Wearable USB Device Athletic Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing athletic performance monitoring systems have limitations such as cumbersome data transfer to computers and limited ability to display performance data separately from audio players, and users prefer more flexible and user-friendly solutions for monitoring and recording athletic activities.
Innovation Solution
A wearable USB device with a water-resistant and impact-resistant housing, connected to a wristband, that communicates with sensors to record and monitor athletic performance, allowing data display and automatic upload to computers for further review, featuring a calibration module for accurate distance measurement and user interface for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If athletic performance monitoring systems use portable electronic devices to display data, then performance monitoring capability is improved, but device complexity and user convenience deteriorate when data transfer to computer is required
Solution Approach 1:
The system is divided into two functional parts: a wearable sensor unit for data collection and a USB device for data storage and transfer. This segmentation allows the monitoring function to remain simple and wearable while the data management function is handled by a separate, easily transferable USB device.
Solution Approach 2:
The USB device serves multiple functions: it acts as a data storage unit, a data transfer interface to computer, and a display device through its integrated screen. This multi-functionality eliminates the need for separate devices for each task, simplifying the overall system.
2Adaptability or versatility
If performance data is displayed on audio player, then integrated functionality is improved, but user flexibility deteriorates when users prefer separate data display
Solution Approach 1:
The system separates the audio player function from the performance monitoring display function. Users can choose to display performance data on the USB device's screen, on the audio player, or transfer data to computer for display, providing flexibility while maintaining integrated functionality through the USB interface.
Solution Approach 2:
The USB device acts as an intermediary between the sensor and various display devices (USB device screen, audio player, computer). This mediator allows data to be routed to different destinations based on user preference, maintaining versatility while enabling flexibility.
3Loss of information
If data transfer to computer is implemented, then data analysis capability is improved, but user convenience deteriorates when transfer process is cumbersome
Solution Approach 1:
The USB device pre-formats and stores data in a computer-readable structure during the athletic activity. This preliminary organization of data eliminates the need for complex data processing or conversion during transfer, making the computer upload process simple and convenient while preserving full data analysis capability.

AI summary
A wearable device has a carrier having an aperture. A device has a USB connection and a protrusion wherein the protrusion is received in the aperture to connect the device to a wristband. The device is a USB type device having athletic functionality. The device may further be configured to receive calibration data such that a measured distance may be converted to a known distance based on athletic activity performed by a user.
