Control Board Positioning in Recording Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices face an issue of increased size due to unnecessary space coverage by the control board, leading to a larger housing.
Innovation Solution
The control board is strategically positioned below the carriage when it is at one end of the guide shaft, and attached to a side frame, optimizing space usage and minimizing the device's size in both the width and height directions.

Engineering Contradiction Analysis
1Volume of moving object
If the control board is disposed in a conventional position not considering carriage movement range, then the control board can be easily installed, but the housing size increases unnecessarily
Solution Approach 1:
The control board is positioned in the vertical dimension below the carriage movement path rather than occupying horizontal space. This dimensional repositioning allows the control board to be located within the carriage's vertical clearance zone, reducing the housing width without complicating the installation process
Solution Approach 2:
The control board position is determined based on the dynamic movement range of the carriage. By positioning the control board below the carriage when it is at one end of the guide shaft, the design accounts for the carriage's motion trajectory, ensuring the control board remains accessible while minimizing housing dimensions
2Volume of moving object
If the control board position is optimized to reduce housing size, then the device becomes more compact, but the control board placement becomes more complex
Solution Approach 1:
The housing space is segmented into functional zones: the carriage movement zone above the guide shaft and the control board mounting zone below it. This spatial segmentation allows independent optimization of each zone, reducing overall device size while maintaining simple control board placement through clear zone definition

AI summary
A recording device includes a recording head configured to discharge a liquid as a droplet, a carriage on which the recording head is mounted, a driving unit that causes the carriage to reciprocate along a guide shaft, and a control board on which a semiconductor element is mounted. In a state in which the carriage is positioned at one end of the guide shaft, the control board is disposed below the carriage.
