Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging pads are used to charge wireless communication devices, then charging convenience is improved, but portability deteriorates and device size increases
Solution Approach 1:
The wireless communication device is designed to serve dual functions: it can both receive wireless charges and act as a wireless charging source for other devices. The power transmitting circuit and power receiving circuit are integrated into the same device, enabling it to function as both a charger and a chargeable device, thereby eliminating the need for separate charging pads while maintaining portability.
2Reliability
If users carry extra charging equipment to charge wireless communication devices, then charging availability is improved, but device complexity and burden increase
Solution Approach 1:
The patent merges the charging equipment functionality into the wireless communication device itself. The power transmitting circuit, power receiving circuit, and control logic are all integrated within the device boundaries, eliminating the need for external chargers, cables, and power adapters. Users only need to carry their wireless communication device to charge both their own device and other compatible devices.
3Reliability
If duplicate message transmissions are sent to multiple communication devices, then message delivery completeness is improved, but data throughput and resource utilization deteriorate
Solution Approach 1:
The system employs feedback mechanisms where the first wireless communication device monitors the charging status and communication state of the second device. Based on this feedback, the system intelligently determines whether to send duplicate messages or redirect messages through the charging connection, optimizing data throughput while ensuring message delivery completeness.
Solution Approach 2:
Instead of sending duplicate messages to multiple devices independently, the system inverts the approach by using the charging connection as a communication channel. Messages can be transmitted through the power transmission link, allowing the first device to communicate with the second device without duplicating transmissions over separate wireless communication channels, thereby improving data throughput.
