Domestic refrigeration appliance with an actuator for a container lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In household refrigeration appliances, especially no-frost models, foods requiring moisture to maintain nutritional value and structure dry out due to dehumidified air, necessitating separate containers for different humidity levels, but existing systems lack easy and complete control over humidity and air circulation.
Innovation Solution
A household refrigeration appliance with a heat-insulating inner container and a manually controllable refrigerated goods container lid, where a slide actuating means converts linear movement into lifting motion for opening and closing, featuring visual representations to indicate open or closed positions, allowing for direct and cost-effective coupling with minimal complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual actuating means with a slide is used to control the container lid, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The slide automatically provides visual feedback through the visual representation that changes with slide position, eliminating the need for separate indicators or complex control systems. The system serves itself by using the actuating mechanism's position to directly indicate the lid state.
Solution Approach 2:
The slide serves multiple functions: it acts as the manual actuating means to move the container lid and simultaneously provides visual indication of the lid position through the visual representation. This multi-functionality reduces the need for additional separate components.
2Ease of operation
If visual representations are added to indicate lid position, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The visual representation is merged with the slide structure itself, where the slide forms part of the visual indication system. This integration means the same component provides both mechanical actuation and visual feedback, avoiding additional separate indicator mechanisms.
Solution Approach 2:
The slide automatically provides visual feedback through the visual representation that changes with slide position, eliminating the need for separate indicators or complex control systems. The system serves itself by using the actuating mechanism's position to directly indicate the lid state.
3Object-affected harmful factors
If the refrigerated goods container is kept separate to maintain humidity, then the food quality is improved, but the ease of operation worsens due to reduced accessibility
Solution Approach 1:
The refrigerated goods container is segmented as a separate removable unit within the refrigerator, allowing it to be isolated for humidity control while still being easily accessible. The container can be pulled out independently from the main refrigerator body.
Solution Approach 2:
The container lid provides dynamic control over the opening, allowing selective access to the refrigerated goods. The lid can be opened to varying degrees or completely removed, providing flexible accessibility while maintaining the sealed environment when closed.
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
Enables easy, complete, and controllable opening of the refrigerated goods container, maintaining humidity levels and preventing food dryness, while providing a clear and intuitive operation through visual cues.
Implementation Method 1
a storage device, which is designed to convert a linear movement of the container lid executed by a manual actuating means in a depth direction into a lifting movement of the container lid for opening and closing the opening of the refrigerated goods container
