Wireless Device Parameter Detection for Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless devices continuously search for networks and updates even when not in use, leading to unnecessary power consumption and battery drain.
Innovation Solution
A wireless device with a parameter detecting component that generates a wake-up signal based on detected parameters such as GPS signals or pressure, allowing it to only upload or download data when in use or at appropriate locations.

Engineering Contradiction Analysis
1Speed
If the wireless device continuously searches for networks and updates, then the device can quickly access data when needed, but the power consumption increases and battery life decreases
Solution Approach 1:
The device transitions from continuous network searching to periodic wake-up cycles. The processor enters low-power sleep mode between wake-up events, only activating periodically to check for networks and updates. This periodic operation maintains data access capability while dramatically reducing average power consumption compared to continuous operation.
Solution Approach 2:
The device performs wake-up and network checking actions in advance of when data transfer is actually needed. By waking up periodically before the user likely needs data access, the device ensures readiness without requiring continuous active monitoring, thus balancing speed of access with energy conservation.
2Use of energy by moving object
If the wireless device remains idle and inactive, then power consumption is reduced, but the device cannot receive updates or transmit data when needed
Solution Approach 1:
The system uses feedback from wake-up triggers (manual activation, scheduled intervals, or external signals) to determine when the device should become active. This feedback mechanism ensures the device wakes up at appropriate moments to perform data transmissions or receptions, maintaining reliability while spending most time in low-power state.
Solution Approach 2:
The device autonomously manages its own wake-up schedule and power state transitions without requiring continuous external control. It automatically activates when needed based on internal timing mechanisms or external wake-up signals, then returns to sleep mode, providing self-regulating power management that balances reliability and energy efficiency.

AI summary
A device for use with a wireless transceiver that is operable to transmit a data file. The device includes a communication component, a processing component, a parameter detecting component and a controlling component. The communication component wirelessly communicates with the transceiver. The processing component operates in a first manner. The parameter detecting component detects a first parameter and generates a parameter signal based on the detected first parameter. The controlling component generates a wake-up signal based on the parameter signal. The communication component can further receive the data file based on the wake-up signal. The processing component can further operate in a second manner based on the data file.
