Dynamic Body Weight Target Adjustment via Achievement Rate Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body weight management devices do not account for the actual pace of weight loss, making it difficult for users to achieve targets during irregular daily routines, leading to motivation issues.
Innovation Solution
A body weight management device that calculates a new intra-day target weight loss value based on the past target achievement rate, adjusting the target according to the user's past performance to better align with their weight loss pace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed daily weight loss targets are set without considering actual achievement rate, then targets are clear and measurable, but users cannot achieve targets during irregular routines leading to demotivation
Solution Approach 1:
The patent applies dynamics by making the weight loss target adjustable rather than fixed. The target value is dynamically modified based on the user's achievement rate over a predetermined period. When the achievement rate falls below a threshold, the system increases the target value to make it more attainable, thereby maintaining user motivation and consistent target achievement across varying routine conditions.
Solution Approach 2:
The patent implements feedback by continuously monitoring the user's weight loss achievement rate and using this information to adjust future targets. The system calculates the ratio of actual weight loss to target weight loss over a predetermined period, and this feedback loop enables the target value to be adaptively modified, ensuring targets remain challenging yet achievable despite irregular routines.
2Adaptability or versatility
If weight loss targets are adjusted to be easier to achieve, then user motivation is maintained, but the target may become too lenient and lose its guiding value
Solution Approach 1:
The system dynamically adjusts target stringency based on performance data. Rather than using a fixed target, the patent modifies the target value proportionally when achievement rates fall below thresholds, maintaining an appropriate balance between flexibility and precision. This ensures targets remain guiding yet adaptable to individual user circumstances.
3Ease of operation
If daily routines are irregular, then user flexibility is improved, but achieving fixed weight loss targets becomes difficult
Solution Approach 1:
The patent resolves this contradiction by making the target value dynamic rather than fixed. The system accommodates irregular routines by adjusting targets based on actual performance, allowing users flexibility in their daily schedules while maintaining reliable target achievement through adaptive goal setting.
Solution Approach 2:
The system uses feedback from actual weight loss performance to adjust targets, creating a responsive system that adapts to irregular routines. By monitoring achievement rates and modifying targets accordingly, the system maintains reliability in target achievement regardless of routine variability.

AI summary
A body weight management device includes: a change obtainment unit for obtaining an intra-day body weight change value on a daily basis based body weight measurement values of a measurement subject measured on a daily basis; an achievement rate obtainment unit for comparing the intra-day body weight change value obtained by the change obtainment unit with an intra-day target weight loss value and obtaining, based on a result of the comparison, a target achievement rate indicating a percentage of total days in a predetermined period in which the intra-day body weight change value has reached the intra-day target weight loss value; and a target obtainment unit for obtaining, based on the target achievement rate obtained by the achievement rate obtainment unit, a new intra-day target weight loss value to serve as a target for future body weight measurement.
