Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulation guns face challenges in minimizing the retracting amount of the nozzle and extending the open time of the bullet supply port, particularly when dealing with multiple barrels, which affects the efficient loading and firing of bullets.
Innovation Solution
A bullet supply port opening-closing device with a communication member that divides the movable and nozzle parts, allowing for adjustable open time by engaging and disengaging these parts via an engagement mechanism, minimizing the nozzle's retracting amount and maintaining the open state for a required time to facilitate efficient bullet loading across multiple barrels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the nozzle retracting time is extended to lengthen the open time of the bullet supply port, then the open time is increased, but the nozzle size increases and causes space loss and compression efficiency loss
Solution Approach 1:
The communication member is divided into a first communication member connected to the movable portion and a second communication member connected to the nozzle. These segmented members can move independently, allowing the nozzle to maintain a short retracting distance while the first communication member extends further to achieve the required open time for bullet supply.
2Duration of action of moving object
If the nozzle is integrated with the tappet member to lengthen the open time, then the open time is increased, but the moving distance of the nozzle increases causing space loss and compression loss
Solution Approach 1:
The communication member is segmented into two independent parts: the first communication member (tappet side) and the second communication member (nozzle side). This segmentation allows the nozzle to remain short and fixed in position, minimizing compression loss, while the first communication member provides the necessary movement duration to extend the open time.
Solution Approach 2:
The first communication member acts as an intermediary between the movable portion and the second communication member. It transmits the movement from the movable portion to the second communication member, enabling the nozzle to remain short while still achieving the required open time through the intermediary's movement.

AI summary
[Problem] A retracting amount of a nozzle is minimized, and an open time for a bullet supply port is maximally shortened. [Solution] Provided is a bullet supply port opening-closing device in a simulation gun which generates compressed air by operating a piston cylinder mechanism, blasts a bullet loaded in a barrel with the compressed air from a nozzle, and shoots the bullet. The bullet supply port opening-closing device includes a communication member 63 that causes the nozzle to retract in response to an operation of a movable portion of the piston cylinder mechanism and transmits the operation of the movable portion to the nozzle in order to open a bullet supply port 62 leading to a space in front of the nozzle. The communication member is constituted by a plurality of divided parts on the movable portion side and the nozzle side. A nozzle side part and a movable portion side part are configured to be able to be engaged with and disengaged from each other by an engagement mechanism 65 such that the nozzle side part and the movable portion side part integrally retract so as to open the bullet supply port, after the nozzle side part is isolated from the movable portion side part which continues to retract, an open state is retained for a certain time, and the movable portion side part advances so as to be integrated with the nozzle side part.
