Parking Gate Barrier Rod Projection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking gate barrier rod systems lack the ability to dynamically project personalized digital media content to vehicles arriving at parking gates while avoiding dazzling effects when the gate opens, and they do not utilize advanced user recognition or personalized advertising effectively.
Innovation Solution
A parking gate barrier rod projection system comprising a high-gain projection screen material attached to the barrier rod, a projector for displaying digital media content, and sensors to control projection based on gate opening, combined with a car recognition module for personalized content delivery and an application for user identification, enabling dynamic and relevant advertising.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the projector continuously projects digital media content on the barrier rod, then advertising effectiveness is improved, but dazzling effect occurs when the gate opens
Solution Approach 1:
The projector operates periodically by detecting the gate opening state through sensors. When the gate is closed, the projector displays advertising content; when the gate opens, the projector stops or darkens the projection. This periodic operation based on gate state changes ensures continuous advertising delivery while preventing dazzling effects during gate opening.
2Device complexity
If the system uses basic projection without user recognition, then device complexity is reduced, but personalized content delivery capability is worsened
Solution Approach 1:
The projection system is designed with multi-functionality to serve both simple and personalized advertising needs. The system can operate in two modes: basic projection for general advertising and personalized projection when user recognition data is available. The sensor module detects user presence and the controller adjusts content based on recognition data, allowing the system to adapt its complexity level according to available information while maintaining a unified hardware platform.
3Object-affected harmful factors
If the projector stops projection when gate opens, then dazzling effect is avoided, but continuous advertising exposure is reduced
Solution Approach 1:
The system uses sensors to detect gate opening in advance and pre-adjusts the projection state before the gate actually opens. By detecting the gate state change and responding proactively, the system stops or darkens projection just in time to avoid dazzling effects while minimizing interruption to advertising exposure. This preliminary detection and response mechanism ensures seamless transition between advertising display and gate opening states.

AI summary
The subject matter discloses a parking gate barrier rod projecting system, the system comprising: a projection screen material attached to at least a portion of a parking gate rod and a projector. The projector is adapted to project digital content on the projection screen material. The digital content is adapted to be fitted on the front projection screen material to thereby allowing a person in a vehicle arriving at the parking gate rod to view the digital content. A sensor or a camera may detect when the parking gate barrier rod is opened and may send a control command to the projector to stop projecting or to darken the projecting in order to avoid dazzling of a person in the vehicle.
