Solution Overview

Problem

Existing piglet slip devices integrated into bay side walls face challenges such as high mechanical loads leading to instability, complex installation processes, and increased effort in group subsidiary systems where multiple bays require separate devices.

Innovation Solution

A one-piece framework designed as a welding group provides a stable and compact piglet slip device. The framework includes a door element that can be positioned to open or close a passage for piglets, enhancing stability and simplifying installation by reducing the number of parts and facilitating assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If piglet hatching devices are integrated into pen side walls, then piglets can access common group living area, but side walls are exposed to high mechanical stress affecting stability

Engineering Contradiction:
Improveaccess to common group living areaVSAvoidside wall stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The piglet hatching device is segmented from the pen side wall structure. Instead of integrating the hatch directly into the side wall, the patent uses a separate frame structure that can be attached to or positioned near the side wall, allowing the side wall to remain structurally independent and stable while still providing piglet access functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A frame structure acts as an intermediary between the piglet hatching device and the pen side wall. This frame serves as a mediator that bears the mechanical loads and stresses, protecting the side wall from direct stress exposure while enabling the hatching function to be performed.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If separate piglet hatching devices are installed in each farrowing pen, then each pen has independent piglet access, but installation costs increase significantly

Engineering Contradiction:
Improveindependent piglet access per penVSAvoidinstallation costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The frame structure with piglet hatching device is designed as a universal, multi-functional unit that can be used across multiple farrowing pens. The same basic design and components can be replicated and installed in different locations, reducing overall installation costs through standardization and economies of scale.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple pen-side-specific functions are merged into a single frame structure that can serve one or more pens. The frame integrates the hatching mechanism, structural support, and attachment features into one unified assembly, reducing the total number of separate components and installation steps required.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If multiple parts are used in piglet hatching device, then device functionality is achieved, but assembly complexity increases

Engineering Contradiction:
Improvedevice functionalityVSAvoidnumber of parts
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple functional parts into an integrated frame structure. The frame combines structural support elements, hatching mechanism components, and attachment features into a single welded assembly, reducing the total number of separate parts while maintaining all necessary functionalities for piglet access and device operation.

Inventive Principle:
Principle #5Merging (Combining)
