Collapsible Pole Stand With V-Shaped Cradle Against Pole Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole stands for utility poles are bulky, prone to mechanical failure, and have a U-shaped cradle that is size-specific, making them inefficient for framing and prone to pole rotation during line work.
Innovation Solution
A collapsible pole stand with a V-shaped cradle and robust rotation mechanism, featuring a cylindrical shaft, upward and downward V-shaped arms and legs, and a stopper to prevent excessive rotation, allowing for secure holding of poles of varying sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a U-shaped cradle is used to hold the pole, then the pole can be held during framing, but the pole rotates side-to-side making framing more difficult
Solution Approach 1:
The patent changes the cradle shape from a symmetric U-shape to an asymmetric V-shape with specific angular geometry. The V-shaped cradle has arms positioned at angles that create stable contact points with the pole, preventing side-to-side rotation while maintaining ease of framing operations.
2Ease of operation
If existing pole stands are used, then the pole can be held during framing, but the rotation mechanism wears out and is prone to failure
Solution Approach 1:
The patent removes the problematic rotation mechanism entirely from the design. Instead of using a mechanical rotation joint that wears out, the stand uses a fixed V-shaped cradle structure that provides stable pole holding without requiring any rotating components, thereby eliminating the reliability issue.
3Ease of operation
If existing pole stands are used, then the pole can be held during framing, but they take a significant amount of space to store
Solution Approach 1:
The patent designs the stand components to nest within each other when collapsed. The legs and arms can be positioned to fit inside the overall structure, creating a compact storage configuration that minimizes volume while maintaining full framing support capability when deployed.
4Adaptability or versatility
If a U-shaped cradle specific to a particular sized pole is used, then that specific pole size can be held, but it is too small or too large for certain poles
Solution Approach 1:
The patent designs the V-shaped cradle with adjustable parameters and geometric flexibility that allow it to accommodate multiple pole sizes effectively. The cradle can be adjusted or configured to work with different pole diameters while maintaining proper framing effectiveness, making the stand universal rather than size-specific.

AI summary
A collapsible pole stand for holding a pole may include a shaft; a pair of arms extending from a top end of the shaft, wherein the pair of arms form an upward V-shape; a middle collar rotatably engaged with a middle section of the shaft; a pair of long legs attached to and extending from the middle collar, wherein the pair of long legs form a downward V-shape; a lower collar engaged with a bottom section of the shaft; and a pair of short legs attached to and extending from the lower collar, wherein the pair of short legs form a smaller downward V-shape.
