Walking Heart Rate Reference for Physical Strength Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively evaluate physical strength in walking exercises due to the lack of a standardized method for heart rate analysis, as the relationship between heart rate and walking speed varies by age and gender, making it difficult to apply techniques developed for running to walking exercises.
Innovation Solution
A physical strength evaluation system that includes a reference storage for walking heart rate references, a speed acquisition unit, a heart rate acquisition unit, a standard value derivation unit, and a level determination unit to calculate a physical strength level based on the difference between measured and standard relative heart rates, allowing for accurate evaluation across different ages and genders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the relationship between heart rate and running speed is applied to walking exercise evaluation, then the evaluation method can be established, but the measurement precision deteriorates because the relationship does not always apply to walking and varies by age and gender
Solution Approach 1:
The patent segments the evaluation method by creating separate walking-specific heart rate reference tables for different age groups and genders, rather than using a unified running-based model. This segmentation allows each group to be evaluated according to its specific characteristics, improving measurement precision while maintaining ease of implementation through standardized tables.
Solution Approach 2:
The patent applies local quality by providing different heart rate reference standards for different populations (age groups and genders). Each population receives a customized reference table tailored to its specific physiological characteristics, ensuring that the evaluation method adapts to local variations in heart rate responses during walking exercise.
2Adaptability or versatility
If a standardized heart rate reference for walking is created, then the adaptability improves for different age and gender groups, but the device complexity increases due to multiple reference tables
Solution Approach 1:
The patent achieves universality by creating a comprehensive evaluation system that handles multiple age groups and genders through a unified interface. The system automatically selects and applies the appropriate reference table based on the subject's attributes, providing universal adaptability without requiring users to manually manage multiple complex reference standards.
Solution Approach 2:
The system implements self-service by automatically selecting the appropriate heart rate reference table based on the subject's age and gender inputs. The evaluation process autonomously retrieves and applies the correct standardized data without requiring manual intervention or complex user management of multiple reference tables, thereby reducing perceived device complexity.
3Ease of operation
If the amount of change in heart rate with respect to walking speed is used for evaluation, then the evaluation can be performed, but the reliability decreases because the tendency of heart rate varies by age and gender
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing standardized heart rate reference tables for various walking speeds, age groups, and genders before actual evaluation. This preliminary preparation ensures that reliable, pre-validated reference data is readily available during evaluation, eliminating the need for complex real-time calculations and ensuring consistent, reliable results across different subjects.

AI summary
In a physical strength evaluation system, a reference storage stores a walking heart rate reference in which a correspondence relationship of a standard value of a relative heart rate with respect to a walking speed is defined for every gender and every age, a speed acquisition unit acquires a measured value of a walking speed of a subject, a heart rate acquisition unit acquires a measured value of the relative heart rate of the subject. A standard value derivation unit derives the standard value of the relative heart rate corresponding to the measured value of the walking speed that has been acquired, based on the walking heart rate reference. A level determination unit determines an evaluation value of a physical strength level of the subject, based on a difference between the measured value of the relative heart rate and the standard value of the relative heart rate.
