Refrigerator Camera Housing for Leak-Proof Imaging and Wireless Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera devices installed in storage units, such as refrigerators, face challenges in capturing effective images due to the harsh environment, which affects their performance and reliability.
Innovation Solution
A camera device with a waterproof and explosion-proof design, featuring a wide-angle lens and a communication module configured to transmit images externally, is installed inside the storage unit, utilizing a non-metallic case and strategic placement of components to minimize interference with wireless communication and ensure reliable image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera device is installed inside a storage unit, then image capture capability is provided, but the device is exposed to harmful factors such as liquids and refrigerant leaks
Solution Approach 1:
The camera device is segmented into a sealed camera housing that encapsulates the image capturing element, separating it from the harsh storage environment. The housing acts as a protective barrier while the camera continues to capture images through a designated window or opening.
Solution Approach 2:
A communication module serves as an intermediary between the camera device and external systems, enabling image transmission without requiring direct exposure or connection to external components that could be vulnerable to the storage environment.
2Strength
If a metallic case is used for the camera device, then structural strength is provided, but wireless communication is interfered with
Solution Approach 1:
The camera housing uses composite or non-metallic materials that provide sufficient structural strength while being transparent or permeable to wireless signals. This allows the housing to protect internal components while maintaining communication reliability.
Solution Approach 2:
The communication module is extracted and positioned separately from the main camera housing, allowing it to operate outside the potentially interfering metallic structure while still being part of the integrated camera device system.
3Ease of operation
If the image capturing element is exposed to the storage environment, then direct image capture is enabled, but the device reliability decreases due to harsh conditions
Solution Approach 1:
The image capturing element is protected beforehand by enclosing it in a sealed housing that shields against liquids, refrigerant, and other harsh environmental factors. This protective structure is designed in advance to prevent damage while allowing the camera to function.

AI summary
A camera device for use in a storage unit includes a case configured to be detachably installable inside the storage unit to a holder unit configured to hold the case inside the storage unit, an image capturing element provided inside the case and configured to capture an image inside the storage unit where the case is installed, an image capture window provided on a first surface portion of the case and configured for capturing the image inside the storage unit by the image capturing element, and a preventing element configured to prevent the case from being attached to the holder unit in an orientation other than a predetermined orientation. The image capture window is configured for capturing image inside the storage unit by the image capturing element. The holder unit holds the case inside the storage unit. The image capturing element captures the image inside the storage unit with the case being installed in the predetermined orientation.
