Printer Guide Device Adjuster for Carriage Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices for printers fail to maintain a consistent gap between the liquid discharge head and the printing medium, leading to degradation in image quality due to tilting and non-uniformity of the carriage, which affects the printing process.
Innovation Solution
A guide device with an adjuster mechanism that includes adjustment plates and screws to adjust the distance and alignment of the attachment surface on a stay, allowing for precise correction of the carriage's tilt and straightness, ensuring a consistent gap and improved image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the guide device uses a fixed attachment structure, then the device complexity is low, but the manufacturing precision of the gap between the liquid discharge head and printing medium deteriorates
Solution Approach 1:
The patent applies the dynamics principle by introducing an adjuster mechanism that allows the attachment surface to be dynamically repositioned. The adjuster includes an adjustment plate and push member that enable changing the distance between the attachment portion and facing portion, allowing the guide device to adapt to different carriage positions and maintain consistent gap measurements during manufacturing and assembly.
2Manufacturing precision
If the attachment surface is fixed on the stay, then the ease of manufacture is high, but the manufacturing precision of carriage alignment deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the stay into distinct functional portions: an attachment portion for securing the guide, a facing portion for reference, and an adjuster mechanism in between. This segmentation allows independent adjustment of the attachment surface position without affecting the overall stay structure, enabling precise carriage alignment while maintaining manufacturing simplicity through modular assembly.
3Manufacturing precision
If the guide device lacks an adjustment mechanism, then the device complexity is low, but the manufacturing precision of the carriage gap deteriorates
Solution Approach 1:
The patent applies the intermediary principle by introducing an adjuster mechanism as a mediator between the fixed stay structure and the movable carriage. The adjuster includes an adjustment plate that can be pushed by a push member to change the attachment surface position, serving as an intermediary element that translates simple mechanical input into precise gap adjustment, thereby ensuring uniform carriage gap without requiring complex active control systems.

AI summary
A guide device includes a guide configured to movably hold and guide a moving-object, and a stay to which the guide is attached. The stay includes an attachment portion including an attachment surface to which the guide is attached, a facing portion facing the attachment portion, and an adjuster configured to change a distance between the attachment portion and the facing portion to partially displace the attachment surface. The adjuster includes an adjustment plate arranged between the attachment portion and the facing portion, and a push member configured to push the adjustment plate to move the attachment portion of the stay.
