Solution Overview

Problem

Conventional plate denture fabrication methods face challenges in embedding reinforcing structures without compromising aesthetics and often result in strength issues, deformation, and displacement of reinforcement wires, leading to inadequate fracture resistance and aesthetic concerns.

Innovation Solution

A method involving a denture plate with a concave socket and a vertical groove, where an adhesive material is applied to both the socket and groove, allowing for simultaneous embedding and integration of a reinforcing structure and artificial teeth, enhancing strength and aesthetics by improving fracture resistance without impairing the denture's appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If reinforcing wire is embedded in the denture plate using conventional methods, then the strength of the denture is improved, but the reinforcing wire deforms and displaces during resin filling, compromising manufacturing precision

Engineering Contradiction:

Improvedenture strengthVSAvoidreinforcing wire position accuracy

Core Design Contradiction:

StrengthVSManufacturing precision

Solution Approach 1:

The reinforcing wire is pre-positioned in the denture plate before resin filling, and the plate is then flipped over to perform the filling operation. This preliminary positioning ensures the reinforcing wire maintains its intended position and shape without deformation during the resin filling process, resolving the contradiction between strength improvement and manufacturing precision

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The conventional sequence of operations is inverted: instead of filling resin first and then embedding the reinforcing wire, the reinforcing wire is embedded first and the plate is flipped over for resin filling. This inversion prevents the reinforcing wire from being displaced or deformed during the filling process, maintaining both strength and positioning accuracy

Inventive Principle:

Principle #13The other way round (Inversion)

2Strength

If reinforcing structure is embedded in the denture plate, then fracture resistance is improved, but the embedding process becomes complex and time-consuming

Engineering Contradiction:

Improvefracture resistanceVSAvoidembedding process complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The reinforcing structure is pre-positioned in the denture plate before resin filling, allowing for a systematic and organized embedding process. This preliminary arrangement simplifies the overall process by providing a clear sequence of operations and reducing the complexity of coordinating multiple steps simultaneously

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The embedding process is divided into distinct segments: first positioning the reinforcing structure, then flipping the plate, and finally performing resin filling. This segmentation of the process into manageable stages reduces overall complexity and makes the embedding procedure more controllable and efficient

Inventive Principle:

Principle #1Segmentation

3Strength

If reinforcing wire is embedded in the denture plate, then strength is improved, but the wire protrudes during resin filling causing additional finishing work

Engineering Contradiction:

Improvedenture strengthVSAvoidfinishing work requirement

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The plate is flipped over after reinforcing wire embedding and before resin filling, so that the convex surface faces downward during filling. This inversion prevents the reinforcing wire from protruding into the resin flow, eliminating the need for additional cutting and polishing operations to remove excess wire

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The plate flipping operation serves as a preliminary anti-action that prevents the reinforcing wire from protruding during resin filling. By inverting the plate before filling, the process proactively avoids the problem of wire protrusion and the subsequent need for finishing work

Inventive Principle:

Principle #9Preliminary anti-action
