Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outdoor advertising structures are overly robust, expensive, and pose safety risks due to their weight and resistance to strong winds, leading to potential collapse and hazards for installation and maintenance personnel, while also compromising urban aesthetics and being prone to vandalism.
Innovation Solution
A tilting, lowerable outdoor advertising structure with a lightweight, aerodynamic design using a telescopic pedestal and mechanisms like counterweights, tension springs, and pulleys to reduce wind resistance, allowing the screen to tilt during strong winds and facilitating easy maintenance and replacement, while using a secure and efficient anchoring system for advertising materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional robust structures are used to resist strong winds, then wind resistance is improved, but weight increases and safety risks worsen
Solution Approach 1:
The patent applies the dynamics principle by designing a screen that can tilt and lower dynamically in response to wind conditions. The screen transitions from a fixed vertical position to a tilted position during strong winds, and can be lowered completely during extreme conditions. This dynamic adaptation allows the structure to resist wind forces effectively while maintaining a lightweight construction, eliminating the need for heavy robust structures.
2Reliability
If heavy robust structures are used, then wind resistance is improved, but installation and maintenance safety worsen
Solution Approach 1:
The dynamic tilting and lowering mechanism allows the screen to be positioned safely during installation and maintenance operations. The screen can be lowered to ground level or tilted to accessible positions, enabling workers to perform tasks at safe heights rather than climbing tall structures. This dramatically improves installation and maintenance safety while maintaining wind resistance through the same dynamic mechanism.
Solution Approach 2:
The structure incorporates self-service features through automated or easily operable mechanisms for tilting and lowering the screen. The telescopic pedestal and tilting mechanism can be operated without complex equipment, allowing maintenance personnel to access the screen at ground level safely. This reduces dependency on heavy cranes and specialized installation equipment.
3Reliability
If robust structures with large dimensions are used, then wind resistance is improved, but cost increases
Solution Approach 1:
The dynamic tilting and lowering mechanism replaces the need for heavy, complex robust structures. By using a lightweight screen combined with simple tilting and lowering mechanisms, the patent achieves wind resistance without increasing device complexity. The screen can be tilted to various angles and lowered completely, providing multiple positions for different wind conditions and maintenance needs.
Solution Approach 2:
The patent applies parameter changes by modifying the screen's position parameters (angle and height) rather than changing the structural parameters. Instead of building a heavier, more complex structure, the system changes the screen's orientation and elevation to adapt to wind conditions. This is achieved through the tilting mechanism and telescopic pedestal, which allow the screen to assume different positions without requiring a more complex overall structure.
4Area of stationary object
If the screen is fixed at high position, then advertising visibility is improved, but maintenance accessibility worsens
Solution Approach 1:
The dynamic lowering and tilting mechanism allows the screen to transition between high visibility positions and low maintenance positions. During normal operation, the screen is positioned high and vertically oriented for maximum advertising visibility. During maintenance, the screen can be lowered to ground level or tilted to accessible angles, enabling workers to service the screen safely without climbing tall structures.
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
The structure reduces the risk of collapse and injury during installation and maintenance, enhances urban aesthetics, and minimizes vandalism by being less accessible, while ensuring even tension and durability of advertising materials, thus reducing costs and improving safety and appearance.
Implementation Method 1
The structure to be patented is described below through several figures that represent some of the preferred execution forms, as an illustration, not a limitation. FIG. 5) shows the mechanism that turns the weight of one part of the structure into the counterweight required for tilting the screen (4) and taking it back to its vertical position.
Implementation Method 2
FIG. 6) shows a mechanism that allows the screen (4) to tilt and to go back to its vertical position by using a tightening spring (28) fixed to the foundation of the structure.
Implementation Method 3
FIG. 13) shows the operation of a winch (31) as a lifting mechanism to move the tube with the smaller diameter (3) through the tube with the bigger diameter (1).

AI summary
The invention relates to an outdoor advertising structure with a tilting, lowerable screen, formed by a pedestal and a screen whereon the advertisement is placed, and which does not put up resistance to the passage of wind. The invention has a mechanism that allows the screen to tilt during strong winds and to return to the vertical position when the wind stops or loses strength. It also has a mechanism that allows the advertising material exhibited on the screen to be constantly and uniformly held taut, especially when said advertising material is made of a type of canvas or similar material. The pedestal is formed by two tubes of different diameters, which, by means of a lifting mechanism, allow the upper screen to be lowered in order to replace the exhibited advertisement, or to carry out repairs and/or maintenance. The invention reduces to minimum accidents that occur when carrying out any intervention, as well as the likelihood of the structure collapsing. It also reduces costs relating to materials, production, cranes, transportation, lying of foundations and maintenance. The invention also reduces the amount of graffiti and undoubtedly improves the aesthetics of the urban landscape.
