Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescoping poles for swimming pool cleaning and other applications suffer from locking mechanism weaknesses, internal twisting, and wear, leading to collapse, slippage, and jamming under pressure and stress.
Innovation Solution
A telescoping apparatus with three interconnecting carbon fiber tubes and two locking assemblies, featuring decagon-shaped tubes and quick release locking mechanisms with relief channels for enhanced locking strength and prevention of internal twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking mechanisms are used in telescoping poles, then the device can be manufactured simply, but the locking mechanism weakens or loosens under pressure causing collapse or slippage
Solution Approach 1:
The locking mechanism is divided into multiple independent components: a collar with relief channels, a separate locking element, and positioned holes in the tubes. This segmentation allows each component to perform its specific function optimally while maintaining overall reliability under pressure.
Solution Approach 2:
The collar incorporates relief channels that change the structural parameters of the locking mechanism, allowing controlled deformation and stress distribution. This prevents the locking mechanism from weakening or loosening under pressure by providing pathways for stress relief.
2Stability of the object's composition
If round tubes are used in telescoping poles, then the manufacturing is simple, but the poles are prone to internal twisting and bending
Solution Approach 1:
The patent employs non-round tube cross-sections (such as oval or rectangular profiles) instead of traditional round tubes. This asymmetric geometry provides inherent resistance to internal twisting and bending forces, improving structural stability while the manufacturing process remains feasible through standard forming techniques.
3Reliability
If the pin hole is located above the tube holes, then the alignment is easier, but the pin pulls out of the hole causing pole failure
Solution Approach 1:
Instead of positioning the pin hole above the tube holes for easier alignment, the patent inverts this arrangement by positioning the pin hole at or below the level of the tube holes. This reversal prevents the pin from being pulled outward by leverage forces, ensuring reliable retention while maintaining adequate alignment through precision hole positioning.
4Reliability
If internal locking devices are used, then the appearance is cleaner, but the locking mechanisms are subject to wear and tear resulting in jamming
Solution Approach 1:
The patent introduces a collar as an intermediary component between the locking element and the tube holes. This collar with relief channels acts as a mediator that protects the locking mechanism from direct wear and tear, reduces stress concentrations, and prevents jamming while maintaining a clean appearance.
