Pivot Head Carriage Inkjet Printer Contact Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink jet printers face issues with maintaining good contact between data storage units and contact terminals, and smooth ink supply due to the adjustment of the recording head's angle, leading to potential data reading and writing failures and ink supply disruptions.
Innovation Solution
A recording apparatus with a carriage that includes a mechanism to adjust the recording head's position using a pivot mechanism, ensuring that the data storage unit remains in contact with the contact terminal and the ink supply portion remains connected, even when the head unit is turned, utilizing a positioner portion and a receiving portion with elasticity to prevent damage and maintain ink flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the recording head is turned to adjust the angle with respect to the sheet transport direction, then the adaptability of the recording apparatus is improved, but the contact between the data storage unit and the contact terminal is disrupted
Solution Approach 1:
The carriage is divided into two independent units: the moving unit that holds the data storage unit and contact terminal, and the recording unit that contains the recording head. This segmentation allows the recording head to be turned for angle adjustment while the moving unit remains stationary, maintaining reliable contact between the data storage unit and contact terminal throughout the adjustment process.
2Adaptability or versatility
If the recording head is turned to adjust the angle with respect to the sheet transport direction, then the adaptability of the recording apparatus is improved, but the ink supply from the ink cartridge to the recording head is disrupted
Solution Approach 1:
The carriage is divided into two independent units: the moving unit that holds the ink cartridge and maintains its position, and the recording unit that contains the recording head. This segmentation allows the recording head to be turned for angle adjustment while the ink cartridge remains stationary, ensuring continuous and stable ink supply throughout the adjustment process.
3Reliability
If the carriage is divided into two units to maintain contact and ink supply during adjustment, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The carriage is segmented into a moving unit and a recording unit, each with independent functions. The moving unit handles ink cartridge positioning and data storage unit contact, while the recording unit handles recording head adjustment. This functional segmentation maintains reliability during angle adjustment while keeping the overall structure relatively simple through clear division of responsibilities.

AI summary
A recording apparatus has a carriage in which a head unit including a recording head is disposed. By turning the head unit within the carriage about a pivot that extends in a direction intersecting a head surface, the angle of the recording head is adjusted while maintaining good contact between a data storage unit included in an ink cartridge and a contact terminal included in the carriage.
