Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods for additively building objects with 3D printers are used, then the manufacturing process is simple, but interference between the build head and the object or placement apparatus is not detected
Solution Approach 1:
The system performs preliminary detection of interference between the build head and the object or placement apparatus before the actual additive manufacturing process begins. By generating model data representing the three-dimensional shape of the object and comparing it with the build head trajectory, the system identifies potential interference in advance, allowing for preventive adjustments without affecting the manufacturing timeline.
Solution Approach 2:
The system creates a digital copy (model data) of the object to be manufactured and uses this virtual representation to simulate and detect potential interference with the build head. This copying approach allows interference detection without requiring physical prototypes or test runs, maintaining simplicity while improving reliability.
2Reliability
If interference detection is implemented, then manufacturing reliability is improved, but processing time increases due to regeneration of model data and display data
Solution Approach 1:
The system performs interference detection and generates model data and display data before the actual manufacturing process begins. By completing these computational tasks in advance, the system ensures that no time is lost during production, as all necessary data preparation and interference checks are already completed.
Solution Approach 2:
The system transitions the interference detection process to a different dimension by working with digital model data in a virtual environment rather than physical space. This allows parallel processing of multiple detection scenarios without affecting the physical manufacturing timeline, effectively eliminating time loss.
3Manufacturing precision
If detailed interference information is generated and displayed, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The system uses detailed digital model data as a virtual copy to represent the precise three-dimensional shape of the object, enabling accurate interference prediction without requiring complex physical measurement systems. The display system then presents this detailed information in a simplified visual format.
Solution Approach 2:
The system introduces a display apparatus as an intermediary between the complex interference detection algorithms and the user. This mediator translates detailed technical data about build head trajectories and object geometry into visually intuitive representations, maintaining manufacturing precision while simplifying the user interface.
