Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices with limited battery power face high power consumption due to frequent wireless signal measurements, reducing their standby time when connected to cellular mobile communication networks.
Innovation Solution
A method where a communication device with limited battery power instructs a communication device with more power to perform wireless signal measurements, sharing the results via a shorter-range network, thereby reducing power consumption and extending standby time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wearable device performs wireless signal measurements for cell handover, then the device can maintain proper network connectivity and handover capability, but the device experiences high power consumption and reduced standby time
Solution Approach 1:
The patent introduces a server as an intermediary to perform signal measurements on behalf of the wearable device. The server receives measurement configurations from the network, executes the measurements, and returns results to the wearable device via a short-range communication connection. This mediator approach allows the wearable to maintain network connectivity without directly performing power-intensive measurements.
Solution Approach 2:
The wearable device creates a short-range communication connection with a terminal device (such as a smartphone) that has greater computing power and battery capacity. The terminal device copies the measurement capabilities of the wearable, performing the actual signal measurements while the wearable receives the results. This copying approach enables the wearable to function as if it performed measurements without bearing the power consumption burden.
2Speed
If a wearable device performs frequent signal measurements to maintain handover capability, then the device can respond to network changes promptly, but the standby time is significantly reduced
Solution Approach 1:
The server acts as a mediator that handles the computationally intensive measurement tasks, allowing the wearable device to maintain fast handover response through the short-range connection without performing the actual measurements. The server processes measurements in the background and delivers results quickly when needed.
Solution Approach 2:
The patent replaces the mechanical approach of the wearable device directly performing measurements with its own hardware resources with a distributed approach where measurement tasks are offloaded to a terminal device or server. This substitution leverages the terminal's greater computational resources while maintaining the wearable's rapid response capability through efficient data exchange over short-range communication.
