Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a driving mechanism is used to move the panel-carrying platform to a predetermined position, then the panel can be positioned for printing, but the structure becomes more complex and positioning accuracy decreases due to additional operating platforms and potential positional deviations
Solution Approach 1:
The patent removes the panel-carrying platform and driving mechanism from the system. Instead of moving the panel to a predetermined position using a complex driving mechanism, the panel remains stationary on the conveyor belt while the inkjet assembly moves to perform printing directly on the panel's surface, eliminating positioning errors associated with platform movement
Solution Approach 2:
The conveyor belt serves multiple functions: it conveys the panel through the processing zone and simultaneously positions the panel for printing by controlling its movement speed and position. The inkjet assembly also serves dual purposes by both moving along the conveyor belt and performing the printing function, reducing the need for separate positioning mechanisms
2Ease of operation
If a panel-carrying platform with driving mechanism is used, then the panel can be transported to processing zone, but positional deviations occur causing the panel's centerline to be non-parallel with transport direction
Solution Approach 1:
The patent replaces the mechanical driving mechanism that moves the entire panel-carrying platform with a conveyor belt system that only conveys the panel. The inkjet assembly uses a moving mechanism with sliders and guide rails to position itself, substituting the complex panel transport mechanics with simpler, more accurate positioning systems
Solution Approach 2:
The conveyor belt acts as an intermediary that smoothly transports the panel without the mechanical complexities of a driving mechanism. The belt's continuous movement provides stable panel conveyance, while the inkjet assembly's independent positioning system handles precise alignment, separating the transport and positioning functions
3Manufacturing precision
If additional operating platform is added for panel positioning, then the panel can be processed, but the device structure becomes more complex and cost increases
Solution Approach 1:
The patent merges the panel positioning function with the conveyor belt system. The conveyor belt not only transports the panel but also provides the positioning capability through controlled movement. The inkjet assembly integrates the moving mechanism directly onto the conveyor belt structure, eliminating the need for a separate operating platform
