Wireless Power Receiver for Musical Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power solutions for musical instruments require close proximity to a transmitter, necessitating modifications that can alter the instrument's shape or sound quality, limiting their use and value.
Innovation Solution
A wireless power system that includes a resonator coupled to a musical instrument to capture electromagnetic energy and a rechargeable power supply, allowing for power transmission without physical modification, with a power conditioning circuit to control energy flow and a boost converter to adjust voltage, enabling charging over a longer distance without altering the instrument's shape or sound integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If inductive wireless charging is used to power musical instruments, then wireless power transmission is achieved, but the battery must be placed within very close proximity to the transmitter requiring physical modification of the instrument
Solution Approach 1:
The patent introduces a wireless power receiver as an intermediary device that couples to the musical instrument through existing connections (headphones jack, USB port, or power adapter) rather than requiring direct integration into the instrument. This intermediary approach enables wireless charging without modifying the instrument's body, as the receiver can be externally attached or connected through standard interfaces.
2Adaptability or versatility
If the instrument body is modified to accommodate wireless charging components, then wireless power capability is added, but the instrument's value and sound quality are compromised
Solution Approach 1:
The patent extracts the wireless charging functionality from the instrument body itself and places it in a separate, externally-coupled receiver unit. This extraction allows the instrument to gain wireless power capability without any physical modifications to its structure, preserving both its aesthetic value and sound quality while adding the desired adaptability.
3Reliability
If electrical cord is used to power the instrument, then continuous power supply is ensured, but musician movement is limited
Solution Approach 1:
The patent replaces the mechanical constraint of an electrical cord with a wireless electromagnetic field-based power transmission system. The wireless power receiver captures energy from electromagnetic fields in the environment, eliminating the need for physical cord connections and thereby freeing the musician's movement while maintaining reliable power supply to the instrument.

AI summary
A musical instrument requiring power has a wireless resonate power receiver to receive electric energy from electromagnetic waves transmitted by a wireless resonate power transmitter when the wireless resonate power receiver is within an area covered by the wireless resonate power transmitter. The electric energy can be stored in a rechargeable power supply, such that the musical instrument can be charged wirelessly.
