Vegetable Preservation Case with Nutrient Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current refrigerator freezing technologies only slow down the decay of vegetables, providing a short-term solution for preservation, and there is a need for a method to maintain vegetables in a stagnant or slow-growing state for longer periods after they are picked and sold.
Innovation Solution
A vegetable preservation and growing case with a thermal insulation body, electric control component, and pipeline system that circulates a nutrient solution, allowing continuous nutrient absorption and maintaining a controlled growing environment, including adjustable lighting and humidity, to keep vegetables in a slow-growing or stagnant state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If refrigerator freezing technologies are used for vegetable preservation, then the decay of vegetables is slowed down, but the preservation time is very short
Solution Approach 1:
The patent changes the preservation parameters from freezing conditions to controlled temperature and humidity conditions with nutrient supply. The thermal insulation case body maintains a specific temperature range that prevents freezing while slowing decay, and the pipeline component continuously supplies nutrient solution to keep vegetables in a stagnant growth state, thereby extending preservation time from hours to days or weeks
Solution Approach 2:
The patent implements a self-service preservation system where the pipeline component automatically circulates nutrient solution to the vegetables, and the thermal insulation case body automatically maintains the required temperature and humidity conditions. This continuous self-maintenance of optimal preservation conditions eliminates the need for manual intervention and enables long-term preservation without frequent human intervention
2Duration of action of moving object
If a thermal insulation case body with pipeline component is used to circulate nutrient solution, then vegetables can be preserved for long time in a stagnant growth state, but the device structure becomes more complex
Solution Approach 1:
The pipeline component serves multiple functions: it supplies nutrient solution to vegetables, removes excess water, and can be integrated with the thermal insulation case body structure. The thermal insulation case body simultaneously provides thermal insulation, structural support, and containment for the nutrient solution circulation system. This multi-functionality reduces the need for separate components and simplifies the overall device structure while achieving long-term preservation
