Detachable Wireless Charging Accessory for Portable Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless charging solutions for electronic devices are limited by the need for a fixed power source and lack of portability, as they often require a wired connection or a dedicated charging pad, which does not meet user demands for convenience and mobility.
Innovation Solution
An accessory device with a detachable design that integrates a battery and conductive patterns for wireless charging, allowing the electronic device to be charged while carried, using magnetic induction or resonance methods, and featuring a non-conductive housing for safety and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless charger is used with a fixed power source, then wireless charging function is achieved, but portability is reduced
Solution Approach 1:
The wireless charging system is divided into two independent parts: a portable accessory device containing a battery and wireless charging coil that can be detached, and a separate power source. This segmentation allows the wireless charging function to be portable while the power source remains stationary, resolving the contradiction between achieving wireless charging and maintaining portability.
Solution Approach 2:
The solution transitions from a two-dimensional problem (either fixed or portable) to a three-dimensional solution by separating the wireless charging functionality into a detachable accessory that can be carried independently from the power source, adding the dimension of separability and enabling both fixed and portable usage scenarios.
2Strength
If a protective cover is added to an electronic device, then aesthetic design and protection are improved, but device complexity increases
Solution Approach 1:
The protective cover is merged with wireless charging functionality by integrating a battery and wireless charging coil into the cover structure. This combination eliminates the need for separate protective cover and wireless charging device, reducing overall system complexity while providing both protection and wireless charging capabilities.
Solution Approach 2:
The accessory device serves multiple functions simultaneously: it acts as a protective cover for the electronic device, provides wireless charging capability through integrated coil and battery, and offers aesthetic customization. This multi-functionality reduces the need for multiple separate components, thereby reducing overall device complexity.

AI summary
An apparatus and a method for wirelessly charging are disclosed. An accessory device is detachably mounted on an electronic device. The accessory device includes a housing including a first face configured to oppose a face of the electronic device when the housing is mounted on the electronic device, a second face opposite to the first face, and a third face extending in a first direction from the first face so as to enclose at least a portion of a side face. The accessory device further includes a battery and at least one conductive pattern electrically connected to the battery. The accessory device can transmit power to the electronic device in a wireless manner and/or receive power from an external device in a wireless manner. Areas of the first face and the third face of the housing of the accessory device are formed of a non-conductive material.
