Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic display devices are unsuitable for certain locations, such as windows and mirrors, due to their size and aesthetic impact, which obstructs views and functionality.
Innovation Solution
A mountable clear display and projection system that uses transparent or clear displays mounted on surfaces, allowing users to see through them when inactive, and projects content using short throw projectors with light emitting diodes, enabling electronic displays on surfaces like windows and mirrors without obstructing views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional electronic display devices are positioned in front of windows or mirrors, then digital content can be displayed, but the view through the window or the mirror functionality is blocked
Solution Approach 1:
The display device changes its optical properties from opaque to transparent based on operational state. When inactive, the display becomes transparent allowing users to see through windows or view mirror reflections. When active, it displays digital content. This dynamic optical property change resolves the contradiction between displaying content and maintaining view/mirror functionality.
Solution Approach 2:
The display device dynamically adjusts its state between transparent and opaque modes. The transition is controlled based on operational requirements, allowing the display to adapt its properties in real-time. This dynamic behavior enables the display to serve dual purposes: maintaining surface functionality when not in use and providing digital content display when needed.
2Loss of information
If conventional electronic display devices are mounted on surfaces, then digital content can be presented, but the aesthetic appearance and visual obstruction increase
Solution Approach 1:
The display device utilizes optical property changes to maintain aesthetic appearance. In inactive state, the transparent display becomes visually imperceptible or blends with the mounting surface, preserving aesthetic appearance. When content needs to be displayed, it activates and becomes visible. This allows digital content presentation without permanent visual obstruction or aesthetic degradation.
3Object-affected harmful factors
If transparent displays are used to maintain view through windows, then view and surface functionality are preserved, but the display may not provide sufficient visibility when activated
Solution Approach 1:
The display device adjusts multiple parameters including brightness, contrast, and backlight intensity to ensure sufficient visibility when activated. These parameters are optimized based on ambient lighting conditions and operational requirements. The display maintains transparency when inactive for view preservation, but when activated, it adjusts illumination parameters to provide clear, visible content while still allowing some light transmission.
