Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The effective charging area for wireless power transfer is limited to the dimensions of the transmitter device, making it challenging to continuously charge electronic devices that operate in various modes while maintaining the receiver within the charging range.
Innovation Solution
The electronic device incorporates a receiver coupled to a rechargeable battery, which can be wirelessly charged using technologies like magnetic resonance, inductive coupling, or capacitive coupling, and features a rotatable base member that allows the receiver to remain within the charging area across different operation modes, including tablet, stand, and clamshell modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the receiver is fixed in position within the electronic device, then the device structure is simple, but the receiver cannot remain within the effective charging area when the device operates in various modes
Solution Approach 1:
The base member is designed to be rotatable relative to the display member, allowing the receiver positioned in the base member to dynamically change its position and orientation. This rotational movement enables the receiver to remain within the transmitter's effective charging area regardless of whether the device is in tablet mode, stand mode, or clamshell mode, thus achieving adaptability without requiring multiple fixed receiver positions
2Reliability
If the base member is made thicker to house the receiver, then the receiver can be securely positioned, but the device becomes less portable and more cumbersome
Solution Approach 1:
The receiver is nested within the base member in a space-efficient manner, utilizing the internal volume of the base member to house the receiver components. This nesting approach allows the receiver to be securely positioned without significantly increasing the overall thickness of the base member or the electronic device, maintaining portability while ensuring reliable receiver positioning
