Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional body composition monitors fail to effectively identify biases in body composition coverage across different body sites, such as fat and muscle distribution, limiting user awareness and targeted exercise strategies.
Innovation Solution
A body composition monitor equipped with electrodes for whole-body and site-specific measurements, calculating site ratios and evaluation indices, and displaying these results on a user interface with schematic human body markings to highlight areas of high or low composition relative to averages, along with age and physical attribute-based comparisons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional body composition monitors calculate and display various indices from body composition, then the user can recognize their position from displayed information, but whether there is bias in covering for every site of the body composition cannot be recognized
Solution Approach 1:
The patent divides body composition analysis into site-specific segments (upper limb, lower limb, trunk) and calculates composition values for each segment separately. This segmentation enables the system to identify biases in covering for every site by comparing site-specific composition values against reference data, thereby resolving the information loss problem without requiring excessive system complexity.
2Measurement precision
If site-specific body composition values are calculated, then detailed distribution information is obtained, but the ability to identify biases in covering across sites is limited
Solution Approach 1:
The patent implements a feedback mechanism by comparing site-specific body composition values with reference data stored in the system. This comparison provides feedback that enables the identification of biases in covering across different body sites, thereby maintaining measurement precision while eliminating information loss regarding bias identification.
3Ease of operation
If only whole body body composition is measured, then measurement simplicity is maintained, but site-specific bias information is lost
Solution Approach 1:
The patent segments the body into multiple measurement zones (upper limb, lower limb, trunk) and calculates body composition values for each segment. This segmentation approach maintains ease of operation by using a single measurement process while capturing site-specific composition information, thereby preventing information loss without complicating the measurement procedure.

AI summary
A body composition monitor calculates a body composition value of a whole body and a body composition value by site of a user using a plurality of electrodes, and calculates a site ratio representing a ratio of the body composition value by site with respect to the body composition value of the whole body. A process of outputting ratio information (site ratio and/or evaluation index of site ratio) related to the calculate site ratio is then carried out.
