Meal Advice System Using Pre-Post Biological Data Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meal advice systems are limited in providing accurate advice as they rely on camera imaging and cannot function without a ceiling-mounted camera, leading to inaccurate analysis of meal-related biological data fluctuations and inappropriate advice.
Innovation Solution
A meal advice provision system that includes a portable biological information measurement apparatus and an analysis apparatus capable of measuring and analyzing pre-meal and post-meal biological information, providing meal-related advice based on changes in carbohydrate indexes, regardless of the location, using wireless communication and a smartphone application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a ceiling-mounted camera is used to capture meal images for analysis, then meal record information can be automatically obtained, but the system cannot function at locations without such a camera
Solution Approach 1:
The patent introduces a portable biological information measurement apparatus as an intermediary device that can be carried by users to various locations. This apparatus measures biological information (such as blood glucose levels) and transmits it wirelessly to the analysis apparatus, serving as a mediator that enables meal advice provision without requiring ceiling-mounted cameras at dining locations.
Solution Approach 2:
The analysis apparatus is designed with multi-functionality, capable of receiving both image data from cameras when available and biological information data from portable measurement apparatus. This universal reception capability allows the system to function effectively in different environments - whether ceiling cameras are present or not - by adapting to the available data source.
2Reliability
If only image data is used for meal analysis, then visual record of meals is obtained, but clear causal relationships between meals and biological data fluctuations cannot be established
Solution Approach 1:
The patent merges multiple data types - image data from meal photography and biological information from portable measurement devices - into a unified analysis framework. By combining these different data sources and analyzing them together, the system establishes clearer causal relationships between meal consumption and subsequent biological responses, while maintaining comprehensive data utilization.
3Ease of operation
If ceiling-mounted cameras are installed for meal monitoring, then automated meal analysis is enabled, but device complexity and installation requirements increase
Solution Approach 1:
The patent segments the meal monitoring function into two independent components: the portable biological information measurement apparatus that users carry themselves, and the analysis apparatus that processes data. This segmentation eliminates the need for complex ceiling-mounted camera installations, as each component is self-contained and can be deployed independently without infrastructure requirements.

AI summary
A biological information analysis unit 22 that analyzes a change between pre-meal and post-meal biological information on the basis of pre-meal and post-meal biological information measured by a biological information measurement apparatus 100 and measurement times at which the pre-meal and post-meal biological information were obtained, and an advice provision unit 23 that provides meal-related advice on the basis of analysis results thereof are provided. As a result, it is possible to provide meal-related advice without a captured image of the meal. Additionally, by analyzing using the pre-meal and post-meal biological information, a causal relationship between the meal and the fluctuation between the pre-meal and post-meal biological information can be clarified and a user can be provided with appropriate meal advice based on the analysis results of the fluctuation in the biological information when eating at any location, not only at special locations where a camera is installed on the ceiling.
