Solution Overview
Problem
Current methods for disseminating training instructions to remote trainees and standardizing performance data across different locations lack efficiency and objectivity, and fail to accurately represent trainees' performance capabilities.
Innovation Solution
A handheld tae kwon do paddle equipped with a data port for loading digital workout performance templates, featuring separate user interfaces for trainers and trainees, utilizing Bluetooth, NFC, USB, Ethernet, or Wi-Fi for data transfer, and incorporating accelerometers and altimeters to timestamp performance data, along with a computerized system for storing and comparing performance data and displaying leaderboards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual training methods are used, then training flexibility is maintained, but training standardization and objective comparison across locations deteriorates
Solution Approach 1:
The patent uses digital copies of standardized performance templates that can be replicated across multiple locations. Each template contains precise performance criteria that can be consistently applied, allowing objective comparison of trainee performance across different training centers without requiring complex real-time communication systems between locations.
Solution Approach 2:
The training system is segmented into independent modular components: handheld targets with embedded processors, separate trainer and trainee user interfaces, and centralized performance templates. This segmentation allows each component to function independently while maintaining overall standardization, reducing the complexity burden on any single element.
2Adaptability or versatility
If remote training instruction is provided, then training accessibility improves, but instruction delivery efficiency deteriorates
Solution Approach 1:
The handheld target automatically executes pre-programmed training sequences without requiring real-time trainer intervention. The device self-manages the training flow by displaying instructions to the trainee, capturing performance data, and comparing results against standardized templates, thereby maintaining high instruction delivery efficiency while enabling remote accessibility.
Solution Approach 2:
Training instructions and performance evaluation criteria are prepared in advance as digital templates before the training session. This preliminary preparation allows the system to deliver structured instructions efficiently during remote training without requiring real-time decision-making or complex communication protocols between trainer and trainee.
3Quantity of substance
If performance data is collected from multiple locations, then training coverage expands, but data comparability deteriorates
Solution Approach 1:
The system standardizes performance measurement parameters across all locations by using a common set of evaluation criteria defined in the digital templates. Physical parameters such as strike force, accuracy, and speed are measured using the same units and thresholds regardless of location, ensuring data comparability while expanding training coverage to multiple sites.
Solution Approach 2:
The handheld target device serves multiple functions: it displays training instructions, captures performance data, compares results against standardized criteria, and communicates with both trainer and trainee. This multi-functionality consolidates data collection into a single universal system that maintains comparability across all training locations without requiring location-specific measurement systems.
