Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current snowmaking systems for alpine ski areas face challenges in accessing and efficiently diverting water from high-elevation sources like mountain springs, streams, and aquifers due to remote locations, freezing conditions, and lack of access to AC power, leading to high energy costs and environmental impact.
Innovation Solution
A modular water distribution system comprising a water diverter unit and flow regulation unit that can divert and regulate water from remote, high-elevation sources without AC power, using wireless control and local power generation, and includes features like turbine generators and insulated components to operate in freezing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water is diverted from high-elevation sources using traditional pumping systems, then water can be delivered to snowmaking equipment, but energy consumption increases and greenhouse gas emissions rise
Solution Approach 1:
The system uses the natural flow of water from high-elevation sources to generate electricity through a turbine generator, making the water flow serve dual purposes: both delivering water to snowmaking equipment and generating power to operate the diversion system, thereby eliminating external energy consumption
Solution Approach 2:
The system exploits the gravitational potential energy of water at high elevations by allowing it to flow downhill naturally through pipes to lower elevations, converting potential energy to kinetic energy to drive the turbine generator and deliver water without requiring additional pumping energy
2Ease of operation
If AC power is used to control water diversion valves in remote locations, then precise water distribution is achieved, but environmental impact and operational costs increase
Solution Approach 1:
The system replaces AC-powered electronic control systems with a wireless control mechanism powered by a turbine generator that converts the kinetic energy of flowing water into electrical energy, eliminating the need for external AC power infrastructure in remote locations and reducing greenhouse gas emissions
Solution Approach 2:
The turbine generator serves multiple functions: it generates electricity to power the wireless control system for water diversion valves, and its operation is entirely dependent on the natural water flow, creating a self-sustaining system that reduces environmental impact while maintaining operational control
3Productivity
If water pipes are exposed in freezing conditions, then water flow is maintained, but pipes freeze and system functionality is lost
Solution Approach 1:
The system changes the temperature parameter of the water by using the kinetic energy of flowing water to drive a turbine generator that produces electricity, and the constant flow of water prevents freezing by maintaining movement and preventing ice crystal formation in the pipes
Solution Approach 2:
The system maintains continuous water flow through the pipes from high-elevation sources to snowmaking equipment, ensuring that water is always moving rather than stagnant, which prevents freezing in exposed pipes and maintains system reliability in freezing conditions
4Productivity
If water is pumped uphill from low-elevation sources, then water can reach snowmaking equipment, but energy costs increase
Solution Approach 1:
Instead of pumping water uphill from low-elevation sources, the system inverts the approach by capturing water at high-elevation sources and allowing it to flow downhill naturally, using the gravitational force to deliver water to snowmaking equipment without requiring energy-consuming pumps

AI summary
A water gathering and distribution system and related techniques for operating in freezing environmental conditions are disclosed. The system may include a water diverter unit or a water flow regulation unit configured to receive water from a water source situated at a location that is remote, inaccessible (or difficult to access), and/or experiences freezing environmental conditions and to deliver a controlled volume of that water for downstream use. The system further may include a water supply unit configured to receive that water and to supply it to downstream snowmaking equipment. In some instances, the supply unit also may cool the water to a temperature suitable, for example, for snowmaking. In a general sense, the disclosed system may be considered modular, in that multiple system components may be placed in flow communication with one another, as desired, to provide a distributed network of water collection and distribution elements.
