Adjustable Flag Pole Ring Attachment for Secure Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flag pole attachments are difficult to secure, lack adjustability for various diameters, and are often expensive and challenging for unskilled workers to use, especially in adverse weather conditions, requiring frequent repositioning and additional maintenance.
Innovation Solution
A polymeric flag pole attachment system comprising a ring with a rotatable pin, a ring retainer with a finger tab and tine for easy locking, and spacers for diameter adjustment, allowing secure attachment and repositioning on different diameter poles without the need for complex mechanisms or high costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional flag pole attachments are used, then the flag can be attached to the pole, but the attachment is difficult and time-consuming to secure in place
Solution Approach 1:
The attachment device is divided into separate components: a ring that fits around the pole, a flag mounting mechanism with grommets, and a retainer system. This segmentation allows each component to be independently optimized and assembled, making the overall attachment process simpler and faster than conventional integrated designs.
Solution Approach 2:
The retainer mechanism incorporates movable elements that can be easily positioned and locked into place. The dynamic design allows the retainer to be quickly adjusted to secure the ring at the desired position on the pole, reducing the time and effort required compared to static conventional attachments.
2Adaptability or versatility
If standard flag pole attachments are used, then the flag can be attached, but the attachment lacks adjustability for various diameter flag poles
Solution Approach 1:
The ring is designed with a versatile geometry that can accommodate multiple pole diameters. The retainer mechanism serves multiple functions: it secures the ring to the pole, allows for easy repositioning, and adapts to different pole sizes without requiring additional components or complex adjustment mechanisms.
Solution Approach 2:
The attachment system allows for parameter changes in pole diameter accommodation through the flexible ring design and adjustable retainer positioning. The retainer can be moved to different locations on the pole, and the ring can be compressed or expanded within reasonable limits, enabling adaptation to various pole diameters without changing the fundamental device structure.
3Reliability
If spring metal clips are used to engage grommets, then the flag can be securely attached, but the process is expensive and difficult for unskilled workers to use
Solution Approach 1:
The attachment system is designed to be self-servicing, requiring minimal skill to operate. The retainer mechanism automatically secures itself to the pole when engaged, and the ring naturally maintains its position through its geometric design. This eliminates the need for specialized techniques or tools that would be required when using spring metal clips, making it accessible to unskilled workers while maintaining reliable attachment.
4Stability of the object's composition
If conventional attachments are used, then the flag can be attached to the pole, but the flag undesirably moves up or down the pole in adverse weather conditions
Solution Approach 1:
The retainer is designed to be positioned in advance at the desired location on the pole, creating a pre-established secure point. The ring is then attached and locked by the retainer before adverse weather conditions occur. This preliminary positioning ensures the flag remains stable during wind and weather events, as the retainer-prepared attachment point resists movement more effectively than conventional attachments that lack pre-positioned securing mechanisms.

AI summary
An attachment and method of use is described for securing flags, banners and the like to flag poles. The attachment includes a ring having a rotatable pin which fits within a conventional flag grommet. A ring retainer is used to maintain the ring at a selected location along the flag pole. In order for the attachment to work with flag poles having different diameters, a ring retainer spacer and ring spacer are available for easy use during assembly. The attachment allows ease in repositioning the flag along the pole as desired.
