Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an effective method to provide timely and accurate feedback to batters to improve their swing timing and consistency in hitting baseballs, leading to missed opportunities and reduced performance in bat-and-ball sports.
Innovation Solution
A swing alert system utilizing sensors and alert units, such as cameras, RADAR, and haptic devices, to detect pitch characteristics and generate alerts for the batter to initiate a swing or stride at optimal times, synchronized with the ball's flight path, thereby enhancing timing and kinematics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional coaching methods are used to train batters, then batters can receive qualitative feedback, but the timing precision and objective measurement of swing events are insufficient
Solution Approach 1:
The system divides the swing event into discrete detectable components: stride start, swing start, and ball contact. Each event is detected independently by sensors placed on the batter's body and equipment, allowing precise timing measurement without requiring a complex monolithic system.
Solution Approach 2:
The sensor system serves multiple functions: detecting stride timing, swing timing, ball contact, and providing feedback. This multi-functionality reduces the need for separate devices for each measurement, thereby reducing overall system complexity while maintaining high measurement precision.
2Measurement precision
If multiple sensors are deployed to capture comprehensive swing data, then measurement accuracy improves, but system complexity and cost increase
Solution Approach 1:
Multiple sensors (accelerometers, gyroscopes, contact sensors) are merged into an integrated system that processes data collectively. The sensors are combined in a coordinated manner to detect swing events, reducing the complexity that would arise from managing separate independent measurement systems.
Solution Approach 2:
The system uses intermediary processing elements (microcontrollers, data fusion algorithms) that mediate between the raw sensor data and the final swing event detection. This intermediary layer simplifies the complexity by providing a structured method for integrating multiple sensor inputs into coherent swing event timing.
3Reliability
If real-time feedback is provided to batters during pitching, then swing timing can be improved, but information loss and delay in current systems remain problematic
Solution Approach 1:
The system implements real-time feedback by detecting swing events (stride start, swing start, ball contact) and providing immediate information to the batter and coach. This feedback loop ensures reliable timing information is communicated without loss, allowing batters to adjust their swing timing based on objective data.
Solution Approach 2:
The system performs preliminary detection and processing of swing events before final feedback is delivered. By pre-processing the sensor data and identifying swing events in advance, the system minimizes information loss and ensures timely, reliable feedback during the actual pitching sequence.

AI summary
A swing alert system disposed about a baseball setup that includes a pitcher and a batter, with one or more swing alert device that determine a speed and position of a ball along a flightpath of the ball pitched by the pitcher, the flightpath extending from the pitcher to a hitting location target proximate to the batter; determine a time when the ball will reach the hitting location target based at least in part on the determined speed and position of the ball along the flightpath; and generate a swing alert while the ball is traveling along the flightpath and before the ball reaches the hitting location target. The swing alert is generated at a time determined based at least in part on the determined time when the ball will reach the hitting location target and a defined swing time associated with the batter.
