Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated printing apparatus body is provided for each specific application, then the printing quality and functionality for that application is optimized, but the inventory stock increases and flexibility for various productions is reduced
Solution Approach 1:
The printing apparatus is divided into multiple independent transportation units (first transportation unit, second transportation unit, third transportation unit) that can be selectively connected. Each unit has specific functions (upward slope, downward slope, inclination change) and can be combined in different configurations to create dedicated apparatus bodies for different applications, thereby optimizing printing quality while reducing overall inventory needs
Solution Approach 2:
The transportation units are designed with universal interfaces and standardized connection methods that allow them to be used across different apparatus configurations. The same units can serve multiple purposes depending on how they are connected (e.g., the third transportation unit with inclination changing device can be used in various positions), enabling one set of components to support multiple production types
2Adaptability or versatility
If a dedicated printing apparatus body is provided for each specific application, then the printing functionality is optimized, but the number of apparatus types in stock increases
Solution Approach 1:
The apparatus is segmented into reusable transportation units that can be selectively assembled. Instead of manufacturing completely different apparatus bodies for each application, the same units are combined in different configurations, reducing the variety of components that need to be inventoried while maintaining full functionality
Solution Approach 2:
The system allows dynamic reconfiguration of transportation units based on specific printing requirements. The units can be connected or disconnected, and the inclination changing device can adjust angles, enabling the same physical components to adapt to different applications without requiring permanent dedicated apparatus bodies
3Reliability
If the transport path has steep slopes to maintain tension in the print medium, then the printing stability is improved, but the complexity of the transportation units increases
Solution Approach 1:
The transport path is divided into multiple segments with moderate slopes rather than one steep slope. Each transportation unit handles a specific segment, and the cumulative effect of these segments achieves the necessary tension maintenance while keeping individual unit complexity low
Solution Approach 2:
The inclination changing device provides dynamic adjustment of the transport path slope at connection points. This allows the system to adapt the angle to maintain optimal tension in the print medium while using simple geometric transitions rather than complex mechanical structures

AI summary
An inkjet printing apparatus is selectively composed of a plurality of transportation units, i.e., an inlet unit, a first intermediate unit, a second intermediate unit, and an outlet unit, having a transport path with slopes in side view of a transportation direction from a paper feeder to a take-up roller. When the transportation units are connected, a connecting part of the transportation unit is an inclination change point VP of the transport path. This achieves maintained tension to the print medium. As above, the inkjet printing apparatus may be selectively composed of a plurality of transportation units. Accordingly, the inkjet printing apparatus is constructible by combination of the units for various type productions, leading to a suppressed stock.
