Transparent Barrier Assembly with Embedded LED Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often find it difficult to recognize the current direction of passage and the operational status of passage barriers in access control systems, leading to reduced user comfort and throughput, especially when barriers are defective or not ready for use.
Innovation Solution
A blocking body arrangement comprising two essentially optically transparent blocking bodies connected by a transparent separating layer and equipped with a light source device for coupling light into each body, allowing for visible indication of passage direction and operational status through different color illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a small screen or display is used to show passage direction, then device complexity is reduced, but user comfort and visibility are insufficient
Solution Approach 1:
The patent uses color-changing light sources (LEDs) embedded in the barrier assembly to indicate passage direction and operational status. Different colors (e.g., green for passable, red for impassable) provide clear visual information to users, replacing the need for complex display screens while significantly improving visibility and user comfort.
Solution Approach 2:
The indication function is merged into the barrier assembly itself by embedding light sources within the barrier structure. This integration eliminates the need for separate display devices, reducing overall system complexity while providing prominent, always-visible indication directly at the barrier location.
2Strength
If barriers are made opaque for structural strength, then strength is improved, but visibility and user comfort deteriorate
Solution Approach 1:
The barrier assembly uses composite construction with transparent or translucent materials that maintain structural strength while allowing light transmission. The embedded light sources work with these materials to provide both the necessary mechanical strength and the desired visual indication, resolving the contradiction between opacity for strength and transparency for visibility.
3Productivity
If detailed information is displayed only at the gate, then device complexity is reduced, but throughput is reduced due to late user awareness
Solution Approach 1:
The light sources provide passage direction information in advance, before users reach the gate, by indicating the operational status and direction from a distance. This preliminary indication allows users to approach the correct gate proactively, reducing waiting time and improving throughput without requiring complex display systems.
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
Improves user comfort and increases throughput by providing a large, visible area to display passage direction and operational status, enabling clear indication of passable or impassable directions and detecting operational states like defects or maintenance.
Implementation Method 1
The light source device (110) is configured to couple light into the first light coupling surface (116) and/or the second light coupling surface (118)
