Post Hanger Attachment With Retaining Tabs for Stable Sign Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Signs placed on posts often require significant construction to maintain a stable position, and standard posts like a 'two by four' are inadequate to hold signs or targets securely, especially in harsh environmental conditions.
Innovation Solution
A hanger attachment system for posts made from ballistically resilient steel, featuring a body with angled supporting arms and retaining tabs that fit standard dimensional lumber, allowing for secure attachment and easy installation without extensive construction, and a connector to hold signs or targets in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard dimensional lumber (e.g., two by four) is used as a post, then the post is inexpensive and readily available, but it is inadequate to hold signs or targets securely against environmental elements and impacts
Solution Approach 1:
The hanger combines ballistically resilient steel material with a specifically engineered geometry featuring angled supporting arms and retaining tabs. This composite approach uses the superior strength properties of steel while configuring it in a shape that distributes loads effectively across the dimensional lumber post, creating a composite structure that exceeds the strength of the lumber alone.
Solution Approach 2:
The hanger is divided into distinct functional segments: angled supporting arms that transfer load to the post, retaining tabs that secure the hanger to the post, and a connector portion that holds the sign. This segmentation allows each part to be optimized for its specific function, improving overall reliability without requiring a stronger post.
2Duration of action of stationary object
If significant construction is performed to build a permanent support structure, then the sign can be maintained in position for extended periods, but the complexity and time required for installation increases
Solution Approach 1:
The hanger is designed to be self-installing onto standard dimensional lumber posts through friction and mechanical interlocking via the retaining tabs and angled arms. The structure serves itself by using the post's existing geometry to secure the hanger in place without requiring additional fasteners, adhesives, or complex assembly steps, thereby reducing installation complexity while ensuring long-term durability.
Solution Approach 2:
The hanger is pre-configured with angled supporting arms and retaining tabs during manufacturing that are specifically designed to interface with standard dimensional lumber dimensions. This preliminary preparation allows the hanger to be quickly installed on any standard post without requiring field customization or complex construction activities.
3Ease of operation
If a simple single two by four post is used, then installation is straightforward, but it cannot withstand projectile impacts or harsh environmental conditions
Solution Approach 1:
The solution creates a composite system where the simple dimensional lumber post is combined with ballistically resilient steel hanger components. The steel material provides resistance to projectile impacts and environmental degradation, while the lumber post maintains ease of installation. The angled supporting arms and retaining tabs create a composite structure where the strengths of each material complement each other.
Solution Approach 2:
The hanger is designed with ballistically resilient steel material that serves as a cushioning element against projectile impacts before they reach the post. The angled supporting arms distribute impact forces across a wider area of the post, preventing concentrated damage. This beforehand cushioning allows the simple post structure to withstand harmful factors it would otherwise be vulnerable to.
