Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual removal of three-dimensional objects is used, then operator flexibility is maintained, but operator contamination occurs and production time increases
Solution Approach 1:
The detachment device performs the removal operation autonomously without requiring operator intervention. The device includes a detachment element that automatically separates the three-dimensional object from the carrier device, enabling the system to serve itself and eliminate manual handling of contaminated materials.
Solution Approach 2:
The manual mechanical removal process is replaced with an automated detachment device that uses controlled mechanical forces. The detachment element applies precise mechanical action to separate the object from the carrier, substituting human manual operation with an automated mechanical system that prevents contamination.
2Reliability
If detachment device is exposed to solidifiable material, then detachment function is maintained, but cutting edge becomes contaminated and damaged
Solution Approach 1:
The detachment element is extracted from the direct contact zone with the solidifiable material. By positioning the detachment element away from the material reservoir and designing it to only contact the solidified object during the detachment phase, the cutting edge is protected from contamination while maintaining its functional integrity.
Solution Approach 2:
The detachment operation is performed as a preliminary action after the three-dimensional object has been fully formed and solidified. This timing ensures that the detachment element only encounters the solid object rather than the liquid or gel-like solidifiable material, preventing contamination of the cutting edge during the detachment process.
3Productivity
If automated detachment is implemented, then production efficiency increases, but device complexity increases
Solution Approach 1:
The detachment device is segmented into distinct functional components: a detachment element with cutting edge, a holder for positioning the detachment element, and a drive mechanism for automated operation. This segmentation allows each component to be optimized independently while working together to achieve automated detachment, balancing functionality with manageable complexity.

AI summary
In order that an apparatus for producing a three-dimensional object by solidifying a radiation-solidifiable material, in particular layer by layer or continuously, which apparatus comprises a carrier device for holding the solidified three-dimensional object, can be improved in such a way that the production of three-dimensional objects is made easier, it is proposed that the apparatus comprises a detaching device for automatically detaching a three-dimensional object held on the carrier device.
