, all fragmentable cores of a projectile type have the same density and differ from each other in the weight of the fragmentable core depending on the fragmentation, and all projectiles of a projectile type having the same weight of the fragmentable core have an identical marking that can be seen or felt from the outside.
