Solution Overview
Problem
Portable electronic devices are limited in portability and usage range during charging due to the need for a plug connection, which restricts their use while being recharged.
Innovation Solution
A portable charger tray with an internal rechargeable power supply and a wireless power transmitter allows for wireless charging of devices, accompanied by a dock for recharging the tray's power supply, enabling charging without tethering and extending usage locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plug connection is used for recharging, then the device can be recharged reliably, but the portability and range of locations are limited
Solution Approach 1:
The patent extracts the charging connection from a fixed plug-in configuration to a portable wireless configuration. The charging dock separates the power source from the device, allowing the device to be charged without being tethered to a wall outlet, thereby extracting the limiting constraint (physical plug connection) while maintaining reliable charging through the dock's power supply.
Solution Approach 2:
The charging dock serves as an intermediary between the power source and the portable device. It provides wireless power transmission to the device while remaining connected to power, acting as a mediator that enables reliable charging without requiring a direct plug connection to the device, thus expanding usage location range.
2Use of energy by moving object
If a tether is used for charging, then power can be supplied continuously, but the range of locations is restricted
Solution Approach 1:
The patent replaces the mechanical tether connection with a wireless power transmission system. The charging dock uses wireless technology (such as electromagnetic induction or resonance) to transmit power to the device without physical contact, eliminating the mechanical constraint of the tether length while maintaining continuous power supply capability.
3Adaptability or versatility
If wireless charging is implemented, then portability is maintained, but power transmission efficiency may be reduced
Solution Approach 1:
The charging dock is designed to optimize wireless power transmission efficiency through self-adjusting mechanisms. It likely includes features such as automatic power level adjustment, positioning guidance, or interference detection that allow the system to self-optimize the power transmission process, minimizing energy loss while maintaining portability and wireless operation.
