Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional position fixation methods are used in 3D printing, then the fixation system is simple to manufacture, but printing errors and size differences of up to 0.1 mm occur causing positioning inaccuracies
Solution Approach 1:
The fixation system is divided into two separate components: a split-cast plate with recesses and a base plate with protrusions. This segmentation allows independent manufacturing and positioning of each component, enabling compensation for printing errors while maintaining manufacturing simplicity.
Solution Approach 2:
The protrusions on the base plate act as intermediary elements that fit into the recesses of the split-cast plate. This intermediary mechanism provides precise positioning and compensates for size differences and printing errors without requiring complex fixation procedures.
2Manufacturing precision
If direct contact between split-cast plate and base plate is used, then the structure is simple, but positioning consistency is compromised due to manufacturing variations
Solution Approach 1:
The recesses and protrusions are pre-formed during the 3D printing process with predetermined geometries. This preliminary action ensures that when the components are assembled, the positioning is automatically consistent without requiring additional adjustment or complex assembly procedures.
3Productivity
If plaster is used for articulation, then the articulation process is traditional and well-established, but the process is time-consuming and requires additional materials
Solution Approach 1:
The invention extracts and eliminates the plaster material from the articulation process. The direct mechanical connection between the split-cast plate and base plate through protrusions and recesses allows for plaster-free articulation, significantly reducing material usage and simplifying the process.
4Manufacturing precision
If the split-cast plate is directly fixed to the base plate without profiles, then the structure is simpler, but vertical and horizontal positioning cannot be ensured
Solution Approach 1:
Instead of making the entire plate structure complex, the invention applies localized quality enhancements through protrusions and recesses at specific contact points. These localized features provide precise positioning control without requiring complex overall structures.

AI summary
The present invention relates to a fixation system (1) for fixing a dental model, comprising a split-cast plate (10) which can be arranged in an articulator and is intended to receive a dental model, and a base plate (11) which can be connected to the split-cast plate (10), wherein a plurality of recesses (100) are formed on the split-cast plate (10) and a plurality of bulges (110) are formed on the base plate (11) which correspond at least in sections to the recesses (100) - or vice versa - for fixing the position of the split-cast plate (10) in the horizontal (HE) and vertical plane (VE). The present invention is characterized in that the base plate (11) comprises at least one first oblique profile (111) which runs around the edge at least in some areas and is beveled outwards, and the split-cast plate (10) has at least one first oblique profile (111) which runs around the edge at least in some areas and is beveled outwards.a second inclined profile (101) which is bevelled outwards and designed to correspond to the first inclined profile (111), wherein at least one first support profile (112) is formed on the base plate (11) and runs around the edge of the base plate (11) at least in some areas, and at least one second support profile (103) is formed on the split-cast plate (10) which runs around the edge of the base plate (11) at least in some areas and is designed to correspond to the first support profile (112) for resting on the first support profile (112), wherein the first support profile (112) and/or the second support profile (103) is/are designed such that one or more diagonal, oblique and/or horizontal gaps (12, 13, 14) are formed between the split-cast plate (10) and the base plate (11).
