Airsoft Gun Compressed Air Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-soft guns retain compressed air in the pistol-grip space after firing, requiring significant force for subsequent shots and increasing the risk of injury due to increased pressure.
Innovation Solution
An air-soft gun with a remaining compressed air release device featuring a cylindrical channel member, a rotatable cap, a sealing ring, and a compression spring, which allows for the controlled release of compressed air from the pistol-grip to the external environment through a needle that also pierces the air canister for pressurized air release before firing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed air is retained in the pistol-grip space after firing, then the air-soft gun maintains pressure for subsequent shots, but a great force is required to exert in the next firing and the probability of being hurt increases
Solution Approach 1:
The patent extracts the excess compressed air from the pistol-grip space through a release valve mechanism. The valve allows selective discharge of remaining compressed air after firing, removing the harmful pressure buildup while maintaining sufficient pressure for subsequent shots. This resolves the contradiction by taking out only the excess air that causes difficulty in operation.
Solution Approach 2:
The patent changes the pressure parameter in the pistol-grip space by introducing a release mechanism that adjusts the compressed air pressure from a high state (after firing) to a lower state (before next firing). This parameter change allows the system to transition between pressure maintenance and ease of operation states.
2Reliability
If compressed air is retained in the pistol-grip space after firing, then the air-soft gun maintains pressure for subsequent shots, but the probability of being hurt increases
Solution Approach 1:
The release valve mechanism extracts and discharges excess compressed air that would otherwise build up to dangerous levels in the pistol-grip space. By removing this excess air, the system eliminates the harmful high-pressure condition that could cause injury, while preserving enough pressure for reliable subsequent shots.
Solution Approach 2:
The patent converts the potentially harmful excess compressed air into a beneficial controlled release mechanism. The release valve transforms the dangerous pressure buildup into a controlled discharge process that safely eliminates excess air while maintaining operational pressure, turning a harmful factor into a safety feature.
3Ease of operation
If a release device is added to the air-soft gun, then remaining compressed air can be released easily, but the device complexity increases
Solution Approach 1:
The release valve mechanism is designed to be self-operating through a simple triggering mechanism. When activated, the valve automatically releases the compressed air without requiring complex control systems or multiple components. The spring-loaded design provides self-service functionality that simplifies operation while minimizing device complexity.
Solution Approach 2:
The patent applies a localized release mechanism only at the specific location where compressed air needs to be discharged (the pistol-grip space). Rather than redesigning the entire air supply system, the solution focuses on a local quality change by adding a simple valve at the critical point, thereby improving ease of operation with minimal increase in overall device complexity.

Function Achieved in This Case
Facilitates easier and safer subsequent firing operations by reducing the force required and minimizing the risk of injury by effectively releasing remaining compressed air and ensuring consistent pressurized air supply for the next shot.
Implementation Method 1
a compression spring fastened between the cap and the cylindrical channel member and urging against the cylindrical channel member
Implementation Method 2
a sealing ring; wherein the inlet is blocked by the sealing ring in an inoperative position of the remaining compressed air release device
