Compressed Air Gun Loading Lever Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional direct spray type compressed air guns require significant power to load the hammer due to the need for a heavy hammer and strong compression spring, making it difficult for users to load the gun efficiently, especially given the limited space for the loading mechanism.
Innovation Solution
A direct spray type compressed air gun design that utilizes a loading lever to move the hammer to a loading position with minimal power, incorporating a spring to press the hammer towards the valve, a latch to block its movement, and a trigger to release it, allowing the hammer to strike the valve collar and propel the projectile with high-speed compressed air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a heavy hammer and strong compression spring are used to apply strong impact to the valve for high-pressure air discharge, then the valve can discharge high-pressure air effectively, but the loading action requires great power to move the heavy hammer against the spring
Solution Approach 1:
The hammer mechanism is divided into two parts: a heavy hammer head for delivering strong impact to the valve, and a lightweight hammer body that is moved by the loading lever. This segmentation allows the impact force to be strong while the loading power requirement remains low, as only the lightweight body needs to be moved during loading.
Solution Approach 2:
A loading lever is introduced as an intermediary mechanism between the user's loading action and the hammer. The loading lever provides mechanical advantage, allowing a small power input to move the hammer body against the compression spring while the heavy hammer head delivers the required strong impact to the valve.
2Force
If a heavy hammer is used to apply strong impact to the valve, then high-pressure air can be discharged, but the loading means must be mounted in a very small size on the air gun side
Solution Approach 1:
The hammer is segmented into a heavy hammer head and a lightweight hammer body. The loading mechanism only needs to move the lightweight body, which significantly reduces the size and power requirements of the loading means, allowing it to be mounted in the limited space on the air gun side.
Solution Approach 2:
The loading lever acts as an intermediary that amplifies the user's small input force and movement. This mechanical advantage allows the loading mechanism to be compact while still achieving the necessary hammer movement for high-pressure air discharge.
3Speed
If a heavy hammer and strong compression spring are used, then the valve can be struck with strong impact for high-speed projectile propulsion, but the overall device complexity increases
Solution Approach 1:
The hammer system is segmented into functional components with distinct roles: the heavy hammer head for impact delivery and the lightweight hammer body for movement. This segmentation simplifies the loading mechanism while maintaining the strong impact capability needed for high-speed projectile propulsion.
Solution Approach 2:
The loading lever serves as a mediating mechanism that simplifies the overall system by providing mechanical advantage. It reduces the complexity of the loading action while enabling the heavy hammer and strong spring combination to achieve the required projectile speed.

Implementation Method 1
a spring which is mounted between the hammer part and the barrel holder to press the hammer part in the direction of the valve part
Implementation Method 2
when the hammer part moved to the loading position directly strikes a valve collar
Implementation Method 3
highly-compressed air of a fixed quantity is sprayed in the direction of a projectile and the projectile is propelled at high speed
