Banner Mounting Bracket with Pivot Base and Spring Bias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banner mounting systems are unable to flex or rotate to deflect wind, leading to damage from wind forces, as they typically remain static and can cause the banner to assume a parachute shape, trapping wind and resulting in costly repairs or replacements.
Innovation Solution
A mounting bracket system that allows the banner pole holder to rotate around a single axis, with a biasing device to bias the pole holder to a predetermined position, preventing inward movement and maintaining the banner's tension, thereby deflecting wind without forming a parachute shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mounting system is made static to maintain structural simplicity, then the device complexity is reduced, but the banner cannot deflect wind causing damage
Solution Approach 1:
The mounting system transitions from a static structure to a dynamic one by introducing a pivot base that allows the pole holder to rotate around a vertical axis. This enables the banner to actively respond to wind forces by rotating in the direction of the wind, preventing the parachute shape formation and reducing wind-induced damage while maintaining relatively simple construction.
2Object-affected harmful factors
If the pole holder is allowed to rotate freely to deflect wind, then wind resistance is reduced, but the banner may move beyond safe angular limits
Solution Approach 1:
The biasing device applies a preliminary counteracting force to the pole holder, creating a restoring moment that opposes excessive rotation. This preliminary action prevents the banner from moving beyond safe angular limits by continuously exerting a biasing force that returns the pole holder to its original position after wind-induced rotation, thereby maintaining stability while allowing necessary movement to deflect wind.
3Adaptability or versatility
If the mounting system allows rotation to deflect wind, then the banner can move with wind forces, but additional components are required
Solution Approach 1:
The mounting system is segmented into distinct functional components: a pivot base for rotation, a pole holder for supporting the banner pole, and a biasing device for maintaining position. This segmentation allows each component to perform its specific function independently, achieving wind adaptation through rotation while keeping the overall system construction simple and manageable.
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 system effectively reduces wind-induced damage by allowing the banner to move and deflect wind forces, maintaining tension and preventing damage to the banner and mounting systems, thus reducing the need for repairs and replacements.
Implementation Method 1
The biasing device is configured to bias the pole holder to a predetermined rotational position around the single axis
Implementation Method 2
The biasing device may include one or more springs

AI summary
A mounting bracket for hanging a banner includes a pole holder configured to secure a banner pole and a pivot base pivotably connected to the pole holder. The pole holder is configured to rotate only around a single axis and is biased to a predetermined rotational position around the single axis. The pole holder is configured to hold a banner pole a few degrees from 90 degrees from the longitudinal axis of the mounting bracket. At least two springs are used to bias the pole holder toward a predetermined location on the mounting bracket. A spacer may be used with the springs to prevent over-stretching and fatigue of the springs. A bolt used to connect the components of the mounting bracket may be âTâ shaped at one end.
