Innovation Solution

A ballistic slug system that captures bullets from firearms, converting them into less lethal projectiles while maintaining firearm safety and usability, and allows immediate return to lethal state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If entirely new less-lethal tools are created, then less-lethal capability is provided, but the number of tools officers must carry increases and safety is compromised

Engineering Contradiction:
Improveless-lethal capabilityVSAvoidnumber of tools
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ballistic slug adapter enables a single firearm to perform both lethal and less-lethal functions by accepting different types of projectiles (bullets and slugs). The adapter itself is a universal interface that can be attached to various firearms, providing less-lethal capability without requiring separate dedicated less-lethal weapons for each officer.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines lethal and less-lethal capabilities into a single firearm system through the adapter mechanism. The adapter merges the function of a lethal firearm with less-lethal projectile delivery, allowing officers to carry one tool that can deliver both types of ammunition rather than requiring separate weapons.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If entirely new less-lethal tools are created, then less-lethal capability is provided, but officer safety is compromised

Engineering Contradiction:
Improveless-lethal capabilityVSAvoidofficer safety
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The firearm adapter provides universal access to both lethal and less-lethal capabilities through a single reliable platform. Officers can immediately switch between bullet and slug modes without transitioning between different weapon systems, ensuring that lethal force remains immediately available if less-lethal options prove ineffective.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a firearm is converted to less-lethal mode, then less-lethal capability is provided, but the ability to immediately return to lethal state is lost

Engineering Contradiction:
Improveless-lethal capabilityVSAvoidresponse time
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The adapter system is designed to be dynamically reconfigurable. The adapter can be quickly removed or repositioned to allow immediate transition from less-lethal slug mode back to lethal bullet mode. This dynamic design enables officers to adapt their force level in real-time based on the evolving situation without being locked into a single mode.

Inventive Principle:
Principle #15Dynamics

4Strength

If mounting holes with tapered sidewalls are used, then the mounting device secures firmly to the firearm, but manufacturing precision requirements increase

Engineering Contradiction:
Improvemounting securityVSAvoidtaper angle precision
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The mounting holes are designed with specific taper angle parameters (first apex angle and second apex angle) that optimize both security and manufacturability. By carefully selecting and standardizing these angular parameters, the design achieves strong mechanical engagement while remaining compatible with conventional manufacturing processes. The tapered geometry provides self-centering and secure retention without requiring ultra-precise tolerances.

Inventive Principle:
Principle #35Parameter changes

AI summary

The inventive subject matter is directed to systems and apparatuses that are designed to work in cooperation with a firearm such that the firearm can fire a less lethal projectile. Systems can include a mounting device that clips onto a firearm, where that mounting device also include mounting posts. The mounting posts protrude from an end of the mounting device, and the mounting posts are designed to couple with mounting holes on an associated slug. Slugs of the inventive subject matter thus feature mounting holes and a center-bored hole that is designed to capture a bullet that is fired from a firearm that the system is coupled to. When a bullet is captured by a slug, an inelastic collision takes place that causes the slug to leave the firearm at around 20% of the bullet's original speed.
