Innovation Solution
An illumining projectile system comprising a hollow case, a projectile assembly with a transparent frusto-conical section, a frangible sabot, an explosive propellant charge, an illumining assembly with light sources, and an electrical assembly including a sensor, timer, and controller, which activates illumination after firing or impact, optionally with radio frequency control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a projectile is launched from a distance to illuminate a structure or training area, then safety and convenience are improved, but existing lighting systems cannot provide controlled time delay illumination
Solution Approach 1:
The illumination system is segmented into separate functional modules: a projectile delivery system that can be launched from distance, and an illumination device contained within the projectile. This segmentation allows the projectile to serve as both the delivery mechanism and the illumination source, enabling controlled time delay illumination that existing lighting systems cannot provide.
Solution Approach 2:
The projectile acts as an intermediary carrier between the launch system and the illumination function. It transports the illumination device to the target area and provides the time delay mechanism that bridges the gap between launch and illumination activation, solving the problem of controlled time delay capability.
2Object-affected harmful factors
If illumination is provided from a distance using a projectile, then safety is improved, but device complexity increases due to multiple components
Solution Approach 1:
The patent merges multiple functions into the projectile: it serves as the launch vehicle, the containment structure for the illumination device, and the time delay mechanism. This consolidation reduces overall system complexity compared to having separate delivery and illumination systems, while maintaining safety benefits of distance illumination.
Solution Approach 2:
The projectile is designed with multi-functionality, serving as both the delivery mechanism and the housing for the illumination device. This universal design reduces the need for additional separate components, thereby reducing device complexity while achieving safe distance illumination.
3Strength
If a transparent rigid material is used for the projectile, then durability and reusability are improved, but manufacturing cost may increase
Solution Approach 1:
The patent specifies transparent rigid materials with particular properties (transparency, rigidity, durability) to enable the projectile to withstand launch forces and protect internal components. By carefully selecting materials that meet these parameter requirements, the system achieves durability and potential reusability while controlling manufacturing costs through targeted material specification rather than using premium materials throughout.

Function Achieved in This Case
Enables safe, convenient, and reliable illumination of structures or training areas from a distance, providing a reusable and durable tactical munition for military and law enforcement use, with the ability to be used multiple times and at low cost.
Implementation Method 1
A firing assembly includes an explosive propellant charge
Implementation Method 2
The movements caused when firing the projectile from the case activates the sensor which activates the controller
Implementation Method 3
a timer, and a controller. The movements caused when firing the projectile from the case activates the sensor which activates the controller to illuminate the sources of illumination following a passage of time as determined by the timer
