Body Fat Measurement Device Using Personalized Reference Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional body fat measurement devices provide users with numerical values only, making it difficult to determine normal or obese status, and rely on standardized databases that do not account for individual preferences, particularly among teenage girls who have unique body shape ideals.
Innovation Solution
A body fat measurement device and method that compares local body fat for each body part of a user with a selected individual's body fat, allowing users to choose a particular person for comparison, and providing results through a user interface, using a database of body fat information for various body parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If body fat measurement results are provided as numerical values only, then the measurement process is simple, but users cannot determine whether their body fat status is normal or obese
Solution Approach 1:
The patent introduces a reference database as an intermediary between the measurement device and the user. The device compares the user's body fat measurement with reference values from the database (which are pre-classified by age, race, and gender) to determine whether the user is normal or obese. This mediator provides interpretability without requiring complex processing at the user end.
2Adaptability or versatility
If a standardized database is used for comparison, then the measurement method is simple to implement, but it does not account for individual preferences and body shape ideals
Solution Approach 1:
The patent makes the reference database dynamic and user-configurable. Users can select their own reference persons (models) whose body shapes they wish to emulate, and the system allows customization of reference values by body part (bust, waist, hips, thighs, legs). This dynamic adaptation enables personalization while maintaining systematic organization through the database structure.
3Reliability
If body fat measurements are taken from a large number of people to build a credible database, then the reference data becomes more reliable, but it takes a great amount of time and cost
Solution Approach 1:
The patent performs the time-consuming database building action in advance, before the actual body fat measurement takes place. A comprehensive reference database is pre-built by collecting body fat data from many people, classifying it by age, race, and gender, and establishing reference ranges. This preliminary action ensures reliability while making the actual measurement process quick and convenient for users.
Data Source
AI summary
A body fat measurement result providing method includes maintaining a body fat information database having stored therein at least one particular person's body fat information, which includes local body fat information for at least one body part of the at least one particular person, providing a user with a particular person list including the at least one particular person, and receiving a selection from the user of a first particular person selected from the particular person list, and generating a measurement result information by comparing the user's local body fat measured for at least one body part of the user, with corresponding local body fat information for the at least one body part of the first particular person.
