Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging devices are connected to a power source, then power can be supplied to devices, but their availability is limited to the proximity of power sources
Solution Approach 1:
The patent introduces a wireless charging relay as an intermediary device that receives power from traditional power sources and retransmits it wirelessly. This relay acts as a mediator between the power source and charging devices, enabling wireless charging without direct connection to power outlets and extending charging availability beyond proximity limitations.
Solution Approach 2:
The patent replaces the mechanical connection (power line/outlet connection) with a wireless power transmission system. The relay converts wired power input into wireless power output, substituting the mechanical plug-and-play system with electromagnetic field-based power transfer, thereby eliminating the need for physical connection to power sources.
2Reliability
If wireless charging is limited to specific power source types, then device compatibility can be maintained, but charging flexibility is reduced
Solution Approach 1:
The wireless charging relay is designed with multi-functionality to handle multiple power input types (AC power, DC power, other wireless power sources) and convert them into appropriate wireless power output formats. This universal design enables the relay to work with various device types and power sources, simultaneously maintaining compatibility standards while providing charging flexibility across different scenarios.
Solution Approach 2:
The relay dynamically adjusts power transmission parameters such as frequency, power level, and transmission mode based on the detected device type and power source characteristics. By changing these parameters, the system maintains reliable compatibility with different devices while adapting to available power sources, thus achieving both reliability and flexibility.
