Solution Overview
Problem
Existing colour marker projectiles face challenges in achieving precise and accurate hits due to complex manufacturing and handling issues, leading to imprecise marking of targets, and often result in paint leakage or inefficient colour dispersion upon impact.
Innovation Solution
A colour marker projectile design featuring a front part made of high-density polyethylene with vertical ribs, a thermoplastic polyurethane rubber element for stabilizing flight, and an adhesive colour filler, which ensures efficient colour dispersion and adherence to the target, along with a self-loading mechanism enabled by a conversion kit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex multi-component projectile assembly is used to achieve accurate hits, then manufacturing complexity increases and handling becomes difficult, but accuracy and ballistic stability improve
Solution Approach 1:
The projectile is divided into distinct functional segments: a front part with vertical ribs for stability, a rear part for sealing and gas containment, and an inserted element for spin stabilization. Each segment is manufactured separately and then assembled, allowing for optimized manufacturing of each component while maintaining overall accuracy.
Solution Approach 2:
The inserted element is nested within the front part of the projectile, and the colour filler is contained within the front part. This nested arrangement reduces the overall number of external components, simplifies handling, and maintains the ballistic stability provided by the inserted element without requiring separate external stabilization structures.
2Manufacturing precision
If the projectile structure is made loose to allow colour dispersion on impact, then colour marking effectiveness improves, but paint leakage during operation increases and safety decreases
Solution Approach 1:
The sealing ring is pre-installed on the rear part of the projectile, and the inserted element is pre-positioned in the front part. This preliminary assembly ensures that sealing structures are already in place before impact, preventing paint leakage during operation while allowing controlled colour dispersion upon impact when the projectile detonates.
Solution Approach 2:
The sealing ring acts as an intermediary element between the rear part and the barrel, preventing paint and gas leakage during operation. The inserted element serves as an intermediary that enables spin stabilization and controlled colour release on impact without causing premature leakage. These intermediary components mediate between the conflicting requirements of sealing and colour dispersion.
3Stability of the object's composition
If the projectile uses a rigid structure to maintain structural integrity during flight, then ballistic stability improves, but colour filler spillage on impact is reduced, lowering marking effectiveness
Solution Approach 1:
The projectile transitions from a rigid structure during flight to a dynamic state upon impact. The inserted element is designed to spin the projectile during flight for stability, then upon impact the structure allows the colour filler to spill out. The vertical ribs on the front part provide rigidity during flight but are designed to fail or open upon impact, allowing colour release while maintaining ballistic stability during the flight phase.
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
The solution enhances the ballistic stability and accuracy of colour marking, resulting in a significantly improved and controlled paint stain on the target, with the rubber element ensuring the projectile's structural integrity and preventing paint leakage during operation.
Implementation Method 1
Its shape makes it possible for the colour filler 4, the front part 1 and the inserted element 3 to spin at the same speed, which enables a stable flight of the entire projectile
Implementation Method 2
The colour filler 4 has adhesive properties in order to better adhere to the target as it spills
Implementation Method 3
The front part 1 is formed from a hemispherical and a cylindrical section made out of high-density polyethylene ((PEHD)... The lower part of the cylindrically-shaped section of the front part 1 comprises a groove 1b which is locked with a ring 2a of the rear part 2, which makes it tight and prevents the colour filler 4 to leak out
Implementation Method 4
The rear part 2 also comprises a sealing ring 2b for sealing gases between the barrel and the projectile

AI summary
The subject matter of this invention is a colour marker projectile, intended as a non-lethal projectile to mark a hit with colour which is located in the projectile itself and is poured over the target on impact. The projectile is launched from a conversion kit (new barrel and bolt) of a real weapon. The colour marker projectile according to the invention is made out of a front part (1), a rear part (2), an inserted element (3) and a colour filler (4), whereby the front part (1) is formed as a semicircular cylindrical part with vertical ribs (1a), while the colour filler (4) and the element (3) placed so as to complete the concluded cylindrical part of the front part (1) are located on the inside of the front part (1), and the colour filler (4) is located at the contact point between the front part (1) and the rear part (2).
