Solution Overview
Problem
Intelligent cabinets face issues with electromagnetic interference and power consumption due to wireless communication and separate power sources for driving devices, leading to signal interference and high power consumption.
Innovation Solution
The intelligent cabinet system incorporates a control device, power supply module, sensor, and communication device to manage power states and reduce interference by using wired connections and a sensor to switch between power saving and operating modes, along with a power supply module that includes a buck-boost charger and power storage unit for efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless communication is used between driving devices and control device, then wiring complexity is reduced, but electromagnetic interference and signal transmission delays occur
Solution Approach 1:
The system divides communication into two paths: wireless communication for remote control between the control device and external controllers, and wired communication for critical control signals between the control device and driving devices. This segmentation allows wireless convenience for user interaction while ensuring reliable wired communication for actuation commands, resolving the contradiction between reduced wiring complexity and maintained signal reliability.
2Device complexity
If each driving device uses a separate power source, then wiring complexity is reduced, but power consumption increases and power sources require replacement
Solution Approach 1:
The patent merges the power source function from individual driving devices into a centralized power supply module that provides power to all driving devices through the existing wired communication bus. This eliminates the need for separate batteries in each driving device, reducing overall power consumption while maintaining the wireless convenience benefit. The centralized power source is replaceable as a single unit rather than multiple distributed sources.
3Reliability
If continuous power supply is provided to driving devices, then operational readiness is maintained, but power consumption increases
Solution Approach 1:
The system implements periodic power supply to driving devices through the centralized power supply module, which activates power only when control signals are received or during scheduled intervals. The driving devices remain in a low-power standby state between activations, maintaining operational readiness through periodic power delivery rather than continuous supply. This resolves the contradiction by providing just enough power periodically to maintain functionality while significantly reducing overall energy consumption.

AI summary
An intelligent cabinet system includes a cabinet body, a plurality of movable members, a control device, a control unit, an electronic module, a power supply module, a sensor and a communication device. The control device is arranged on the cabinet body. The control unit is electrically connected to the control device. The electronic module is electrically connected to the control unit and includes a driving device for driving a drive member. The sensor senses whether a user is approaching the cabinet body. The communication device is configured to transmit a predetermined signal. When the control device receives the predetermined signal, the control device is configured to notify the control unit to control the driving device to move the driving member to switch from a first predetermined state to a second predetermined state, in order to allow one of the movable members to be moved away from the retracted position.
