Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of using a screw base to push a compressed gas cylinder into a toy gun is time-consuming, labor-intensive, and inconvenient, requiring balancing of internal and external pressures for detachment.
Innovation Solution
A gas cylinder piercing structure that includes a screw base with an air vent channel, formed by engaging an engagement lug with a slot, allowing gas pressure to be relieved and facilitating quick disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw base is used to push the compressed gas cylinder into the gas cylinder barrel, then the gas cylinder can be securely positioned, but the operation becomes time-consuming and labor-intensive requiring multiple rotations
Solution Approach 1:
The piercing structure is divided into separate components: a piercing member with piercing portion and engagement lug, and a screw base with slot. The piercing member can be independently inserted through the gas cylinder mouth and then engaged with the screw base, allowing the gas cylinder to be secured without requiring multiple rotations of a single complex component.
Solution Approach 2:
The piercing member acts as an intermediary component between the screw base and the gas cylinder. It first pierces the gas cylinder mouth to secure it, then engages with the screw base to lock the position, eliminating the need for multiple rotational operations.
2Reliability
If the screw base is turned multiple times to push the compressed gas cylinder, then the gas cylinder can be positioned, but the detachment requires pressure balancing which is inconvenient
Solution Approach 1:
The detachment process is simplified by separating the piercing member from the screw base. The piercing member can be easily removed from the gas cylinder mouth without requiring pressure balancing, and then the screw base can be detached from the piercing member structure, making the overall detachment operation convenient.
Solution Approach 2:
The piercing member serves as an intermediary that facilitates both insertion and detachment. During insertion, it pierces the gas cylinder and engages with the screw base. During detachment, it can be easily removed from the gas cylinder mouth first, then the screw base is detached, eliminating the need for pressure balancing.
3Stress or pressure
If the piercing structure uses a sealed design to maintain pressure, then gas pressure is maintained, but disassembly becomes difficult due to pressure imbalance
Solution Approach 1:
The piercing member acts as an intermediary component that can be independently removed from the gas cylinder mouth. This allows the gas pressure to be maintained in the sealed gas cylinder barrel while enabling easy disassembly of the piercing structure without requiring pressure balancing.
Solution Approach 2:
The piercing structure is segmented into the piercing member and screw base, allowing the piercing member to be removed independently to relieve pressure or facilitate disassembly, while the gas cylinder remains sealed and pressurized.
4Reliability
If the piercing structure is designed for secure engagement, then reliable connection is achieved, but the structure becomes complex requiring multiple components
Solution Approach 1:
The piercing structure is segmented into a piercing member with piercing portion and engagement lug, and a screw base with slot. This segmentation allows for simple, reliable engagement without complex mechanisms - the engagement lug fits into the slot to secure the connection.
Solution Approach 2:
The piercing member serves as a simple intermediary component that provides reliable engagement through its engagement lug fitting into the slot of the screw base, avoiding the need for complex locking mechanisms.

AI summary
A toy gun and a gas cylinder piercing structure are provided. The gas cylinder piercing structure includes a screw base and a movable push rod unit. The screw base includes a circular through-hole and an annular block around it. A top of the annular block has a slot. The movable push rod unit includes a round push rod movably inserted in the circular through-hole, and a return spring between the screw base and the round push round. A top of the round push rod has a striker pin. The striker pin extends with a needle portion. The striker pin has an engagement lug and a notch. When the engagement lug is blocked by the annular block, the round push rod completely fills the circular through-hole. When the engagement lug is engaged with the slot, the notch and the circular through-hole together form an air vent channel.
