Solution Overview

Problem

Oral tablets for delivering active ingredients face delays in efficacy, swallowing difficulties, and adverse sensorial properties such as off-notes, which compromise convenience and effectiveness.

Innovation Solution

A flowpack containing a population of particles comprising at least two types of sugar alcohol particles, including granulated and non-directly compressible sugar alcohol particles, designed to rapidly liquify in the oral cavity, enhancing saliva generation and sensorial properties like mouthfeel, flavor, and cooling sensation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If oral tablets are used for delivery of active ingredients, then uniformity of content and appropriate route of administration are secured, but time delay from administration to full efficacy occurs and convenience is compromised

Engineering Contradiction:

Improveuniformity of contentVSAvoidtime delay to full efficacy

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent changes the physical state and formulation parameters of the active ingredient delivery system by using a powder composition with specific particle size distributions (D10, D50, D90 values) and flowability characteristics (Hausner ratio, angle of repose) to achieve rapid dissolution and absorption while maintaining uniform content distribution

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs a porous or highly divided solid matrix in the powder composition that increases surface area and facilitates rapid release of active ingredients upon contact with oral fluids, reducing the time delay to full efficacy while maintaining reliable dosing

Inventive Principle:

Principle #31Porous materials

2Reliability

If oral tablets are formulated for gastrointestinal delivery, then appropriate route of administration is achieved, but swallowing difficulties and poor convenience result

Engineering Contradiction:

Improveappropriate route of administrationVSAvoidconvenience of administration

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the traditional tablet formulation into a free-flowing powder composition that can be easily administered via spoon or dispenser, eliminating swallowing difficulties while ensuring the powder reaches the gastrointestinal tract for appropriate absorption

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent utilizes the hydraulic properties of oral fluids (saliva, gastric juices) to facilitate rapid wetting, dissolution, and dispersion of the powder composition, enabling convenient administration without requiring the patient to swallow solid tablets

Inventive Principle:

Principle #29Pneumatics and hydraulics

3Productivity

If active ingredients are released rapidly from oral tablets, then effectiveness is improved, but off-notes and adverse sensorial properties increase

Engineering Contradiction:

Improverelease rate of active ingredientVSAvoidoff-notes and adverse sensorial properties

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality control by using a bimodal or multimodal particle size distribution where finer particles provide rapid release for effectiveness while coarser particles provide bulk and mask off-notes, creating different functional zones within the same powder composition

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent creates a composite powder material consisting of active ingredient particles combined with excipients or carriers in specific ratios, where the composite structure enables both rapid release of active成分 and masking of adverse sensorial properties through the combined characteristics of the components

Inventive Principle:

Principle #40Composite materials
