Adjustable Pressure Regulator for Tranquilizer Dart Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tranquilizer dart delivery systems lack the fine control necessary for safely administering chemical immobilizers to human subjects, as they are designed for non-human animals and can cause unintended harm due to varying clothing thickness and force requirements.
Innovation Solution
A dart delivery apparatus with an adjustable pressure regulator system, including a gas conduit, trigger valve, and pressure display, allows for precise control of pneumatic force for dart ejection, featuring a frame with gaskets for secure dart placement and a shot volume modification apparatus to optimize gas pressure and volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-pressure pneumatic system is used for dart delivery, then the system structure is simple, but the force control is insufficient causing potential injury to human subjects
Solution Approach 1:
The patent applies dynamics by making the pressure regulator adjustable, allowing the operator to dynamically change the pneumatic pressure according to the subject's needs and clothing thickness. This transforms a static fixed-pressure system into a dynamic adjustable one, enabling fine control of dart ejection force to prevent injury while maintaining reasonable system complexity
Solution Approach 2:
The patent implements parameter changes by allowing the operator to adjust the pressure regulator to different pressure levels. This changes the physical parameter of gas pressure to adapt to different scenarios (different clothing thickness, different subjects), thereby achieving reliable and safe dart delivery without causing injury
2Adaptability or versatility
If higher gas pressure is used to ensure dart penetration through clothing, then the dart can penetrate various clothing types, but the risk of injuring the subject increases
Solution Approach 1:
The adjustable pressure regulator allows the operator to dynamically adjust the gas pressure based on the clothing thickness and type. For thin clothing like linen, lower pressure is used; for thick clothing like jeans or leather, higher pressure is applied. This dynamic adjustment ensures adaptability to different clothing while preventing injury from excessive pressure
Solution Approach 2:
The system changes the pressure parameter to match the required penetration force for different clothing types. By adjusting the pressure regulator, the operator can set the appropriate pressure level for each situation, achieving versatile penetration capability without causing harmful effects from consistently high pressure
