Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual observation and time recording are used to track speed ladder performance, then the method is simple and requires minimal equipment, but the measurement precision and reliability of performance data are low due to human subjectivity
Solution Approach 1:
The patent replaces manual observation and time recording (mechanical/human system) with an automated electronic system comprising sensors, processors, and display devices. Sensors attached to the speed ladder and/or user's footwear automatically detect foot movements, while processors analyze the data and provide immediate feedback through visual and auditory signals, eliminating human subjectivity and significantly improving measurement precision.
Solution Approach 2:
The system enables self-service by having sensors automatically attached to the speed ladder or user's footwear, which then autonomously detect, record, and analyze foot movement data without requiring manual intervention. The system self-regulates by providing real-time feedback through lights and sounds, allowing users to independently track and improve their performance.
2Loss of information
If detailed electronic tracking and analysis systems are implemented, then measurement precision and feedback quality improve, but the device complexity and cost increase significantly
Solution Approach 1:
The patent segments the tracking system into distinct functional components: sensors for data collection, processors for data analysis, and display devices for feedback delivery. This segmentation allows each component to perform its specific function efficiently, reducing overall system complexity while maintaining comprehensive data collection and analysis capabilities.
Solution Approach 2:
The system achieves multi-functionality by integrating multiple capabilities into a single unified platform that can detect various foot movement parameters, analyze performance data, provide real-time visual feedback through lights, provide auditory feedback, and track progress over time. This universal approach reduces the need for multiple separate devices and systems.
3Productivity
If automated sensor-based tracking is used, then productivity and data collection speed improve, but the ease of operation decreases due to setup and calibration requirements
Solution Approach 1:
The system employs self-service mechanisms where sensors automatically attach to the speed ladder or user's footwear and begin collecting data without manual configuration. The processors automatically calibrate and analyze the data streams, and the system self-adjusts based on detected movements, eliminating the need for complex setup and calibration procedures while maintaining high data collection efficiency.
Solution Approach 2:
The system provides continuous real-time feedback through visual lights and auditory signals that guide users on proper form and technique. This feedback mechanism allows users to self-correct during exercise, reducing the need for operator intervention and simplifying operation while maintaining high productivity through automated tracking.
