Adaptive Sensor Module for Multi-Sport Performance Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal performance monitoring systems for sports require multiple sensor modules for different types of sports items, leading to inefficiencies and increased complexity, as they lack the ability to adapt their operation based on the specific sports item being used.
Innovation Solution
A sensor module with a wireless communication unit and a host identification circuit that can detect and communicate with a sports item's identification circuit, allowing it to adapt its operation and processing based on the received identifier, enabling a single module to be used across various sports items by initiating identification through a trigger and communicating with a slave identification circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensor modules are used for different sports items, then measurement precision and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The sensor module is designed with a universal interface and adaptive identification circuit that automatically detects and configures for different sports item types (ECG belt, EMG garment, foot pod, etc.). A single sensor module can serve multiple sports items through the identification circuit that reads item-specific identifiers and adjusts operational parameters accordingly, eliminating the need for multiple specialized modules while maintaining monitoring accuracy for each item type.
2Device complexity
If a single sensor module is used for multiple sports items, then device complexity is reduced, but adaptability to different item types deteriorates
Solution Approach 1:
The sports items are pre-equipped with identification circuits that store unique identifiers and configuration data before the sensor module attaches. When the sensor module connects to a sports item, the identification circuit automatically provides the item-specific information, allowing the sensor module to pre-configure its operational parameters, sampling rates, and measurement modes appropriate for that specific item type, thereby achieving high adaptability without increasing device complexity.
Data Source
AI summary
The invention relates to a sensor apparatus, comprising: a sensor unit, a wireless communication unit configured to directly or indirectly transmit and receive data to and from an external source, and means for receiving identification information from a sports item while being attached to the sports item, wherein the apparatus is initiate identification of the sports item in response to a trigger from an identification activation element in the sports item.
