Body Composition Monitor Variable Display Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional body composition monitors display changes in body composition components uniformly, making it difficult for users to visualize initial changes, which can lead to reduced motivation for weight reduction or increase efforts.
Innovation Solution
A body composition monitor that adjusts display widths based on the magnitude of body composition component changes, using differentiated determination widths to highlight small changes more prominently and vary display sizes according to the nature of changes, incorporating both bioelectrical impedance and body weight changes for a more accurate evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If equal display widths are used for all body composition component changes, then the display structure is simple and uniform, but small initial changes are not obviously shown and user motivation decreases
Solution Approach 1:
The patent applies local quality by assigning different display widths to different stages of body composition change. Specifically, the first stage (small changes) uses a narrower display width, while the second stage (large changes) uses a wider display width. This allows the display to optimize visibility for each specific range of change, making small initial changes clearly visible without requiring a completely complex variable width system.
Solution Approach 2:
The patent changes the display width parameter based on the magnitude of body composition change. By defining multiple stages with different determination widths, the system dynamically adjusts the display width parameter according to the measured change amount, thereby improving the visibility of small changes while maintaining a relatively simple structured approach.
2Ease of operation
If differentiated determination widths are used for different stages, then small changes can be displayed prominently to increase user motivation, but the display system becomes more complex
Solution Approach 1:
The patent applies local quality by assigning different determination widths to different stages of body composition change. The first stage uses a smaller determination width to make small changes visible, while the second stage uses a larger determination width for large changes. This localized differentiation improves user motivation by making progress visible at each stage without requiring complex variable width adjustments throughout the entire system.
Solution Approach 2:
The patent segments the body composition change range into multiple stages, with each stage having its own determination width. This segmentation allows the system to handle different magnitudes of change with appropriate display widths, improving ease of operation and user motivation while keeping the overall structure manageable through clear stage definitions.
3Measurement precision
If only bioelectrical impedance is used for body composition measurement, then the measurement process is simple, but the evaluation accuracy is insufficient
Solution Approach 1:
The patent merges bioelectrical impedance measurement with body weight measurement to improve body composition evaluation accuracy. By combining these two measurement methods, the system can calculate body composition changes more accurately, accounting for both impedance-based composition data and weight-based validation, without requiring a completely complex new measurement system.
Solution Approach 2:
The patent makes the body composition monitor multi-functional by incorporating both bioelectrical impedance measurement and body weight measurement capabilities. This allows the single device to perform multiple measurement functions, improving evaluation accuracy through cross-validation of data while maintaining a relatively simple integrated device structure.
