Refrigerator having panel assembly covering opening of outer plate of door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators do not allow users to visually inspect the interior while the door is closed, lacking transparency and efficient illumination, which can lead to difficulties in accessing contents and maintaining the storage environment.
Innovation Solution
A refrigerator design featuring a sub-door with a half-mirror panel assembly that can be made transparent by a user's operation, incorporating a knock detection device to activate lighting for uniform illumination of the interior, ensuring easy installation and maintenance, and minimizing gaps for improved insulation and wire management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a glass panel assembly is installed in the door to enable visibility, then transparency is improved, but insulation performance deteriorates due to potential gaps and exposure
Solution Approach 1:
The panel assembly is nested within a dedicated panel installation opening in the door structure. The outer plate contains a recessed area where the panel assembly is housed, creating a nested configuration that allows the panel to be integrated into the door while maintaining the door's overall structural integrity and insulation properties.
Solution Approach 2:
A cover plate is provided as a separate, replaceable component that can be easily installed and removed. The cover plate is configured to cover the panel assembly when not in use, providing insulation protection, and can be quickly replaced if damaged or worn, rather than requiring replacement of the entire door structure.
2Difficulty of detecting and measuring
If a detection device is exposed on the door surface to detect knocking operations, then detection capability is improved, but aesthetic appearance deteriorates due to exposed sensors
Solution Approach 1:
The cover plate serves as an intermediary element between the detection device and the external environment. It appears to be a simple cosmetic cover from the outside, maintaining aesthetic appearance, while actually functioning as a housing that protects and positions the knock detection device. The cover plate translates the need for detection into a form that does not compromise design.
Solution Approach 2:
The cover plate is designed with specific local features: it has a knock detection device disposed on its surface at a location corresponding to the panel assembly position, and includes a through-hole positioned to align with the panel assembly opening. This localized functionality allows detection capabilities to be integrated without compromising the overall aesthetic of the door surface.
3Ease of repair
If the panel assembly is made removable for maintenance, then ease of repair is improved, but structural integrity deteriorates due to additional openings and assembly complexity
Solution Approach 1:
The door structure is segmented into distinct functional modules: the outer plate with its installation opening, the panel assembly as a separate removable unit, and the cover plate as an independent protective element. This segmentation allows the panel assembly to be easily removed for maintenance while the outer plate and cover plate maintain the structural integrity of the door. Each component can be serviced independently without affecting the overall door strength.
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 users to see through the refrigerator door while closed, enhances operational recognition, prevents dew condensation, and maintains insulation and wire organization, providing a clear and well-lit interior for efficient storage and access.
Implementation Method 1
a panel assembly provided at the sub-door, and having a half-mirror structure which allows to selectively see through an inside of the opening part
Implementation Method 2
a door lighting unit provided above the panel assembly, turned on or off by the knock detection device to selectively illuminate an internal space of the opening part
Implementation Method 3
a knock detection device disposed at a rear surface of the panel assembly, and configured to detect a user' knocking operation on the panel assembly
