Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If external light projection is used to manufacture 3D objects with photosensitive resin, then the manufacturing process can be implemented, but the light beam precision is insufficient and cannot accurately control the light beam direction
Solution Approach 1:
The system divides the light beam control function into multiple segments by deploying multiple swarm robots throughout the resin tank. Each robot is responsible for a specific region and controls light beam direction locally, thereby achieving high-precision overall control without requiring a single complex external projection system.
Solution Approach 2:
The swarm robots act as intermediary elements between the light source and the photosensitive resin. Instead of directly projecting light from outside, the system uses robots as intermediate controllers that dynamically adjust and modulate light beam direction, enabling precise control while maintaining system modularity.
2Reliability
If light beam direction is not precisely controlled, then the manufacturing process is simpler, but the light beam may exceed target points causing quality issues
Solution Approach 1:
The system implements feedback control by continuously monitoring the positions of swarm robots and dynamically adjusting light beam direction based on real-time data. This ensures that light beams accurately reach target points without exceeding them, maintaining high manufacturing quality through adaptive control mechanisms.
Solution Approach 2:
The light control system is made dynamic by using mobile swarm robots that can change positions and orientations in real-time. This dynamic configuration allows the system to adapt to different manufacturing requirements and precisely control light beam paths, preventing quality issues while maintaining flexibility.
3Manufacturing precision
If multiple swarm robots are used to modulate light beams, then light beam direction precision is improved, but the coordination complexity between robots increases
Solution Approach 1:
Each swarm robot is designed as a multi-functional unit that can perform both position adjustment and light beam modulation. This universality reduces the need for separate specialized components and simplifies the overall coordination architecture, as each robot independently handles multiple tasks within its operational domain.
Solution Approach 2:
The swarm robots operate with a degree of autonomy, making local decisions about light beam modulation based on their individual positions and sensor inputs. This self-service capability reduces the burden on central coordination systems and simplifies inter-robot communication requirements while maintaining precise collective control.
