Animal Drinking Bowl Insert for Chemical Resistance

Solution Overview

Problem

Drinking troughs for poultry are prone to damage from aggressive liquids and pecking, as the plastic water-collecting bowls soften when exposed to cleaning agents, leading to holes and rendering them unusable.

Innovation Solution

A water-collecting bowl design featuring a dish part made of inexpensive thermoplastic with a robust, resistant insert positioned in areas where aggressive liquids accumulate, protecting the bowl from damage by pecking animals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the water-collecting bowl is made entirely of inexpensive thermoplastic material, then manufacturing cost is reduced, but the bowl becomes vulnerable to softening from cleaning agents and damage from pecking

Engineering Contradiction:

Improvemanufacturing costVSAvoidresistance to cleaning agents and pecking

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent applies local quality by inserting resistant material only in specific areas where cleaning agents accumulate and where pecking damage is most likely to occur, rather than making the entire bowl from expensive resistant material. This localized approach maintains low manufacturing costs while providing targeted protection against damage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses composite materials by combining inexpensive thermoplastic material for the main bowl structure with inserts made of resistant materials (such as stainless steel or chemical-resistant plastics) in critical areas. This composite construction provides both cost-effectiveness and durability where needed.

Inventive Principle:

Principle #40Composite materials

2Reliability

If resistant material is used throughout the entire water-collecting bowl, then resistance to aggressive liquids and pecking damage is improved, but manufacturing cost increases

Engineering Contradiction:

Improveresistance to cleaning agents and peckingVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies local quality by inserting resistant material only in specific areas where cleaning agents accumulate and where pecking damage is most likely to occur, rather than making the entire bowl from expensive resistant material. This localized approach maintains low manufacturing costs while providing targeted protection against damage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent applies partial action by using resistant material only to the extent necessary for protection - specifically in the lower regions where cleaning agents pool and pecking occurs - rather than applying it uniformly throughout the entire bowl structure.

Inventive Principle:

Principle #16Partial or excessive action

3Ease of manufacture

If the water-collecting bowl is made of simple thermoplastic material, then manufacturing simplicity is maintained, but the bowl softens when exposed to residual cleaning agents

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidsoftening from cleaning agents

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent uses an intermediary approach by introducing resistant material inserts as a protective layer between the cleaning agents and the thermoplastic bowl material. These inserts act as a barrier that prevents direct contact between the aggressive cleaning agents and the vulnerable plastic material.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies local quality by inserting resistant material only in specific areas where cleaning agents accumulate and where pecking damage is most likely to occur, rather than making the entire bowl from expensive resistant material. This localized approach maintains low manufacturing costs while providing targeted protection against damage.

Inventive Principle:

Principle #3Local quality

AI summary

Drinking troughs for in particular poultry feature drinking valves arranged at regular intervals along a water supply line, with each drinking valve being assigned a water-collecting bowl (14). The water-collecting bowls (14) are usually made of plastic. The water-collecting bowls (14) are cleaned with agents that contain aggressive substances, which are capable of damaging the plastic of the water-collecting bowls (14). The invention is a water-collecting bowls (14) with a respective insert (17) made of a resistant material, thus making the water-collecting bowl (14) resistant to aggressive liquids, in particular cleansing agents.
