Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data collection systems in sports and activities fail to accurately gather and transmit comprehensive data, such as impact force, trajectory, speed, and environmental conditions, during object interactions like a bat and ball, leading to incomplete analysis of participant performance and potential injuries.
Innovation Solution
A portable wireless apparatus embedded with sensors like GPS, Accelerometer, Gyroscope, Magnetometer, Barometer, and Thermometer, which collects and transmits data via wireless networks to a central server for real-time analysis, including force exerted, energy transmission, and trajectory details of the object in motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a portable wireless apparatus with multiple sensors is embedded in the object to collect comprehensive data, then the measurement precision and completeness of impact data is improved, but the device complexity and weight of the object increase
Solution Approach 1:
The patent combines multiple sensor functions (accelerometer, GPS, gyroscope, magnetometer, barometer, thermometer) into a single integrated portable wireless apparatus that is embedded in one object. This merging approach allows comprehensive data collection while reducing the number of separate devices needed, thereby improving measurement precision without proportionally increasing overall system complexity.
Solution Approach 2:
The portable wireless apparatus is designed as a multi-functional device that can collect various types of data (motion, location, environmental conditions) from different objects it comes into contact with. This universal design allows a single device to perform multiple measurement functions, improving data completeness while managing device complexity through consolidation.
2Productivity
If real-time data transmission is implemented during object motion, then the productivity and responsiveness of the system is improved, but the energy consumption increases
Solution Approach 1:
The system implements periodic data transmission rather than continuous transmission, where data is collected and transmitted at specific intervals or triggered by certain events (such as impact detection). This periodic approach maintains high productivity by ensuring data is captured and communicated efficiently while significantly reducing energy consumption compared to continuous operation.
Solution Approach 2:
The apparatus uses its own sensors to detect when data transmission is necessary (e.g., detecting impact events or motion thresholds), allowing the system to automatically manage its own energy resources by transmitting data only when relevant, thereby improving productivity without excessive energy consumption.
3Loss of information
If comprehensive environmental and motion data is collected from multiple sensors, then the loss of information is reduced, but the quantity of data to be processed and transmitted increases
Solution Approach 1:
The system extracts and prioritizes only the most relevant data from the comprehensive sensor dataset for transmission and analysis. By identifying and extracting key parameters (such as impact force, location, and critical environmental conditions) while filtering out redundant information, the system reduces data volume while maintaining information completeness for the essential measurements.
Solution Approach 2:
The data collection and processing approach applies different levels of detail to different types of data based on their importance. Critical data such as impact force and location are captured with high precision and transmitted in full detail, while less critical environmental data may be sampled at lower rates or with reduced precision, thereby managing data volume while preserving essential information quality.
Data Source
AI summary
Apparatus and methods of collecting and transmitting data of an object during an activity where object is impacted by another object. A method of tracking an object's location and trajectory based on data received at a portable device used by the participant; to determine a location and trajectory based on data received at a mobile device embedded in the object. Collection of data transmitted to a server, compiled by a computer program, and sent to a participant during the activity. When used in a stand-alone mode, environmental conditions, velocity, change in velocity, heading, spin, exact location, force imparted to the device and the estimated resting point of the device is delivered to the participant or spectator. When used in tandem with another similar device, additional performance data of velocity, change in velocity, spin and maximum force that can be imparted onto another object is provided to the participant or spectator.
