Solution Overview

Problem

Conventional toy gun magazines require manual operation for replacement, leading to slower replacement speeds and unnecessary movement of the gun body, which is inefficient, especially during rapid-fire scenarios.

Innovation Solution

An active magazine disengagement structure featuring a magazine body with a trigger device, interlocking device, and on-off device that allows the magazine to separate from the gun body automatically once all bullets are fired, utilizing a combination of elastic elements and interlocking mechanisms to release the magazine under gravity, eliminating the need for manual operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If manual operation is used to replace the magazine, then the structure is simple, but the replacement speed is slow and the gun body moves

Engineering Contradiction:
Improvemagazine replacement speedVSAvoiddisengagement structure complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The magazine disengagement structure uses the trigger device's natural movement after bullet exhaustion to automatically drive the interlocking device and on-off device, enabling the magazine to self-disengage without manual intervention. The system leverages the existing mechanical energy from the trigger's movement to activate the disengagement sequence, making the magazine replacement process self-service and eliminating the need for external manual operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The interlocking device is pre-positioned to engage with both the magazine body and gun body before firing occurs. The on-off device is pre-configured to respond to the trigger's movement. This preliminary arrangement ensures that when the trigger moves after bullet exhaustion, the disengagement action is already prepared and can execute immediately, achieving rapid magazine replacement without requiring subsequent manual intervention.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If manual operation is used to replace the magazine, then the structure is simple, but the gun body moves during replacement

Engineering Contradiction:
Improvegun body stabilityVSAvoidmagazine replacement operation
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The disengagement structure performs the magazine replacement function automatically through the interaction between the trigger device, interlocking device, and on-off device. The system uses the trigger's natural movement to drive the entire disengagement sequence, eliminating the need for users to manually manipulate the magazine or gun body. This self-service mechanism ensures the gun body remains stable and stationary during the replacement process.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The disengagement function is segmented into distinct components: the trigger device that detects bullet exhaustion, the interlocking device that secures the magazine, and the on-off device that releases the retention. This segmentation allows each component to perform its specific function independently, with the trigger's movement sequentially activating the interlocking and on-off devices, thereby achieving stable, controlled magazine replacement without moving the gun body.

Inventive Principle:
Principle #1Segmentation

3Productivity

If automatic disengagement is implemented, then replacement speed improves, but the device complexity increases

Engineering Contradiction:
Improvemagazine replacement efficiencyVSAvoiddisengagement structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The trigger device serves dual functions: it operates during normal firing to advance bullets and, after bullet exhaustion, automatically drives the interlocking device to initiate magazine disengagement. The on-off device also performs multiple roles by responding to the trigger's movement to release the magazine retention. This multi-functionality reduces the need for separate dedicated components, thereby improving replacement efficiency while limiting the increase in overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The disengagement function is merged with the existing trigger mechanism rather than being implemented as a separate independent system. The trigger's natural movement after bullet exhaustion is combined with the interlocking device activation, and the on-off device is integrated to respond to the same trigger movement. This merging approach allows automatic disengagement to be achieved by utilizing and extending existing components, thereby improving productivity while minimizing the addition of new complex elements.

Inventive Principle:
Principle #5Merging (Combining)
