Solution Overview

Problem

The manufacturing of dental components, such as dental prostheses, is labor-intensive and prone to errors due to the numerous complex manual steps involved, leading to high work effort and potential defects.

Innovation Solution

The method involves additive manufacturing (3D printing) to create a physical model from a virtual 3D model, embedding it in an investment material, removing it to form a negative mold, inserting raw material, and producing the dental component within the mold, which can be partly automated to reduce human errors and save costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual methods are used to manufacture dental components, then flexibility and adaptability are maintained, but work effort increases and error sources multiply

Engineering Contradiction:
Improvework effortVSAvoidprocess complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent uses digital copying (3D scanning and virtual modeling) to create precise digital replicas of the patient's dentition and dental components. This digital model is then used to guide the entire manufacturing process, eliminating the need for multiple manual copying steps and reducing both work effort and error sources while maintaining full adaptability to the patient's specific anatomy.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces manual mechanical operations with automated systems. The 3D scanner captures dental impressions digitally, CAD software performs virtual modeling and planning, and the 3D printer executes manufacturing based on digital instructions. This substitution of mechanical manual processes with digital-automated systems reduces work effort and minimizes human error while preserving the ability to customize each component.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If multiple manual steps are used in dental component manufacturing, then customization is possible, but defects can occur at many points

Engineering Contradiction:
Improvedefect rateVSAvoidmanual operation requirements
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent creates a single authoritative digital model that serves as the master copy for the entire manufacturing process. This digital replica eliminates the need for multiple physical copies and manual transfer steps, each of which could introduce defects. The digital model can be stored, reviewed, and reproduced indefinitely without degradation or introduction of errors.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces manual operations with automated digital processes. The 3D scanner, CAD software, and 3D printer work together as an integrated automated system that follows precise digital instructions. This eliminates human variability and error sources associated with manual operations while maintaining the ability to produce customized components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Loss of substance

If traditional manufacturing methods are used, then material storage is required, but storage costs and material waste increase

Engineering Contradiction:
Improvematerial wasteVSAvoidadditive manufacturing adoption
Core Design Contradiction:
Loss of substanceVSExtent of automation

Solution Approach 1:

The patent changes the fundamental manufacturing parameter from subtractive (removing material) to additive (depositing material layer by layer). Traditional methods require storing large amounts of material and removing excess, while additive manufacturing only uses the exact amount of material needed for each component. This parameter change eliminates material waste and storage requirements while embracing automation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent eliminates the need to store and manage material inventory by producing components on-demand through additive manufacturing. Instead of discarding excess material or managing storage, the system recovers the benefits of automation by manufacturing only what is needed, when it is needed, using precise digital models to guide material deposition.

Inventive Principle:
Principle #34Discarding and recovering
