Network Card Device for Dynamic Router Sleep and Wakeup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable wireless routers consume high power in normal mode, leading to short battery life, and the sleep mode, while reducing power consumption, requires manual user intervention for wake-up and has high power consumption in poor network environments, and is inconvenient for users.
Innovation Solution
A network card device and routing system that automatically detect when to enter sleep or quasi-power-off modes based on user access and traffic, using an automatic wake-up/command to transition back to normal mode without user intervention, reducing power consumption and increasing battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the portable wireless router enters sleep mode to reduce power consumption, then battery life is extended, but the user must manually press keys to wake up the router which is inconvenient
Solution Approach 1:
The network card device performs preliminary actions by detecting the router's sleep state and automatically sending wake-up commands before the user needs to access the router. This eliminates the need for manual key pressing while maintaining power savings, as the system proactively prepares the router for upcoming user needs based on detection algorithms.
Solution Approach 2:
The system implements self-service through automatic detection and wake-up mechanisms. The network card device monitors the router's state and autonomously triggers wake-up sequences without requiring user intervention. This self-managing capability resolves the contradiction by maintaining power efficiency while eliminating manual operations.
2Ease of operation
If the portable wireless router remains in normal mode to ensure immediate access, then user convenience is improved, but power consumption is high and battery life is reduced
Solution Approach 1:
The system dynamically adjusts the router's operational state based on real-time conditions. Rather than maintaining a fixed normal mode, the router transitions between sleep and active states according to detected user needs and network conditions. This dynamic adaptation allows the system to optimize both power consumption and access speed by being active only when necessary.
Solution Approach 2:
The system changes operational parameters by transitioning the router between different power states (normal mode, sleep mode, and wake-up transitions). These parameter changes enable the router to consume minimal power during idle periods while rapidly transitioning to full operational capacity when access is needed, thus resolving the contradiction between power savings and immediate availability.
3Use of energy by stationary object
If the portable wireless router enters sleep mode to save power, then power consumption is reduced, but the router requires manual wake-up which increases operation time and user effort
Solution Approach 1:
The network card device performs preliminary detection and trigger actions to wake up the router before the user actually needs to access it. By anticipating user needs through detection algorithms, the system initiates wake-up sequences in advance, eliminating the time loss associated with manual wake-up operations while maintaining power savings during genuine idle periods.
Solution Approach 2:
The system implements feedback mechanisms where the network card device continuously monitors router state and user access patterns. This feedback loop enables the system to learn from usage behavior and optimize wake-up timing, reducing unnecessary wake-ups that waste power while ensuring timely wake-ups that minimize user waiting time. The feedback-driven approach resolves the contradiction by making wake-up decisions based on actual needs rather than fixed schedules.

AI summary
Disclosed is a network card device for realizing dynamic sleep and wakeup, for determining that a routing device has entered into a sleep mode or a quasi-power-off mode when no WiFi signal of the routing device is found, and sending automatic wake-up/power-on command to the routing device. Also disclosed is a routing device, for being woken up from a sleep mode to a normal mode or powered on and recovered from a quasi-power-off mode to the normal mode according to an automatic wake-up/power-on command. Also disclosed is a system composed of a network card device and a routing device. Also disclosed is a method for, when a user requests to access a routing device which has entered into a sleep mode or a quasi-power-off mode, being woken up from a sleep mode to a normal mode or powered on and recovered from the quasi-power-off mode to the normal mode according to automatic wake-up/power-on command.
