Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying images in mirrors using LED displays are cumbersome due to spatial constraints, making it difficult to implement in spaces where the LED display cannot be placed.
Innovation Solution
A space production apparatus comprising a light source, viewing angle limiting surface, and mirror, which projects images onto the viewing angle limiting surface and reflects them through the mirror to create different visual information in real and mirror image spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an LED display is installed behind the mirror to display images, then images can be displayed in the mirror, but the system becomes heavy and difficult to implement due to spatial constraints
Solution Approach 1:
The patent extracts the image display function from the heavy LED display and implements it using a projector projecting images onto a semi-transparent film. This separates the display function from the mirror structure, eliminating the need for heavy LED displays while maintaining the image display capability in the mirror.
Solution Approach 2:
The patent introduces a semi-transparent film as an intermediary element between the projector and the mirror. This film allows projected images to be displayed while maintaining mirror reflectivity, serving as a mediator that enables image display without requiring heavy LED displays behind the mirror.
2Adaptability or versatility
If a heavy LED display is installed behind the mirror, then images can be displayed, but spatial constraints prevent implementation
Solution Approach 1:
The patent extracts the image display function from the heavy LED display and implements it using a projector projecting images onto a semi-transparent film. This separates the display function from the mirror structure, eliminating the need for heavy LED displays while maintaining the image display capability in the mirror.
Solution Approach 2:
The patent uses a projector to create optical copies of images on a semi-transparent film, which are then reflected by the mirror. This copying approach replaces the need for physical LED displays, making the system adaptable to spaces where heavy displays cannot be installed.
3Adaptability or versatility
If the same image is shown in both real space and mirror space, then the experience is predictable, but this lacks visual interest
Solution Approach 1:
The patent applies local quality by displaying different images in different spaces: the first image is projected onto the semi-transparent film for mirror space display, while the second image is displayed on a separate display device for real space viewing. This creates localized visual content tailored to each space, enhancing visual interest without requiring complex coordination between systems.

AI summary
A space production apparatus according to one aspect of the present invention includes a light source, a viewing angle limiting surface, and a mirror. The light source emits light for projecting a first image. The viewing angle limiting surface selectively reflects the light emitted from the light source toward a predetermined angular range, and is disposed such that an observer area where an observer is expected to be located is located in a direction outside the predetermined angular range. The first image is projected onto the viewing angle limiting surface. The mirror reflects the light emitted from the light source and reflected by the viewing angle limiting surface.
