Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In three-dimensional shaping, the posture of a shaping table is unstable due to thermal expansion during heating, leading to prolonged adjustment times and reduced shaping accuracy.
Innovation Solution
A shaping stage with a cooling unit to stabilize the posture adjusting unit, combined with a heating unit to maintain the shaping table at a predetermined temperature, and a detecting unit to ensure parallelism between the nozzle and shaping surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the shaping table is heated to maintain temperature during three-dimensional shaping, then the shaping temperature is maintained, but the posture adjusting unit undergoes thermal expansion causing posture instability and prolonged adjustment time
Solution Approach 1:
The system divides the thermal management into separate zones: the shaping table is heated while the posture adjusting unit is cooled independently. This segmentation allows each component to maintain its optimal temperature condition without interfering with the other, resolving the thermal conflict between heating requirements and dimensional stability
Solution Approach 2:
A cooling unit acts as an intermediary between the heated shaping table and the posture adjusting unit. This intermediary cooling system prevents thermal expansion of the posture adjusting unit by actively removing heat, thereby maintaining posture stability despite the elevated temperature of the shaping table
2Manufacturing precision
If the posture of the shaping table is adjusted manually after thermal expansion occurs, then the posture can be corrected, but the adjustment time is significantly prolonged
Solution Approach 1:
The cooling unit is activated before and during the heating process to prevent thermal expansion of the posture adjusting unit in advance. By maintaining the posture adjusting unit at a stable temperature beforehand, the system eliminates the need for time-consuming manual adjustments after heating begins
Solution Approach 2:
The system replaces manual mechanical adjustment with an active thermal control system. Instead of manually correcting posture after thermal expansion occurs, the cooling unit continuously maintains dimensional stability, substituting active thermal management for passive mechanical correction
