Solution Overview

Problem

Current formulations of liposoluble vitamins, particularly vitamin D, lack a sprayable liquid form, which is essential for effective administration due to their liposoluble nature, and existing oily solutions are cumbersome and have poor bioavailability when used in pediatric and adolescent populations.

Innovation Solution

A sprayable oily liquid formulation comprising liposoluble vitamins like vitamin D3, utilizing a medium chain triglyceride (MCT) oil and triglycerides of caprylic and capric acids, which are compressible and stable, allowing for precise and repeatable dosing without the oily feeling, achieved through a specific weight ratio and heating process to deactivate lipases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If oily solutions of vitamin D are used in drop form, then the vitamin can be administered, but the administration is difficult and the palatability is poor

Engineering Contradiction:
Improveease of administrationVSAvoidunpleasant taste and oily feeling
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical parameters of the oily solution by adjusting viscosity through specific triglyceride selection and adding suspending agents, allowing the formulation to be delivered as an aerosol spray rather than drops, fundamentally improving ease of administration and palatability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical drop-delivery system with an aerosol spray system that uses pressurized gas to deliver the vitamin formulation as a fine mist, eliminating the need for manual dropper administration and improving patient compliance

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

2Ease of manufacture

If solid or aqueous dispersions of vitamin D are developed to reduce limitations, then the formulation is easier to handle, but the bioavailability of the vitamin is reduced

Engineering Contradiction:
Improveformulation handlingVSAvoidvitamin bioavailability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent creates a composite oily formulation combining vitamin D with specific triglycerides (medium-chain and long-chain) and suspending agents that maintain the vitamin in a dissolved state while providing sprayable physical properties, achieving both ease of manufacture and high bioavailability

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent uses triglycerides as intermediary substances that solubilize the liposoluble vitamin D and allow it to be delivered in a sprayable formulation, maintaining the vitamin's bioavailability while enabling new delivery mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a sprayable formulation is created, then the ease of administration is improved, but the compressibility of oils under pressure must be achieved

Engineering Contradiction:
Improveease of administrationVSAvoidcompressibility of oil
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent changes the physical parameters of the oily solution by adjusting viscosity through specific triglyceride selection and adding suspending agents, allowing the formulation to be compressed and sprayed effectively

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes pneumatic principles by incorporating a pressurized aerosol delivery system that forces the oily vitamin formulation through a valve and nozzle, achieving sprayable delivery despite the natural resistance of oil to compression

Inventive Principle:
Principle #29Pneumatics and hydraulics
