Dental Aid Separation Using Auxiliary Structure Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing dental aids through deep drawing are time-consuming and require specialized skill for accurate separation of the dental aid from the deep-drawn plastic film or plate, often resulting in errors and increased production time.
Innovation Solution
A method that involves creating a digital three-dimensional working model of the jaw using biometric data, supplementing it with an auxiliary structure as an elevation or depression, and using this structure to guide the separation of the dental aid along a cutting line, allowing for reliable and efficient manual separation even by inexperienced users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual separation of the dental aid from the deep drawn plastic film is performed without auxiliary structures, then the separation process requires specialized skill and experience, but the production time is increased and errors occur more frequently
Solution Approach 1:
The auxiliary structure (e.g., separation groove, protrusion, or hole) is created in advance during the digital model design phase and incorporated into the physical working model before the deep drawing process. This preliminary action provides a pre-defined separation path that guides the cutting tool, eliminating the need for skilled manual judgment during separation and significantly reducing production time while improving accuracy.
2Productivity
If manual separation is performed by inexperienced users, then the process becomes faster, but the quality and reliability of separation deteriorates
Solution Approach 1:
The auxiliary structure acts as an intermediary element between the deep drawn plastic film and the cutting tool. It provides a physical guide (groove, protrusion, or hole) that automatically directs the cutting tool along the correct separation path, enabling inexperienced users to achieve precise separation results without requiring specialized skill or experience.
3Ease of manufacture
If no auxiliary structure is provided, then the deep drawing process is simpler, but the separation process becomes more difficult and error-prone
Solution Approach 1:
The auxiliary structure segments the working model by creating a distinct separation path (groove, protrusion, or hole) that divides the deep drawn plastic film into the dental aid and excess material. This segmentation provides a clear visual and physical guide for separation, making the operation easier and more reliable without complicating the deep drawing process itself.
