Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing devices face challenges in managing power consumption and convenience when activating communication channels like Bluetooth, WiFi, and cellular signals, as leaving them on continuously drains battery life, while manually turning them on and off is inconvenient and prone to missed connections.
Innovation Solution
The implementation of a low-power wakeup transceiver that continuously detects beacons or signals from nearby devices, allowing the device to activate necessary communication channels automatically, reducing power consumption and eliminating the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication channels (Bluetooth, WiFi, cellular) are kept active continuously, then the device can detect and respond to connection signals immediately, but power consumption increases significantly
Solution Approach 1:
The communication system is segmented into two distinct components: a low-power wakeup receiver that continuously monitors for connection signals, and the full communication channel components that remain inactive until needed. This segmentation allows the device to maintain connection detection capability while dramatically reducing power consumption by keeping only the minimal necessary component active.
Solution Approach 2:
Instead of continuous operation, the full communication channels are activated periodically or on-demand based on wake-up signals from the wakeup receiver. The system transitions from a state of continuous monitoring to periodic activation, where the wakeup receiver operates continuously at low power and triggers full communication channel activation only when a connection signal is detected.
2Use of energy by moving object
If communication channels are turned off to conserve power, then battery life is extended, but the user must manually activate them which is inconvenient and can result in missed connections
Solution Approach 1:
The wakeup receiver enables the communication system to activate itself automatically in response to detected connection signals. Instead of requiring manual user intervention to turn on communication channels, the system performs self-service by monitoring for wake-up signals and autonomously activating the appropriate communication channels, thereby eliminating the inconvenience of manual activation while maintaining power savings.
Solution Approach 2:
The wakeup receiver performs preliminary monitoring and detection of connection signals before the full communication channels are activated. This preliminary action allows the system to prepare for communication by detecting incoming signals and triggering channel activation in advance, ensuring no connections are missed while avoiding unnecessary continuous operation of power-intensive components.
3Extent of automation
If the wakeup receiver continuously monitors for signals, then automatic channel activation is enabled, but the device complexity increases
Solution Approach 1:
The wakeup receiver is designed as a multi-functional component that can detect various types of connection signals (Bluetooth, WiFi, cellular) and trigger appropriate communication channels. By making the wakeup receiver universal in its signal detection capability, the system reduces overall complexity compared to having separate monitoring mechanisms for each communication type, while still enabling automatic activation of multiple different communication channels.

AI summary
Computing devices can utilize various low power wakeup transceivers in order to control functional states of various components of those devices. Each transceiver can broadcast a beacon including appropriate information, which can be received by any other device with a transceiver that is within a propagation range of the beacon. A transceiver receiving the beacon can cause the received beacon to be analyzed by appropriate decision logic, which can determine any appropriate functionality to be activated or otherwise contacted in response to the beacon. In at least some embodiments, the beacon can cause another type of communication channel to be activated to establish communications with a device from which the beacon was received. In this way, the communications channel can be established without having to leave the channel active or manually activate that channel.
