Mirror with Vanishing Information via Selective Reflectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirror systems with integrated information displays are complex and costly to manufacture and maintain, posing challenges in providing a reliable and efficient method for displaying information that can vanish into the mirror.
Innovation Solution
A glass surface is configured with two regions of different reflectivity, where information is conveyed through the boundary between these regions, allowing the information to be visible when the system is in an 'ON' state and invisible when in an 'OFF' state, achieved by varying the reflectivity and using a light source behind the glass layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display is integrated within a mirror to show information, then information can be displayed to the user, but the system becomes complicated and expensive to manufacture and repair
Solution Approach 1:
The patent extracts the information display function from a separate display device and integrates it directly into the mirror structure. The mirror itself becomes the display medium through selectively reflective regions, eliminating the need for separate display components and reducing system complexity while maintaining information display capability
Solution Approach 2:
The mirror is designed to perform multiple functions: it serves as both a traditional reflective surface and an information display device. By incorporating selectively reflective regions that can be controlled to display information, the mirror becomes a multi-functional device that combines grooming and information delivery without requiring separate dedicated devices
2Loss of information
If a display is integrated within a mirror to show information, then information can be displayed to the user, but manufacturing and maintenance costs increase
Solution Approach 1:
The patent merges the display functionality with the mirror manufacturing process itself. The selectively reflective regions are integrated into the mirror structure during manufacturing, allowing information display capability to be built-in rather than added as a separate component, thereby reducing overall manufacturing costs
Solution Approach 2:
The patent uses the mirror's reflective surface as a copy or alternative to traditional display screens. Instead of using complex display technologies, the system creates visual information by selectively reflecting or absorbing light in different regions of the mirror, providing a cost-effective alternative to conventional display implementations
3Loss of information
If information is displayed in a mirror, then the user can see the information, but the information remains visible when not in use
Solution Approach 1:
The patent implements dynamic control of the mirror's reflective properties. The selectively reflective regions can change their reflectivity state based on control signals, allowing information to be displayed only when needed and to vanish when not in use. This dynamic behavior enables on-demand information display while maintaining the mirror's normal reflective function

AI summary
Apparatuses, methods, and systems are taught that convey information in a mirror to a user. A glass layer has a front side and a back side. The glass layer further includes a first region. The first region has a first optical property. A second region has a second optical property. The first optical property is different than the second optical property. A first boundary exists where the first region meets the second region and the first boundary is shaped to convey information when the second region is illuminated from the back side and the glass layer is viewed from the front side by the user. When the second region is not illuminated from the back side the first region and the second region provide substantially the same reflection when the glass layer is viewed from the front side by the user, and the first boundary does not convey information.
