External detection see-through door and external detection see-through cabinet having same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage boxes with opaque doors are inconvenient as they require opening to check the internal condition, and opaque doors for security purposes make it difficult to assess who or what is on the other side without opening the door.
Innovation Solution
An external detection see-through door equipped with a transmission window, a sensor to detect specific external conditions, a light emitting module to increase internal light reflection, and an optical film that prevents visibility until the condition is detected, allowing the door to become see-through when a specific external condition is met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an opaque door is used to block sunlight or improve aesthetics, then security and privacy are improved, but the ability to check internal conditions without opening the door deteriorates
Solution Approach 1:
The door's optical properties are made dynamic through the use of an optical film that can switch between opaque and see-through states. When a sensor detects a specific external condition (such as a person approaching), the light emitting module activates and the optical film transitions to allow light transmission, enabling the door to adapt its transparency based on external conditions rather than being statically opaque or transparent
Solution Approach 2:
The optical film undergoes a change in its optical properties (from opaque to see-through) in response to light emission. This change in optical state allows the door to transition between blocking and transmitting light, effectively using optical property changes to resolve the contradiction between security and convenience
2Ease of operation
If a transmission window is made fully transparent to allow viewing, then the ability to check internal conditions is improved, but security and privacy deteriorate
Solution Approach 1:
The transmission window's transparency is made dynamic through the optical film that switches between opaque and see-through states based on sensor detection. The window is opaque during normal conditions to maintain security, and only becomes see-through when a specific external condition is detected, allowing the system to adapt to different security requirements
Solution Approach 2:
The door system automatically detects external conditions through the sensor and autonomously transitions between opaque and see-through states without requiring manual intervention. The system serves itself by detecting when viewing is needed and automatically activating the light emitting module and optical film transition
3Illumination intensity
If the optical film has high light transmittance to allow see-through, then visibility is improved, but the ability to block light when not detected deteriorates
Solution Approach 1:
The optical film's light transmittance is made dynamic, switching between high transmittance (see-through) and low transmittance (opaque) states. The film maintains high light blocking capability during normal conditions and only transitions to high visibility state when the sensor detects a specific external condition, allowing the system to provide both functions at different times
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 convenient checking of internal objects without opening the door by becoming transparent when a specific condition, such as a person approaching or lighting change, is detected, improving usability and security.
Implementation Method 1
an optical film that is provided on the transmission window and has a light transmittance that prevents the cabinet from being see-through from the outside before the sensor detects the specific condition
Implementation Method 2
a light emitting module configured to increase an amount of emitted light according to a signal from the sensor

AI summary
One embodiment of the present disclosure provides an external detection see-through door of a cabinet that stores objects. The external detection see-through door includes a transmission window, a sensor configured to detect a specific external condition in front of the transmission window, a light emitting module configured to increase an amount of emitted light according to a signal from the sensor, which has detected the specific external condition, to increase an amount of light that is reflected from inside the cabinet and heads toward the transmission window, and an optical film that is provided on the transmission window and has a light transmittance that prevents the cabinet from being see-through from the outside before the sensor detects the specific condition and allows the cabinet to be see-through from the outside due to light that is reflected from inside the cabinet and transmitted through the transmission window and the optical film due to the light emitting module increasing the amount of emitted light according to the signal from the sensor that has detected the specific external condition.
