Ski Jump Track Thermal Decoupling via Segmented Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ski facility devices face challenges in compensating for temperature fluctuations and thermal expansion, as receptacles for snow or ice are firmly connected to a carrier plate, making it difficult to manage length changes and thermal separation from the subsurface.
Innovation Solution
A device with parallel, offset components connected by a side wall and supported by elements on the substructure, allowing for thermal decoupling and better compensation of length changes, featuring temperature control modules, sensors, and fluoropolymer sliding elements for year-round operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If receptacles for snow or ice are firmly connected to a carrier plate, then structural stability is improved, but thermal expansion compensation deteriorates
Solution Approach 1:
The device is divided into separate components: the substructure, the component with receptacles, and support elements. This segmentation allows the receptacles to be thermally decoupled from the substructure while maintaining structural stability through the support elements.
Solution Approach 2:
The support elements act as intermediaries between the substructure and the component. They provide mechanical support while thermally decoupling the component from the substructure, enabling both structural stability and thermal expansion compensation.
2Ease of manufacture
If receptacles are thermally connected to the ground, then installation simplicity is improved, but thermal decoupling deteriorates
Solution Approach 1:
The support elements serve as thermal intermediaries that are spaced from the substructure, creating thermal barriers while maintaining mechanical support. This allows the component to be thermally decoupled from the ground.
Solution Approach 2:
The support elements are designed with spacing from the substructure, creating thermal insulation gaps that prevent direct thermal contact while maintaining structural support.
3Area of stationary object
If winter and summer lanes are arranged alternately, then space utilization is improved, but lane width requirements increase
Solution Approach 1:
The device utilizes the vertical dimension by arranging winter and summer lanes at different heights. The component is offset from the substructure, allowing alternating lanes to be positioned at different elevations, thereby reducing horizontal space requirements.
Solution Approach 2:
The alternating lanes are nested vertically within the same horizontal footprint. The component structure allows one lane to be positioned above another, effectively nesting the winter and summer routes in the vertical dimension.
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
Enables all-year-round use of ski facilities without conversion, reduces space requirements, and maintains consistent running surface characteristics between winter and summer, with improved sliding properties and reduced ice formation.
Implementation Method 1
temperature control modules can also be arranged in the substructure and/or on the component, so that a constant temperature of the routes can be set
Implementation Method 2
In order to reduce or completely prevent the formation of ice on the underside of the component, the component can be heated by the tempering modules on the substructure and/or the underside of the component
Implementation Method 3
The snow or ice in the device can be cooled with the aid of the temperature control modules
Implementation Method 4
A disadvantage is seen in the fact that the receptacles for snow or ice and/or for sliding elements are firmly connected to a carrier plate, which means that expansions caused by temperature fluctuations can only be compensated for with difficulty
Implementation Method 5
particularly good sliding properties can be achieved if the component and/or the sliding elements and/or the roadway limiting devices consist of fluoropolymers

AI summary
The invention relates to a device for a ski facility, in particular a ski jump facility or cross-country skiing course, which has a substructure and at least one track for winter/summer operation. The object of the invention is to create a device that can better compensate for different length changes, in particular at the temperature differences between summer and winter, and permits substantial thermal separation between undersoil and the holders for snow and ice and/or for slide elements. According to the invention, this is achieved by the fact that a structural part that has surfaces which are offset vertically approximately parallel to the substructure and are connected to one another by at least one side wall is operatively connected to support elements arranged on the substructure and is arranged at a distance from the substructure.
