Solution Overview

Problem

Existing methods for administering medications to farm animals, such as mixing powders with feed or using syringes, often result in incomplete medication due to the animals' refusal to consume unfamiliar substances or the formation of sediments.

Innovation Solution

A redesigned syringe with a piston and cylinder, featuring an opening at the end opposite the piston, allows for the direct introduction of powder or tablet-form medications into the animal's mouth, ensuring targeted delivery and complete absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If medications are mixed into feed or sprinkled onto feed, then animals can consume the medication, but animals refuse to eat unfamiliar substances resulting in incomplete medication

Engineering Contradiction:
Improvemedication absorptionVSAvoidanimal consumption
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The invention extracts the medication from the feed mixing process and delivers it directly to the animal's mouth using a syringe device. This separates the medication delivery function from feed consumption, ensuring the animal receives the full dosage without refusing to eat the medicated feed.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The syringe acts as an intermediary device between the medication and the animal. It provides a controlled delivery mechanism that presents the medication in a familiar syringe format rather than as unfamiliar medicated feed, bridging the gap between medication administration and animal acceptance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If powdered medication is used, then it can be mixed into feed, but poor dissolution leads to sediment formation and incomplete medication

Engineering Contradiction:
Improvemedication absorptionVSAvoidmedication homogeneity
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The invention replaces the chemical dissolution process with a mechanical delivery system. Instead of relying on the medication to dissolve in the animal's digestive system (which causes sedimentation), the syringe delivers the powdered medication directly in a controlled manner, ensuring complete utilization without requiring dissolution.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If traditional syringes are used for injection, then medication can be administered, but it requires veterinary assistance and is complex

Engineering Contradiction:
Improvemedication deliveryVSAvoidadministration procedure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The invention inverts the traditional syringe design by opening the barrel instead of the needle end. This allows the syringe to be filled with powdered medication and delivered orally without requiring needle insertion or veterinary skill, transforming a complex injection procedure into a simple oral administration task.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The syringe device is designed as a disposable unit that can be easily filled and used once. This eliminates the need for cleaning, sterilization, and complex maintenance associated with reusable syringes, making the system simple enough for non-veterinarians to use while ensuring hygiene.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Quantity of substance

If paste form medication is used, then it can be administered, but it sticks to the palate resulting in incomplete medication

Engineering Contradiction:
Improvemedication deliveryVSAvoidpalate adhesion
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The invention changes the physical state parameter of the medication delivery system. By delivering powdered medication through a syringe rather than using paste form, the medication does not adhere to the palate. The powdered form flows freely through the animal's mouth without sticking, eliminating the adhesion problem inherent in paste formulations.

Inventive Principle:
Principle #35Parameter changes

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 device enables a simple and effective method for administering medications directly into the mouth of farm animals, ensuring almost complete absorption and overcoming issues of refusal or incomplete medication.

Implementation Method 1

The piston, which is inserted into the cylinder and guided further along the cylinder, can be guided out of the free end of the cylinder with its end, which is usually equipped with a sliding surface. This creates a catapult effect when introducing pharmaceutical powders, as the piston can be stopped at an inward-facing ridge in the cylinder opening and only emerges from the interior of the cylinder with acceleration when further pressure is applied.
