Solution Overview
Problem
Current wearable devices operate independently, leading to inefficient management of sensing and computing resources, resulting in sub-optimal power consumption and network load due to redundant sensor data collection and transmission, which reduces battery life and increases network bandwidth usage.
Innovation Solution
A system with a base wearable device controlling multiple satellite devices, optimizing sensor data production and power consumption by identifying redundancies and consolidating sensor data processing, using a control hierarchy and decision-making programming that can be user or remotely adjustable, and incorporating a vendor-neutral API to integrate diverse wearable devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wearable devices operate independently and collect sensor data autonomously, then each device can maintain its own functionality and independence, but redundant sensor data is generated leading to increased power consumption and reduced battery life
Solution Approach 1:
The patent merges multiple independent wearable devices into a coordinated network where devices share sensor data and computing resources. The base device consolidates sensor data from satellite devices, eliminating redundant data collection and reducing overall power consumption while maintaining device functionality through networked collaboration
Solution Approach 2:
The base wearable device serves multiple functions: it acts as a satellite device itself, coordinates other satellite devices, consolidates sensor data, performs computing tasks, and manages data transmission. This multi-functionality reduces the need for each satellite device to independently perform all functions, thereby reducing their power consumption
2Reliability
If multiple wearable devices independently transmit sensor data to remote cloud locations, then each device maintains data upload capability, but network load increases due to redundant data transmission
Solution Approach 1:
The patent merges data transmission operations by having the base device consolidate sensor data from multiple satellite devices before transmitting to cloud locations. This eliminates redundant data transmission over the network, reducing network load and energy consumption while maintaining reliable data upload capability through the coordinated base device
3Measurement precision
If redundant sensors remain active in multiple wearable devices, then complete sensing coverage is maintained, but battery life is reduced due to continuous operation
Solution Approach 1:
The patent applies partial action by having only the base device or selected satellite devices with superior sensors perform redundant sensing functions. Other satellite devices can reduce sensor activity or enter sleep modes for non-critical measurements, maintaining adequate sensing coverage while extending battery life through selective sensor operation
Solution Approach 2:
The system implements feedback mechanisms where the base device evaluates sensor data quality and coordinates satellite devices to adjust their sensing activity. When sufficient data is already available from the base or other satellites, feedback signals trigger satellite devices to reduce or pause redundant sensing, thereby extending battery life while maintaining measurement precision
