Ski Binding Base Plate Segmentation for Smooth Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety ski bindings experience tilting and reduced slidable movement due to high forces exerted by the ski boot, causing the supporting part to brace or get stuck in the guide profiles fixed to the ski.
Innovation Solution
The base plate is designed as an extension of the supporting part, running without contact with the ski's upper side and binding parts, ensuring that forces are transferred solely to the supporting part or housing, with optional elastic cushioning and recesses for optimal force transmission and self-support during high loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the ski boot is clamped between the sole holder and the base plate fixed to the ski, then the ski boot is securely held, but the supporting part braces in the guide profiles due to high forces, preventing smooth sliding movement
Solution Approach 1:
The base plate is divided into two separate components: the supporting part that slides in the guide profiles and the base plate proper that contacts the ski boot. This segmentation allows the clamping function to be separated from the sliding function, enabling smooth movement while maintaining secure clamping.
Solution Approach 2:
A stand plate is introduced as an intermediary element between the base plate and the ski boot. This stand plate absorbs and distributes the forces from the ski boot, preventing them from being transmitted directly to the supporting part in the guide profiles, thus avoiding bracing while maintaining clamping strength.
2Stability of the object's composition
If the base plate is firmly connected to the ski to provide stability, then the binding is stable, but the supporting part cannot slide freely in the guide profiles under load
Solution Approach 1:
The base plate is segmented into a supporting part for sliding and a base plate portion for stable mounting. The supporting part is designed to slide freely in the guide profiles while the base plate is firmly connected to the ski, separating the stability function from the movement function.
Solution Approach 2:
The stand plate acts as a mediator that allows the base plate to be firmly connected to the ski while preventing force transmission to the supporting part. This intermediary element enables stable mounting without restricting the sliding movement of the supporting part in the guide profiles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design prevents undesired tensioning of the supporting part in the guide profiles, allowing smooth sliding even under large forces, enhancing the ski binding's functionality and reliability.
Implementation Method 1
the base plate is made in one piece with the support part or is firmly connected to it... running without contact with respect to the upper side of the ski and other binding parts

AI summary
The ski binding jaw has a housing (1) arrangeable at or in ski-fixed guide profiles (5) in a ski-longitudinal direction by a support part in a sliding manner. A frame plate (7) is implemented with the support part or the housing in a single-piece manner or is connected with the support part or the housing in a fixed manner, where the frame plate is arranged in such a manner that a force acting on the frame plate from an ski boot is transferred onto the support part or the housing entirely or in large parts.
