Recording Head Position Adjustment via Segmented End Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face difficulties in adjusting the position of the recording head due to the positional relationship between the adjusting devices and the liquid supplying device, making precise alignment challenging.
Innovation Solution
A recording apparatus with a recording head featuring a discharge surface with multiple liquid discharge openings, a supplying member at one end to supply liquid, and a position adjusting device with a contact member at the opposite end to adjust the head's position by moving it while maintaining the other end stationary for continuous liquid supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the position adjusting device is positioned near the liquid supplying device, then the structure is compact, but it becomes difficult to adjust the recording head position
Solution Approach 1:
The recording head is divided into two functional segments: a first end portion with liquid discharge openings for recording, and a second end portion with a liquid supply connection for fluid delivery. The position adjusting device operates on the second end portion while the liquid supplying device connects to the first end portion, allowing independent optimization of adjustment accessibility and liquid supply efficiency without structural interference.
Solution Approach 2:
The patent resolves the spatial conflict by utilizing the longitudinal dimension of the recording head. The liquid supplying device is positioned at the first end portion while the position adjusting device is positioned at the second end portion, effectively using the length of the recording head to separate functions that would otherwise interfere with each other in a compact arrangement.
2Manufacturing precision
If the recording head is moved for position adjustment, then alignment precision is improved, but liquid supply consistency may be affected
Solution Approach 1:
The recording head is segmented into distinct functional zones: the first end portion containing liquid discharge openings remains stationary to maintain consistent liquid supply, while the second end portion with the liquid supply connection is moved for position adjustment. This segmentation allows independent optimization of both liquid supply stability and alignment precision.
Solution Approach 2:
Instead of moving the entire recording head for position adjustment, the patent inverts the approach by keeping the liquid supply connection end stationary and moving the liquid discharge opening end. This inversion ensures that the liquid supply pathway remains stable while achieving the necessary positional alignment.

AI summary
A recording apparatus may include a recording head including a discharge surface in which liquid discharge openings are arranged in a particular direction. The recording apparatus may include a supplying member which is positioned at a first end portion in the particular direction, and supplies the liquid to the recording head. The recording apparatus may include a liquid supplying device which is connected to the supplying member, and supplies the liquid to the recording head. The recording apparatus may include a position adjusting device including a contact member which contacts the recording head, and adjusts a position of the recording head by moving the contact member. The position adjusting device may be positioned at a second end portion opposite to the first end portion in the particular direction.
