Solution Overview
Problem
Users face challenges with cleaning juicers for green vegetable juice due to residue accumulation, and the juice's freshness and nutrient preservation are compromised during storage due to varying ingredient shelf lives.
Innovation Solution
A smart system and method that calculates the freshness and remaining shelf life of stored green vegetable juice by selecting an indicator ingredient, using sensors to track weight and storage conditions, and displaying status information through a smart button on a user terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If green vegetable juice is extracted in advance and stored for multiple days, then users can avoid daily cleaning of the juicer, but the freshness and nutrient quality of the juice deteriorates due to varying ingredient shelf lives
Solution Approach 1:
The system performs preliminary actions by automatically tracking juice extraction dates, calculating remaining shelf life based on ingredient characteristics, and providing advance notifications before the juice expires. This allows users to plan consumption in advance without needing to repeatedly extract and store juice, thereby maintaining freshness while reducing cleaning frequency.
Solution Approach 2:
The system implements continuous feedback by monitoring storage duration, calculating real-time freshness status, and notifying users when juice approaches expiration. This feedback loop enables users to consume juice at optimal freshness points without over-storing, thus maintaining quality while minimizing cleaning cycles.
2Adaptability or versatility
If multiple ingredients with different shelf lives are used in green vegetable juice, then nutritional diversity is improved, but determining overall juice freshness becomes complex and inaccurate
Solution Approach 1:
The system applies local quality by assigning specific shelf life characteristics to each individual ingredient while maintaining a unified overall freshness assessment. Each ingredient's degradation rate is tracked separately based on its specific properties, then synthesized into a comprehensive juice freshness status, allowing nutritional diversity without proportional complexity increase.
Solution Approach 2:
The system introduces an intermediary computational layer that translates multiple ingredient shelf life parameters into a single unified freshness indicator. This intermediary processing layer manages the complexity of multi-ingredient tracking by aggregating individual ingredient data into an overall juice status that is simple for users to understand and act upon.
3Device complexity
If users manually track juice freshness and consumption, then system complexity is minimized, but users cannot intuitively monitor remaining shelf life and amount of stored juice
Solution Approach 1:
The system implements self-service by automatically tracking juice extraction dates, calculating remaining shelf life, monitoring storage duration, and providing real-time status updates without requiring manual user input. The system serves itself by managing all freshness and quantity information autonomously, then presenting this information intuitively to users through notifications and status displays.
Solution Approach 2:
The system provides continuous feedback to users about juice status including remaining shelf life, storage duration, and consumption recommendations. This feedback mechanism ensures users have complete awareness of juice conditions without manual tracking, while the automated nature of the feedback keeps system complexity low by using standard computational processes.

AI summary
Proposed is a smart method of providing information about green vegetable juice, the method including: obtaining juice-extraction information which includes information about juice-extraction time of the green vegetable juice, information about weight of the green vegetable juice, and information about ingredients for the green vegetable juice; receiving intake information about the green vegetable juice from a user; calculating change in the weight and freshness of stored green vegetable juice based on the juice-extraction information and the intake information; and generating and displaying a smart button with status information about the stored green vegetable juice based on the calculated change in the weight and freshness of the green vegetable juice. By this method, it is possible to intuitively know the weight and the freshness of the stored green vegetable juice.
