Solution Overview
Problem
Existing liquid ejection devices face limitations in ejection amount and cleaning effectiveness, either due to excessive liquid discharge or insufficient cleaning force when converting continuous flow into droplets.
Innovation Solution
A liquid ejection device that includes a head unit and a liquid transport tube, where the liquid contains a solvent and a cleaning agent with a concentration of 1% to 10% by weight, ejected in a continuous flow and converted into droplets for improved cleaning efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a high-pressure pump is used to increase ejection pressure, then cleaning power is improved, but ejection amount becomes too large and application scenarios are limited
Solution Approach 1:
The patent changes the chemical composition parameters of the liquid by adding cleaning agents at specific concentrations (1-10% by weight) to enhance cleaning power without increasing ejection pressure or amount. This allows the liquid to clean effectively while maintaining controlled ejection quantities suitable for various application scenarios.
2Quantity of substance
If continuous flow is converted into droplets to reduce ejection amount, then ejection amount is reduced, but cleaning force becomes insufficient
Solution Approach 1:
The patent creates a composite liquid formulation combining solvent and cleaning agents in specific proportions. This composite liquid maintains droplet form for reduced ejection amount while the cleaning agent components provide sufficient cleaning force through their chemical action, resolving the contradiction between reduced quantity and maintained cleaning effectiveness.
3Force
If cleaning agent concentration is increased to improve cleaning effect, then cleaning effectiveness is improved, but cost increases and workability decreases
Solution Approach 1:
The patent optimizes the concentration parameter of cleaning agents within the range of 1-10% by weight. This parameter optimization achieves sufficient cleaning effectiveness while controlling costs and maintaining workability, avoiding the drawbacks of excessive concentration such as increased cost and reduced workability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves controlled ejection amounts and enhanced cleaning effectiveness by using a solvent with a cleaning agent concentration of 1% to 10%, preventing foaming and cost increases while maintaining workability.
Implementation Method 1
the liquid is ejected from the head unit in a continuous flow and the continuous flow is converted into droplets to collide with the object in a form of droplets
Implementation Method 2
the liquid contains a solvent and a cleaning agent having a stronger cleaning power for cleaning an attached matter attached to an object than the solvent
