Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current toys lack interactive light sources that can effectively illuminate photo-luminescent ink and other inks, limiting their ability to enhance reading and interactive experiences.
Innovation Solution
A finger-worn toy with strategically positioned LED light sources, including black and colored lights, connected to a circuit board and power source, which can illuminate beyond the toy's tip to interact with photo-luminescent ink and other inks on books or surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional toys without integrated light sources are used, then the device complexity is low, but the illumination capability and interactive experience are insufficient
Solution Approach 1:
The patent combines multiple light sources (blacklight LED, white LED, colored LEDs) along with power source, circuit board, and control components into a single integrated toy device. This merging approach provides comprehensive illumination capabilities (UV for photo-luminescent ink, white light for general reading, colored lights for interactive effects) while managing device complexity through unified design.
Solution Approach 2:
The toy is designed with multi-functional light sources that serve different purposes: blacklight for revealing photo-luminescent ink, white light for general reading illumination, and colored LEDs for interactive experiences. This universal design allows a single device to perform multiple illumination functions, improving versatility without requiring separate devices for each function.
2Adaptability or versatility
If multiple LED light sources are integrated into the toy, then the interactive reading experience is enhanced, but the weight of the toy increases
Solution Approach 1:
The lighting system is segmented into distinct functional components (blacklight LED, white LED, colored LEDs) that can be independently controlled. This segmentation allows the toy to provide diverse interactive capabilities through different light types while managing weight by only activating necessary light sources during different play scenarios.
Solution Approach 2:
The toy utilizes different wavelengths and colors of light from multiple LED sources to create varied interactive experiences. By changing the parameter of light type (UV, white, colored) rather than adding more physical components, the toy achieves high adaptability and interactive capability while controlling overall weight.
3Ease of operation
If light sources are positioned to illuminate beyond the toy body, then the reading utility is improved, but the light sources may interfere with other toy functions
Solution Approach 1:
The light sources are positioned and oriented to project illumination in multiple directions and dimensions beyond the toy body. This spatial arrangement ensures that light reaches reading materials effectively while the strategic positioning allows different light sources to serve different functions without mutual interference, maintaining both reading utility and functional compatibility.
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 toy enhances reading experiences by providing interactive illumination, allowing children to use it as a pointer and light source for reading, revealing hidden writings, and creating an engaging interactive experience in low light environments.
Implementation Method 1
The toy includes at least one LED light source positioned on a body of the toy so the light source illuminates beyond the body of the toy
Implementation Method 2
The LED light sources include a black light and can include other LED lights of other colors. The light sources are positioned strategically anywhere on the toy

AI summary
A toy has one or more LED light sources positioned on the toy so the light source illuminates beyond the toy. A toy to be worn on the human finger comprises a body includes an anchoring portion for receiving or locating a finger or fingers. A LED or other light source is operated on the toy to interact with photo-luminescent ink and other inks pre-printed or included in a decoration on the surface of another item such as a book or other toy. The toy is a reading tool or a light source or an enhancement of other toys or writings. The LED light sources include a black light and/or other LED lights of other colors. The lights are connected to a circuit board and an integrated power source, which are connected to a switch encased on the toy.
