Multi-Point Contact Hanger Design to Reduce Rotational Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for suspending objects to be painted or sealed are inefficient due to rotational movement and space usage, leading to delays and potential damage from object contact before drying.
Innovation Solution
A hanger design featuring a top hook with two-point contact on a hanging rod and a wavy base with stable low points for side hooks, reducing rotational motion and allowing closer object placement without contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If objects are suspended from a single hanging rod, then all sides of the object can be painted or sealed at once, but the objects can easily sway and move around reducing space efficiency
Solution Approach 1:
The top hook is segmented into multiple straight sides (at least three) that contact the hanging rod at multiple discrete points along its length, rather than a single point contact. This segmentation distributes the suspension force and reduces rotational movement, allowing objects to be placed closer together on the rod.
Solution Approach 2:
The invention transitions from single-point contact (0D) to multi-point contact along the length of the rod (1D), effectively using the longitudinal dimension of the rod to stabilize the hanger and reduce its rotational degrees of freedom.
2Area of stationary object
If objects are placed closer together on the hanging rod, then space efficiency improves, but objects may touch and ruin the aesthetic look before drying
Solution Approach 1:
The top hook's multiple straight sides create multiple contact points with the rod, segmenting the contact interface to reduce rotational movement and stabilize the suspended object, preventing contact with adjacent objects.
Solution Approach 2:
The hanger design preemptively reduces rotational movement through its geometric configuration before objects are suspended, ensuring stability is established in advance to prevent contact damage during the drying process.
3Ease of operation
If a traditional single-point hook is used, then the hanger can rotate freely on the rod, but this rotational movement causes objects to sway and requires more space between them
Solution Approach 1:
The top hook is divided into multiple straight sides that contact the rod at multiple points, segmenting the rotational freedom into controlled segments while maintaining ease of suspension and installation.

AI summary
A hanger is provided that remains relatively stable and does not rotate in a direction a hanging rod extends from which the hanger is suspended. The hanger comprises a top hook which is configured with multiple straight sides with adjacent straight sides connected at angles, wherein two adjacent sides are connected at an angle via a high point, wherein the high point is a highest point of the top hook. The two adjacent straight sides connected via the high point are arranged to contact the hanging rod on opposing sides when suspended from the hanging rod. The top hook is connected to one or more arms which are connected to base. The base includes a wavy portion which includes one or more peaks and one or more low points, wherein a first low point is configured at a midpoint of the base and the first low point is in line with the high point of the top along a centerline.
