Solution Overview
Problem
Existing gate systems for entry and movement, such as automatic ticket gates and security gates, lack effective means to draw attention and present eye-catching information to travelers.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional display methods (stickers, printed information, LED display units) are used in gate systems, then information can be provided to travelers, but the information is not eye-catching and fails to draw attention effectively
Solution Approach 1:
The patent transitions from traditional two-dimensional flat displays (stickers, LED screens) to three-dimensional volumetric light field displays. By using light guide elements with light focusing portions, the system creates images that occupy three-dimensional space, allowing light to converge at specific points or lines outside the light guide element, thereby forming volumetric images that are more eye-catching and attention-grabbing
Solution Approach 2:
The patent introduces a light guide element as an intermediary between the light source and the viewer. This light guide element contains light focusing portions that manipulate light paths, converging light at specific convergence points or lines in three-dimensional space. The light guide element acts as a mediator that transforms ordinary light into focused volumetric light fields, enabling the creation of eye-catching 3D images without requiring complex direct lighting systems
2Ease of operation
If information is displayed using conventional means, then basic information delivery is achieved, but the eye-catching nature and ability to draw attention of approaching travelers is insufficient
Solution Approach 1:
The patent utilizes variations in light properties (analogous to color changes in the TRIZ framework) by controlling light convergence and intensity at different spatial locations. The light focusing portions create varying light intensities and patterns in three-dimensional space, forming visually distinct images that can change appearance based on viewing angle and position, thereby enhancing attention-grabbing capability and information effectiveness
3Adaptability or versatility
If multiple display devices are used to provide comprehensive information, then information completeness improves, but device complexity and space requirements increase
Solution Approach 1:
The patent integrates multiple display functions into a single compact light guide element structure. By embedding light focusing portions within the light guide element, the system can generate multiple volumetric images or different image configurations from a single integrated component, reducing the need for multiple separate display devices and minimizing space requirements while maintaining versatile information presentation capability
Solution Approach 2:
The light guide element serves multiple functions simultaneously: it guides light from the light source, focuses light at specific convergence points to form images, and can display multiple different images by activating different light focusing portions. This multi-functionality allows a single compact component to replace what would traditionally require multiple separate display devices, enhancing adaptability while reducing footprint

Function Achieved in This Case
The display system effectively presents eye-catching information to travelers, improving attention draw and visibility, while also indicating passage permission, enhancing the gate system's functionality and user experience.
Implementation Method 1
a light guide element configured to guide incident light from the light source
Implementation Method 2
a plurality of light focusing portions configured to change the path of the incident light toward the emission surface, causing the light output to converge toward a convergence point or convergence line outside the light guide element
Implementation Method 3
a plurality of light focusing portions configured to change the path of the incident light toward the emission surface
Implementation Method 4
causing the light output to converge toward a convergence point or convergence line outside the light guide element or to radiate from a convergence point or convergence line outside the light guide element and thereby form an image outside the light guide element
