Removable Elastic Return Element for Nordic Ski Boots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Nordic ski boot connecting devices with elastically deformable elements wear out quickly, posing reliability and maintenance issues, especially in competitive equipment, as these elements are not easily replaceable.
Innovation Solution
A Nordic ski boot with a connecting device featuring a removable support element for the elastic return mechanism, allowing for interchangeable elastically deformable elements that can be secured to the sole, providing adjustable hardness, stiffness, and geometry based on skiing conditions and type of binding used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastically deformable elements are integrated into the connecting device, then the boot can be dynamically recovered vertically, but these elements wear out quickly and cannot be replaced
Solution Approach 1:
The patent divides the connecting device into separable components: the elastic element is made as an independent replaceable part that can be detached from the support structure. This segmentation allows the elastic element to be replaced without replacing the entire connecting device, resolving the contradiction between durability and replaceability.
Solution Approach 2:
The elastic element is extracted from the integrated connecting device structure and made into a separate, removable component. This extraction enables the elastic element to be independently replaced when worn, while the main connecting device structure remains intact and reusable.
2Ease of operation
If elastically deformable elements are made from flexible elastomer material, then vertical dynamic recovery is achieved, but frequent replacement is required
Solution Approach 1:
The patent enables changing the properties of the elastic element by allowing replacement with different elastomer materials having varying hardness, elasticity, and durability parameters. This parameter change capability allows optimization of both the dynamic recovery function and service life based on specific usage requirements.
3Stability of the object's composition
If the connecting device is fixed to the shoe sole, then stable connection is provided, but modification and replacement of components becomes difficult
Solution Approach 1:
The patent introduces a dynamic, adjustable aspect to the previously fixed connecting device. The elastic element is designed to be replaceable, allowing the system to adapt to different conditions and requirements while maintaining stable connection during use. This creates a dynamic system that can be customized for different applications.
