Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional specialty items, such as lighted decorations, often rely on cumbersome wires or batteries, which can be aesthetically unpleasing and pose fire hazards, with battery replacement becoming increasingly tedious as the number of items grows.
Innovation Solution
A wireless RF power system comprising a transmitter and receiver, where the receiver converts wireless power into usable power to activate components like lights, sounds, or scents, eliminating the need for physical wires or frequent battery replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard wired power is used for specialty items, then power supply is reliable, but wires are cumbersome and unaesthetic and pose fire hazards
Solution Approach 1:
The patent replaces the mechanical wire-based power transmission system with an electromagnetic field-based wireless power transmission system. The transmitter generates electromagnetic fields that couple with receiver coils in the specialty items, transferring power without physical connections. This eliminates the fire hazards and aesthetic issues associated with exposed wires while maintaining reliable power supply.
2Ease of operation
If batteries are used for power, then no wires are needed, but batteries must eventually be replaced and maintenance becomes tedious
Solution Approach 1:
The system enables self-charging of specialty items through wireless power transmission. The transmitter continuously or periodically transmits power wirelessly to the items, which receive and store it in their internal batteries or capacitors. This eliminates the need for manual battery replacement while maintaining wireless operation, as the items automatically recharge themselves from the environmental power source.
3Reliability
If multiple battery-powered items are used, then wireless operation is achieved, but battery replacement becomes increasingly tedious
Solution Approach 1:
The transmitter serves multiple specialty items simultaneously through a single wireless power source. The electromagnetic field generated by the transmitter can power multiple receivers within its coverage area, eliminating the need for separate battery management for each item. This reduces maintenance complexity from managing multiple individual batteries to managing a single centralized power source, while maintaining continuous wireless operation of all items.
