Adjustable Crampon Coupling for Ski and Hiking Boot Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crampons are not suitable for both ski mountaineering and mountaineering boots, leading to clearance issues, reduced stability, and potential snow or ice entry, compromising safety and functionality.
Innovation Solution
A crampon design with a connecting element that can take two configurations, allowing optimal coupling to both ski mountaineering and hiking boots, featuring adjustable and interchangeable components for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the crampon is designed with a fixed configuration for ski mountaineering boots, then it provides stable attachment for that specific boot type, but it creates clearance issues and reduces adhesion when used with mountaineering boots
Solution Approach 1:
The crampon frame incorporates adjustable connection elements that allow the distance between front and rear portions to be modified. This dynamic adjustment capability enables the crampon to adapt its geometry to match different boot sole configurations, eliminating clearances and ensuring optimal adhesion whether used with ski mountaineering boots or mountaineering boots
Solution Approach 2:
The patent implements longitudinal adjustment elements with multiple positioning holes that allow users to change the distance parameter between front and rear frame portions. By adjusting this parameter, the crampon can be configured to match the specific longitudinal dimensions of different boot types, thereby maintaining reliable attachment across varied applications
2Reliability
If additional stabilization elements are added to the crampon, then adhesion to the boot is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The crampon is divided into front and rear portions that can be independently adjusted and positioned. This segmentation allows each portion to be optimized for its specific function while maintaining overall simplicity, avoiding the need for complex additional stabilization elements
Solution Approach 2:
The adjustable connection elements serve multiple functions: they provide structural connection between frame portions, enable longitudinal adjustment for different boot types, and ensure proper alignment. This multi-functionality eliminates the need for separate stabilization components, maintaining device simplicity while achieving reliable adhesion

AI summary
A crampon for ski mountaineering, mountaineering, or hiking boots includes a frame with front and rear portions connected by a longitudinal connecting rod, wherein the front portion includes retention elements and a support surface with a first coupling seat oriented at an angle relative to the crampon's axis, and the connecting rod includes at least one selector extending along an axis forming an angle with the crampon axis, such that by matching the angles of the selector and the coupling seat, the crampon can be configured for either a ski mountaineering boot or a mountaineering/hiking boot, thereby enabling optimal fit and secure attachment for different boot types.
