Swinging Ink Stirring Member with Buffer for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ink stirring mechanisms in printing apparatuses generate significant noise due to the collision of the stirring member with the ink storage chamber walls, which affects the uniformity of ink concentration and printing quality.
Innovation Solution
A liquid storage container with a stirring member that swings within the ink storage chamber, featuring a buffer member between the stirring member and its support structure to absorb impacts and reduce noise, and optionally additional buffer members on the stirring surface or inner chamber walls to further suppress noise during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stirring member is provided in the ink storage chamber to stir the ink, then the ink concentration uniformity is improved, but the noise generated during operation increases
Solution Approach 1:
A buffer member is introduced as an intermediary element between the stirring member and the ink storage chamber wall. This buffer member absorbs the impact when the stirring member contacts the chamber wall, thereby reducing noise while allowing the stirring member to continue its noise-reducing stirring function
Solution Approach 2:
The buffer member is pre-installed at the position where the stirring member may contact the chamber wall. This beforehand cushioning arrangement ensures that when contact occurs during stirring operation, the impact is already mitigated by the buffer member, reducing noise generation
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 solution effectively reduces noise generated during ink stirring, ensuring uniform ink concentration and improved printing performance by minimizing collision noise between the stirring member and the chamber walls.
Implementation Method 1
a first buffer member is provided between the supporting structure and the stirring member... collision noise, which is generated between the support structure and the stirring member by a vibration of the stirring member with respect to the support structure generated due to the fact that the stirring member collides with the wall surface of the liquid storage chamber, can be decreased
