Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless earpieces require multiple pins for charging and communication, leading to a bulky appearance and high configuration costs, which contradicts the miniaturization and aesthetic goals of true wireless interconnected stereo (TWS) earpieces.
Innovation Solution
A communication control method that uses the two power supply pins for both charging and communication by controlling the output voltages to interchange with each other, allowing the wireless earpiece to receive data during charging without the need for power line communication, thus reducing the pin area and configuration costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three additional pins (detection, TX, RX) are added for communication during charging, then communication function is improved, but the area occupied by pins increases and appearance becomes cumbersome
Solution Approach 1:
The two power supply pins are made to serve dual functions: charging and communication. By controlling the output voltages of these pins to interchange, the system enables data transmission during charging without requiring separate communication pins, thus reducing the total pin area while maintaining communication capability
Solution Approach 2:
The charging and communication functions are merged into a single pin interface. The patent combines the power supply pins to carry both power and data signals by dynamically switching their voltage roles, eliminating the need for separate communication pins and reducing overall pin count
2Adaptability or versatility
If power line communication is applied for communication during charging, then communication function is improved, but configuration cost increases due to dedicated chip requirement
Solution Approach 1:
The existing power supply pins and voltage control mechanisms are made to serve the additional communication function. By utilizing the voltage interchange capability already present in the charging system, the patent avoids the need for dedicated communication chips or power line communication modules, thereby reducing configuration costs while enabling communication during charging
3Adaptability or versatility
If multiple pins are used for both charging and communication, then communication capability is improved, but the aesthetic appearance and miniaturization are compromised
Solution Approach 1:
The power supply pins are designed to perform multiple functions including charging and communication. By making these pins multi-functional through voltage interchange, the patent reduces the total number of pins required, leading to a more compact and aesthetically pleasing design that maintains full communication capability

AI summary
Disclosed by the present invention are a communication control method, device and system, a charging box and a wireless earpiece, the method comprising: when charging a first wireless earpiece by means of two power pins, the charging box obtains first data to be sent if communication with the first wireless earpiece is needed; and according to the first data to be sent, the charging box controls the output voltages of the two power pins to be correspondingly exchanged, so that the first wireless earpiece switches according to the output voltage of a corresponding power pin so as to obtain the first data to be sent during the charging process. In the present method, the charging box controls the output voltages of the two power pins to be correspondingly exchanged according to the first data to be sent, so that the wireless earpiece may obtain the first data to be sent according to the switching of the charging voltages when using the switchable charging voltages of the two power pins to perform charging. Therefore, the wireless earpiece uses the two pins used for charging to communicate with the charging box during the charging process, thereby reducing the setup cost and taking both a small size and aesthetic appearance into account.
