Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging is used to recharge battery, then power delivery is reliable, but device mobility is limited and cord clutter increases
Solution Approach 1:
The patent replaces the mechanical wired charging system with a wireless power transfer system using electromagnetic fields. The transmitter generates an oscillating electromagnetic field that inductively couples with the receiver coil in the device, enabling power transfer without physical wire connection, thus eliminating cord clutter while maintaining charging functionality
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary medium to transfer power between the charging source and the device. The transmitter converts electrical power to an oscillating electromagnetic field, which then inductively couples to the receiver coil, serving as a non-contact intermediary that enables power delivery without direct wire connection
2Duration of action of moving object
If battery capacity is increased to meet power demands, then device runtime is extended, but device weight and volume increase
Solution Approach 1:
The patent enables preliminary power delivery to the device before actual use through wireless charging. The oscillating electromagnetic field can transfer power in advance, allowing the device to be charged quickly and efficiently without the need for large capacity batteries, thus extending runtime without proportionally increasing weight
Solution Approach 2:
The patent creates a wireless power transfer pathway that copies the functionality of wired power delivery through electromagnetic field coupling. This alternative power delivery method provides sufficient energy to meet device demands without relying on increased battery capacity, thereby avoiding the weight penalty of larger batteries
3Productivity
If multiple devices are connected to charging source via wires, then power delivery is achieved, but cord clutter increases
Solution Approach 1:
The patent creates a universal wireless charging field that can simultaneously serve multiple devices. The transmitter generates a broad electromagnetic field that can inductively couple with multiple receiver coils in different devices at the same time, providing multi-device charging capability without requiring separate wire connections for each device, thus eliminating cord clutter while maintaining charging productivity
