Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for cleaning animal carcasses before hide removal are inadequate in removing organic material and pathogens, often requiring high volumes of water and lacking effective mechanical action.
Innovation Solution
A hide-on washer apparatus with multiple rotating devices mounted on a frame, featuring radially extending strand elements that physically scrub the carcass with water and chemicals, positioned at various angles and elevations to ensure thorough cleaning while conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional high-volume water washing is used, then water flow is increased, but cleaning effectiveness is insufficient
Solution Approach 1:
The patent replaces the conventional hydraulic washing system with a mechanical scrubbing system. Rotating brushes with bristles mechanically scrub the carcass surface, providing effective cleaning action that water alone cannot achieve. This mechanical substitution resolves the contradiction by delivering superior cleaning effectiveness without relying on high water volumes.
Solution Approach 2:
The patent changes the cleaning mechanism from fluid-based to solid-contact-based. By introducing rotating brushes with varying bristle hardness and rotation speeds, the system transforms the cleaning approach to achieve better results with reduced water consumption, directly addressing the effectiveness-volume contradiction.
2Stress or pressure
If high pressure water is used, then water pressure is increased, but organic material removal is insufficient
Solution Approach 1:
The patent substitutes high-pressure water jets with mechanical brush scrubbing. The rotating brushes physically contact and scrub the carcass surface, providing the mechanical force needed to remove organic material and pathogens that pressurized water cannot effectively eliminate.
Solution Approach 2:
The cleaning system uses composite brush assemblies combining different bristle materials and hardness levels. This composite approach allows the brushes to effectively remove various types of organic contamination through mechanical action, surpassing the capabilities of pressurized water alone.
3Reliability
If mechanical scrubbing is added, then cleaning effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent divides the cleaning system into multiple independent brush stations, each with specific functions. The carcass passes through a sequence of brushing zones with different brush characteristics, allowing effective cleaning without requiring an overly complex monolithic design. This segmentation manages device complexity while maintaining high cleaning effectiveness.
Solution Approach 2:
The patent employs dynamically adjustable brush systems where rotation speeds and brush positions can be modified. This dynamic capability allows the system to adapt to different cleaning requirements without permanent complex configurations, balancing effectiveness with manageable device complexity.
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
The apparatus effectively removes organic and foreign matter from carcasses, improving hygiene and reducing water and chemical usage, thereby enhancing the cleaning process beyond conventional methods.
Implementation Method 1
The mechanical action and the contact of the strand elements that physically strike the carcass as the rotating devices rotate, together with an application of water, cooperate to clean the carcass
Implementation Method 2
the strand elements that physically strike the carcass as the rotating devices rotate
Implementation Method 3
together with an application of water, cooperate to clean the carcass. More particularly, the strand elements, together with water under pressure or a combination of water under pressure and chemicals, remove unwanted organic and foreign matter

AI summary
An apparatus for cleaning a carcass includes an elongate housing having a forward and a rearward frame disposed in parallel, transversely opposed relation to one another. The elongate housing includes a plurality of stations. At least one rotating device at each station is disposed on the forward or rearward frame. A first station may include a pair of transversely opposed counter-rotating devices disposed at a common downward angle relative to a longitudinal axis of the elongate housing. A second station includes a plurality of rotating devices positioned near the top of the apparatus to clean the hoof and ankle area. A third station includes a plurality of vertically stacked rotating devices. A fourth, fifth, and sixth station include plural rotating devices in axial alignment with one another that are collectively oriented in a predetermined downward slope relative to the longitudinal axis to clean a carcass from top to bottom.
