Swivel Hanger Stop Structure for Free Rotation After Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swivel hangers often require multiple components and are difficult to install, lacking a simple and efficient mechanism to ensure free swivel movement after installation.
Innovation Solution
A swivel hanger system with a stop structure that limits the insertion distance of the anchor member into the support member, maintaining a selected distance for unhindered swivel movement, using a flange or tool flange to prevent over-insertion and ensure a gap for free rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing swivel hangers use multiple components to facilitate swivel connection, then the swivel function is achieved, but the device complexity increases and installation becomes difficult
Solution Approach 1:
The patent combines multiple components into a single integrated swivel hanger assembly. The swivel member, anchor member, and stop structure are designed as unified components that work together, eliminating the need for separate parts while maintaining the swivel function. This merging approach reduces device complexity and simplifies installation.
Solution Approach 2:
The swivel hanger is designed as a universal component that performs multiple functions: anchoring to the support surface, enabling swivel movement, and maintaining proper spacing. The integrated design allows a single component to fulfill roles that traditionally required multiple separate parts.
2Strength
If anchor member is inserted deeply into support member, then anchoring strength is improved, but the swivel member gets pinched and free rotation is restricted
Solution Approach 1:
The stop structure is pre-configured on the anchor member at a specific distance from its tip. This preliminary positioning ensures that when the anchor member is inserted into the support surface, the stop structure automatically prevents over-insertion by contacting the support surface first, thereby preserving the gap needed for free swivel movement while still achieving adequate anchoring strength.
Solution Approach 2:
The stop structure acts as an intermediary element between the anchor member and the swivel member. It mediates the insertion depth by providing a physical barrier that contacts the support surface, thereby controlling the distance between the anchor head and support surface without requiring complex adjustment mechanisms.
3Ease of manufacture
If no stop structure is used, then installation is simpler, but the anchor member insertion distance cannot be controlled and swivel movement is restricted
Solution Approach 1:
The stop structure is designed as a self-regulating feature that automatically controls insertion depth without requiring external tools or complex adjustment procedures. During installation, the stop structure naturally contacts the support surface to prevent over-insertion, making the system self-servicing and maintaining both simplicity and control.

AI summary
A swivel hanger system includes an anchor member with an anchor head disposed at an end of the anchor member and an elongated body, where at least a portion of the elongated body is configured to be inserted into a support member when the system is connected with the support member. The system also includes a swivel member with an open end extending to a hollow interior of the swivel member, where the open end is configured to rotatably couple with the anchor head such that the anchor head is located within the hollow interior and the elongated body extends through the swivel member open end. The system further includes a stop structure to limit an insertion distance at which the anchor member is inserted into the support member.
