Engineering Contradictions & Design Principles
Engineering 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
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.
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.
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
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.
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
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.
