Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional paintball markers are limited by air resistance, gravity, and mechanical triggers, restricting the practical rate of fire to around 10 bps, and require large gas canisters that reduce mobility and convenience.
Innovation Solution
A fuel-powered paintball marker with a combustion chamber, separate fuel and oxidizing agent systems, and a solenoid-controlled valve system that ignites the mixture to drive a piston for higher firing rates, using a two-stage process to separate and combine fuel and oxidizing agent for efficient combustion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional compressed gas systems are used, then the paintball marker can achieve reliable propulsion, but the rate of fire is limited to around 10 bps due to mechanical trigger constraints
Solution Approach 1:
The patent replaces the traditional mechanical trigger and sear system with an electronic control system that uses solenoid valves to control gas flow. This substitution eliminates the mechanical limitations that capped the rate of fire at 10 bps, allowing the system to achieve over 20 bps by using electronic signals to rapidly actuate the valves without the inertia and friction constraints of mechanical components.
2Duration of action of moving object
If large gas canisters are used to extend shooting duration, then the number of shots per tank increases, but mobility and convenience are reduced
Solution Approach 1:
The patent segments the gas storage system into multiple smaller tanks rather than using one large canister. This segmentation allows the system to achieve the same total gas capacity (extending shooting duration) while improving mobility, as multiple smaller tanks are easier to carry and distribute weight more evenly across the player's body.
Solution Approach 2:
The patent changes the physical parameters of the gas storage system by using multiple smaller tanks with reduced individual volumes. This parameter change maintains the total gas capacity needed for extended shooting duration while improving the ease of operation and mobility by reducing the size and weight of each individual tank.
3Reliability
If fuel and oxidizing agent are stored separately in first stage, then safety is increased, but the system requires a two-stage mixing process
Solution Approach 1:
The patent implements preliminary action by pre-storing fuel and oxidizing agent in separate chambers (first stage) before combustion is needed. This preliminary separation maintains safety by preventing accidental combustion during storage and transport. The system then rapidly mixes these pre-positioned components in the second stage when combustion is required, achieving both safety and operational efficiency.
