Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high manufacturing cost of preparation apparatuses for moisture-proof materials is due to the need for different viscosity sensors with varying measurement ranges to achieve accurate viscosity measurements, leading to increased costs.
Innovation Solution
A preparation apparatus that measures the viscosity of an undiluted solution based on supply time at constant pressure and adjusts the amount of a diluted solution to achieve target viscosity, eliminating the need for a viscosity sensor in the initial stage of preparation.

Engineering Contradiction Analysis
1Measurement precision
If different viscosity sensors with different measurement ranges are used to enable wide range viscosity measurement, then measurement accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The invention extracts the viscosity measurement function from the traditional viscosity sensor and implements it through a timing-based measurement method. By measuring the time required for a specified amount of liquid to flow from the first tank to the preparation tank at constant pressure, the system determines viscosity without requiring expensive sensors, thereby reducing manufacturing cost while maintaining measurement capability
Solution Approach 2:
The invention replaces the mechanical/electrical viscosity sensor system with a timing-based measurement system. Instead of using a sensor to directly measure viscosity, the system uses a timer to measure the flow time of the liquid under constant pressure, substituting a simple timing mechanism for complex sensing equipment, thus reducing cost while achieving accurate viscosity determination

AI summary
A preparation apparatus includes a first tank, a second tank, a preparation tank, and a computer having a hardware processor. The first tank contains a first liquid. The second tank contains a second liquid having a lower viscosity than the first liquid. The preparation tank stirs the first liquid supplied from the first tank and the second liquid supplied from the second tank to prepare a preparation liquid. The hardware processor measures a viscosity of the first liquid based on a supply time required to supply a specified amount of the first liquid at a constant pressure from the first tank to the preparation tank, and supplies an amount of the second liquid to the preparation tank based on the measured viscosity of the first liquid so as to cause the preparation liquid to have a target viscosity.
