Dance Exercise Pole Base Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dance exercise poles require inconvenient height adjustments at the top, which often necessitate using a chair or ladder, and typically do not allow for rotation of pole sections relative to the base when height-locked, compromising user experience.
Innovation Solution
A dance exercise pole design featuring a base with a lower cylindrical section that rotates, an adjustable connector with an externally threaded portion, and a locking mechanism at the lower end, enabling vertical adjustment and locking of pole sections while allowing rotation, and a smooth sleeve for user engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If height adjustment is provided at the ceiling assembly, then the pole can be adjusted to fit different heights, but it requires standing on a chair or ladder to make the adjustment
Solution Approach 1:
The patent inverts the conventional approach by moving the height adjustment mechanism from the ceiling assembly to the base assembly. The base assembly now includes an adjustable section with external threading that allows height adjustment at ground level, eliminating the need to stand on chairs or ladders to access adjustment mechanisms at the top of the pole.
2Ease of operation
If height adjustment is provided at the base, then convenient height adjustment is achieved, but rotation of pole sections relative to the base is precluded
Solution Approach 1:
The patent divides the base assembly into separate functional components: a fixed base portion and an adjustable section with external threading. This segmentation allows the adjustable section to provide height adjustment through external threading while the base assembly as a whole maintains rotation capability through the adjustable section's design, resolving the contradiction between convenience and versatility.
3Ease of operation
If the pole surface is made smooth for user engagement, then user experience is improved, but adjustment mechanisms become more difficult to access
Solution Approach 1:
The patent inverts the conventional approach by moving the adjustment mechanism from the ceiling assembly to the base assembly. This allows the pole surface to remain smooth for user engagement at all heights, while the adjustment mechanism is accessible at ground level through the base assembly's external threading, eliminating the trade-off between smooth surface and mechanism accessibility.
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
Enables convenient height adjustment and locking at the lower end, allowing pole sections to rotate relative to the base, providing a smooth user interface and accommodating various floor conditions without the need for elevated adjustments.
Implementation Method 1
an externally threaded portion; a lowermost pole section having an internally threaded portion at its lower end for connection to the externally threaded portion of the connector, such that the position of the pole section is vertically adjustable by relative rotation of the pole section on the connector
Implementation Method 2
means for selectively locking the pole section against relative rotation on the connector
Implementation Method 3
a lower cylindrical section journalled for rotation on the base about a substantially vertical axis

AI summary
A dance exercise pole has a base, a lower cylindrical section journalled for rotation on the base about a substantially vertical axis, a connector extending upwardly from the upper end of the lower cylindrical section, and a lowermost pole section having an internally treaded portion at its lower end for connection to an externally treaded portion of the connector whereby the height of the pole section is vertically adjustable. A sleeve is mounted to slide over the outside of the lower cylindrical section and may be detachably connected to the lowermost pole section.
