Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly is used for medicine mixer, then flexibility and adaptability are maintained, but working efficiency is low and productivity is limited
Solution Approach 1:
The assembly machine divides the medicine mixer assembly process into multiple independent workstations (mounting devices for cup, plug, clip, needle, coverplate, and soldering) arranged around a rotatable dividing table. Each workstation performs a specific assembly operation, allowing parallel processing and improving overall productivity while keeping each individual station relatively simple.
Solution Approach 2:
The rotatable dividing table serves multiple functions: it positions components at different workstations, enables sequential assembly operations, and facilitates automated material handling. This single multi-functional device replaces what would otherwise require multiple separate assembly machines, improving productivity without proportionally increasing device complexity.
2Productivity
If automated assembly equipment is used, then productivity and working efficiency improve, but device complexity increases and existing equipment cannot assemble medicine mixer
Solution Approach 1:
The patent combines multiple mounting devices (for cup, plug, clip, needle, coverplate, and soldering) and a rotatable dividing table into a single integrated assembly machine. This merging of functions into one coordinated system achieves high automated assembly efficiency while avoiding the need for multiple separate complex devices.
Solution Approach 2:
The rotatable dividing table provides dynamic positioning, allowing the assembly machine to automatically transition between different workstations and adapt to various assembly sequences. This dynamic mechanism enables flexible automated assembly without requiring rigid, overly complex fixed positioning systems.
3Manufacturing precision
If manual assembly is used, then device complexity is low, but manufacturing precision and quality control do not meet medical criteria
Solution Approach 1:
The automated assembly machine performs precise positioning and assembly operations without human intervention. The mounting devices automatically align and secure components (cup, plug, clip, needle, coverplate) with high precision, ensuring consistent quality that meets medical criteria while eliminating manual assembly errors.
Solution Approach 2:
The patent replaces manual mechanical assembly with automated mounting devices that use controlled mechanical movements for precise component placement. The soldering device provides automated thermal processing with consistent parameters, ensuring high manufacturing precision and quality control without the variability of manual operations.
4Productivity
If automated assembly with multiple mounting devices is implemented, then productivity improves, but the number of components and device complexity increase
Solution Approach 1:
The assembly machine segments the assembly process into distinct operations (mounting cup, plug, clip, needle, coverplate, soldering) performed at separate workstations around the dividing table. This segmentation allows each component to be handled by a specialized mounting device, improving assembly output while organizing the complexity into manageable modular units.
