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
A compact end assembly with a movable element that allows switching between static and spinning modes without tools, using a cam mechanism to interlock engagement elements, enabling quick and tool-free mode changes.
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 relative to the base is restricted (static mode achieved), but the switching mechanism becomes slow and requires a separate tool which may be lost
Solution Approach 1:
The patent extracts the screw mechanism from the system, removing the need for separate tools. The screw is integrated into the base assembly and can be directly manipulated by the user through a hexagonal opening, eliminating the need for Allen or hex keys while maintaining the static mode locking function.
Solution Approach 2:
The base assembly is designed to be self-sufficient with an integrated screw and hexagonal opening that allows users to directly operate the mode switching mechanism without external tools. The screw itself serves as both the locking element and the interface for user interaction.
2Reliability
If a tool such as an Allen or hex key is used to screw at least one screw inwards, then the static mode is achieved, but the switching process becomes slow and time-consuming
Solution Approach 1:
The external tool requirement is extracted and removed from the system. The hexagonal opening in the base allows direct finger access to the integrated screw, enabling rapid mode switching without the time penalty of searching for, selecting, and using separate tools.
Solution Approach 2:
The screw is pre-positioned and integrated into the base assembly with a hexagonal opening designed for direct manual operation. This preliminary configuration allows users to immediately switch modes by simply turning the screw with their fingers, eliminating the time loss associated with tool preparation.
3Strength
If a separate tool is required for mode switching, then the static mode locking mechanism can be effective, but the risk of tool loss and inconvenience increases
Solution Approach 1:
The patent merges the locking mechanism with the base assembly itself. The screw is integrated into the base, and the hexagonal opening is formed directly in the base structure, combining multiple functions into a single unified component that maintains locking strength while eliminating portability issues.
Solution Approach 2:
The separate tool is extracted from the system entirely. The hexagonal opening allows the base assembly to perform the function of both the locking mechanism and the tool interface, eliminating the need to carry or manage separate tools while maintaining effective mode locking.
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 rapid and safe switching between static and spinning modes, minimizing interruptions to the dance surface and reducing the risk of accidental mode changes during performance.
Implementation Method 1
A movable element is provided which is movable between a first position and a second position to move at least one of the first engagement element and the second engagement element and thereby switch the end assembly between respectively a first configuration and a second configuration

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 is connected to the connector; and there is a second engagement element engageable with the first engagement element. A movable element is movable between a first position and a second position to move at least one of the first engagement element or the second engagement element 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 engaged with the second engagement element to restrict the rotation relative to the end part.
