Wearable Device Barometer Vertical Velocity Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sports data recording devices, such as GPS-enabled devices, measure horizontal displacement rather than vertical displacement, failing to accurately reflect the exercise intensity of athletes in sports involving vertical movement like mountaineering or skiing.
Innovation Solution
A wearable device equipped with a barometer and processor that calculates a first time stamp for climbing initiation, determines single-lap climbing altitude, acquires a second time stamp based on preset altitude, calculates climbing time, and computes single-lap vertical velocity, allowing for real-time data filtering and display to assist users in planning and adjusting their exercise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning technology is used to measure horizontal displacement distance, then the measurement can be performed with existing technology, but the measurement cannot reflect the actual exercise situation of the athlete in vertical displacement sports
Solution Approach 1:
The patent replaces GPS positioning technology with barometer-based altitude measurement technology. The barometer measures vertical displacement through altitude changes, which directly reflects the actual exercise intensity in sports like mountaineering and skiing, thereby resolving the contradiction between measurement precision and adaptability to vertical displacement sports.
2Measurement precision
If barometer data is used to calculate vertical velocity and climbing altitude, then accurate real-time data can be obtained, but data filtering and processing complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the processor continuously compares the current altitude with the previous altitude to determine climbing status. This feedback loop enables real-time data filtering and processing, allowing the system to accurately calculate vertical velocity and climbing altitude while managing data processing complexity through systematic comparison and validation.
