Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless charging solutions for handheld devices require design modifications and occupy the existing wired charging interface, increasing manufacturing costs and user complexity.
Innovation Solution
A wireless charging jacket integrated with a battery, featuring an induction coil, control circuit, isolation gasket, and conductive terminal, which allows for wireless charging without modifying the handheld device or battery design, using electromagnetic induction to charge the battery via a package material that covers and securely fixes the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless charging receiver is designed on the backplate of handheld device, then wireless charging function is achieved, but manufacturing cost increases and device complexity increases due to design modifications and extra terminals
Solution Approach 1:
The wireless charging receiver is separated from the handheld device and integrated into the battery pack instead. This segmentation allows the battery pack to independently provide wireless charging capability without requiring modifications to the handheld device structure, terminals, or circuitry.
Solution Approach 2:
The battery pack is designed to serve multiple functions: it acts as both the power source for the handheld device and the wireless charging receiver. By integrating the wireless charging receiver into the battery pack, a single component (battery pack) performs both energy storage and wireless power reception functions.
2Adaptability or versatility
If wireless charging receiver is designed as cover of handheld device, then wireless charging function is achieved, but wired charging interface is occupied causing user complexity
Solution Approach 1:
The wireless charging receiver is segmented away from the handheld device body and placed in the battery pack. This physical separation ensures that the wired charging interface of the handheld device remains accessible and unaffected, as the wireless charging function is now provided by the battery pack itself rather than through a cover that would block the interface.
3Adaptability or versatility
If wireless charging receiver is integrated into handheld device, then wireless charging function is achieved, but manufacturing cost increases
Solution Approach 1:
The wireless charging receiver is merged with the battery pack, which is a separate component from the handheld device. This combining approach allows the wireless charging functionality to be added to an existing component (battery pack) that is already part of the device assembly, avoiding the need for additional manufacturing steps or cost increases for the handheld device itself.
