Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charging methods for cellular phones and portable electronic devices require bulky adapters and cables, limiting their use in a mobile fashion during recharging.
Innovation Solution
A compact, wireless charging device with a first housing and adapter that includes status LEDs for charge indication, allowing for easy insertion and simultaneous charging of multiple devices without cables, using a circular input port and various output formats like USB-mini, USB-C, or Apple Lightning, and capable of fast charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wall or automobile adaptors are used for charging, then charging function is provided, but the device becomes bulky and ties the user to a cable and charging source
Solution Approach 1:
The charging system is divided into two independent components: a compact charging device with battery that can be held in the hand, and a separate adapter unit. This segmentation eliminates the need for a physical cable connection between the two, enabling mobile usage while charging.
Solution Approach 2:
The patent introduces a wireless communication intermediary (such as infrared or radio frequency communication) to establish the connection between the charging device and the adapter unit. This intermediary replaces the physical cable, allowing the user to move freely while maintaining the charging connection.
2Adaptability or versatility
If a compact wireless charging device is used, then mobile usage during charging is enabled, but multiple charging devices cannot be charged simultaneously without an adapter
Solution Approach 1:
The adapter unit is designed with multiple charging ports (e.g., three USB ports) that can simultaneously charge multiple charging devices. This multi-functional design allows a single adapter to serve multiple devices at once, increasing the system's versatility without requiring multiple separate adapters.
3Ease of operation
If the AC input connector is rigid, then structural stability is maintained, but storage and travel are cumbersome
Solution Approach 1:
The AC input connector is designed to be flexible rather than rigid, allowing it to bend and fold. This dynamic design enables the connector to be compacted for easy storage and travel, while still maintaining sufficient structural stability during use through its material properties and connection mechanism.
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
Enables continuous mobile use of electronic devices during recharging by providing a compact, wireless charging solution that is less cumbersome and allows for fast charging of internal batteries without the need for charging cables.
Implementation Method 1
The first housing is provided with a first status LED to indicate state of charge... The first status LED may glow a red color to indicate that the charging device requires charging. The first status LED may glow a green color to indicate that the charging device is satisfactorily charged... each of the charging jacks are provided with a second status LED. The second status LED may glow a red color to indicate that the charging device requires charging. The second status LED may glow a green color to indicate that the charging device is satisfactorily charged.
