Solution Overview
Problem
Existing cross-country ski trail marking devices are expensive to manufacture, require high energy input, and are not easily adaptable to varying snow conditions, leading to inefficient trail preparation and high energy consumption.
Innovation Solution
A device with selectively positioned ripping devices and a milling device, where each ripping device is assigned to a track body, allowing precise subsoil tearing and minimal energy expenditure, and a milling device with adjustable engagement depth to process only the necessary area, reducing unnecessary processing and energy requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple ripping devices are used to break up the snow surface, then the substrate is effectively prepared for track marking, but the energy consumption and device complexity increase
Solution Approach 1:
The device divides the snow preparation function into separate ripping devices and a milling device, with each ripping device assigned to a specific track body. This segmentation allows targeted substrate preparation only where needed, reducing unnecessary energy consumption while maintaining effective snow breakdown for track marking.
Solution Approach 2:
Each ripping device is selectively positioned and assigned to process only the substrate area corresponding to its associated track body. This local quality approach ensures that energy is expended only in the necessary areas for track preparation, rather than uniformly across the entire working width, thereby reducing overall energy consumption while achieving adequate substrate preparation.
2Manufacturing precision
If extensive mechanical processing of snow is performed, then the cross-country ski track quality is improved, but the drive power and pulling power requirements increase
Solution Approach 1:
The mechanical processing function is segmented into ripping devices for initial snow breakdown and a milling device for final track formation. This segmentation allows the milling device to work on pre-loosened snow, reducing the power required for milling while maintaining high track quality through the combined action of ripping and milling.
Solution Approach 2:
The ripping devices perform preliminary action by breaking up and loosening the snow substrate before the milling device creates the final track. This preliminary loosening of the snow reduces the resistance encountered by the milling device, thereby reducing the drive power and pulling power needed while still achieving high-quality track preparation.
3Manufacturing precision
If the ripping device processes the entire track width, then complete substrate preparation is achieved, but the energy required increases and the device becomes less adaptable to varying snow conditions
Solution Approach 1:
The ripping function is segmented into multiple independently controllable ripping devices, each assigned to a specific track body. This segmentation allows the system to adapt to varying snow conditions by selectively activating or adjusting individual ripping devices based on local substrate conditions, while still achieving complete preparation coverage across the entire track width.
Solution Approach 2:
The ripping devices are selectively positionable and can be independently adjusted to accommodate varying snow conditions. This dynamic capability allows the device to adapt its ripping pattern and intensity to match local substrate conditions, improving versatility while maintaining complete substrate preparation coverage through coordinated operation of multiple ripping devices.
