Self-Supporting Projection System for Urban Digital Advertising
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing advertising systems for smart cities are limited by the need for adjacent facilities for protection and maintenance, high economic costs, inefficient energy consumption, and lack of interaction with the advertising message recipient, as well as visual pollution and high investment in digital screens like LED, LCD, or plasma screens.
Innovation Solution
A self-supporting system with a robotic arm, protective case, cooling system, image projection, video cameras, control system, sensors, and energy source that allows automated, remote monitoring and interaction with digital advertising on pre-existing structures, minimizing visual pollution and optimizing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital projection is used for advertising, then advertising flexibility and content variety are improved, but protection of the projection unit and its location become challenging
Solution Approach 1:
The projection unit is nested within a protective case that is attached to the robotic arm, creating a nested structure where the projection unit is protected from environmental conditions while remaining accessible for maintenance. The protective case acts as a shell that encloses the vulnerable projection components.
Solution Approach 2:
The robotic arm serves as an intermediary mechanism that carries the projection unit between the building (projection surface) and the protective case (maintenance location). This intermediary structure enables the projection unit to be easily moved for protection and maintenance without requiring complex installation infrastructure.
2Reliability
If a person remains at the projection place for operation and repair, then system reliability is improved, but operational complexity and cost increase
Solution Approach 1:
The system is designed to be self-sufficient with an autonomous projection unit that can operate independently. The robotic arm can autonomously retrieve the projection unit for maintenance and return it to the building, eliminating the need for constant human presence while maintaining system reliability through automated operations.
Solution Approach 2:
The system transitions from a static installation requiring constant human presence to a dynamic system where the projection unit can be automatically retrieved and returned. The robotic arm enables the system to adapt its state between operation and maintenance modes without human intervention, reducing operational complexity.
3Illumination intensity
If LED, LCD or plasma screens are used for advertising, then advertising visibility is improved, but economic cost per unit area increases significantly
Solution Approach 1:
Instead of using expensive physical display screens, the system uses a projection unit that creates visual copies of advertising content on the building surface. This copying approach replaces the need for costly LED, LCD, or plasma screens while achieving similar visual effects and advertising visibility.
Solution Approach 2:
The building surface acts as an intermediary display medium instead of expensive digital screens. The projection unit projects advertising content onto the building, using the building's existing surface as the display medium, thereby eliminating the need for costly advertising screen installations.
4Object-generated harmful factors
If projection is done on pre-existing buildings, then urban environmental impact is reduced, but protection of the projection unit from environmental conditions becomes difficult
Solution Approach 1:
The projection unit is nested within a protective case that shields it from environmental conditions such as rain, wind, and extreme temperatures. This nested structure allows the system to be installed on pre-existing buildings without compromising the protection of the vulnerable projection components.
Solution Approach 2:
The system dynamically adjusts its operation based on environmental conditions. The robotic arm can retrieve the projection unit when environmental conditions become unfavorable, and return it when conditions improve, allowing the system to maintain both urban environmental compatibility and protection of the projection unit.

AI summary
A self-supporting system for the mass communication and distribution of content and digital advertising in public spaces. The system has a mechanical structure that sets the system on a building and supports the other components. The system has a control module; a connectivity module; a sensor module; one or more human-machine interfaces; and an energy source. A method for the administration, management, and supervision of the system remotely by an administrator, and a method for receiving user inputs with the system. The system allows the use of pre-existing urban infrastructure for communication and mass distribution of content and digital advertising in public spaces with high capacity for attracting the attention of, and interacting with, the public, without need to install intrusive structures within the urban environment, with a low cost and reduced environmental impact.
