Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If material powder is spread to the entire space of the molding chamber, then the molding process can be completed, but the amount of material powder supplied increases and the work burden increases
Solution Approach 1:
The molding chamber is divided into a molding space (where the object is formed) and a non-molding space (surrounded by the elastic member). This segmentation allows material powder to be supplied only to the necessary molding space, reducing the total quantity of powder required while ensuring complete molding process execution.
Solution Approach 2:
The elastic member can dynamically change the volume of the non-molding space by extending or contracting. This dynamic adjustment optimizes the distribution between molding and non-molding spaces, ensuring that material powder is supplied efficiently only where needed, thereby reducing the overall amount of powder supplied.
2Quantity of substance
If the amount of material powder supplied is reduced, then the work burden decreases, but the structural integrity may be compromised leading to powder leakage
Solution Approach 1:
The elastic member acts as a flexible boundary that can dynamically adjust to maintain structural integrity. By extending or contracting, it ensures that the molding space is properly contained without requiring excessive material powder, thus maintaining reliability while reducing powder quantity.
Solution Approach 2:
The elastic member changes the volume parameter of the non-molding space dynamically. This parameter change allows the system to maintain structural integrity at different stages of the molding process while optimizing the amount of material powder supplied, preventing leakage without compromising reliability.
3Temperature
If the volume of non-molding space is increased, then heat-induced deformation can occur, but if reduced, then powder containment may be affected
Solution Approach 1:
The elastic member dynamically adjusts the volume of the non-molding space based on process requirements. During heating phases, it can contract to minimize heat-induced deformation, while during powder containment phases, it extends to ensure proper containment, thus balancing temperature control with manufacturing precision.
Solution Approach 2:
The flexible elastic member provides a adaptive boundary that can respond to thermal changes. It maintains powder containment through its flexible sealing capability while allowing volume adjustment to minimize exposure to heat-induced deformation, balancing both requirements effectively.

AI summary
The manufacturing device manufactures a laminate shaped object by supplying material powder to a molding chamber to form a powder layer and irradiating a surface of the powder layer with a beam to sinter the powder layer. The molding chamber has a molding space where the material powder is irradiated with the beam and the laminate shaped object is formed, and a non-molding space which is outside the molding space and in which the laminate shaped object is not formed. An elastic member is disposed in the non-molding space, and the elastic member extends or contracts to change volume along with change of a relative position of the table in a vertical direction.
