Conveyance Unit Size Reduction for Printing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses with larger conveyance units for handling larger recording media incur increased transportation costs, and previous solutions requiring division and reassembly of conveyance units are time-consuming and labor-intensive.
Innovation Solution
A conveyance device and printing apparatus that can easily reduce and restore the conveyance unit in size, allowing for modular transportation and installation without the need for on-site assembly or disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conveyance unit is made larger to handle larger recording media, then the handling capability is improved, but the transportation cost increases
Solution Approach 1:
The conveyance unit is divided into multiple separable components: a fixed section and a movable section that can be detached. This segmentation allows the conveyance unit to be configured in different sizes depending on the recording medium being handled, while also enabling partial disassembly for transportation, thus reducing transportation costs without compromising handling capability when fully assembled
Solution Approach 2:
The conveyance unit incorporates a movable section that can be extended or retracted based on the size of the recording medium. This dynamic configuration allows the system to adapt its size and capacity to match the specific handling requirements, avoiding the need to always transport a fully extended large-scale conveyance unit
2Quantity of substance
If the conveyance unit is divided into blocks for separate transportation, then the transportation cost is reduced, but the time and effort required for assembly and disassembly increases
Solution Approach 1:
The conveyance unit is segmented into a fixed section and a movable section that can be easily separated. This segmentation is designed to allow quick connection and disconnection operations, reducing the time and effort required for assembly and disassembly while still enabling separate transportation of the sections to reduce transportation costs
Solution Approach 2:
The movable section is designed to be stored within or alongside the fixed section when not in use. This nesting arrangement minimizes the space required for storage and facilitates easy assembly by simply extracting the movable section from its stored position, thereby reducing both assembly time and storage requirements
3Adaptability or versatility
If the conveyance unit is made larger to handle larger recording media, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
By dividing the conveyance unit into a fixed section and a movable section, the complexity of managing a single large conveyance unit is reduced. Each section can be independently controlled and maintained, simplifying the overall system complexity while retaining the ability to handle various sizes of recording media through appropriate configuration
