Banner Frame Anchor Stakes with Angled Flanges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banners tend to sag over time due to unstable posts and improper attachment, leading to leaning, bending, or bowing.
Innovation Solution
A system comprising a banner frame mounted on anchor stakes or spikes with angled flanges that provide resistance to movement and are designed to be inserted into the ground at specific angles, preventing sagging by enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional posts are used to support the banner, then the installation is simple, but the banner sags over time due to unstable posts
Solution Approach 1:
The anchor stake is segmented into distinct functional components: a driven portion for ground insertion, a flange portion with engagement features for securing the post, and a post receptacle. This segmentation allows each component to perform its specific function optimally, providing reliable banner support while maintaining reasonable installation simplicity.
Solution Approach 2:
The anchor stake serves as an intermediary element between the ground and the banner-post system. It transfers and distributes the lateral forces from the banner into the ground through its flange engagement features, preventing post instability and banner sagging without requiring complex structural modifications to the posts themselves.
2Strength
If flanges are added to the anchor stake to prevent pulling out, then the anchoring strength is improved, but the manufacturing complexity increases
Solution Approach 1:
The flange portion is merged with the driven portion as a single integrated component of the anchor stake. The flanges extend from the driven portion and include engagement features that are formed as part of the same manufacturing process, eliminating the need for separate assembly steps and reducing overall manufacturing complexity while providing enhanced anchoring strength.
Solution Approach 2:
The flange portion serves multiple functions simultaneously: it provides lateral support to prevent post movement, engages with the post through engagement features, and distributes ground reaction forces. This multi-functionality is achieved through a single structural element that can be manufactured using standard processes, maintaining ease of production.
3Stability of the object's composition
If the anchor stake is designed with specific flange angles for resistance to movement, then the stability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The flange portion is designed with specific geometric parameters including angle ranges and dimensional tolerances that optimize resistance to lateral forces while remaining compatible with standard manufacturing capabilities. The engagement features are configured with parameters that provide sufficient stability without requiring ultra-precise manufacturing, balancing performance with manufacturability.
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 prevents banner sagging by providing a stable anchor for the posts, resisting forces from wind and weight, and allowing for adjustable and secure attachment of the banner.
Implementation Method 1
The flanges may be of any suitable shape. In some embodiments, the lower part of each flange angles upward and outward from the point of origination, thereby providing an angled edge for assisting in insertion into the ground. In one exemplary embodiment, each flange may comprise one or more holes or cut-outs that are designed to resist the anchor stake from being pulled out of the ground

AI summary
A banner frame mounted on two or more anchor stakes or spikes. The anchor stakes are configured to provide a natural anchor once driven into the ground, thereby preventing the typical leaning, bending or bowing of the posts that leads to sagging of the banner. A single anchor stake or spike may also be to support a single post for applications where a single post is needed.
