Wearable Sensor Network for Running Form Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring running parameters do not effectively assess or improve a runner's form or technique, leading to inefficiencies in energy use and potential fatigue due to improper arm swing and torso motion.
Innovation Solution
A system comprising sensors worn on the wrist, foot, and torso that monitor arm swing synchronization, torso motion, and vertical displacement to provide real-time feedback and adjust threshold values based on running speed, helping runners maintain proper form by minimizing unnecessary energy expenditure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional running parameter monitoring systems are used, then speed, distance, and heart rate can be tracked, but form and technique cannot be assessed
Solution Approach 1:
The system divides the monitoring function into multiple specialized sensors placed at different body locations (torso sensor for vertical displacement, arm sensors for swing motion, leg sensors for stride analysis). Each sensor segment focuses on specific form parameters, enabling comprehensive technique assessment without requiring a single complex device
Solution Approach 2:
The monitoring system is designed to serve multiple functions: tracking traditional running parameters (speed, distance, heart rate) alongside form assessment (vertical displacement, arm swing synchronization, stride technique). This multi-functional approach allows one system to address both performance tracking and technique correction needs
2Use of energy by moving object
If runners maintain proper form through monitoring, then energy efficiency improves, but real-time feedback requires continuous data processing
Solution Approach 1:
The system pre-establishes optimal form thresholds and parameters for each runner based on their biomechanics and performance goals. By setting these reference values in advance, the system can quickly compare real-time sensor data against predetermined standards, enabling rapid feedback without complex real-time calculations
Solution Approach 2:
The system implements continuous feedback loops where sensor data is processed, compared against optimal form thresholds, and returned to the runner through visual or audible signals. This real-time feedback mechanism allows runners to self-correct their form during exercise, improving energy efficiency through automated guidance
3Measurement precision
If multiple sensors are deployed to monitor arm swing and torso motion, then form assessment capability improves, but device complexity increases
Solution Approach 1:
The system combines multiple sensor types (accelerometers, gyroscopes, magnetometers) into integrated sensor units that can be worn at key body locations. By merging these sensing capabilities into compact modules, the system achieves comprehensive form monitoring (vertical displacement, arm swing, torso rotation) without requiring numerous separate devices
Solution Approach 2:
The sensor system employs a hierarchical structure where multiple sensing elements are nested within integrated sensor units, which are then nested within the overall monitoring system architecture. This nested organization allows complex form assessment capabilities to be achieved through layered integration of simpler components
