Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPS-based mobile devices lack accurate real-time performance comparison features, as they fail to account for route elevation changes and GPS signal dropouts, leading to inaccurate distance and time measurements.
Innovation Solution
A system and method that utilize a network service to generate comparative data points by synchronously sending measured GPS locations to a network service, which derives statistics based on predefined route data, allowing users to measure relative performance during route traversal, including displaying rankings and real-time feedback through the mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS-based mobile devices are used for performance tracking, then location awareness is provided, but measurement precision deteriorates due to GPS signal dropouts and lack of elevation data
Solution Approach 1:
The patent combines multiple data sources (GPS locations, route elevation data, predefined route geometry) into a unified performance tracking system. By merging these disparate elements, the system compensates for GPS signal weaknesses with supplementary data, achieving accurate distance and time measurements even when GPS signal reliability deteriorates
Solution Approach 2:
The patent introduces a network service as an intermediary that processes measured locations against predefined route data and elevation information. This intermediary layer transforms raw, potentially unreliable GPS measurements into accurate performance metrics by comparing them with known route characteristics, thereby resolving the contradiction between measurement precision and GPS signal reliability
2Adaptability or versatility
If real-time performance comparison is implemented, then user motivation is enhanced, but device complexity increases due to network service integration
Solution Approach 1:
The network service acts as an intermediary that handles the complex tasks of data processing, comparison, and feedback generation. By offloading these functions from the mobile device to a remote server, the system achieves sophisticated real-time performance comparison capabilities while keeping the device itself relatively simple
Solution Approach 2:
The network service provides universal functionality by handling multiple tasks: receiving location data, comparing performance against targets, generating feedback, and managing route information. This multi-functional approach allows the system to achieve high adaptability without increasing individual device complexity, as the complexity is centralized in the network service

Data Source
AI summary
Real time performance comparison involves identifying predefined route data corresponding to a route. Measured locations are detected while a user traverses the route carrying a mobile device. The measured locations are sent via a network synchronously with the detection of the respective measured locations. Comparative data points are derived based on the predefined route data and the measured locations in response to receiving the measured locations. The comparative data points are sent, via the network, in response to measured locations. The comparative data points allow the user to measure relative performance during the route traversal.
