Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different charging cables with different connectors are used for different electronic devices, then each device can be charged properly, but the user needs to carry and manage multiple cables, reducing convenience and versatility
Solution Approach 1:
The patent applies universality by designing a single charging cable system that can charge multiple types of electronic devices with different connectors. The cable includes a first connector compatible with one device type and a second connector compatible with another device type, allowing one cable to serve multiple functions and replace the need for multiple separate cables.
Solution Approach 2:
The charging cable is segmented into multiple connector types along its length. Instead of a single unified connector, the cable is divided into sections with different connector types (e.g., USB-C, Lightning, Micro-USB) that can be independently used to charge different devices, thereby solving the compatibility issue while maintaining a single cable structure.
2Reliability
If a direct physical connection via cable is used to charge electronic devices, then reliable power transfer is achieved, but the user must have direct access to power outlets and proper cables for each device, reducing flexibility
Solution Approach 1:
The patent introduces an intermediary wireless charging device that mediates between the power source and the electronic device. This device contains a transmitting coil that wirelessly transmits power to a receiving coil in the electronic device, eliminating the need for direct physical cable connections while maintaining reliable power transfer through electromagnetic induction.
Applied Scientific Principles

AI summary
A wireless charging device for use in providing electrical power to one or more portable electronic devices is provided. The wireless charging device includes a ferrous core and a housing surrounding the ferrous core. The housing includes a plurality of guides that align a cable. When the cable is aligned in the plurality of guides and a current is passed through the cable, the cable and the ferrous core act as a transmission coil to transmit power from an electrical power source to at least one receiving coil in a first portable electronic device.
