Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless charging is performed by aligning charging coils between electronic devices, then power transmission efficiency is improved, but device alignment precision and positioning accuracy become critical challenges
Solution Approach 1:
The patent replaces mechanical alignment systems with magnetic field-based detection and communication systems. The receiving device uses its charging coil to detect the transmitting device through electromagnetic coupling, and communication circuits exchange alignment information, eliminating the need for precise mechanical positioning mechanisms.
Solution Approach 2:
The patent introduces magnetic field detection and communication circuits as intermediaries between the charging coils. These intermediaries facilitate the exchange of positioning and alignment information, enabling the devices to automatically adjust their relative positions without direct mechanical intervention.
2Stability of the object's composition
If the display faces downward during wireless charging, then charging stability is improved, but the user cannot view or respond to notifications from other devices
Solution Approach 1:
The patent uses the wireless communication circuit as an intermediary to transfer notification information from the receiving device to the device being charged. The charged device then displays these notifications on its own display, allowing the user to view them without changing the physical orientation of the charging setup.
Solution Approach 2:
The patent makes the charged device serve multiple functions: it acts as both the charging recipient and a notification display device. This multi-functionality allows notifications to be viewed on either device depending on which display is more accessible to the user.
3Loss of information
If event notifications are transmitted between devices during wireless charging, then user awareness of external events is improved, but communication circuit complexity and power management requirements increase
Solution Approach 1:
The patent makes the existing communication circuits multi-functional by using them for both standard device communication and for transmitting charging-related event notifications. This eliminates the need for separate dedicated notification circuits during the charging process.
Solution Approach 2:
The patent merges the notification transmission function with the existing wireless communication system. By combining event notification delivery with the established communication protocols already in use during charging, the system avoids adding separate complex communication infrastructure.
