Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cow magnets made of Aluminum Ni and Cobalt are toxic, causing health issues in cattle, while ferrite magnets, despite improvements, still raise concerns due to toxicity and structural weaknesses, leading to ineffective prevention of 'Hardware Disease' and potential harm to the bovine stomach.
Innovation Solution
A cow magnet made of Strontium Ferrite (SrFeO) with a non-toxic, healthy mineral composition, featuring a pole pattern that localizes metal fragments parallel to the magnet's length, minimizing stomach injury, and a pill shape to prevent passage into the intestines, ensuring strong magnetic properties and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AlNiCo alloy is used to make cow magnets, then the magnetic properties are adequate, but the magnet becomes toxic to cattle
Solution Approach 1:
The patent changes the chemical composition parameters by replacing AlNiCo alloy with SrFe12O19 ferrite material, which has different magnetic properties but eliminates the toxicity issue. The new material maintains sufficient magnetic strength while being non-toxic to cattle.
Solution Approach 2:
The patent uses a composite ferrite material SrFe12O19 that combines strontium and iron in a specific oxide structure. This composite material provides both the necessary magnetic properties and the non-toxic characteristic, resolving the contradiction between magnetic effectiveness and safety.
2Object-affected harmful factors
If ferrite magnets are used to replace AlNiCo, then toxicity is reduced, but structural weaknesses and manufacturing issues arise
Solution Approach 1:
The patent optimizes the sintering parameters and material composition to achieve the desired structural strength. By controlling the ferrite grain size, density, and phase composition during manufacturing, the material attains sufficient mechanical strength while maintaining its non-toxic properties.
3Reliability
If cow magnets are made with Barium Ferrite, then magnetic properties improve, but severe toxicity to cattle occurs
Solution Approach 1:
The patent changes the chemical composition by substituting barium with strontium in the ferrite structure. This parameter change maintains the magnetic properties needed for effective cow magnet function while eliminating the severe toxicity associated with barium ferrite.
Solution Approach 2:
The patent converts the potentially harmful barium ferrite material into a beneficial strontium ferrite material. By replacing the toxic element (barium) with a safer element (strontium), the same ferrite structure provides both magnetic functionality and safety, turning a harmful combination into a beneficial one.
4Ease of manufacture
If AlNiCo magnets are used, then manufacturing is straightforward, but the magnet causes health issues including bone diseases
Solution Approach 1:
The patent changes the material composition from AlNiCo alloy to SrFe12O19 ferrite, which eliminates the bone disease risk associated with aluminum and nickel. The manufacturing process for ferrite is well-established through sintering techniques, maintaining ease of production while improving safety.

AI summary
A cow magnet is provided having minerals that have been found useful for good health. A cow magnet of Ferrous Oxide (FeO) and stable Strontium (Sr) is discovered to be healthy. Stable Strontium (Sr) is discovered to be used by the bovine body to increase bone growth and strength. Iron (Fe) is known to be used by the bovine body for healthy red blood cells. The magnet is sintered to control the trace amounts of these elements released into the stomach. The polarity pattern is discovered for SrFe type magnets so that a nail will be held parallel to the length of the magnet and at the maximum strength. This pole pattern has been discovered to turn a nail parallel to the length of the magnet if the nail is placed on the magnet perpendicular to the length. This pole pattern also prevents a nail from being held along the length with the sharp tip sticking out past the end of the magnet. This prevents damage to the ruminator's first stomach. The strength is the same as the standard AlNiCo 5 magnets. The cost is less than AlNiCo magnets. The Aluminum in AlNiCo is discovered to be toxic. Therefore the Strontium Ferrous Oxide magnets (SrFeO) are more healthy.
