Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural equipment lacks the energy efficiency to macerate forage materials at the necessary speed and volume during harvesting, limiting the practicality of improving digestibility through extreme processing, which is crucial for optimizing nutrient absorption in ruminant animals.
Innovation Solution
A mechanical macerator equipped with a nutrition sensor, ration controller, and macerator sensor that adjusts the processing intensity based on the nutritive levels of the silage material to achieve optimal cell wall rupture and intracellular solubles release, thereby enhancing digestibility, and calculates the required amounts of other feed materials to create an optimized feed ration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If maceration is performed at high volume and speed to keep up with harvesting operations, then digestibility of forage material is improved, but energy consumption becomes too great for standard agricultural equipment to supply
Solution Approach 1:
The macerating mechanism uses adjustable rotor-stator clearance that can be dynamically modified based on forage characteristics. This allows the system to achieve effective maceration with variable energy input, optimizing performance for different crop types and maturity levels without requiring excessive energy consumption
Solution Approach 2:
The system changes operational parameters including rotor speed, stator configuration, and clearance distance to match the specific nutritive values and physical properties of the forage material. This parameter optimization enables effective maceration at lower energy consumption levels compared to fixed high-speed systems
2Quantity of substance
If extreme processing maceration is applied to all forage materials, then nutrient absorption is increased, but device complexity and operational complexity increase due to need for precise control
Solution Approach 1:
The system incorporates sensors that detect forage characteristics and provide feedback to the control system. This automated feedback loop adjusts maceration parameters in real-time based on actual forage properties, eliminating the need for complex manual control while ensuring optimal nutrient extraction
Solution Approach 2:
The macerating mechanism is designed to automatically adapt to different forage types through self-regulating features such as variable speed motors and adjustable clearances that respond to material properties. This self-adjusting capability reduces operational complexity while maintaining high nutrient absorption efficiency

Function Achieved in This Case
The mechanical macerator effectively increases the digestibility of silage materials by controlling the maceration process to match the nutritional needs of the animal, reversing the effects of plant maturity on fiber digestibility and optimizing feed production by determining the precise degree of maceration needed for specific forages.
Implementation Method 1
a nutrition sensor positioned relative to the macerating mechanism and operable to sense nutritive levels of the silage material
Implementation Method 2

AI summary
A method of preparing a feed ration (20) for an animal (22) includes storing a cut crop material in an accumulation having an oxygen barrier. The cut crop material is fermented within the accumulation to form a silage material (38). A nutritive value of the silage material (38) is determined with a nutrition sensor (58). A desired amount of maceration of the silage material (38) is determined based on the determined nutritive value of the silage material (38). The silage material (38) is then macerated with a mechanical macerator (40) to achieve the desired amount of maceration. The macerated silage material (38) is then combined with other feed materials (24) to define the feed ration (20), and may then be fed to the animal (22).
