Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor advertising signs lack effective wind resistance, often requiring user intervention to maintain structure and are inefficient in withstanding severe weather conditions, and fail to allow wind flow through the panels while maintaining stability.
Innovation Solution
A wind-resistant sign assembly featuring sign panels coupled to support members via spring-loaded hinges, allowing independent rotation and bi-directional movement to accommodate wind flow without user intervention, with panels returning to a static position when forces subside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the sign is made rigid and fixed to resist wind, then structural stability is improved, but the sign cannot allow wind flow through and may fall over in severe conditions
Solution Approach 1:
The sign is divided into multiple independent panels that can rotate relative to each other and to the support members. This segmentation allows each panel to move independently in response to wind forces, enabling the structure to flex and allow wind flow through while maintaining overall stability.
Solution Approach 2:
The sign structure transitions from a static rigid design to a dynamic system where panels can rotate and move. The hinges provide rotational freedom, and the spring-loaded mechanisms enable automatic return to original position, creating a dynamic response to wind loads that prevents structural failure.
2Object-affected harmful factors
If the sign panels are designed to break away or pivot to allow wind flow, then wind resistance is improved, but the structural integrity and display quality deteriorates
Solution Approach 1:
The design converts the harmful wind force into a beneficial automatic resetting mechanism. When wind blows, panels rotate and allow wind flow through, reducing stress. When wind subsides, spring-loaded hinges automatically return panels to their original display position, converting the wind-induced movement into a self-resetting feature that maintains structural integrity.
Solution Approach 2:
The sign structure is self-regulating through spring-loaded hinges that automatically return panels to their original position after wind exposure. This self-service mechanism eliminates the need for manual intervention and maintains structural integrity without requiring external assistance or complex control systems.
3Stability of the object's composition
If manual intervention is required to reset the sign after wind exposure, then structural integrity is maintained, but ease of operation and time efficiency worsen
Solution Approach 1:
The spring-loaded hinge mechanism provides automatic reset functionality, allowing the sign to return to its original position without user intervention. This self-service feature eliminates the need for manual cranking or resetting operations, significantly improving ease of operation while maintaining structural integrity.
Solution Approach 2:
The design replaces manual mechanical resetting operations with an automatic spring-loaded mechanism. Instead of requiring users to physically crank or force panels back into position, the spring mechanism automatically performs the resetting action, eliminating the need for user intervention and reducing maintenance time.
4Object-affected harmful factors
If multiple panels are used to allow wind flow through, then wind resistance is improved, but device complexity increases
Solution Approach 1:
The sign is divided into multiple panels connected by hinges, creating a segmented structure that allows wind flow through. While this increases the number of components, the modular nature of the segmentation allows for standardized manufacturing and assembly, which can offset the apparent complexity.
Solution Approach 2:
The hinge mechanism serves multiple functions: it connects panels to support members, allows rotational movement for wind flow, and incorporates spring-loaded elements for automatic resetting. This multi-functionality reduces the need for separate components, effectively managing device complexity while achieving wind resistance.

AI summary
A wind-resistant sign assembly that includes vertical support members coupled to multiple horizontally oriented sign panels that substantially span a length separating the support members. The sign panels are disposed in a static position, wherein they are disposed at a substantially planar configuration with one another and are operably configured to individually rotate to a dynamic position when exposed to a force generated by incoming wind. The dynamic position includes the front surface of one of the plurality of sign panels disposed at an acute angle with respect to the front surface of at least one other adjacent sign panel, thereby defining a gap between said sign panels to permit the entry and egress of the wind through the sign, and return, through use of one or more hinge and spring members, to the static position.
