Solution Overview
Problem
Traditional data transmission devices face challenges in balancing space and efficiency, leading to slow response times and low work efficiency due to the need for excessive power supply capacity and volume, which affects the 'Plug and Play' experience during projection.
Innovation Solution
Incorporating a microcontroller, vibration sensor, and controllable switch, the device powers up only when moved, initiating communication configuration before connection to an electronic device, reducing constant power consumption and optimizing power supply capacity.

1Productivity
If a power supply is arranged in the data transmission device to supply power to the data transmission module continuously, then the response speed and work efficiency are improved, but the capacity and volume of the power supply increase, occupying excessive space
Solution Approach 1:
The data transmission module performs configuration operations (initialization, driver loading, parameter setting) in advance before actual data transmission begins. The module is kept in a standby state with critical components powered, allowing immediate response when connection is established, eliminating the need for large-capacity continuous power supply
Solution Approach 2:
The power supply system transitions from static continuous power delivery to dynamic on-demand power management. The module alternates between low-power standby mode and full-power operation mode, with power supplied only when vibration detection indicates imminent connection, optimizing the balance between response speed and power consumption
2Volume of stationary object
If the data transmission module remains in power-off state to reduce power supply capacity, then the power supply volume is reduced, but the configuration time increases and response speed decreases
Solution Approach 1:
Critical initialization processes are executed in advance during standby mode, including loading communication drivers, configuring protocol parameters, and establishing basic connectivity settings. This preliminary configuration ensures that when the module transitions to full operation, only final connection steps remain, dramatically reducing configuration time
Solution Approach 2:
Different components of the data transmission module are powered at different times and with different power levels. Critical components (processor, memory, communication interface) are kept in low-power standby, while non-critical components are powered only when needed, achieving selective power management that balances speed and energy consumption

AI summary
This application provides a data transmission method and a data transmission device. The data transmission device is provided with a microcontroller, a power supply, and a vibration sensor. When the vibration sensor detects that the user moves the data transmission device, the microcontroller controls the power supply to supply power to the data transmission module, so that the data transmission module starts to activate before the data transmission device is connected to the electronic device, thereby improving the response speed and working efficiency of the data transmission device, meanwhile the power supply does not need to supply power to the data transmission module constantly, which reduces the capacity and volume of the power supply.
