Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stirring devices for liquids have complex configurations that hinder high stirring efficiency, necessitating a simpler design for effective liquid mixing and deaeration in recording apparatuses.
Innovation Solution
A rod-shaped stirring element with magnetic forces at both ends and plate-shaped blades extending from each end, allowing for efficient ink mixing and deaeration in the sub tank by rotating within the ink circulation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a supporting body with attached stirring blades is used, then stirring function is provided, but device complexity increases
Solution Approach 1:
The patent combines the stirring blade and the rod-shaped body into a single integrated structure. The blade is formed as one piece with the rod-shaped body, eliminating the need for separate supporting bodies and attached blades. This merging reduces the number of components and simplifies the overall configuration while maintaining the stirring function.
Solution Approach 2:
The patent removes the complex supporting body structure from the design. Instead of having a separate supporting body with attached blades, the invention extracts only the essential functional elements (the rod-shaped body with integrated blade) needed for stirring, thereby reducing device complexity.
2Productivity
If magnetic forces are concentrated at both ends of the rod-shaped body, then magnetic stirring efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the magnetic force distribution into two distinct concentrated regions at opposite ends of the rod-shaped body. This segmentation of magnetic poles (N pole and S pole at opposite ends) creates a bipolar magnetic field configuration that enhances stirring efficiency by providing stronger magnetic forces at the ends where the blade contacts the liquid, while the manufacturing process follows conventional magnet assembly techniques.

Function Achieved in This Case
The solution enhances stirring efficiency and deaeration performance, reducing operation time and maintaining ink quality by effectively mixing high-concentration ink from the bottom with surface ink and removing dissolved oxygen, thus preventing bubble blockages in the recording head.
Implementation Method 1
a rod-shaped body configured to have a magnetic force at a first end portion and to have a magnet force at a second end portion opposite to the first end portion in a longitudinal direction
