Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small, portable toys with lights and sounds often get lost due to their size, leading to frequent replacements.
Innovation Solution
A motion-activated, wearable illuminated bracelet with centrifugal force-activated charms, including lights and sounds, designed to be worn on the wrist, featuring a circular main body with resilient tethers that expand and contract with spinning, providing entertainment and reducing loss risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the toy is made small and portable, then it is easier to take anywhere, but it is more likely to be lost
Solution Approach 1:
The patent transitions the toy from a handheld portable form to a wrist-worn form factor. By moving the toy to another dimension (wristwear), it maintains portability while significantly reducing loss risk through increased visibility and awareness. The bracelet design allows the toy to be worn on the wrist, making it both portable and less likely to be lost.
2Adaptability or versatility
If the toy has lights and sounds, then it is more entertaining, but it requires more power and complexity
Solution Approach 1:
The patent implements dynamic activation where lights and sounds are triggered by centrifugal force generated during spinning. The system transitions from static to dynamic operation, where features activate only when needed (during play). This reduces power consumption and simplifies control logic compared to continuously operating systems.
Solution Approach 2:
The toy uses the user's own spinning action to activate its features. The centrifugal force generated by the user's hand spinning the bracelet automatically triggers the lights and sounds without requiring additional buttons, switches, or complex control mechanisms. This self-activating mechanism reduces overall system complexity.
3Reliability
If the bracelet is worn on the wrist, then it is less likely to be lost, but it requires space on the wrist
Solution Approach 1:
The patent divides the bracelet into modular components including a main body and detachable charms. This segmentation allows the bracelet to be compact when not in use while providing sufficient surface area for features when worn. The modular design enables the bracelet to adapt to different wrist sizes and conditions.
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 bracelet offers hours of entertainment for children of all ages, reducing the likelihood of loss and serving as a fashion accessory while being worn, with charms activated by spinning, providing a unique and engaging experience.
Implementation Method 1
Each of the illuminating charms can include a power source, a switch and a light, and can be activated by the centrifugal force of the bracelet spinning about the finger of a user
Data Source
AI summary
A motion activated illuminated bracelet includes a circular shaped main body having an inside diameter that is suitable for being worn about the wrist of a user. A plurality of illuminating charms is positioned equidistantly along the main body and include a power source, a switch and a light. A plurality of audible charms is positioned equidistantly along the main body and include a power source, a switch and a speaker. A plurality of decorative charms is positioned equidistantly along the main body and include a housing having any number of decorative elements, and a weight that is complementary to the weight of an audible charm or an illuminating charm. Each of the illuminating charms and the audible charms are selectively activated by a centrifugal force associated with the rotation of the bracelet, and some of the illuminated charms are connected to the main body via a resilient tether.
