Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home care products, such as hard surface cleaners, often require large volumes of water, leading to increased costs due to processing, transportation, and packaging, and dissolvable tablets have lengthy dissolution times.
Innovation Solution
Effervescent compositions comprising alkali metal carbonates, acids, surfactants, and disintegrant agents, formulated to be substantially free of water, with optimized ratios and amounts to achieve rapid dissolution times of 6-12 minutes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional home care products utilize large volumes of water as the primary vehicle, then the active ingredients can be effectively contained and delivered, but the costs increase due to processing, transportation, and packaging requirements
Solution Approach 1:
The patent extracts water from the conventional liquid cleaner formulation, transitioning to a water-free effervescent tablet format. The active cleaning ingredients are embedded in a solid effervescent matrix that reacts with water during use, eliminating the need to transport and process large volumes of water while maintaining cleaning effectiveness
Solution Approach 2:
The patent changes the physical state parameter of the cleaner from liquid to solid effervescent tablet form. This parameter change allows the product to be concentrated and stable in solid form, then transform back to liquid solution through effervescent reaction with water during application, solving the transportation and storage cost issue
2Quantity of substance
If conventional dissolvable tablets are used to reduce water volume, then transportation and storage costs decrease, but the dissolution time becomes excessively long
Solution Approach 1:
The patent incorporates effervescent agents (such as sodium bicarbonate and citric acid) into the tablet formulation in advance. When the tablet contacts water, these pre-positioned agents rapidly generate carbon dioxide gas bubbles that actively disintegrate and dissolve the tablet, reducing dissolution time from potentially hours to minutes while maintaining the concentrated water-free formulation
Solution Approach 2:
The patent utilizes the phase transition from solid tablet to liquid solution through effervescent reaction. The rapid gas evolution during this phase transition creates mechanical disruption and increased surface area, dramatically accelerating the dissolution process compared to simple diffusion-based dissolution of conventional tablets
3Loss of time
If effervescent agents are added to accelerate dissolution, then the dissolution time decreases, but the formulation complexity increases
Solution Approach 1:
The patent merges the effervescent agents (sodium bicarbonate, citric acid) with the cleaning active ingredients and surfactants into a single integrated effervescent tablet formulation. This combining approach achieves rapid dissolution through effervescence while maintaining a unified, relatively simple manufacturing process that mixes all components into a homogeneous tablet matrix
