Print System With Overlapping Upper And Lower Moving Routes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing print systems for can bodies lack a mechanism to differentiate the positional relationships between upper and lower moving routes and their respective processing units, leading to inefficient processing and increased system size due to the need for processing units on both sides.
Innovation Solution
A print system design where the upper and lower moving routes are parallel and overlap when projected vertically, with processing units positioned on both lateral sides of these routes, allowing for differential positional relationships and reduced system size by enabling processing on both sides of the routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If processing units are provided on both lateral sides of the moving routes, then processing efficiency is improved, but system size increases
Solution Approach 1:
The patent utilizes the vertical dimension by configuring the upper moving route above the lower moving route, allowing processing units to be arranged in three-dimensional space rather than only horizontally. This enables multiple processing units to operate simultaneously at different heights while maintaining a compact horizontal footprint, thereby improving processing efficiency without proportionally increasing system size.
Solution Approach 2:
The patent merges the upper and lower moving routes in the vertical projection, allowing them to overlap when viewed from above. This spatial merging enables processing units on both lateral sides to share the same horizontal space at different heights, effectively doubling processing capacity without doubling the horizontal occupation area.
2Area of stationary object
If upper and lower moving routes are configured to overlap in vertical projection, then system occupation area is reduced, but positional relationship control complexity increases
Solution Approach 1:
The patent segments the moving routes into distinct upper and lower levels, with each level having its own dedicated processing units and control mechanisms. This segmentation allows independent control of each route's positional relationships, simplifying the overall control complexity despite the three-dimensional configuration. Each level can be controlled separately rather than requiring coordinated control of a complex intertwined system.

AI summary
A print system includes: a moving body supporting a can body and moving; an upper moving route extending in a lateral direction, which is taken by the moving body when moving in one direction; a lower moving route positioned below the upper moving route, which extends in the lateral direction and is taken by the moving body when moving in a direction opposite to the one direction; and an image forming unit performing image formation onto the can body supported by the moving body. In comparison between the orientation of the moving body while the moving body is positioned on the upper moving route and the orientation of the moving body while the moving body is positioned on the lower moving route, the moving body is turned upside down.
