Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light module output power is kept constant, then the device complexity is reduced, but the manufacturing precision deteriorates due to incomplete curing or overcuring when temperature changes
Solution Approach 1:
The light module output power is dynamically adjusted based on the detected temperature of the printing materials. The control module modifies the illumination intensity in real-time according to temperature conditions, transforming the static light output into a dynamic parameter that adapts to environmental changes, thereby maintaining consistent curing quality across varying temperatures.
Solution Approach 2:
The patent changes the parameter of light module output power based on temperature detection. When the printing materials temperature deviates from the ideal range, the control module adjusts the illumination intensity parameter accordingly, allowing the system to compensate for temperature effects without requiring complex additional hardware.
2Manufacturing precision
If the light module output power is adjusted according to temperature, then the manufacturing precision is improved, but the device complexity increases due to additional temperature sensing and control modules
Solution Approach 1:
The system implements a feedback control loop where the temperature sensing module continuously monitors the printing materials temperature, sends this information to the control module, which then adjusts the light module output power accordingly. This closed-loop feedback mechanism enables automatic compensation for temperature variations, maintaining high manufacturing precision while keeping the control logic integrated and manageable.
Solution Approach 2:
The system performs self-adjustment by automatically detecting temperature changes and modifying its own operating parameters (light output power) without requiring external intervention. The control module uses the temperature sensor data to autonomously regulate the curing process, making the system self-correcting and reducing the need for manual calibration or complex external control systems.
3Manufacturing precision
If the light module output power is adjusted according to temperature, then the manufacturing precision is improved, but the use of energy increases due to dynamic power modulation
Solution Approach 1:
The system applies partial action by adjusting the light module output power to the minimum necessary level required for effective curing at each temperature condition. Rather than maintaining constant high-power output, the system modulates the illumination intensity to match the actual curing needs, reducing energy consumption while still achieving complete and uniform curing of the printing materials.
