Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a water-cooling system is used to cool the digital nozzle, then the nozzle temperature is reduced, but the temperature becomes unstable leading to chromatic aberration
Solution Approach 1:
The cooling system is divided into two independent parts: water-cooling horizontal bars for heat dissipation and constant-temperature horizontal bars for temperature stabilization. This segmentation allows each component to perform its specific function optimally - water cooling removes excess heat while the constant-temperature section maintains stable operating conditions, preventing chromatic aberration caused by temperature fluctuations
Solution Approach 2:
The constant-temperature horizontal bars act as an intermediary between the water-cooling system and the digital nozzle. These bars receive cooling from the water-cooling system and transfer stabilized cooling to the nozzle, mediating the temperature control process to ensure both effective cooling and temperature stability
2Temperature
If continuous cooling is applied to the nozzle, then temperature is maintained, but printing quality deteriorates due to unstable temperature
Solution Approach 1:
Different sections of the cooling device have different functional qualities: the water-cooling horizontal bars provide active cooling with higher cooling power, while the constant-temperature horizontal bars provide temperature stabilization. This local differentiation of cooling characteristics ensures that the nozzle receives appropriately varied cooling zones, maintaining printing quality by preventing temperature-induced chromatic aberration
