Solution Overview
Problem
Current earphone charging cases and power adapters are separate, single-function products with limited use and structural homogeneity, leading to increased accessory needs and reduced convenience.
Innovation Solution
An earphone charging case with integrated AC/DC conversion, DC power output, and earphone charging circuits, including a USB power output interface, which combines the functions of both, allowing for simultaneous charging of earphones and mobile terminals using a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If earphone charging case and power adapter are made as separate single-function products, then each product has simple structure and clear function, but the number of accessories increases and convenience decreases
Solution Approach 1:
The patent merges the power adapter function and earphone charging case function into a single integrated device. The power adapter module and charging case module are combined in one housing, allowing the device to both charge earphones and provide power output to mobile terminals simultaneously, thereby reducing the number of accessories needed and improving versatility.
Solution Approach 2:
The integrated charging case is designed to perform multiple functions: charging earphones internally, providing USB power output to charge mobile terminals, and acting as a power bank. This multi-functional design eliminates the need for separate power adapters and charging cases, solving the contradiction between versatility and complexity by creating a universal device that handles multiple charging needs.
2Ease of operation
If separate power adapter and charging case are used, then each product can be optimized for its specific function, but the total number of accessories increases and portability decreases
Solution Approach 1:
By combining the power adapter and charging case into one integrated unit, the patent reduces the quantity of accessories from two separate products to one unified device. The integrated design maintains both functions while improving ease of operation, as users only need to carry one device instead of multiple accessories.
Solution Approach 2:
The universal charging case can charge earphones, charge mobile terminals via USB output, and function as a portable power bank. This multi-functionality directly addresses the contradiction by reducing accessory quantity while maintaining or improving convenience, as a single device replaces multiple specialized products.
