Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional squirting toys face limitations in generating electricity while in use, as they rely on batteries that lose power and require wiring prone to moisture-related failures, and existing water-driven generators are restricted by hose range.
Innovation Solution
A squirting toy design incorporating a housing with a variable volume chamber, a piston, and an electrical generating assembly that includes a turbine and dynamo, powered by user-driven water flow, allowing for electricity generation without batteries, with a soft non-water-absorbing shell for buoyancy and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If batteries are used to power illumination or sound making devices, then the toy can operate without external power sources, but the batteries lose power over time and require replacement
Solution Approach 1:
The system uses the water flow itself to generate electricity through the water-driven generator module, eliminating the need for separate batteries. The kinetic energy of the flowing water directly powers the electrical devices, making the system self-sufficient and continuously operable as long as water flows.
Solution Approach 2:
The patent replaces the chemical energy storage system (batteries) with a mechanical energy conversion system (water-driven generator). The mechanical motion of water flowing through the generator module converts directly to electrical energy, providing continuous power without depletion.
2Adaptability or versatility
If wiring and electronics are added to power illumination or sound making, then the toy can produce electrical functions, but the wiring can fail when exposed to moisture
Solution Approach 1:
The electrical generating assembly is integrated directly into the water flow path, combining the mechanical water-driven generator with the electrical output in a single unified component. This eliminates separate wiring connections and protects electronics from moisture exposure while maintaining electrical functionality.
3Use of energy by moving object
If a water driven generator module is used to generate electricity, then batteries are eliminated, but the toy is restricted for use by the range of the hose
Solution Approach 1:
The water-driven generator module is designed to function with any water flow source, making the toy adaptable to both hose-connected and standalone water supply configurations. The same generator can utilize water from a hose or from a pool, eliminating the limitation to hose range while maintaining electricity generation capability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous operation without battery replacement, reduces electronic failure risks, and provides enhanced range and safety through buoyancy and soft shell protection, while generating electricity from user-driven water flow.
Implementation Method 1
a dynamo system adapted to convert the mechanical energy of the water flow to electrical energy
Implementation Method 2
an electrical generating assembly that can power an electric device, wherein electricity can be generated by slidably moving the piston longitudinally within the chamber causing the water to power the electrical generating assembly
Implementation Method 3
a soft non-water-absorbing shell disposed over a portion of the external surface of the housing
Data Source
AI summary
A squirting toy capable of squirting water received from a reservoir and/or from an external source. The squirting toy can include a housing, a piston, a shaft, and an handle portion. As the piston is slidably moved through the housing the water can be squirted out of the housing. Further, as the piston is slidably moved through the housing an electrical assembly including a turbine can be activated generating electricity to power an electric device (e.g., a light).
