Solution Overview
Problem
Existing digital billboards lack multifunctionality and adaptability to various environments, failing to effectively target specific audiences and provide dynamic, context-aware messaging.
Innovation Solution
A digital billboard system featuring high-definition display panels, a resource bay with communication and charging capabilities, and removable modules that can be customized for different deployments, allowing for local and remote messaging, environmental data collection, and user interaction through NFC and Bluetooth, enabling context-aware advertising and feedback mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a digital billboard is designed with fixed functionality, then the device complexity is reduced, but the adaptability to various environments and audiences is worsened
Solution Approach 1:
The digital billboard is divided into modular components including display panels, resource bays, and removable modules that can be independently configured. Each module can be selectively attached or removed to adapt the billboard to different deployment environments while maintaining manageable system complexity through standardized interfaces.
Solution Approach 2:
The billboard incorporates universal interfaces and standardized connection protocols that enable the same hardware platform to serve multiple functions across different environments. The removable modules can be swapped to provide different capabilities (e.g., charging, environmental sensing, communication) based on deployment requirements.
2Adaptability or versatility
If the billboard uses static messaging, then the device complexity is reduced, but the ability to provide dynamic, context-aware messaging is worsened
Solution Approach 1:
The messaging system transitions from static to dynamic by incorporating real-time environmental data collection through sensors and wireless communication capabilities. The billboard can automatically adjust displayed content based on changing conditions such as time of day, weather, audience demographics, and local events, enabling context-aware messaging.
Solution Approach 2:
The system implements feedback mechanisms where environmental sensors continuously monitor conditions and feed this information to the messaging control system. This enables the billboard to respond to real-time changes in the environment and adjust its messaging accordingly, creating a closed-loop system that adapts to contextual variations.
3Measurement precision
If the billboard lacks environmental data collection, then the device complexity is reduced, but the audience targeting precision is worsened
Solution Approach 1:
Environmental data collection is achieved through intermediary sensor modules that act as mediators between the physical environment and the messaging system. These sensors collect data about surrounding conditions, audience characteristics, and contextual information, then transmit this information to the control system for processing and messaging generation.
