Mobile Animal Stall with Curved Lattice Roof and Skid Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile animal stables for poultry and similar animals are complex in design and fail to efficiently manage snow loads, while also not effectively preventing animals from coming into contact with manure and ground, and do not allow for easy relocation on uneven pastures.
Innovation Solution
A mobile stable with a base frame and walls, featuring a round arched roof with curved lattice girders for column-free space and snow load capacity, skids for even load distribution, and insulating sandwich panels for warmth, along with a grate system to keep animals off manure and allow scratching, and an optional aviary connected to the base frame for movement and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile stable uses wheels for movement, then it can be relocated easily, but it creates excessive ground pressure and damages the pasture
Solution Approach 1:
The patent replaces wheels with runners that have a curved, rounded bottom surface. This curvature distributes the load over a larger contact area with the ground, reducing ground pressure and preventing pasture damage while maintaining the ability to move the stable structure.
2Strength
If the stable structure is made robust to withstand snow loads, then it can handle heavy snow, but it becomes difficult to move
Solution Approach 1:
The stable structure is divided into modular components including the base frame, walls, and roof that can be assembled and disassembled. This segmentation allows the structure to be robust when assembled for snow load resistance, yet easily disassembled and relocated when needed.
Solution Approach 2:
The structure transitions from a static, fixed state during operation to a dynamic, movable state during relocation. The runners enable the heavy snow-load-capable structure to be moved by providing low-friction contact with the ground, and the modular design allows for easy assembly and disassembly.
3Object-affected harmful factors
If the floor is designed to prevent animal contact with ground, then hygiene is improved, but the construction becomes complex
Solution Approach 1:
The patent extracts the flooring function from the main stable structure by using a separate, removable floor panel system. This allows the floor to be easily cleaned, replaced, or adjusted without affecting the overall stable structure, simplifying the construction while maintaining hygiene standards.
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 mobile stable provides a simple, robust, and animal-friendly solution that allows easy relocation, manages snow loads, keeps animals clean, and maintains warmth, while allowing species-appropriate scratching and movement without excessive strain on the grazing area.
Implementation Method 1
The roof of the mobile stable is designed as a round arched roof with curved lattice girders. The trusses are designed as parallel arches. This achieves a special load-bearing capacity and rigidity of the roof.
Implementation Method 2
The walls of the mobile stable are advantageously made of insulating sandwich panels. Since the interior is heated by the animals' own heat, it can also be used in cold weather.
Implementation Method 3
For this purpose, there are eyelets on the outside of the runners, on which a tractor can pull the mobile stable and thus move it using a rope or chain. With runners, the load of the mobile stable is applied more evenly than with wheels on the pasture.

AI summary
The small animal hutch (1) is moved in pasture area with a base frame (3) that is provided in a grilled area with a penetratable grill (5) and is held free from the grill in a fatling area. The skids (2) are mounted under base frame, on which the hutch is moved to next pasture area. The outer loops are present on the skids, and the hutch is pulled by a tractor through a rope or chain. The grill is arranged so high in the base frame over the grazing area that prevents the animals from moving underneath. The solar modules (18) are mounted on the roof (6) to generate electricity for the hutch.
