Titanium Lattice Ski Pole for Buckling Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern ski poles made of carbon fibers or aluminum are vulnerable to breaking under lateral forces and bending, necessitating a material with higher strength-to-weight ratio and resistance to buckling.
Innovation Solution
A ski pole design incorporating a hollow titanium lattice or grid structure, primarily in the lower part, which is lightweight and provides enhanced resistance to breaking and buckling, with optional connection to other pole parts via glue or threading.

1Weight of moving object
If ski poles are made lightweight using carbon fiber or titanium, then weight is reduced, but cost increases
Solution Approach 1:
The ski pole is divided into multiple sections that can be independently manufactured and assembled. The shaft is segmented into telescopic sections, allowing each segment to be produced separately using cost-effective materials and processes, then combined to achieve the desired lightweight performance without requiring expensive monolithic construction
Solution Approach 2:
The telescopic shaft sections are designed to nest within each other, with inner sections fitting into outer sections. This nesting arrangement reduces overall pole length and weight while allowing each section to be manufactured independently at lower cost, avoiding the need for expensive solid-state construction throughout the entire pole length

If grip materials are made highly grippy, then grip performance is improved, but skin compatibility worsens due to allergenic reactions
Solution Approach 1:
The grip surface is treated with a selective coating that provides enhanced grip properties only in specific contact areas, while maintaining skin-friendly base materials in other regions. This localized enhancement allows improved grip performance without requiring the entire grip surface to be made from highly grippy but allergenic materials
Solution Approach 2:
A biocompatible intermediate coating layer is applied between the grip structure and the user's hand. This intermediate layer acts as a mediator that provides sufficient friction for grip control while preventing direct contact with allergenic materials, thus maintaining grip performance without causing skin reactions
3Ease of operation
If pole length is reduced for storage, then storage convenience is improved, but structural stability may worsen
Solution Approach 1:
The ski pole incorporates a telescopic mechanism that allows the shaft length to be dynamically adjusted. The pole can be extended to full length for use, providing structural stability, and collapsed to reduced length for storage, maintaining stability through locked positions. This dynamic length adjustment resolves the contradiction between storage convenience and structural stability
Solution Approach 2:
The shaft is divided into multiple telescopic sections that can be independently positioned and locked. This segmentation allows the pole to maintain structural integrity at various lengths, providing stability when extended for use and compactness when retracted for storage, without compromising the overall structural composition
