Solution Overview

Problem

Oral dosage forms often pose swallowing difficulties for various populations, including children and the elderly, and can be unpalatable, leading to non-compliance due to their solid or bitter taste, which existing alternatives have not adequately addressed.

Innovation Solution

A plurality of particles with specific physical properties, such as low flow resistance, high tensile strength, and controlled friability, are spatially arranged in a drinking device to release pharmaceutically active agents as fluid flows through, ensuring easy administration and effective delivery of medications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If solid dosage forms (tablets, capsules) are used for oral administration, then the pharmaceutical can be delivered effectively, but patients with swallowing difficulties cannot ingest them

Engineering Contradiction:
Improveease of ingestionVSAvoiddrug delivery effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The pharmaceutical is divided into multiple small particles (e.g., sand-like particles) that can be easily suspended in liquid and ingested, eliminating the swallowing difficulty associated with solid tablets and capsules while maintaining effective drug delivery through controlled dissolution in the gastrointestinal tract

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If liquid formulations (syrups, elixirs) are used to improve swallowability, then ease of ingestion is improved, but the formulations become complex and may not provide adequate drug delivery control

Engineering Contradiction:
Improveease of ingestionVSAvoidformulation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A simple liquid carrier (water, juice, or other acceptable liquids) is used as an intermediary to suspend the pharmaceutical particles, providing ease of ingestion without requiring complex syrup or elixir formulations. The particles themselves serve as the drug delivery mechanism, eliminating the need for complex liquid formulation chemistry

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If particles are made small enough to be easily ingested, then ease of ingestion is improved, but the particles may have insufficient mechanical strength and may fragment

Engineering Contradiction:
Improveease of ingestionVSAvoidparticle mechanical strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The particle properties are optimized by controlling parameters such as size (e.g., 1-500 micrometers), density, surface characteristics, and mechanical strength to achieve a balance where particles are small enough for easy ingestion but sufficiently strong to maintain integrity during handling and dissolution. The particles are designed to dissolve at a controlled rate in the gastrointestinal environment

Inventive Principle:
Principle #35Parameter changes
