Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple deposition heads are used to handle multiple products with different geometries and materials, then manufacturing versatility is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements variable speed control for each carrier independently, allowing the deposition head to maintain optimal deposition speed while carriers move at different speeds to accommodate different product geometries and materials. This dynamic speed adjustment enables a single deposition head to handle multiple product types without increasing device complexity
Solution Approach 2:
The single deposition head is designed with multi-functionality to handle different materials and geometries by adjusting deposition parameters and carrier speeds. The system achieves versatility through parameter optimization rather than through multiple specialized deposition heads, reducing device complexity while maintaining adaptability
2Productivity
If fixed platform speeds are used in layerwise manufacturing, then system simplicity is maintained, but productivity and efficiency deteriorate
Solution Approach 1:
The system implements variable speed control where each carrier can move at independently optimized speeds based on the specific product being manufactured. This dynamic speed adjustment improves productivity by optimizing deposition rates for different geometries and materials without requiring multiple deposition heads, thus not significantly increasing system complexity
Solution Approach 2:
The patent changes the speed parameter of carriers dynamically to optimize production efficiency. By adjusting carrier speeds rather than deposition head speeds, the system achieves higher productivity while maintaining relatively simple system architecture
3Adaptability or versatility
If multiple deposition heads are deployed to handle different materials and geometries simultaneously, then manufacturing flexibility is improved, but cost and device complexity increase
Solution Approach 1:
The single deposition head is designed to handle multiple materials and geometries by adjusting deposition parameters and carrier speeds. This universal approach reduces manufacturing cost compared to deploying multiple specialized deposition heads, while maintaining the flexibility to produce diverse products
Solution Approach 2:
Dynamic speed adjustment of carriers allows the single deposition head to adapt to different product requirements, achieving manufacturing flexibility without the cost of multiple deposition heads. The system optimizes deposition processes for different geometries and materials through parameter control rather than hardware multiplication
4Productivity
If carriers move at variable speeds with independent trajectory control, then production efficiency and flexibility are improved, but control system complexity increases
Solution Approach 1:
The control system optimizes carrier speeds by adjusting velocity parameters dynamically. This parameter-based control approach improves production efficiency while keeping the control system relatively simple compared to complex multi-head systems. The control focuses on speed variation rather than complex trajectory planning

AI summary
A production line for making tangible products by layerwise manufacturing. The production line includes: first and second movable carriers, each carrier comprising a transporter for transporting the carrier, and a building platform for supporting a tangible product, one or more deposition heads for depositing construction material in a deposition direction onto the building platforms, and a conveyor for conveying the first and second building platform towards the deposition head and away from the deposition head repeatedly. The first and the second transporter are movable at variable speeds relative to each other along a trajectory of the conveyor. Optionally, the height of the building platforms can be adjusted.
