Telescopic Flagpole Friction Locking for Protrusion Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopic flagpoles experience issues with tubular members sliding relative to each other during extension and retraction, making it difficult to position fastening protrusions correctly and potentially damaging them due to collisions.
Innovation Solution
The telescopic flagpole incorporates tubular members with resistance members and resilient fastening mechanisms between adjacent pairs, increasing friction and preventing relative movement, while allowing conversion between retracted and fixed states to maintain proper alignment of fastening protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional resilient fastening units are used between tubular members, then the flagpole can be extended and retracted, but the tubular members slide quickly relative to each other making it difficult to position fastening protrusions correctly
Solution Approach 1:
The resistance member is pre-installed on the outer tubular member before the fastening protrusion is inserted. This preliminary placement creates a controlled environment that guides the fastening protrusion into correct alignment, preventing misalignment issues that occur when trying to position fastenings during the extension process itself
2Ease of operation
If conventional resilient fastening units are used between tubular members, then the flagpole can be extended and retracted, but the fastening protrusions may be damaged by collision with tubular members
Solution Approach 1:
The resistance member acts as a cushioning element that is already in place between tubular members. When the fastening protrusion approaches during extension or retraction, the resistance member absorbs impact energy and prevents direct collision damage to the fastening protrusion, thereby protecting this critical component
3Adaptability or versatility
If tubular members are telescopically connected with resilient fastening units, then the flagpole achieves telescopic functionality, but the fastening protrusions may be misaligned during quick sliding
Solution Approach 1:
The resistance member serves as an intermediary element between the tubular members and the fastening protrusion. It mediates the interaction by providing a controlled resistance force that slows and guides the relative movement, ensuring that the fastening protrusion aligns precisely with the through hole during the telescopic operation
Applied Scientific Principles

Implementation Method 1
The resistance member is disposed between and abuts against the respective adjacent pair of the at least two tubular members to increase friction between the respective adjacent pair of the at least two tubular members
Implementation Method 2
The resilient fastening mechanism is mounted to a respective general lower end portion, and includes a fastening protrusion being resiliently and radially movable

AI summary
A telescopic flagpole includes tubular members. A resistance member is disposed between and abuts against a respective adjacent pair of the tubular members. A resilient fastening mechanism is mounted to a lower end portion of a respective tubular member, and includes a fastening protrusion. When the telescopic flagpole is in a retracted state, the fastening protrusion abuts against an inner surface of an outer one of the respective adjacent pair of the tubular members. When the telescopic flagpole is in a fixed state, the resistance member is disposed between and abuts against the lower end portion of one of the respective adjacent pair of the tubular members and a upper end portion of another one of the respective adjacent pair of the tubular members, and the fastening protrusion protrudes outwardly from an upper through hole of the another one of the respective adjacent pair of the tubular members.
