Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless power charging systems face inefficiencies due to the need for precise matching of charging schemes between the transmitter and receiver, which can lead to contact errors and reduced charging efficiency, especially when the transmitter's orientation differs from the receiver's.
Innovation Solution
A wireless power transmitter with multiple wireless transmitting units, including a first unit on the rear surface and a second unit on the side surfaces, each with a distinct charging scheme, allowing for flexible alignment and orientation to match various charging schemes of the receiver, thereby improving charging efficiency by spacing and aligning the units to avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single wireless transmitting unit with a fixed charging scheme is used, then the device structure is simple, but it cannot charge electronic appliances with different charging schemes
Solution Approach 1:
The wireless power transmitter is divided into multiple independent transmitting units (first wireless transmitting unit and second wireless transmitting unit), each capable of operating with different charging schemes. This segmentation allows the system to handle multiple charging schemes simultaneously while maintaining individual unit simplicity.
Solution Approach 2:
The transmitter is designed with multiple transmitting units that can serve different charging schemes (electromagnetic induction and electromagnetic resonance). The control unit selects which unit to activate based on the receiver's requirements, making the transmitter universal and adaptable to various electronic appliances.
2Adaptability or versatility
If multiple wireless transmitting units are used to support different charging schemes, then charging scheme compatibility is improved, but the device complexity increases
Solution Approach 1:
The control unit dynamically selects which transmitting unit to activate based on the charging scheme required by the electronic appliance. This dynamic selection mechanism allows the system to adapt to different charging needs without requiring all units to operate simultaneously, thereby managing complexity effectively.
Solution Approach 2:
Each transmitting unit is designed with specific local qualities - the first unit is optimized for electromagnetic induction while the second unit is optimized for electromagnetic resonance. This specialization allows each unit to be relatively simple while the combination provides comprehensive charging scheme support.
3Productivity
If wireless power transmitting units are spaced apart to avoid interference, then charging efficiency is improved, but the device area increases
Solution Approach 1:
The transmitting units are arranged in different spatial orientations and positions (rear surface versus side surfaces) rather than simply spreading them out in a single plane. This three-dimensional arrangement allows adequate spacing for efficiency while minimizing the overall footprint of the transmitter device.
