Liquid Ejecting Device Absolute Humidity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face confusion when adjusting the installation environment for a liquid ejecting device due to the interdependence of temperature and relative humidity, which can lead to unnecessary adjustments and misalignment with recommended conditions.
Innovation Solution
A liquid ejecting device with a control unit that displays and adjusts for both temperature and absolute humidity conditions independently, using a display unit to prompt specific adjustments for temperature and humidity, and incorporating machine learning to optimize adjustment guidance based on environmental changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the temperature of the installation environment is adjusted to satisfy the recommended temperature condition after the relative humidity is adjusted, then the temperature condition is satisfied, but the relative humidity changes and requires readjustment
Solution Approach 1:
The patent changes the humidity parameter from relative humidity to absolute humidity. Absolute humidity is independent of temperature, so adjusting temperature no longer causes humidity to change. This parameter substitution resolves the interdependence issue and allows independent adjustment of temperature and humidity conditions.
2Object-affected harmful factors
If relative humidity is used as the recommended condition, then humidity control is provided, but temperature and humidity are linked causing user confusion
Solution Approach 1:
The patent substitutes relative humidity with absolute humidity as the control parameter. Absolute humidity directly represents the water vapor content without being influenced by temperature, providing clear and independent environmental condition information that eliminates user confusion about the temperature-humidity relationship.

AI summary
A liquid ejecting device includes a housing, an ejecting unit located in the housing that ejects liquid onto a medium, and a display unit that displays a recommended condition of an installation environment where a device is installed. The display unit displays, as the recommended condition, any of (a) a recommended temperature condition indicating a recommended temperature range, (b) a recommended relative humidity condition indicating a recommended relative humidity range, (c) a recommended absolute humidity condition indicating a recommended absolute humidity range, and (d) a recommended temperature condition and a recommended absolute humidity condition.
