Compacted Fabric Tablet for Disintegration Without Aid Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid products intended to disintegrate in an aqueous medium face challenges with cohesion, stability, and the need for disintegration aid agents, which can be harmful and complicate manufacturing, while also struggling to incorporate liquid active agents effectively.
Innovation Solution
A tablet comprising two solid phases, one with a compacted powder mixture and the other with a compacted textile that swells in water to aid disintegration, eliminating the need for disintegration aid agents and allowing for the inclusion of liquid active agents, while maintaining cohesion and hardness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If disintegration aid agents are incorporated into the starting mixture to help solid products disintegrate, then disintegration kinetics are improved, but the product generates harmful factors and causes filter clogging problems
Solution Approach 1:
The patent removes disintegration aid agents from the product composition entirely. Instead, it relies on the natural swelling and disintegration properties of the compacted fabric matrix itself when exposed to aqueous medium, thereby eliminating harmful discharges and filter clogging issues while maintaining effective disintegration kinetics.
Solution Approach 2:
The compacted fabric matrix serves its dual function as both the structural carrier and the disintegration mechanism. The fabric's inherent ability to swell and separate in water provides the disintegration action without requiring additional chemical agents, making the system self-sufficient and environmentally friendly.
2Strength
If strong pressure is applied to pelletize the starting mixture to obtain a cohesive solid product, then cohesion and hardness are improved, but the product may not disintegrate effectively in aqueous medium
Solution Approach 1:
The patent applies different compaction pressures to different regions of the product. The compacted fabric matrix is compressed to provide structural integrity and hardness, while the active agent-containing powder layers are compressed to a程度 that allows water penetration and subsequent disintegration. This localized quality differentiation resolves the contradiction between maintaining strength and enabling disintegration.
Solution Approach 2:
The patent creates a composite structure combining compacted fabric matrix with powder mixtures containing active agents. The fabric provides the mechanical strength and cohesive framework, while the powder layers provide the disintegratable active components. This composite approach allows both high strength and effective disintegration to coexist.
3Adaptability or versatility
If liquid active agents are incorporated into solid products, then functional versatility is improved, but the manufacturing process becomes more complex and cohesion is compromised
Solution Approach 1:
The patent incorporates liquid active agents into the powder mixture before the pelletizing process. The liquid agents are mixed with the powder constituents in advance, allowing them to be uniformly distributed and trapped within the compacted matrix structure. This preliminary incorporation simplifies manufacturing by eliminating separate impregnation steps and ensures cohesive integration of liquid agents into the solid tablet.
