Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices lack the ability to accurately and personally tailor the tracking of exercise movements based on designated motions, leading to inconsistencies in counting the number of times these motions are performed.
Innovation Solution
A wearable device equipped with sensors and a processor that identifies exercise start, obtains motion data, and uses threshold values to count designated motions, allowing for personalized adjustment of these values based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed threshold values are used for counting exercise motions, then the device complexity is reduced, but the measurement precision of motion counting deteriorates
Solution Approach 1:
The patent implements dynamic threshold values that automatically adjust based on user-specific parameters such as height, weight, and body type. The system transitions from static, fixed thresholds to dynamic, adaptive thresholds that change according to individual user characteristics, thereby improving motion counting accuracy without significantly increasing device complexity.
Solution Approach 2:
The system changes the threshold parameter based on user input data including height, weight, and body type. By modifying the threshold values according to these physical parameters, the system achieves personalized motion counting that accurately reflects each user's specific exercise movements, resolving the contradiction between simple fixed thresholds and precise customized counting.
2Ease of operation
If generic motion tracking is implemented, then the ease of operation is improved, but the adaptability to different users deteriorates
Solution Approach 1:
The system enables users to input their own physical characteristics (height, weight, body type) and automatically generates personalized threshold values. This self-service approach allows users to customize their exercise tracking experience without requiring complex setup procedures or technical knowledge, maintaining ease of operation while achieving high adaptability to individual users.
Solution Approach 2:
The system collects user-specific physical parameters in advance before beginning motion tracking. By performing this preliminary data collection and processing, the system prepares personalized thresholds ahead of time, ensuring that the tracking is both easy to operate and highly adapted to each user's specific characteristics from the start.
3Manufacturing precision
If standardized threshold values are used for all users, then the manufacturing precision of the system is improved, but the reliability of motion counting for individual users deteriorates
Solution Approach 1:
The patent applies the principle of local quality by implementing user-specific threshold values tailored to each individual's physical characteristics. Instead of applying a uniform standardization approach, the system creates localized, personalized parameters for each user based on their height, weight, and body type, thereby improving reliability of motion counting for each user while maintaining systematic processing through automated calculations.
