Wireless Power Receiving Module for Standard Battery Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small electronic devices face challenges in accommodating power receiving modules for wireless power transfer due to size constraints, as integrating all necessary circuits within a small battery compartment is difficult, and enlarging the module may prevent attachment to devices designed for standard batteries.
Innovation Solution
A power receiving module is designed with a first portion matching the shape of a standard battery and a second portion resembling a battery lid, allowing it to be attached to existing devices, while incorporating power receiving circuits within the device's housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power receiving module includes all necessary power receiving circuits, then wireless power transfer capability is achieved, but the module size increases and cannot be attached to small electronic devices
Solution Approach 1:
The power receiving module is divided into a first portion (battery-shaped) and a second portion (lid-shaped), separating the wireless power receiving circuits from the battery compartment. This segmentation allows the critical power receiving functionality to be integrated while maintaining compatibility with small battery housings.
Solution Approach 2:
The first portion of the power receiving module is designed to fit within the standard battery housing space, nesting the wireless power receiving circuits inside the existing battery compartment dimensions. This nesting approach enables integration without increasing the overall device volume.
2Reliability
If all power receiving circuits are integrated within the battery compartment, then wireless power transfer is achieved, but the battery housing space is insufficient
Solution Approach 1:
The power receiving module extends beyond the traditional battery form factor by adding a second portion that resembles a lid. This dimensional extension provides additional space for housing power receiving circuits while maintaining a compact profile that fits within existing battery compartments.
