Solution Overview
Problem
Print medium finishing apparatuses face challenges in aligning print media without misalignment during discharge, with simple structures prone to misalignment and complex structures required for precise positioning.
Innovation Solution
A print medium finishing apparatus featuring a rotatable driving gear, motion converting gear, and a grip member that moves linearly and curvilinearly, using a separating-preventing protrusion and groove mechanism to maintain alignment and prevent misalignment during discharge to a stacker tray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple pushing structure is used to discharge print media, then the device complexity is reduced, but the manufacturing precision of print media alignment deteriorates
Solution Approach 1:
A grip member is introduced as an intermediary component between the pushing mechanism and the print media. The grip member holds the print media during discharge, ensuring precise alignment while being discharged to the stacker tray, thus resolving the contradiction between simple structure and alignment precision
Solution Approach 2:
The traditional direct pushing mechanism is replaced with a gear-based mechanical system. The driving gear and motion converting gear work together to control the grip member's movement, providing precise positioning while maintaining a relatively simple overall structure
2Manufacturing precision
If a complex structure with multiple components is used to control grip member position, then the manufacturing precision of print media alignment is improved, but the device complexity increases
Solution Approach 1:
Multiple functions are merged into the gear system. The driving gear not only provides motion but also controls the position of the grip member through its engagement with the motion converting gear. This integration reduces the need for separate positioning mechanisms, achieving precise alignment without excessive complexity
Solution Approach 2:
The motion converting gear serves multiple purposes: it converts the rotational motion of the driving gear into linear motion, controls the position of the grip member, and ensures precise alignment of the print media during discharge. This multi-functionality reduces overall system complexity while maintaining precision
