Electric Piston Water Spray Structure for Continuous Toy Water Gun Shooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional toy water guns require manual squeezing to release water streams, leading to a slow shooting rate and finger discomfort due to prolonged use.
Innovation Solution
A water spray structure with an electric motor-driven piston mechanism, utilizing a combination of gears and a swinging mechanism for continuous water stream discharge, eliminating the need for manual squeezing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual squeezing is used to release water streams, then the structure is simple, but the shooting rate is slow and causes finger discomfort
Solution Approach 1:
The patent replaces the manual mechanical squeezing system with an electric motor-driven piston system. The motor (4) drives the piston (3) through a transmission mechanism (gears and swing rod) to achieve automated water ejection, eliminating the need for manual finger squeezing and enabling continuous high-rate shooting.
2Productivity
If an electric motor-driven piston mechanism is used, then the shooting rate increases and finger discomfort is eliminated, but the device complexity increases
Solution Approach 1:
The transmission mechanism is divided into separate functional modules: a gear assembly (motor gear, driving gear, transition gear) for motion conversion and a swing rod mechanism for reciprocating motion. This segmentation allows each component to be optimized independently and simplifies maintenance.
Solution Approach 2:
The swing rod mechanism serves multiple functions: it converts rotational motion from the gears into reciprocating linear motion of the piston, and also acts as a structural support element connecting the driving mechanism to the piston assembly.
3Productivity
If manual squeezing releases one water stream per squeeze, then the structure is simple, but the shooting rate is slow
Solution Approach 1:
The electric motor provides continuous rotational motion, and through the swing rod mechanism, this is converted into continuous reciprocating motion of the piston. The piston continuously alternates between drawing water into the spray chamber and ejecting water through the nozzle, achieving uninterrupted water stream discharge.
