Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid jet recording devices face challenges in reducing the size of their drive boards due to increased wiring complexity and width resulting from the need for high-definition nozzle arrangements.
Innovation Solution
The drive board is configured with drive devices arranged side by side along a direction, and each drive device generates signals for specific nozzle groups, with simplified wiring patterns and reduced components to minimize size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-definition nozzle arrangements are used, then printing resolution is improved, but drive board size and wiring complexity increase
Solution Approach 1:
The patent divides the drive board into multiple drive device units, each responsible for specific nozzle groups. This segmentation allows the drive board to be scaled and configured according to the number of nozzles without requiring a complete redesign, thus managing the increase in drive board size while supporting high-definition nozzle arrangements.
Solution Approach 2:
The patent arranges drive devices and nozzles in a two-dimensional matrix configuration, with drive devices positioned along a first direction and nozzles along a second direction. This dimensional organization optimizes wiring paths and reduces the overall drive board area required for high-definition configurations.
2Measurement precision
If high-definition nozzle arrangements are used, then printing resolution is improved, but wiring complexity increases
Solution Approach 1:
Each drive device is configured to drive a specific group of nozzles, creating modular units with dedicated wiring. This segmentation reduces wiring complexity by eliminating the need for complex cross-connecting wires between different drive devices and nozzle groups, while still supporting high-definition arrangements.
Solution Approach 2:
The patent organizes the wiring structure in two dimensions, with drive devices arranged along a first direction and nozzles along a second direction. This dimensional arrangement creates systematic wiring paths that are easier to manage and less complex than conventional one-dimensional arrangements, facilitating high-definition nozzle configurations.
