Multi-Pane Window Projection System for Digital Signage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital signage technology is limited to projecting content onto a single flat surface, restricting its application to previously installed wide screens or upright walls without windowpanes, which limits its scope and advertising effectiveness.
Innovation Solution
An image projection system that utilizes a combination of multiple windowpanes on a building's outer surface as light transmission members, employing projectors and motor-driven screens to project dynamic images across these surfaces, allowing for larger-scale and more conspicuous digital signage with controlled illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If digital signage technology uses a single flat surface for projection, then the projection surface is simple and easy to implement, but the advertising effect and visual impact are limited
Solution Approach 1:
The invention divides the projection surface into multiple separate windowpanes that can be individually projected onto. Each windowpane serves as an independent projection surface, allowing the system to overcome the limitations of single-surface projection while maintaining ease of implementation through standardized pane-based projection.
Solution Approach 2:
The invention combines multiple projection surfaces (windowpanes) into a unified digital signage system. By projecting content across multiple panes simultaneously and coordinating their display, the system achieves enhanced advertising effect and visual impact while using simple, individually manageable surfaces.
2Area of stationary object
If digital signage is projected onto previously installed wide screens or upright walls, then the projection surface area is limited, but the system structure is simple
Solution Approach 1:
The invention transitions from projecting onto traditional vertical walls or wide screens to projecting onto multiple horizontal windowpanes. This dimensional shift allows utilization of previously underutilized building surfaces (window areas) to expand the effective projection surface area without adding complex structural elements.
Solution Approach 2:
The invention makes existing windowpanes serve dual purposes: their original function as building envelope elements and their new function as projection surfaces. This multi-functionality expands the available projection area without requiring dedicated signage structures, maintaining system simplicity.
3Adaptability or versatility
If multiple windowpanes are used as light transmission members for projection, then the digital signage scale and advertising effect are enhanced, but the system complexity increases
Solution Approach 1:
The system segments the projection task across multiple windowpanes, with each pane being independently projected onto. This segmentation allows the use of simple, standardized projection units rather than requiring a single complex large-format projection system, thereby enhancing scale while managing complexity through modularity.
Solution Approach 2:
The invention introduces a control device as an intermediary that coordinates the projection content across multiple windowpanes. This mediator manages the complexity of multi-pane synchronization and content distribution, allowing the system to achieve large-scale digital signage functionality while keeping individual projection units and their control simple.
