Mammal Jacketing Tube with Conical-Cylindrical Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for putting a jacket on small mammals, such as those used in laboratories, require restraining or anesthetizing the animals, causing stress and discomfort.
Innovation Solution
A device comprising a tube with a conical and cylindrical part, a slit, and a base that allows the mammal to pass through, engaging the jacket as it exits, facilitating easy placement without restraint or anesthesia, along with a method involving vertical and horizontal positioning of the device to guide the mammal into the jacket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional methods are used to put a jacket on small mammals, then the jacket can be secured on the animal, but the animal must be restrained or anesthetized causing stress and time loss
Solution Approach 1:
The patent introduces an intermediary device (the tube with conical-cylindrical structure) that mediates between the operator and the animal. The animal voluntarily enters the tube as an intermediary space, and the jacket is already positioned on the tube, eliminating the need for direct restraint or anesthesia during jacket application.
Solution Approach 2:
The jacket is preliminarily positioned on the tube before the animal enters. The conical-cylindrical tube is prepared in advance with the jacket secured to its outer surface, so that when the animal passes through, the jacket is already in place, eliminating the need for restraint during the actual jacketing process.
2Ease of operation
If restraining or anesthetizing is used to place the jacket, then the jacket placement can be completed, but time is lost and stress is generated
Solution Approach 1:
The animal itself performs the action of entering the tube and allowing jacket placement without external restraint. The voluntary entry of the animal into the pre-prepared tube system enables self-service jacket placement, eliminating time-consuming restraint and anesthesia procedures.
3Object-affected harmful factors
If a jacket is placed on a small mammal without restraint, then stress is reduced, but the jacket may not stay in position
Solution Approach 1:
The tube features a conical-cylindrical curved geometry that naturally guides and contains the animal. The conical section tapers to guide the animal in, while the cylindrical section provides a stable curved surface for jacket placement, using geometry to ensure both animal comfort and jacket stability without restraint.

AI summary
A device for putting a jacket on a mammal, comprising: a tube extending along an axis between an inlet and an outlet; the tube comprising: a hollow conical part tapering from the inlet and a hollow cylindrical part contiguous to the conical part and leading to the outlet, the cylindrical part having an outer surface adapted to receive the jacket, the tube presenting a slit running longitudinally through the tube; and a base comprising a flat support surface parallel to the axis of the tube, the tube being configured to allow passage of the mammal through the tube from the inlet to the outlet so that the mammal engages the jacket when exiting from the tube.
