Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skis lack the ability to adjust the position of the front contact point in a targeted and precise manner, limiting their adaptability to different skiing disciplines, user abilities, and varying environmental conditions.
Innovation Solution
A ski design featuring a ski binding with a tensioning device in the form of a cable and a sliding support that can be displaced along the ski's longitudinal axis, allowing precise adjustment of the contact point by changing the pivot point, thereby enhancing maneuverability and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed tensioning device is used in conventional skis, then the structure is simple, but the position of the front contact point cannot be adjusted precisely
Solution Approach 1:
The patent applies the dynamics principle by making the support movable along the longitudinal axis of the ski, allowing the front contact point position to be adjusted dynamically. The support can be positioned at different locations and fixed in place, enabling precise adjustment of the pivot point for the tensioning device. This dynamic positioning capability resolves the contradiction by providing adjustable precision without requiring a completely complex reconfiguration system.
Solution Approach 2:
The patent introduces a support as an intermediary element between the tensioning device and the ski body. This support acts as a mediator that can be positioned at different locations along the ski, thereby precisely controlling the pivot point of the tensioning device. The intermediary support simplifies the overall structure while enabling precise positioning, as it decouples the tensioning mechanism from direct attachment to the ski.
2Adaptability or versatility
If the front contact point position is fixed, then the manufacturing is simple, but the adaptability to different skiing conditions is limited
Solution Approach 1:
The movable support enables the ski to adapt to different skiing conditions by allowing adjustment of the front contact point position. Users can reposition the support along the longitudinal axis to optimize performance for various snow conditions, terrain types, and skiing disciplines. This dynamic adaptability is achieved without significantly complicating manufacturing, as the support system uses standard positioning mechanisms.
Solution Approach 2:
The patent implements universality by designing the support system to serve multiple functions: it acts as a pivot point for the tensioning device, a positioning mechanism for contact point adjustment, and an adaptation interface for different skiing conditions. This multi-functional design enhances versatility while maintaining manufacturing simplicity through standardized components.
3Measurement precision
If additional components are added to adjust contact point position, then the positioning precision improves, but the device complexity and material stress increase
Solution Approach 1:
The patent merges the positioning function and the tensioning pivot function into a single integrated support structure. By combining these functions, the design achieves precise contact point positioning without requiring separate adjustment mechanisms and pivot points. This merging reduces the overall number of components while maintaining high positioning precision.
Solution Approach 2:
The support structure serves multiple purposes: it provides the pivot point for the tensioning device, enables precise positioning of the front contact point, and acts as a mounting interface. This multi-functionality reduces the need for additional specialized components, thereby lowering device complexity while achieving precise positioning.

AI summary
The ski (1) has a ski connection (2) that is arranged at an upper side of a ski part (3) and a clamping device (4), which is extended from a range of an end of the ski connection up to an end range of the ski. A support (6) is arranged between the ski and the clamping device. The support is displaced along a longitudinal axis (L) of the ski such that a contact point of the ski is adjusted.
