Inkjet Head Position Adjustment Mechanism for Compact Carriage Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid jet recording devices require a significant installation area for the liquid jet head, which limits their compactness and density in recording devices.
Innovation Solution
The liquid jet recording device incorporates a position adjustment mechanism with a position adjustment member and biasing member integrated into the base plate of the inkjet head, allowing for precise adjustment of the nozzle array's position relative to the carriage, thereby reducing the necessary installation area and enabling higher density packing of inkjet heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the liquid jet head is installed with a traditional nozzle array configuration, then the recording function is achieved, but the installation area becomes large
Solution Approach 1:
The patent introduces a position adjustment mechanism that allows the nozzle array to be dynamically positioned relative to the carriage. The adjustment member can be rotated to adjust the position of the nozzle array in the width direction of the recording medium, enabling precise positioning without requiring a large fixed installation area. This dynamic adjustment capability resolves the contradiction by providing positioning flexibility within a compact space.
Solution Approach 2:
The patent utilizes the width direction of the recording medium as an additional dimension for position adjustment. By allowing the nozzle array to be positioned at different locations in the width direction through the position adjustment mechanism, the system achieves precise recording positioning without increasing the installation area in the other dimensions. This dimensional approach enables compact installation while maintaining recording precision.
2Area of stationary object
If the installation area for the liquid jet head is reduced, then compactness is improved, but the positioning accuracy of the nozzle array may be compromised
Solution Approach 1:
The patent replaces complex mechanical positioning systems with a simpler rotational adjustment mechanism. Instead of requiring large mechanical structures for precise positioning, the system uses a rotationally adjustable member that can be turned to achieve precise nozzle array positioning. This substitution allows high positioning precision to be achieved within a compact installation area by using rotational motion rather than linear mechanical displacement.
Solution Approach 2:
The position adjustment member acts as an intermediary between the compact installation structure and the precise positioning requirement. This intermediate component translates simple rotational motion into precise positional adjustment of the nozzle array, enabling accurate positioning without requiring the nozzle array to be directly mounted on a complex positioning mechanism. The intermediary element facilitates both compact installation and precise positioning.
