Cheering Banner With Rigid Handle And LED Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld banners used for displaying team identification at large events are difficult to wave effectively due to their flaccidity, lacking rigidity and visibility.
Innovation Solution
A flexible banner with a removable rigid handle and integrated illumination source, utilizing a synthetic material wafer for structural support and weight distribution, allowing for enhanced swinging and visibility through centrifugal forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flexible fabric banner is used, then the banner can be easily manufactured and stored, but it becomes difficult to wave and display effectively due to flaccidity
Solution Approach 1:
The banner is divided into two separate components: a flexible fabric panel and a rigid handle. The fabric panel can be easily manufactured and stored, while the rigid handle provides structural support for waving. The handle inserts through an opening in the fabric panel, allowing the two segments to work together to resolve the contradiction between ease of manufacture and ease of operation.
2Ease of operation
If a rigid handle is added to provide structure, then the banner becomes easier to wave, but the device complexity increases
Solution Approach 1:
By separating the banner into a flexible panel and a rigid handle, the design adds minimal complexity. The handle is a simple rigid structure that inserts through an opening in the panel, providing waving capability without requiring complex mechanisms. This segmented approach maintains simplicity while improving operability.
3Shape
If the banner is made completely rigid, then it maintains shape well, but it loses flexibility and becomes difficult to store and maneuver
Solution Approach 1:
The banner uses a segmented structure where only the handle is rigid to maintain shape, while the fabric panel remains flexible for storage and maneuvering. This partial rigidity approach allows the banner to hold its shape when displayed while maintaining adaptability for storage and handling.
Solution Approach 2:
Different parts of the banner have different mechanical properties: the handle is rigid to maintain shape and provide leverage for waving, while the fabric panel is flexible to allow folding and storage. This local differentiation of material properties resolves the contradiction between shape maintenance and adaptability.

AI summary
A banner for displaying while cheering at an event venue. The banner comprises a flexible woven fabric panel bearing indicia related to a partisan of an event taking place at the event venue, a reinforced opening and an illumination source. A handle having an enlarged head penetrates the opening and is retained by a friction fitted washer slipped over the handle. The opening is at one corner of the panel and the illumination source is a light emitting diode with battery and switch all contained in a compartment at another corner.
