Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement systems for trampoline competitions lack precision and automation in determining an athlete's flight time and horizontal movement, which are crucial for awarding points, as they rely on visual judgments and incomplete sensor arrangements.
Innovation Solution
A system comprising at least four independent motion sensor assemblies placed around the trampoline, each connected to a base station for precise and automatic data collection, using accelerometers, gyroscopes, and magnetometers to calculate flight time and position with high accuracy, and a computer for immediate point allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visual judgment by referees is used to determine horizontal displacement, then the device complexity is reduced, but the measurement precision deteriorates
Solution Approach 1:
The patent replaces the mechanical/visual judgment system with an automated sensor-based measurement system. Motion sensors and processing units automatically detect and calculate horizontal displacement, eliminating the need for visual judgment by referees and significantly improving measurement precision while maintaining manageable system complexity through modular sensor placement.
2Measurement precision
If automated sensor systems are implemented to measure flight time and position, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The measurement system is divided into multiple independent sensor units positioned at different locations around the trampoline. Each sensor unit independently measures specific parameters, and the processing unit integrates these segmented measurements to achieve high-precision flight time and position detection while keeping individual sensor components relatively simple.
3Measurement precision
If multiple sensor assemblies are deployed around the trampoline, then the measurement precision is improved, but the ease of operation deteriorates
Solution Approach 1:
Multiple sensor assemblies are merged into a unified measurement system with a central processing unit that automatically integrates data from all sensors. This combination allows the system to achieve high position measurement precision through coordinated multi-sensor input while simplifying operation, as the processing unit automatically handles data fusion and calculation without requiring manual intervention.
4Productivity
If automatic detection systems are used for point allocation, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The measurement system performs self-service by automatically calculating flight time, horizontal displacement, and point allocation based on sensor data, without requiring external referees or manual intervention. The processing unit autonomously processes measurement data and determines scores, significantly improving productivity while keeping the automation complexity manageable through straightforward measurement-to-score calculation logic.

AI summary
For the method and system (1) for measuring physical parameters, several motion sensor assemblies (2) are arranged in different positions on a trampoline (10) and activated to measure any movement over time during jumps performed by a competitor on the trampoline. Following processing of the measurements taken by each sensor assembly, data signals are transmitted to a base station (25). Based on the various measurements received over time from each sensor assembly, the base station determines the flight time of each jump by the competitor and the competitor's contact position on the trampoline mat (21) in order to award points to the competitor for completing a predetermined number of jumps during the competition.
