Keep-Fresh Container as Outer Wall for Direct-Access Humidity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing domestic refrigeration appliances require multiple actions and the opening of a separate door to access the keep-fresh container, which complicates the process of setting and maintaining different humidity levels for food storage, leading to inconvenient handling and potential loss of humidity.
Innovation Solution
A domestic refrigeration appliance design where the keep-fresh container, capable of maintaining a different humidity level than the main compartment, is integrated as a drawer with a front wall forming an outer wall, allowing direct access without opening a separate door, featuring a setting element on the side wall for humidity control and a carrier tray for stability, enabling ergonomic and unrestricted access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the keep-fresh container is completely arranged in the interior compartment with a separate door, then the humidity level can be maintained independently, but the access to the container becomes complex requiring multiple actions
Solution Approach 1:
The patent merges the keep-fresh container with the exterior of the refrigeration appliance by making the front wall of the container form an outer wall of the appliance. This integration allows the container to be accessed directly from the outside without requiring opening of a separate door, while still maintaining its independent humidity control capability through the humidification apparatus and control element.
2Adaptability or versatility
If a separate door is provided for the keep-fresh container, then humidity can be controlled independently, but the device complexity increases
Solution Approach 1:
The patent eliminates the separate door structure by integrating the keep-fresh container's front wall with the appliance's outer wall. The container is positioned such that it can be accessed directly from the exterior, removing the need for an additional door mechanism while preserving the independent humidity control functionality through the humidification apparatus.
3Reliability
If the keep-fresh container is accessible only through the interior compartment door, then humidity is protected, but the handling efficiency decreases
Solution Approach 1:
The patent combines the keep-fresh container with the appliance's exterior structure, allowing users to access the container directly without first opening the interior compartment door. This integration significantly improves handling efficiency by reducing the number of actions required, while the container's design with a closable cover maintains humidity protection when not in use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies access to the keep-fresh container, allowing easy insertion and removal of foodstuffs, maintains humidity levels independently, and prevents unwanted humidity loss, enhancing user convenience and handling efficiency.
Implementation Method 1
a humidification apparatus in the domestic refrigeration appliance, which generates humidity and controls the introduction of the humidity into the keep-fresh container
