Sleeve-Coupling Slot Design for Secure Poultry Plucker Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing poultry feather plucking devices require complex constructions and auxiliary instruments for secure mounting and dismounting on drive-shafts, complicating the process and increasing the risk of accidental displacement.
Innovation Solution
The device features a sleeve-coupling with a circumferentially extending slot for a radially extending pin on the drive-shaft, allowing secure and balanced mounting, and a recess with a slope for easy dismounting, potentially utilizing magnetic materials for enhanced security and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complicated construction with opposing side clamps and locking bolt recesses is used to secure the device to the drive-shaft, then the secure mounting is improved, but the device complexity increases and auxiliary instruments are required for mounting and dismounting
Solution Approach 1:
The invention extracts the mounting and dismounting function from the main device body by using a separate sleeve-coupling component. This allows the device to be easily attached to and removed from the drive-shaft without requiring complex clamps or auxiliary tools, resolving the contradiction between secure mounting and device complexity
Solution Approach 2:
Instead of using a locking mechanism that requires tools to engage and disengage, the invention inverts the approach by using a slot-extremity design where the pin naturally engages at one extremity for secure mounting and can be easily released by pushing at the opposite extremity. This eliminates the need for auxiliary instruments while maintaining secure attachment
2Reliability
If a complicated construction with opposing side clamps is used to secure the device to the drive-shaft, then the secure mounting is improved, but the ease of operation deteriorates due to requirement of auxiliary instruments
Solution Approach 1:
The sleeve-coupling design allows the device to be mounted and dismounted without auxiliary instruments. The pin engages automatically when brought to the slot, and can be released by simple manual manipulation at the slot-extremity opening, making the operation self-service and eliminating the need for additional tools
Solution Approach 2:
The invention inverts the traditional locking mechanism by placing the opening at the slot-extremity opposite to the engagement side. This allows the pin to be easily pushed through from the opening side for quick dismounting, while still maintaining secure engagement when the pin is at the other extremity, thus improving ease of operation without compromising mounting security
3Ease of manufacture
If the sleeve-coupling edge thickness is uniform, then the manufacturing is simplified, but the secure mounting is reduced compared to variable thickness design
Solution Approach 1:
The sleeve-coupling edge is designed with variable thickness where specific regions (such as near the slot-extremity opening) are thicker to provide structural strength and secure mounting, while other regions are thinner to reduce material usage and simplify manufacturing. This local quality differentiation resolves the contradiction between ease of manufacture and secure mounting

AI summary
Device for picking or plucking poultry-feathers comprising a sleeve-coupling (7) and connected or connectable thereto a plucking plate (2) with receptacles (3) for plucking fingers, which sleeve-coupling is mountable on a drive-shaft for the plucking plate. The sleeve-coupling is provided with a circumferentially extending slot (8) for receipt of a radially extending pin (9) that is provided on the drive-shaft (6), and that the circumferentially extending slot has an opening (10) between the slot-extremities (8',8'') to allow said pin to enter and to exit. the slot, so as to cause that. with the pin being located at one of the slot-extremities the sleeve-coupling is securely mounted on the drive-shaft.
