Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toy water balloons, both magnetic and non-magnetic, face issues such as magnetic parts posing a swallowing hazard and high cost, or poor sealing and stability leading to water overflow and poor user experience.
Innovation Solution
A toy water balloon design featuring a flexible shell, a flexible cover with an elastic arm that applies outward force to seal the water storage cavity, eliminating the need for magnetic parts and enhancing sealing properties through the use of an elastic arm and optional elastic ring to maintain a tight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic parts are used in toy water balloons to prevent shell separation, then the shells can be enclosed to limit a water storage cavity and avoid being easily separated, but the cost increases due to multiple magnetic parts and there is a safety risk if magnetic parts fall out and are swallowed by children
Solution Approach 1:
The patent removes magnetic parts from the toy water balloon structure entirely, extracting the harmful element while maintaining the functional requirement of shell connection through alternative means (suction force and structural design)
Solution Approach 2:
The patent replaces the magnetic field-based connection system with a mechanical suction-based connection system, where the flexible shell creates negative pressure to hold the cover in place, eliminating the need for magnetic components
2Ease of manufacture
If non-magnetic toy water balloons use two half spheres fastened at edges to define a water storage cavity, then the production cost is reduced, but the tightness is poor causing water overflow and the connection stability is poor causing separation before hitting the player
Solution Approach 1:
The patent uses a flexible shell that can deform to create a tight seal with the cover through suction force, leveraging the elastic properties of the flexible material to maintain connection without complex fastening mechanisms
Solution Approach 2:
The patent designs the cover and opening structure to prevent water overflow before it occurs by creating a sealed configuration that resists water escape, with the suction force pre-established to maintain this密封 state
3Ease of manufacture
If non-magnetic toy water balloons use two half spheres fastened at edges, then the production cost is reduced, but the connection stability is poor causing the halves to be easily separated
Solution Approach 1:
The patent replaces weak mechanical fastening at edges with a suction-based mechanical system where the flexible shell creates negative pressure to hold the cover firmly in place, providing stronger connection stability
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 ensures high safety with no magnetic parts, reduces production costs, and provides excellent sealing to prevent water overflow, enhancing user experience and interactivity.
Implementation Method 1
an elastic arm; the elastic arm is connected to the flexible shell, the elastic arm is configured to apply an exert force on the flexible cover to ensure it seals the water storage cavity

AI summary
The present disclosure relates to the technical field of water playing toys, particularly to a toy water balloon, which comprises a flexible shell, a flexible cover and an elastic arm. The flexible shell limits a water storage cavity and an opening connects the water storage cavity and the external space of the flexible shell. The outer contour of the flexible cover is larger than that of the opening to seal the water storage cavity. It is only needed to make the toy water balloon deformation by using the opening to expose the water storage cavity. Which results in higher safety and lower production cost. Compared with the non-magnetic toy water balloon, the flexible cover will stick closely to the inner wall of the water storage cavity so that the toy water balloon disclosed in the present application has good sealing properties.
