Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing livestock watering systems face challenges in preventing water from freezing, especially in cold temperatures, as current methods like recirculating pumps and heating devices are inefficient and environmentally detrimental, and require complex mechanisms that are costly and unreliable.
Innovation Solution
A solar float device with a transparent upper shell and heat-conductive lower shell, containing a ballast material and energy-absorbing element, which absorbs solar radiation to generate heat and distribute it through the water, maintaining the device in an upright floating orientation to prevent freezing without the need for direct heating or complex mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If electrically or fossil fuel powered heating elements are used to heat water, then water freezing is prevented, but operational cost increases significantly and environmental harm increases
Solution Approach 1:
The device uses passive solar heating where the transparent upper shell allows sunlight to penetrate and heat the water directly, eliminating the need for external energy sources. The black-painted interior surfaces and dark ballast material absorb solar radiation and convert it to thermal energy, enabling the system to maintain water temperature above freezing without consuming electrical or fossil fuel energy.
Solution Approach 2:
The invention replaces active mechanical heating systems (electric heaters, propane heaters, recirculating pumps) with a passive thermal system based on solar radiation absorption. The transparent upper shell and heat-absorbing interior surfaces create a solar greenhouse effect that naturally heats the water, substituting mechanical energy conversion with optical-thermal energy conversion.
2Temperature
If recirculating pumps are used to prevent freezing, then water movement prevents freezing down to near-freezing temperatures, but the system becomes inadequate below 15-20 degrees Fahrenheit and requires additional heating equipment
Solution Approach 1:
The solar float device provides self-contained passive heating capability that operates independently without requiring pump systems or complex control mechanisms. The transparent upper shell and heat-absorbing materials work together to naturally heat water to temperatures above freezing through solar energy alone, eliminating the need for recirculating pumps and thermostatic controls.
3Loss of energy
If the water surface is covered to reduce heat loss, then heat loss from conduction, convection, and evaporation is reduced, but livestock cannot access the water directly
Solution Approach 1:
The device creates a localized heated zone on the water surface through the floating transparent shell, allowing livestock to access warm water directly at the surface without requiring full water surface coverage or mechanical opening mechanisms. The heat-absorbing interior surfaces concentrate solar heating in the immediate vicinity of the device, providing warm water access points throughout the tank.
4Ease of operation
If floating elements with openings are used to allow animal access, then animals can push elements down to access water, but the mechanism is mechanically complex and expensive and some animals cannot or will not operate it
Solution Approach 1:
The solar float device requires no operational interaction from livestock. The transparent upper shell remains continuously in place, providing both protection and heating, while animals can freely access water by pushing the device aside or through existing openings without needing to operate any mechanical components.

AI summary
A solar float device for use in a livestock watering facility to inhibit the freezing of water in a livestock watering facility. The solar float device having upper and lower shells that are connected to each other. The upper shell encloses an air space and the lower shell encloses a ballast space. A bulkhead is connected to the lower shell and separates the air and ballast spaces. A ballast material contained within the ballast space maintains the float device upright in the water and is thermally conductive for receiving and storing heat generated by the solar float device from solar radiation. An energy absorbing element contacts the lower shell and at least a portion is arranged either at or above the level of the water such that the energy absorbing element is exposed to the solar radiation for absorbing the solar radiation and converting the solar radiation into heat.
