Movable Ski Binding Anti-Slip Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-slip devices for skis are ineffective on icy surfaces and impair forward sliding, requiring surface and temperature-dependent solutions.
Innovation Solution
A ski design with a movable binding part and mandrel system that activates anti-slip protection during push-off and deactivates when gliding, using a spring-loaded mechanism to position the mandrel for optimal engagement with the snow or ice, ensuring effective anti-slip on various conditions without hindering forward motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-slip devices (scales, grip wax, skins) are applied to the ski, then backward sliding is prevented to some extent, but forward gliding is impaired and effectiveness on icy ground is insufficient
Solution Approach 1:
The pin is made movable rather than fixed, allowing it to dynamically change position between retracted (during forward gliding) and extended (during backward sliding prevention). The binding part's displacement relative to the ski base body automatically controls the pin's position, enabling the anti-slip device to adapt its state based on the skier's movement phase.
Solution Approach 2:
The anti-slip function is separated from the gliding surface by using a distinct pin element that can be independently controlled. The pin acts as a separate anti-slip component that engages only when needed, while the gliding surface remains clean and effective for forward motion.
2Adaptability or versatility
If conventional anti-slip devices are applied, then some backward sliding prevention is achieved, but the devices are ineffective on icy ground and depend heavily on ground conditions and temperature
Solution Approach 1:
The pin's physical state changes from retracted to extended based on the binding part's position parameter. This parameter change allows the anti-slip mechanism to engage with the ground in a controlled manner, providing reliable traction on icy surfaces where conventional devices fail.
3Reliability
If a fixed anti-slip structure is used, then backward sliding is prevented, but the structure adds complexity and cannot be activated/deactivated as needed
Solution Approach 1:
The system uses the skier's own movement (binding part displacement) to automatically control the anti-slip mechanism. The binding part's relative displacement self-activates the pin extension during push-off and self-retracts it during forward gliding, eliminating the need for external control systems or complex mechanisms.
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
The ski provides intuitive and effective anti-slip protection on icy surfaces while maintaining smooth forward sliding, with the mandrel system engaging the ground only during push-off to prevent backward sliding, thus enhancing skiing performance across different conditions.
Implementation Method 1
The pin is positioned in the retracted position by means of a spring
Implementation Method 2
The control surface interacts at least indirectly with the pin in such a way that when the binding part is moved relative to the ski base body from the first, front sliding position to a second, rear sliding position, for example during a push-off movement of the skier, the pin is positioned in a pushed-forward position
Implementation Method 3
the pin is positioned in a pushed-forward position in which the free end protrudes beyond the sliding surface in order to thereby prevent the ski from sliding backwards during the push-off movement by engaging with the ground

AI summary
The invention relates to a ski comprising a ski main body (2) having a sliding surface (3) and a binding part (4) to which a skier's boot can be fastened, wherein the binding part (4) is fixed on the ski main body (2) so as to be movable in the longitudinal direction (LR), wherein at least one control surface (5) which interacts at least indirectly with at least one spike (6, 6') that is movably mounted in the ski main body (2) is provided on the binding part (4) or on a functional part connected to the binding part (4), and wherein the spike (6, 6'), in a first, forward push position of the binding part (4), is positioned in a pushed-back position in which the free end (6.1, 6.1') of the spike (6, 6') does not project beyond the sliding surface (3), and the control surface (5) interacts at least indirectly with the spike (6, 6') in such a way that when the binding part (4) is moved relative to the ski main body (2) during a push-off movement of the skier, the spike (6, 6') is positioned in a pushed-forward position in which the free end (6.1, 6.1') projects beyond the sliding surface (3).
