Ski Binding Anchor Design for High Triggering Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern ski bindings face a conflict between achieving high triggering forces and maintaining a lightweight, filigree design, as the release force needs to be stronger for advanced skiers while ensuring the structural integrity of the binding components.
Innovation Solution
A shoe holding element with a base plate connected to a ski, featuring a T-shaped anchor that securely engages with the shoe-retaining element housing, allowing for adjustable release forces up to 20, which are introduced through a spring element and adjustment mechanism, ensuring high triggering forces without deforming the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the release force is increased for advanced skiers, then the reliability of the binding is improved, but the structural integrity of the housing may be compromised
Solution Approach 1:
The patent divides the force transmission path into separate components: the anchor (made of metal or reinforced plastic) handles the high triggering forces, while the plastic housing maintains its lightweight structure. This segmentation allows each component to be optimized for its specific function without compromising overall performance.
Solution Approach 2:
The patent employs composite construction by combining metal or reinforced plastic anchor components with a plastic housing. This allows the binding to achieve both high strength where needed (anchor) and lightweight construction where possible (housing), resolving the contradiction between strength and weight.
2Reliability
If the release force is increased to prevent false releases, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent simplifies the overall structure by segmenting the force application mechanism. The anchor directly transmits forces to the housing through defined attachment points, eliminating the need for complex intermediate mechanisms while maintaining reliable high release forces.
3Strength
If metal components are used to handle high forces, then the strength is improved, but the weight of the binding increases
Solution Approach 1:
The patent applies local quality by using metal or reinforced plastic only for the anchor components that require high strength, while the housing and other non-critical parts remain in lightweight plastic. This localized use of strong materials minimizes weight while maintaining necessary strength.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the setting of very high triggering forces necessary for professional skiing without compromising the structural integrity or weight of the binding, allowing for safe and reliable release of the ski boot.
Implementation Method 1
The device has an anchor 6 which can be subjected to tensile stress and by means of which the set triggering force is introduced, preferably directly, into the shoe-retaining element housing 5 or base 2

AI summary
The element (1) has a base board (2) connected with a ski. Shoe holding element housing (3) is connected with the base board. A sole holder (4) is utilized for releasable holding of a ski boot on the ski. A metal adjusting device (5) is utilized for adjustment of release force of the shoe support element, and comprises a train on-duty anchor (6). The anchor is anchored in or on the shoe holding element housing. An auxiliary lever is connected with a joint of an opening lever (11) and another joint with the connecting device.
