Dance Pole End Assembly With Tool-Free Static-Spin Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dance exercise poles require a separate tool and are slow to switch between static and spinning modes, which can be inconvenient and potentially dangerous during use.
Innovation Solution
An end assembly with a movable element that allows quick switching between static and spinning modes without additional tools, using a cam mechanism to interlock engagement elements for secure rotation restriction, ensuring safety and minimizing interruptions to the pole surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tool such as an Allen or hex key is used to screw at least one screw inwards to engage with a flat surface on the pole, then the rotation of the dance exercise pole is restricted relative to the base, but the switching between static and spinning modes is slow and requires a separate tool which may be lost
Solution Approach 1:
The patent removes the external tool (Allen key or hex key) from the system by integrating the screwing function directly into the pole structure. The movable element with cam mechanism performs the function previously requiring a separate tool, eliminating the risk of tool loss and simplifying operation.
Solution Approach 2:
The pole structure becomes self-servicing by incorporating the movable element that can be manually operated to engage or disengage the cam mechanism. The system performs its own mode switching function without requiring external tools or complex procedures.
2Reliability
If a tool such as an Allen or hex key is used to screw at least one screw inwards to engage with a flat surface on the pole, then the rotation of the dance exercise pole is restricted relative to the base, but the switching between static and spinning modes is slow
Solution Approach 1:
The movable element is pre-positioned within the pole structure with the cam mechanism ready to engage. When the user pulls the pole, the mode switching action is immediately available without requiring tool assembly or complex manipulation, significantly reducing switching time.
Solution Approach 2:
The patent introduces a dynamic, movable element that can quickly transition between positions to engage or disengage the cam mechanism. This dynamic structure enables rapid mode switching compared to static screw mechanisms that require manual tool operation.
3Ease of operation
If the end assembly includes a movable element with cam mechanism, then rapid and tool-free switching is enabled, but the device complexity increases
Solution Approach 1:
The patent merges the mode switching function with the pole structure itself by integrating the movable element and cam mechanism into the existing end assembly. This combination approach adds functionality while minimizing overall complexity compared to separate switching mechanisms.
Solution Approach 2:
The movable element serves multiple functions: it acts as a manual operating handle, a positioning mechanism, and a trigger for the cam engagement. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.

AI summary
An end assembly for a dance exercise pole. The end assembly comprises: an end part; and a connector configured for connection to a dance pole. A first engagement element (30, 68) is connected to the connector; and there is a second engagement element (18, 70) engageable with the first engagement element (30, 68). A movable element (6, 75) is movable between a first position and a second position to move at least one of the first engagement element (30, 68) or the second engagement element (18, 70) and thereby switch the end part respectively between: a first configuration with the first engagement element disengaged from the second engagement element, with the connector capable of rotation relative to the end part; and a second configuration with the first engagement element (30, 68) engaged with the second engagement element (18, 70) 'to restrict the rotation relative to the end part.
