Dry Snow Grass Sliding Blanket for Safe Skiing Landings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dry snow landing ramps for skiing and kitesurfing are seasonally restricted, unsafe, and do not allow for complete 'sports leap' actions due to limitations in air cushion water spraying technology, which results in high water and energy consumption and inability to resist cold temperatures.
Innovation Solution
A landing ramp design featuring an inclined ramp with a granule retaining dam and deceleration ramp, covered with a dry snow grass sliding blanket and dry snow granule layer, utilizing helical support columns for improved damping and stability, and a system for collecting and reusing dry snow granules to maintain a stable landing surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air cushion water spraying technology is used, then safety of the leaper is ensured, but the leaper cannot finish complete sports leap action and cannot continue to slide after leaping
Solution Approach 1:
The patent changes the physical state and properties of the landing surface from a water-sprayed air cushion to a granular material system. The granular material can be adjusted in terms of particle size, shape, and composition to provide both safety and the ability to support complete sports leap actions, including sliding continuation
Solution Approach 2:
The patent uses composite granular materials that combine different properties - some particles provide cushioning for safety while others provide friction and grip for sliding. The combination of granular materials with different characteristics allows simultaneous achievement of safety and sports leap completion
2Ease of operation
If air cushion water spraying is used, then landing is possible, but water and electricity consumption is high and manual real-time control is required
Solution Approach 1:
The granular material system is self-regulating and does not require external power or water supply. The granules automatically adjust to provide cushioning and support without needing inflation, deflation, or water spraying systems, eliminating continuous energy consumption
Solution Approach 2:
The patent extracts and eliminates the complex water spraying and air cushion inflation systems from the landing ramp design. By removing these energy-consuming subsystems and replacing them with passive granular material, the system achieves landing functionality without high water and electricity consumption
3Object-generated harmful factors
If uniform water spraying on large area air cushion is implemented, then landing is enabled, but it consumes a lot of water and requires manual real-time control
Solution Approach 1:
The granular material acts as a disposable-like system in the sense that it can be easily replaced or replenished. Individual granules undergo deformation and can be considered short-living individual units, but the overall system is sustainable through simple refilling rather than continuous water consumption
4Object-affected harmful factors
If the leaper is completely damped with sprayed water, then landing cushioning is achieved, but the damp leaper cannot resist against the cold in spring and autumn
Solution Approach 1:
The patent changes the medium from liquid water to solid granular material. This parameter change allows the landing surface to provide cushioning through granular deformation rather than liquid damping, preventing the leaper from becoming wet and vulnerable to cold temperatures in transitional seasons
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 safe and complete 'sports leap' actions without seasonal restrictions, reduces energy consumption, and prolongs the service life of the ramp by providing a stable and flat landing surface, while also reducing the risk of injury and environmental impact.
Implementation Method 1
the dry snow granule layer laid on the inclined ramp can roll down freely from the upper end of the inclined ramp under the gravity of the dry snow granule
Implementation Method 2
the plurality of dry grass bodies are arranged at intervals, an aperture of meshes on the mounting mesh plate is smaller than a diameter of a dry snow granule
