Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pressing member (piston) is inserted into a cylindrical member (syringe) with viscous dental material, then the viscous dental material can be extruded, but the structure becomes complicated and bulky

Engineering Contradiction:
Improveextrusion of viscous dental materialVSAvoidpackaging body structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention removes the pressing member (piston) from the packaging body, extracting the complex extrusion mechanism. The viscous dental material is instead extruded by collapsing the container itself through compression forces applied to the container body, eliminating the need for separate pressing components while maintaining the extrusion function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the container body and the pressing function into a single integrated structure. The container walls themselves perform both containment and extrusion functions when compressed, combining what were previously separate components (container + piston) into one unified packaging body.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a pressing member (piston) is inserted into a cylindrical member (syringe) with viscous dental material, then the viscous dental material can be extruded, but productivity decreases and waste increases

Engineering Contradiction:
Improveextrusion of viscous dental materialVSAvoidmanufacturing efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

By removing the pressing member and associated threading mechanisms, the manufacturing process is simplified. The container can be produced more quickly without the need to assemble and thread complex piston assemblies, directly improving production speed and productivity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If a pressing member (piston) is inserted into a cylindrical member (syringe) with viscous dental material, then the viscous dental material can be extruded, but the structure becomes bulky

Engineering Contradiction:
Improveextrusion of viscous dental materialVSAvoidpackaging body size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

Removing the pressing member eliminates the need for additional space required for piston assembly, threading mechanisms, and associated components. This reduction in parts directly decreases the overall volume and bulk of the packaging body while maintaining the essential extrusion capability through container compression.

Inventive Principle:
Principle #2Taking out (Extraction)
