Medium Support Positioning Mechanism for Compact Print Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses have separate inclination and position adjustment units, leading to increased size and a need for a more compact design.
Innovation Solution
A medium support unit with a combined position adjustment mechanism that adjusts the support surface's inclination and position in intersecting directions using multiple mechanisms that can move independently or in conjunction, integrating these functions into a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate inclination adjustment unit and position adjustment unit are provided, then precise control over medium positioning and inclination is achieved, but the size of the printing apparatus increases
Solution Approach 1:
The patent combines the inclination adjustment unit and position adjustment unit into a single integrated position adjustment mechanism. This mechanism includes multiple adjustment mechanisms (first, second, third, and fourth position adjustment mechanisms) that can independently adjust the position of the support surface in different directions. By integrating these functions, the patent achieves precise control over both the inclination and position of the medium while reducing the overall apparatus size compared to having separate units.
Solution Approach 2:
The integrated position adjustment mechanism serves multiple functions: it can adjust the inclination of the support surface by operating some adjustment mechanisms independently, and it can adjust the position of the support surface by operating all adjustment mechanisms in conjunction. This multi-functional design allows a single unit to replace what would traditionally require separate inclination and position adjustment units, thereby reducing apparatus size while maintaining precise control capabilities.
2Area of stationary object
If multiple adjustment mechanisms are integrated into a single position adjustment unit, then the apparatus size is reduced, but the complexity of the adjustment system increases
Solution Approach 1:
The position adjustment unit is divided into multiple independent adjustment mechanisms (first, second, third, and fourth position adjustment mechanisms), each responsible for adjusting the position of the support surface in specific directions. This segmentation allows each mechanism to be relatively simple in structure while collectively providing comprehensive positioning and inclination adjustment capabilities. The modular design reduces overall complexity compared to a single complex mechanism, as each segment can be independently controlled and maintained.

AI summary
A printing apparatus includes a medium support unit having a support surface that supports a medium. A position adjustment unit includes a plurality of position adjustment mechanisms that adjust a position of a support surface in an intersecting direction. The position adjustment unit can change an inclination of the support surface by some of the plurality of position adjustment mechanisms moving independently, and can change the position of the support surface in the intersecting direction by all of the plurality of position adjustment mechanisms moving in conjunction with each other.
