Fur Processing Cover With Segmented Residue Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current apparatuses for processing the skin side of tubular fur face challenges in efficiently handling and removing residues, leading to complex solutions and insufficient removal, which results in maintenance issues and decreased scraping quality due to material sticking to moving parts.
Innovation Solution
The apparatus incorporates a cover that encloses the mandrel and scraping means, creating a controlled environment for residue collection and removal, using a pump or suction arrangement to manage residues at the bottom part, reducing the need for external separators and minimizing material contact with moving parts, thus enhancing maintenance efficiency and scraping quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover is introduced to enclose the mandrel and scraping means, then residue control and containment are improved, but device complexity increases
Solution Approach 1:
The cover is divided into a first cover part and a second cover part that can be separated from each other. This segmentation allows the cover to be assembled and disassembled easily for maintenance while still providing effective residue containment when closed, thus resolving the contradiction between reliability improvement and device complexity increase.
2Reliability
If external separators and suction arrangements are used, then residue removal is improved, but device complexity and cost increase
Solution Approach 1:
The invention extracts and eliminates the need for external separators and complex suction arrangements by designing the cover itself to perform the separation function through its geometry. The conical surface and bottom part of the cover create natural residue accumulation and removal paths, allowing the system to function with minimal external components while maintaining effective residue removal.
3Device complexity
If the apparatus operates without a cover, then device complexity is reduced, but material sticks to moving parts causing maintenance issues
Solution Approach 1:
The segmented cover design with separable first and second cover parts allows for quick access to internal components during maintenance. The cover can be opened to expose the mandrel and scraping means for cleaning, and the segmentation enables partial disassembly without removing the entire cover structure, thus reducing maintenance time while keeping the apparatus relatively simple.
4Reliability
If a closed cover system is used, then residue containment is improved, but ease of operation for maintenance decreases
Solution Approach 1:
The cover is segmented into separable first and second cover parts that can be easily detached from each other. This segmentation provides maintenance access to the internal components while maintaining effective residue containment during operation. The separable design allows operators to open the cover for maintenance without compromising the containment functionality when closed.
Solution Approach 2:
The cover design incorporates dynamic accessibility through its separable structure, allowing the system to transition between a closed state for residue containment and an open state for maintenance access. This dynamic capability resolves the contradiction between maintaining reliable residue containment and providing ease of operation during maintenance activities.
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
This configuration results in a more efficient and cost-effective processing of fur, reducing maintenance time, improving residue removal, and maintaining scraping quality by containing residues within the apparatus, thereby reducing the need for frequent cleaning and extending operational intervals.
Implementation Method 1
a suction arrangement (17) arranged to remove said material removed from said skin side through said suction opening in said cover (10)
Implementation Method 2
The apparatus comprises a pump arrangement connected to said outlet and being configured for pumping said material from said bottom part to the exterior of said cover
Implementation Method 3
Some of it may drip towards the lower part of the cover, and some of it may be hurled towards and stick to the inner surfaces of the cover. Over time, the material on the surface may thus, by means of e.g. gravity, be lead towards the bottom part of the cover to the outlet.
