Folding Banner Support Assembly Wind Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banner support systems are prone to instability and risk of falling under strong winds due to their non-deformable design, and the current fixing brackets are cumbersome and not adaptable to various support shapes, making banner replacement time-consuming and risky.
Innovation Solution
A folding banner support assembly featuring flexible and/or folding rods with multiple mobile parts, including a fixed portion and movable portions connected by hinging means, which can rotate to reduce the impact surface area when hit by wind, and a quick-fixing mechanism using adjustable belts and hooks to secure the banner to any support shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid brackets are used to fix the banner to the support, then the banner is firmly secured, but the support may fall under strong wind due to inability to deform
Solution Approach 1:
The patent applies the dynamics principle by making the rod flexible instead of rigid, allowing it to deform under wind load. The rod is constructed with multiple segments that can bend relative to each other, enabling the banner to absorb wind energy through controlled deformation rather than transferring all force to the support structure.
Solution Approach 2:
The patent changes the physical parameter of the rod from rigid to flexible. This parameter change allows the rod to adapt its stiffness characteristics, enabling it to remain firm during normal conditions while deforming under excessive wind load to protect the support structure.
2Strength
If traditional brackets are used for fixing the banner, then the banner is securely attached, but the brackets must be mounted and dismounted every time the banner needs to be replaced, making it time-consuming and risky
Solution Approach 1:
The patent applies segmentation by dividing the rod into multiple detachable segments. This allows the banner to be quickly removed and replaced by simply detaching and reattaching the rod segments, eliminating the need to mount and dismount traditional brackets each time.
Solution Approach 2:
The patent enables dynamic adjustment and quick release of the banner through the flexible rod design. The rod can be rapidly detached and reattached, allowing for quick banner replacement without the time-consuming process of mounting and dismounting traditional fixed brackets.
3Strength
If non-deformable brackets are used, then the banner is firmly fixed, but the brackets are not suitable for fixing the banner to all kinds of support shapes
Solution Approach 1:
The patent changes the physical parameter of the fixation element from rigid to flexible. This parameter change allows the rod to adapt to various support shapes and sizes, as the flexible material can conform to different geometries while maintaining secure attachment.
Solution Approach 2:
The patent uses a flexible rod instead of rigid brackets. This flexible element can wrap around and conform to different support shapes, providing secure fixation across various support types without requiring shape-specific bracket designs.
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 flexible rod design reduces wind impact, enhancing stability and preventing support collapse, while the quick-fixing mechanism allows for rapid and easy banner replacement without the need for extensive lifting or disassembly.
Implementation Method 1
hinging means that hinge the mobile portion to the fixed portion, in such a way to let the mobile portion rotate with respect to the fixed portion around a hinging axis that is orthogonal to said longitudinal axis of the fixed portion
