Low-Power Image-Forming Device Communication via Pre-Stored Service Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming devices in low power consumption mode cannot communicate with other devices due to the inability to respond to Bonjour service requests, limiting their functionality and user experience.
Innovation Solution
The electronic device pre-stores target data in a readable storage area before entering low power consumption mode, allowing it to respond to service requests and establish communication connections by sending the stored data to the requesting device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the image forming device enters low power consumption mode, then energy consumption is reduced, but communication functionality is lost
Solution Approach 1:
The patent applies preliminary action by storing target data (including device identification, IP address, port information, and service data) in a storage unit before entering low power consumption mode. This pre-stored data enables the device to respond to service requests even when the main control unit is dormant, thus maintaining communication capability while reducing power consumption.
Solution Approach 2:
The patent segments the system into a main control unit that can enter low power mode and a storage unit that remains accessible. By separating the data storage function from the processing function, the device can maintain communication readiness without keeping the entire system active, resolving the contradiction between power savings and communication availability.
2Loss of energy
If functional modules are dormant in low power consumption mode, then energy consumption is reduced, but service responsiveness is lost
Solution Approach 1:
The patent introduces an intermediary mechanism where the storage unit acts as a mediator between the dormant main control unit and incoming service requests. When a service request is received, the device retrieves pre-stored target data from the storage unit to construct a response, enabling service responsiveness without activating the main control unit.
Solution Approach 2:
By preliminarily storing all necessary communication data (device identification, network parameters, service information) before entering low power mode, the system ensures that service responses can be generated using pre-prepared information, maintaining reliability while minimizing energy consumption.
3Use of energy by stationary object
If the device cannot reply to Bonjour data in low power mode, then power consumption is reduced, but user experience deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-storing Bonjour service data and device identification information in the storage unit before entering low power consumption mode. This allows the device to automatically reply to Bonjour service requests using pre-prepared data, maintaining discoverability and ease of operation while in low power mode.
Solution Approach 2:
The system implements self-service by automatically constructing and sending service response data using pre-stored information when Bonjour requests are received, without requiring user intervention or activation of the main control unit. This maintains user experience while preserving power savings.

AI summary
Embodiments of the present disclosure provide a communication method, a control apparatus, an electronic device, and a storage medium. The method includes: when an electronic device is in a low power consumption mode, in response to a target service request message, sending target data to a target device to allow the target device to establish a communication connection with the electronic device according to the target data, where the target device is a device that sends the target service request message.
