Ski Run Tiller with Rotating Tracksetter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cross-country ski run apparatuses fail to consistently produce high-quality tracks and allow for high speed across various snowpack conditions due to limitations in adjusting the position of the tiller and tracksetting device.
Innovation Solution
An apparatus with a support structure, a first tiller, and a connection structure that allows the tracksetting device to freely rotate about an axis transverse to the advancing direction, independent of the tiller's position, enabling adaptable track formation across different snowpack conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the position of the main tiller is varied to adjust the tilling depth level in the snowpack according to snowpack characteristics, then the adaptability to different snowpack conditions is improved, but the quality of the tracks in the snow deteriorates because the tracksetting device cannot maintain its optimal position relative to the snowpack
Solution Approach 1:
The connection structure between the tiller and tracksetting device is made dynamically adjustable through articulated joints that allow free rotation about a transverse axis. This enables the tracksetting device to independently adjust its position relative to the snowpack while the tiller adjusts to snowpack conditions, resolving the contradiction between adaptability and track quality.
2Manufacturing precision
If the tiller position is fixed to maintain optimal track quality, then the manufacturing precision of tracks is improved, but the adaptability to varying snowpack conditions deteriorates
Solution Approach 1:
The apparatus is segmented into independently controllable components: the tiller for snowpack preparation and the tracksetting device for track formation. The connection structure allows these segments to operate independently, with the tiller adapting to snowpack conditions while the tracksetting device maintains its optimal position for track quality.
3Manufacturing precision
If the tracksetting device is rigidly connected to the tiller to maintain position, then the track quality is improved, but the speed of advancement deteriorates due to inability to adapt to varying snow conditions requiring repeated adjustments
Solution Approach 1:
The dynamic connection structure with articulated joints allows the tracksetting device to maintain optimal track quality while enabling rapid adaptation to varying snow conditions without requiring apparatus stopping or manual repositioning, thus maintaining high advancement speed.
