Telescopic Pole Locking Assembly to Prevent Slippage Under Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic poles for swimming pool cleaning and other applications often experience locking mechanism failure under pressure, leading to collapse or slippage due to weakened locking means and poor grip security, resulting in alignment issues and jamming.
Innovation Solution
A telescoping pole design featuring three interconnecting tubes with angled locking pins and a spring mechanism, secured by a collar housing and actuator button, providing stable and secure extension with a detachable grip for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If prior locking mechanisms are used in telescopic poles, then the pole can be extended and positioned, but the locking mechanism weakens or loosens under pressure causing collapse or slippage
Solution Approach 1:
The patent inverts the traditional locking approach by using spring pressure to force the pin OUT of the hole, rather than forcing it IN. This reversal changes the alignment requirements and prevents the pin from pulling out under pressure, as the spring continuously pushes the pin against the aperture wall, creating a more reliable locking mechanism under load.
Solution Approach 2:
The spring mechanism applies preliminary anti-action by continuously pushing the pin against the aperture wall before pressure is applied. This pre-positioning ensures the pin is already engaged and resistant to the upcoming pressure load, preventing collapse or slippage that would occur with traditional locking mechanisms.
2Ease of manufacture
If the pin hole is located above the tube holes for alignment, then the pole can be assembled, but the pin pulls up and out of the hole causing failure
Solution Approach 1:
The patent inverts the traditional locking approach by using spring pressure to force the pin OUT of the hole, rather than forcing it IN. This reversal changes the alignment requirements and prevents the pin from pulling out under pressure, as the spring continuously pushes the pin against the aperture wall, creating a more reliable locking mechanism under load.
3Ease of operation
If traditional spring pressure locking is used, then the pole can be locked in position, but the grip fails to secure tightly allowing slippage
Solution Approach 1:
The spring mechanism applies preliminary anti-action by continuously pushing the pin against the aperture wall before pressure is applied. This pre-positioning ensures the pin is already engaged and resistant to the upcoming pressure load, preventing collapse or slippage that would occur with traditional locking mechanisms.
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
The solution ensures the telescoping pole maintains integrity under high pressure and stress, remains stable during use, and is easy to assemble and disassemble, offering reliable operation with various tools.
Implementation Method 1
The locking assemblies include a pin or other fastening device is preferably attached to an angled arm element and secured by a screw, pin, bolt, or other fastening means to the collar or housing. An actuator button is pressed to depress the pin or other detent means into a selected aperture in the inner tube
