Signage Panel Rear Display Using Projection Technology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road signage panels only utilize their front faces for information display, leaving the rear face as an unused surface, which could potentially double the display area if utilized, but integrating a dual-sided display system into these panels is not feasible due to high replacement costs and regulatory constraints.
Innovation Solution
Incorporating an optical and/or electronic display system, such as electronic screens or light projectors, onto the rear face of the signage panel to display information, which can be remotely controlled via a communication module, allowing for dynamic and attention-catching advertising or informative content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a dual-sided display system is integrated into existing signage panels, then the display surface area is doubled, but the replacement cost and regulatory compliance complexity increase significantly
Solution Approach 1:
The patent uses projection technology to create a virtual copy of the display content on the rear face of the panel. Instead of physically installing a second display panel (which would require replacement and regulatory approval), the system projects advertising content onto the rear face, effectively copying the display function without the associated costs and compliance issues.
2Area of moving object
If the rear face of signage panels is left unused, then regulatory compliance and manufacturing simplicity are maintained, but the display surface area is wasted
Solution Approach 1:
The patent introduces a projector as an intermediary device mounted on the support structure behind the panel. This intermediary projects content onto the rear face of the panel, enabling display functionality without modifying the panel itself. The projector acts as a mediator between the control system and the panel rear face, adding display capability while keeping the panel structure simple and unchanged.
3Productivity
If traditional single-sided signage panels are used, then manufacturing and installation are simple, but the information dissemination capability is limited to one direction
Solution Approach 1:
The patent makes the signage panel system multi-functional by enabling it to display information on both its front and rear faces. The front face continues to display traditional road information, while the rear face displays advertising content through projection. This universal display capability allows the same panel structure to serve multiple purposes: traffic information dissemination and advertising, thereby improving information dissemination capability without significantly increasing system complexity.
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
This solution enables the use of the rear face for information display, effectively doubling the available display surface without the need for replacing existing signage panels, thus enhancing information dissemination without incurring high costs or violating regulatory standards.
Implementation Method 1
the display system comprises a light projector arranged to project information onto the rear face of the display plate
