Solution Overview
Problem
Existing refrigerator and freezer designs for storing fruit and vegetables face challenges in maintaining optimal humidity and minimizing condensation, as the structure that prevents condensation in one device may not be effective in another due to varying cool air currents and fan performance.
Innovation Solution
The design incorporates at least two differently dimensioned openings in the container wall, which can be adjusted by using inserts or closure elements with pore structures, allowing for adaptation to different device conditions to ensure optimal storage conditions and gas composition control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a specific opening structure is used to prevent condensation in one device, then condensation is minimized in that device, but the same structure causes condensation in another device with different air flow conditions
Solution Approach 1:
The opening structure is designed to be dynamically adjustable through closure elements that can be positioned in different states (open, closed, partially closed). This allows the opening configuration to adapt to different air flow conditions in various refrigerator devices, resolving the contradiction between preventing condensation and maintaining versatility across different device types
Solution Approach 2:
The closure elements can change the effective opening parameters (size, shape, permeability) by being positioned in different configurations. This parameter adjustment capability allows the same container to optimize moisture removal for different device air flow conditions, preventing condensation while maintaining adaptability
2Adaptability or versatility
If multiple differently dimensioned openings are provided, then adaptability to different device conditions is improved, but device complexity increases
Solution Approach 1:
Multiple openings of different dimensions are integrated into a single container design that serves multiple functions: moisture removal, gas composition control, and adaptation to different device types. The closure elements provide universal adjustability across all openings, allowing one container design to serve various refrigerator configurations without requiring multiple specialized container types
Solution Approach 2:
The container wall is segmented into multiple discrete openings that can be independently controlled by individual closure elements. This segmentation allows selective adjustment of different openings based on specific device conditions, providing adaptability while maintaining a relatively simple overall container structure
