Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toys, particularly reusable water bomb alternatives, fail to replicate the explosive burst effect of single-use water balloons and often pose environmental litter issues or safety concerns due to hard plastic components.
Innovation Solution
A reusable toy capsule apparatus with a two-part refillable water balloon feature that bursts upon impact, utilizing soft materials and a partial vacuum mechanism to trap water, allowing for a splash effect similar to a balloon burst.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single-use water balloons are used, then the explosive burst effect is achieved, but substantial quantities of litter are created
Solution Approach 1:
The patent replaces disposable single-use water balloons with reusable soft toy capsules. The capsule is designed to be filled, thrown, and reused multiple times while maintaining the burst effect, thereby eliminating litter creation while preserving the desired explosive splash effect.
Solution Approach 2:
The capsule components are designed to separate upon impact, allowing the water to be released while the capsule halves can be recovered, collected, and refilled for reuse. This recovers the reusable components while discarding only the water, eliminating litter accumulation.
2Loss of substance
If reusable splash toys are used, then litter is reduced, but they fail to explode like balloons
Solution Approach 1:
The capsule is designed with specific physical parameters including soft material composition, wall thickness, and internal pressure that enable it to explode upon impact. The material hardness and structural integrity are carefully balanced to allow the capsule to contain water during normal use but disintegrate on impact to create the desired burst effect.
Solution Approach 2:
The capsule is designed with a spherical shape that concentrates impact force uniformly across the surface, enabling predictable and consistent bursting behavior. The curved geometry helps distribute stress during impact while maintaining structural integrity during normal handling and throwing.
3Strength
If hard plastic components are used for capsule mechanics, then structural strength is improved, but safety is compromised due to impact injury risk
Solution Approach 1:
The capsule is constructed from soft, flexible materials rather than hard plastic. The soft material provides sufficient structural strength to contain water during normal use while being safe for children during play. The flexibility allows the capsule to deform and disintegrate safely on impact without causing injury.
Solution Approach 2:
The capsule uses composite material construction combining soft outer material with internal structural elements. This provides the necessary structural strength to maintain shape and contain water while the soft exterior ensures safety during impact with children's bodies.
4Ease of operation
If mechanical valves are used to release water on impact, then water release mechanism is achieved, but splash size is limited and desirability is reduced
Solution Approach 1:
The capsule is divided into two separable halves that naturally separate upon impact. This segmentation eliminates the need for mechanical valves while enabling complete water release. The simple separation mechanism allows the entire water load to be discharged, creating a large, desirable splash effect.
Solution Approach 2:
The complex mechanical valve system is extracted and replaced with a simple separation mechanism. The capsule halves separate upon impact, naturally releasing all water without requiring any active valve operation, thereby maximizing splash size while simplifying the mechanism.

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 apparatus provides an exciting and environmentally friendly water toy that replicates the burst effect of single-use balloons without litter, using soft materials that dissipate kinetic energy in a splash, ensuring safety and reusability.
Implementation Method 1
The fluid seal creates a partial vacuum sufficient for a lower relative internal pressure inside to create a suction force that moves water into the capsule
Implementation Method 2
Hydrostatic pressure of the water pushing against the walls to generate surface tension
Implementation Method 3
Hydrostatic pressure of the water pushing against the walls to generate surface tension

AI summary
An amusement device in the general form of a reusable water capsule that explodes with the affect of toys commonly referred to as water-balloons and the like. User may choice between a reusable exploding water capsule to be thrown at a target and a device for shooting a directional stream of water similar to a "squirt gun". A variety of various shaped flexible components each of which including a first wall with a first wall external surface and a first wall internal surface, and a second wall with a second wall external surface and a second wall internal surface for interconnection. This toy may be used as packaging, within the capsule, for additional items. The combination of unique design with the typically chosen softness of the material used to make the capsule means much of the kinetic energy in a throw is dissipated in a water burst.
