Ski Pole Basket with Rotating Joint for Slope Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole baskets fail to adapt effectively to different slopes and snow conditions, leading to reduced power transmission and uncontrolled contact with the ground, as they either become stiff and brittle in cold temperatures or lack flexibility.
Innovation Solution
A pole basket designed with a rigid disk that can freely rotate and tilt around two axes, utilizing a joint with sliding or rolling elements to provide flexibility without material deformation, allowing adaptation to slopes and improved power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible material (thermoplastic) is used for the pole basket, then the pole basket can adapt to ground incline, but it becomes stiff and brittle at low temperatures and loses flexibility
Solution Approach 1:
The pole basket is divided into multiple independent elements (first element, second element, third element) that can move relative to each other. This segmentation allows the basket to adapt to ground inclines through relative movement of segments while each segment maintains its structural integrity and flexibility in cold temperatures.
Solution Approach 2:
The pole basket transitions from a static structure to a dynamic one where elements can move relative to each other. The basket includes movable connections that allow adaptation to slopes while maintaining controlled contact with the ground, enabling the structure to dynamically adjust to terrain variations without becoming brittle.
2Adaptability or versatility
If soft flexible material is used for the pole basket, then the pole basket can adapt to slopes, but power transmission is reduced and contact with ground becomes uncontrolled
Solution Approach 1:
The basket is segmented into multiple elements with different characteristics. The first element provides stable ground contact for power transmission, while the second and third elements provide flexibility for slope adaptation. This segmentation allows simultaneous achievement of controlled force transmission and slope adaptability.
Solution Approach 2:
Different elements of the basket have different local properties optimized for specific functions. The first element has properties optimized for stable contact and power transmission, while other elements have properties optimized for flexibility and slope adaptation. Each local region has the quality needed for its specific function.
3Force
If rigid material is used for the pole basket, then power transmission is improved, but the pole basket cannot adapt to ground incline
Solution Approach 1:
The rigid power transmission structure is segmented into multiple elements that can move relative to each other. This allows the overall structure to maintain rigidity for effective power transmission while individual segments can adjust to adapt to ground inclines through relative movement.
Solution Approach 2:
The pole basket incorporates dynamic elements that allow a predominantly rigid structure to adapt to slopes. The rigid elements maintain structural integrity for power transmission, while movable connections between elements enable adaptation to ground inclines through controlled movement.
4Adaptability or versatility
If interchangeable plates of different sizes are attached to the ski pole, then adaptability to different snow conditions is improved, but device complexity increases
Solution Approach 1:
The pole basket elements are designed to be universally applicable and interchangeable. The first element can function as a standalone basket or combine with second and third elements for different conditions. This multi-functionality provides adaptability to various snow conditions without requiring complex specialized attachment mechanisms for each configuration.

Implementation Method 1
The joint has two opposing, axially offset joint sleeves on the pole holder and two opposing, circular joint disks arranged on the inner plate, with at least one of the two joint sleeves having a circumferential annular groove open in the direction of the opposite joint sleeve
