Solution Overview
Problem
Conventional advertisements are limited by fixed contents and locations, failing to effectively reach moving vehicles and dynamic environments.
Innovation Solution
A mobile advertisement system installed on vehicle back windows, equipped with GPS, network communication, and light sensors, which displays location-based advertisements only when vehicles are detected and adjusts brightness based on environmental light, ensuring targeted and dynamic ad delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional advertisements are displayed in fixed locations with fixed contents, then the advertisement system is simple and stable, but the advertisement cannot effectively reach moving vehicles and dynamic environments
Solution Approach 1:
The advertisement system transitions from static to dynamic operation. The display screen is controlled to activate only when vehicles are detected by the video camera, and advertisements are selected based on real-time GPS location data. This dynamic adaptation allows the system to effectively reach moving vehicles while maintaining operational simplicity through automated control logic.
Solution Approach 2:
The system implements feedback mechanisms where the video camera continuously monitors for vehicles, and the GPS module provides real-time location information. Based on this feedback, the control module automatically selects and displays relevant advertisements, enabling the system to adapt to dynamic environments without requiring complex manual intervention.
2Productivity
If the display screen operates continuously to ensure advertisement visibility, then advertisement reach is maximized, but energy consumption increases
Solution Approach 1:
Instead of continuous operation, the display screen operates periodically based on vehicle detection. The video camera periodically scans for vehicles, and the display activates only during periods when vehicles are present. This periodic action ensures advertisement delivery effectiveness is maintained while significantly reducing energy consumption during periods when no vehicles are nearby.
3Illumination intensity
If the display brightness is set to maximum for visibility in all lighting conditions, then advertisement visibility is ensured, but energy consumption and glare to drivers increase
Solution Approach 1:
The display brightness parameter is dynamically adjusted based on ambient light conditions detected by the light sensor. In bright conditions, the display reduces brightness to minimize glare to drivers and reduce energy consumption. In darker conditions, the display increases brightness to maintain visibility. This parameter adjustment resolves the contradiction between visibility and harmful effects.
4Measurement precision
If location-based advertisement targeting is implemented using GPS, then advertisement precision is improved, but device complexity and power consumption increase
Solution Approach 1:
The GPS module serves multiple functions: it provides location data for advertisement selection, tracks vehicle movement patterns, and enables geofencing capabilities. By making the GPS component multi-functional, the system achieves precise location-based targeting without proportionally increasing overall system complexity. The same hardware infrastructure supports multiple advertisement delivery strategies.
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
Enables targeted and efficient advertisement delivery to moving vehicles, enhancing reach and engagement through location-based and context-aware advertising.
Implementation Method 1
The light sensor is positioned on the display screen facing outside to detect environmental light intensity outside of the vehicle
Implementation Method 2
The GPS module receives GPS satellite signal through a GPS antenna to determine the GPS location of the mobile advertisement system

AI summary
A mobile advertisement system mounted on a back window of a vehicle using suction cups is presented according to aspects of present disclosure. In certain embodiments, the mobile advertisement system connects wirelessly to a mobile advertisement server, sends its GPS location updates periodically to mobile advertisement server, receives advertisements and delivery instructions from mobile advertisement server in response to the GPS location updates sent, displays advertisements on the display screen of the mobile advertisement system according to the corresponding delivery instructions when at least one automobile is detected, and transmits delivery confirmations to mobile advertisement server after each advertisement is displayed according to the corresponding delivery instructions. A video camera detects whether there are any automobile behind, and mobile advertisement system will not display advertisements when there is no automobile behind. brightness of advertisement display is in directly proportional to light intensity outside detected by a light sensor.
