Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current toy guns lack simulation mechanisms and actions, particularly in trigger rotation and blowback, which are essential for realistic shooting experiences.
Innovation Solution
A gun design incorporating a trigger assembly, sear assembly, blowback assembly, and reciprocating slide with connecting members that allow the trigger to rotate and the sear assembly to move linearly, compressing a blowback spring to simulate the blowback action, thereby enhancing the simulation of real gun mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional trigger mechanisms are used in toy guns, then the structure is simple, but the simulation effect of real gun actions is poor
Solution Approach 1:
The trigger mechanism is divided into separate functional components: a trigger assembly that rotates, a sear assembly with movable and fixed sears, and a blowback assembly. This segmentation allows each component to perform its specific function independently, achieving realistic gun simulation while keeping the overall structure manageable through modular design.
Solution Approach 2:
The trigger assembly is designed to rotate dynamically rather than slide horizontally, mimicking the action of real gun triggers. The sear assembly includes movable and fixed sears that interact dynamically during the shooting cycle, and the blowback assembly moves reciprocally to simulate recoil, enhancing the simulation effect through dynamic motion.
2Reliability
If blowback mechanism is added to simulate real gun recoil, then the simulation effect improves, but the device complexity increases
Solution Approach 1:
The blowback assembly is integrated with the existing trigger and sear mechanisms. The blowback piston connects to the trigger assembly through the blowback rod, and the blowback spring is positioned within the receiver assembly. This merging allows the blowback function to be achieved without adding completely separate mechanisms, reducing overall complexity while maintaining simulation effectiveness.
Solution Approach 2:
The receiver assembly serves multiple functions: it houses the trigger assembly, sear assembly, and blowback assembly, and provides structural support for all components. The magazine assembly also serves dual purposes by holding ammunition and providing structural support. This multi-functionality reduces the need for additional dedicated components, thereby reducing complexity.
3Reliability
If multiple connecting members are used to link trigger, sear assembly and blowback assembly, then the simulation of real gun mechanisms improves, but the device complexity increases
Solution Approach 1:
The first and second connecting members serve as intermediaries that transmit force and motion between the trigger assembly, sear assembly, and blowback assembly. The first connecting member links the trigger to the movable sear, while the second connecting member links the trigger to the blowback rod. These intermediary components enable realistic mechanism simulation through controlled force transmission while maintaining clear functional relationships between components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a realistic simulation of trigger rotation and blowback actions, providing a more immersive shooting experience by mimicking the mechanisms and actions of real guns.
Implementation Method 1
One end of the blowback spring close to the magazine abuts against the energy-storing slide. The energy-storing slide and the blowback spring are accommodated in the blowback slide. The energy-storing slide compresses the blowback spring, and the blowback slide receive a restoring energy of the blowback spring to drive the reciprocating slide to move in the first direction.

AI summary
A gun includes a receiver assembly, a magazine, a trigger assembly, a sear assembly, a blowback assembly and a reciprocating slide. When the trigger rotates, the first connecting member is capable of pulling the trigger slide to move linearly, and driving the second connecting member, the sear assembly and the force-storing slide to move linearly towards the same direction. Moreover, the force-storing slide compresses the blowback spring, and the blowback slide receives a restoring force of the blowback spring to drive the reciprocating slide to move backward. The gun could achieve a simulation effect of rotating actions of the trigger, as well as a simulation effect of blowback actions of the reciprocating slide.
