Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current personal fitness devices do not effectively track weightlifting activities, such as the amount of weight lifted and number of repetitions, which are crucial for users who engage in weightlifting exercises.
Innovation Solution
A wireless hand sensory apparatus, including sensor-based gloves with force sensors and a tracking system that determines the weight of items by registering force and motion, providing feedback on lifting technique and correlating repetitive motions with exercises, and synchronizing data between gloves for weight distribution analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional personal fitness devices are used, then heart rate and step count can be tracked, but weightlifting activities including weight amount and repetitions cannot be tracked
Solution Approach 1:
The wearable device integrates multiple sensor types (force sensors, motion sensors, accelerometers) and processing capabilities into a single system that can track both traditional fitness metrics (heart rate, steps) and weightlifting-specific data (weight amount, repetitions, exercise type), making the device universally applicable to diverse fitness activities
Solution Approach 2:
The system uses force sensors as intermediaries to detect the weight being lifted through hand-glove contact, and motion sensors as intermediaries to detect movement patterns, translating physical actions into digital data that identifies exercise type and parameters
2Measurement precision
If force sensors are integrated in hand gloves, then weight and motion can be detected, but device complexity increases
Solution Approach 1:
The force sensing capability is segmented and distributed across multiple sensors positioned at different locations within the hand glove (e.g., palm, fingers), allowing the system to detect various aspects of force application and weight distribution through modular sensor elements
Solution Approach 2:
The system merges force sensor data with motion sensor data and processor analysis in an integrated tracking system, combining multiple measurement approaches to achieve accurate weight and exercise identification while managing complexity through unified processing
3Loss of information
If tracking system analyzes force and motion data, then exercise identification and feedback can be provided, but processing requirements increase
Solution Approach 1:
The system performs preliminary processing by pre-defining exercise patterns and thresholds in the processor, allowing real-time identification of exercises through pattern matching against pre-established models rather than analyzing every motion from scratch
Solution Approach 2:
The tracking system automatically processes and interprets sensor data to identify exercises and provide feedback without requiring manual input or external analysis, with the processor autonomously analyzing force and motion patterns to generate exercise identification and guidance
