Projectile Core Using Agricultural Biomass Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current marking projectiles, such as paintballs, face issues with high manufacturing costs, breakage, accuracy problems due to liquid dye shifting during flight, and environmental impact, particularly with gelatin or starch shells filled with liquid dye, which can cause permanent staining and are not efficiently biodegradable.
Innovation Solution
A novel projectile core formed from a fibrous or powder carrier mixed with a colorant, shaped to retain its form until impact, whereupon it disintegrates or disperses to mark the target, using absorbent materials like rice straw or powders, eliminating the need for a liquid-filled capsule and reducing environmental concerns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gelatin or starch shells filled with liquid dye are used, then the projectile can mark the target, but the manufacturing cost increases and the projectile breaks easily
Solution Approach 1:
The patent replaces expensive gelatin or starch shells with inexpensive agricultural biomass materials such as rice straw, wheat straw, or other plant-based fibrous materials. These materials are abundant, cheap, and biodegradable, eliminating the need for costly synthetic polymers while maintaining the projectile's functional integrity during use.
Solution Approach 2:
The patent creates a composite structure by combining agricultural biomass materials with binding agents and colorants. This composite approach allows the projectile to achieve both structural strength and marking functionality, resolving the contradiction between reliability and manufacturing cost by using naturally occurring materials rather than expensive synthetic alternatives.
2Measurement precision
If liquid dye is used in the projectile, then the target can be marked, but the liquid dye shifts during flight causing accuracy problems
Solution Approach 1:
The patent changes the physical state of the dye from liquid to solid or semi-solid form by incorporating it into the agricultural biomass matrix. This parameter change prevents the dye from shifting during flight, thereby improving marking accuracy while maintaining the biodegradable and environmentally friendly characteristics of the projectile.
Solution Approach 2:
The patent integrates the colorant into the agricultural biomass composite material, creating a unified structure where the dye cannot move independently. This composite approach ensures the dye remains in its designated position throughout flight, solving the accuracy problem while preserving the environmental benefits of natural materials.
3Strength
If gelatin or starch shells are used, then the projectile can survive loading and firing forces, but the shells are expensive and time-consuming to produce
Solution Approach 1:
The patent replaces time-consuming gelatin or starch shell production with rapid processing of agricultural biomass materials. These natural materials can be processed quickly through simple formatting and binding operations, dramatically improving manufacturing efficiency while maintaining sufficient strength to withstand loading and firing forces.
Solution Approach 2:
The patent changes the material properties by using naturally strong agricultural biomass materials that require minimal processing. These materials maintain structural integrity through their natural fiber structure rather than requiring complex synthetic polymer formation, thereby reducing manufacturing time and improving productivity without sacrificing impact resistance.
4Reliability
If conventional liquid dye compositions are used, then the projectile can mark the target, but the dye causes permanent staining and freezing issues
Solution Approach 1:
The patent changes the chemical composition parameters of the dye system by using natural pigments and colorants derived from agricultural materials rather than synthetic liquid dyes. These natural alternatives maintain effective marking capability while eliminating harmful properties such as permanent staining and freezing at low temperatures, as they are biodegradable and environmentally compatible.
Solution Approach 2:
The patent employs biodegradable agricultural biomass materials that naturally decompose after use, eliminating the need for harsh chemical cleaners to remove staining. The natural materials break down harmlessly in the environment, avoiding the freezing and staining issues associated with conventional synthetic dyes, while maintaining effective marking performance.

AI summary
A projectile core is provided formed from a carrier and a colorant. The carrier and colorant are mixed into a core mixture, which is formed into a predetermined core shape. The core mixture is cured until substantially firm, such as by drying, heating or freezing. An outer layer may be formed adjacent the surface of the projectile core by heating. An outer coating may also be applied to the projectile core. A method of forming a projectile core comprises: (a) mixing a carrier and a colorant to form a core mixture; (b) forming the core mixture into a predetermined core shape; and, (c) curing the core mixture until a substantially firm projectile core is formed.
