Solution Overview
Problem
Existing wireless power transmission technologies fail to provide a compact charging solution that allows a receiver assembly to be housed within a transmitter assembly, necessitating additional space for bulky batteries or requiring complex directional alignment.
Innovation Solution
A power transmitter assembly with a housing that houses a processor and power transmission circuit, and a power reception assembly with a receiver housing and power storage, allowing the receiver assembly to be selectively coupled to an electronic device via an electrical port, enabling both wired and wireless charging without excessive space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If wireless power transmission components are arranged with a transmitter assembly and a separate receiver assembly, then wireless power transmission is achieved, but the device occupies excessive space and requires complex directional alignment
Solution Approach 1:
The patent combines the transmitter assembly and receiver assembly into a single integrated charging device. The receiver assembly is housed within the transmitter assembly, allowing both wireless transmission and reception functions to coexist in one unit, eliminating the need for separate components and complex alignment procedures.
Solution Approach 2:
The receiver assembly is nested within the transmitter assembly housing. This nested configuration allows the receiver to be stored inside the transmitter when not in use, minimizing the overall device footprint and eliminating the need for separate receiver units that would require alignment with the transmitter.
2Volume of moving object
If a receiver assembly is housed within a transmitter assembly, then space efficiency is improved, but the device complexity increases
Solution Approach 1:
The charging device is segmented into distinct functional assemblies (transmitter assembly with transmission circuit, receiver assembly with reception circuit, and electrical connector assembly). This segmentation allows for modular design and manufacturing while maintaining the integrated nested structure, making the complex system more manageable and manufacturable.
Solution Approach 2:
The integrated charging device performs multiple functions: wireless power transmission, wireless power reception, and wired charging through the electrical connector. This multi-functionality consolidates what would otherwise require separate devices into one unit, justifying the increased structural complexity through enhanced versatility.
