Cow-Stall Dividing Frame With 35–45% Head Region

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing partition frame devices in cow stalls hinder species-appropriate housing by preventing free head movement and restricting the cow's ability to utilize the entire stable box area, often leading to lying in manure.

Innovation Solution

The dividing frame device is designed with a horizontal head region in the front part dimensioned to 35% to 45% of the total length, featuring an upper and lower strut arrangement with specific distances and a neck chain to allow sufficient head movement for standing, ensuring unrestricted access to the stable box area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the dividing frame is designed with traditional dimensions, then structural stability is maintained, but the cow's head movement freedom is restricted

Engineering Contradiction:

Improvehead movement freedomVSAvoidhead region length

Core Design Contradiction:

Ease of operationVSLength of stationary object

Solution Approach 1:

The patent applies parameter changes by specifically dimensioning the head region to 35%-45% of the total stable box length, and setting the upper strut-to-lower strut distance to 25-35 cm. These quantitative parameter adjustments optimize the space for head movement while maintaining structural integrity, directly resolving the contradiction between movement freedom and structural constraints.

2Ease of operation

If the stable box area is reduced, then structural simplicity is maintained, but the cow cannot utilize the entire area freely

Engineering Contradiction:

Improvemovement freedom within stable boxVSAvoidstable box area

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The patent applies local quality by creating a specifically dimensioned head region (35%-45% of total length) with optimized strut spacing (25-35 cm) that provides enhanced movement freedom where the cow needs it most, while the rest of the stable box maintains its structural simplicity. This localized optimization allows the cow to utilize the entire stable box area freely without compromising structural integrity.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the head region length is increased to 35%-45% of total length, then species-appropriate head movement is enabled, but the remaining lying area is reduced

Engineering Contradiction:

Improvespecies-appropriate housing capabilityVSAvoidremaining lying area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent resolves this contradiction through precise parameter optimization: the head region is set to 35%-45% of total length (with 40% being a preferred specific value), and the upper strut-to-lower strut distance is optimized to 25-35 cm (with 30 cm or 31 cm being specific preferred values). These parameter changes enable species-appropriate head movement while maintaining sufficient remaining lying area, achieving a balanced solution that satisfies both requirements.

AI summary

A dividing frame device (100) for lying boxes (200) for keeping cows, with a multiply curved dividing frame (110) divided into a plurality of partial areas (121, 122, 123, 124) is provided with a head area for the cow, the horizontal length of which is dimensioned to be 35% to 45% of the total horizontal length of the dividing frame in order to enable a cow to comfortably carry out a necessary head movement sufficiently far in order to generate a necessary movement moment for standing up in conjunction with a swinging movement of the head.
