Solution Overview

Problem

Wearable computing devices face limitations in battery life due to power consumption by applications, which restricts the complexity and richness of user interfaces and data availability, particularly in workout applications.

Innovation Solution

Implement a method on the computing device to manage activity information by starting and stopping location services based on workout behavior, using odometry data to conserve battery power and reconstruct workout routes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If background functions are turned off to conserve battery power, then battery life is extended, but data availability to applications is limited and user interface complexity is reduced

Engineering Contradiction:

Improvebattery lifeVSAvoiddata availability

Core Design Contradiction:

Duration of action of moving objectVSLoss of information

Solution Approach 1:

The system performs preliminary actions by collecting and storing odometry data and location data before the user actually needs the workout information. The workout application collects odometry data from sensors and location data from location services in advance, storing them for later use when the user views workout summaries or routes, thus maintaining data availability without continuous power consumption during the workout itself

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments data collection into different phases: pre-workout data collection (odometry data before workout starts), during-workout data collection (location data when location service is active), and post-workout data aggregation. This segmentation allows the system to minimize power consumption during critical workout periods while maintaining data availability through stored preliminary data

Inventive Principle:

Principle #1Segmentation

2Loss of information

If location services run continuously to provide rich workout data, then data collection is comprehensive, but battery power is consumed rapidly

Engineering Contradiction:

Improvedata collection completenessVSAvoidbattery power consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The system implements periodic action by activating location services only at specific intervals and conditions rather than continuously. The workout application activates location services periodically during the workout based on detected behavior characteristics, and collects location data only when needed, significantly reducing overall power consumption while maintaining comprehensive data collection for workout summaries and route reconstruction

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies dynamics by making the location service state changeable - the system dynamically transitions location services between active and inactive states based on real-time workout detection. When workout behavior is detected, location services are activated; when not detected, they remain inactive, optimizing the balance between data collection completeness and power consumption

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If processing background functions to collect comprehensive workout data, then user interface richness is improved, but device complexity increases

Engineering Contradiction:

Improveuser interface richnessVSAvoidprocessing complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary - the workout application itself - that mediates between the raw sensor data and the user interface requirements. The workout application collects odometry data from sensors and location data from location services, processes this data into meaningful workout summaries and reconstructed routes, and presents it through the user interface. This intermediary layer simplifies the overall system architecture by centralizing data processing logic in a dedicated application rather than requiring complex background processing across multiple systems

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method for data routing in wearable devices is disclosed. The method can include receiving first odometry data, starting a first location service on the computing device that generates first location data, generating a workout alert after a period, receiving a user selection responsive to the workout alert, starting a second location service on the computing device, stopping the first location service on the computing device, and recording second location data of the second location service and second odometry data. The steps may also include stopping the second location service on the computing device, and reconstructing a route corresponding to a path traveled by the computing device based on the first odometry data, the first location data, the second odometry data, and the second location data.
