Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stress estimation devices and methods fail to accurately identify the stressors leading to chronic stress, as they do not provide specific techniques for determining the causes of chronic stress.
Innovation Solution
A stressor estimation device and method that acquire chronic stress values in different periods, calculate difference information between these values and associated events, and estimate stressors based on this information to accurately identify chronic stress causes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing stress estimation devices are used, then stress measurement is possible, but the ability to identify specific stressors leading to chronic stress is insufficient
Solution Approach 1:
The patent segments the stress measurement process into multiple components: acquiring chronic stress values at different time points, identifying stressors associated with each time point, calculating differences between time points, and determining stressor changes. This segmentation allows precise identification of which stressors contribute to chronic stress by isolating and analyzing each component separately.
Solution Approach 2:
The patent performs preliminary actions by acquiring chronic stress values and identifying stressors at multiple different time points before finally determining the stressor changes. This preliminary data collection at various time points enables subsequent analysis to accurately identify which stressors lead to chronic stress, rather than attempting to identify causes after the fact.
2Measurement precision
If stress values are measured at multiple time points, then stressor identification accuracy improves, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional system that performs multiple tasks: acquiring chronic stress values at different time points, identifying stressors at each time point, calculating differences between time points, and determining stressor changes. By making the system multi-functional, the patent achieves accurate stressor identification without requiring separate specialized devices for each function.
Solution Approach 2:
The patent uses feedback mechanisms by comparing chronic stress values at different time points and using this feedback to identify stressor changes. The system continuously monitors stress values, identifies stressors, calculates differences, and determines which stressors lead to chronic stress, creating a feedback loop that improves measurement accuracy while managing system complexity through iterative processing.

AI summary
A stressor estimation device 1X mainly includes a chronic stress acquisition means 16X, a difference acquisition means 17X, and a stressor estimation means 18X. The chronic stress acquisition means 16X acquires a first chronic stress value of a target person in a first period and a second chronic stress value of the target person in a second period. The difference acquisition means 17X acquires difference information representing a difference between the first chronic stress value and the second chronic stress value and a difference between an event that occurred in the first period and an event that occurred in the second period. The stressor estimation means 18X estimates a stressor relating to a chronic stress of the target person, based on the difference information.
