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

VSEngineering 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

Engineering Contradiction:
Improvedevice independenceVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvedata upload capabilityVSAvoidnetwork load
Core Design Contradiction:
ReliabilityVSLoss of energy

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvesensing coverageVSAvoidbattery life
Core Design Contradiction:
Measurement precisionVSDuration of action of stationary object

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

Inventive Principle:
Principle #16Partial or excessive action

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

Inventive Principle:
Principle #23Feedback
