Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly methods are used for cartridge components, then flexibility and adaptability are maintained, but manufacturing efficiency and productivity are reduced due to the small and fragile nature of components
Solution Approach 1:
The assembly system is divided into multiple specialized assembly cells (first assembly cell for base assembly, second assembly cell for cartridge assembly, third assembly cell for filling) that work in sequence. Each cell handles specific tasks, allowing parallel processing and improved overall productivity while managing complexity through functional decomposition.
Solution Approach 2:
A transfer apparatus acts as an intermediary mechanism between assembly cells, automatically transporting partially-assembled cartridges from one cell to the next. This mediator handles the complexity of coordination and material flow, enabling each assembly cell to focus on its specific task without direct interference from other cells.
2Manufacturing precision
If automated assembly systems are implemented, then manufacturing precision and repeatability are improved, but device complexity and initial manufacturing cost increase
Solution Approach 1:
Components are pre-positioned and pre-assembled in earlier stages before being transferred to subsequent assembly cells. For example, the base is pre-assembled with certain components in the first assembly cell before the cartridge is attached in the second cell, ensuring precision is built incrementally throughout the process.
Solution Approach 2:
Manual mechanical assembly operations are replaced with automated mechanisms including robotic transfer apparatus, ultrasonic welding systems, and computer-controlled positioning systems. These automated systems provide consistent precision while managing complexity through standardized interfaces and control protocols.
3Manufacturing precision
If components are assembled in sequence through multiple cells, then manufacturing precision is improved, but assembly time and production cycle duration increase
Solution Approach 1:
The assembly process is designed as a continuous flow where transfer apparatus continuously moves components between assembly cells without idle waiting time. Multiple assembly cells operate in parallel on different components simultaneously, maintaining continuous productive action throughout the system and reducing overall cycle time despite the multi-step process.
Solution Approach 2:
Preparation and pre-assembly operations are performed in advance in earlier assembly cells so that when components reach subsequent cells, they are ready for final assembly operations. This eliminates setup and preparation time during the critical path of the assembly process, reducing total cycle time while maintaining precision.
