Scanner Unit Protrusion Depth Arrangement for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink jet complex machines require a reduction in height while maintaining resistance to vibration and impact, as existing designs with integrated scanner and recording units face challenges in minimizing height without compromising structural integrity.
Innovation Solution
The arrangement of the scanner unit's protrusion and carriage in a non-overlapping manner, with the protrusion positioned relative to the rotational movement shaft, allows for a reduced height configuration while enhancing resistance to impact and vibration by optimizing the gravity center position and movement of the scanner unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the scanner unit is provided with a protrusion and the guide rail is arranged in the protrusion, then the thickness of the overall scanner unit can be reduced and the dimension of the overall ink jet complex machine in the apparatus height direction can be reduced, but the scanner unit becomes more susceptible to vibration and impact
Solution Approach 1:
The patent transitions from a vertically stacked arrangement (protrusion directly above carriage) to a horizontally distributed arrangement along the depth direction. The protrusion, carriage, and rotational movement shaft are positioned at different depths, creating a three-dimensional layout that reduces height while maintaining structural integrity and resistance to vibration and impact.
2Length of stationary object
If the protrusion and carriage are arranged in a superimposed manner, then the apparatus height can be reduced, but the resistance to vibration and impact deteriorates
Solution Approach 1:
The patent segments the vertical stacking of components into horizontal distribution. Instead of placing the protrusion directly above the carriage in a superimposed manner, the components are separated along the depth direction, creating distinct positional zones that reduce stress concentration and improve impact resistance while maintaining compact height.
3Adaptability or versatility
If the scanner unit is moved rotationally to open and close the upper side, then multifunctionality is achieved, but the movement generates vibration and impact
Solution Approach 1:
The patent positions the protrusion, carriage, and rotational movement shaft in advance at optimized locations along the depth direction. This preliminary spatial arrangement ensures that during rotational movement, the components maintain stable relative positions, minimizing vibration and impact while enabling the scanner unit to open and close effectively.

AI summary
An ink jet printer is a multifunctional recording apparatus in which a scanner unit is coupled to a recording unit in a rotationally movable manner. The scanner unit includes a protrusion. A carriage, the protrusion, and a rotational movement shaft of the scanner unit are arranged in this order from the unit front side to the unit rear side in the unit depth direction.
