Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single reservoir embalming machine is used, then the device complexity is reduced, but the manufacturing precision and consistency of fluid distribution deteriorate
Solution Approach 1:
The embalming machine is divided into multiple independent fluid reservoirs (first reservoir for surfactants, second reservoir for preservative chemicals) with separate control systems. Each reservoir can be independently filled, controlled, and monitored, allowing precise control over different fluid types while maintaining overall system manageability.
Solution Approach 2:
The system incorporates variable speed control for the centrifugal pump, allowing dynamic adjustment of fluid flow rates and pressures. The controller can modify pump speed in real-time based on procedural requirements, enabling precise control over fluid distribution characteristics throughout the embalming process.
2Ease of operation
If operator adjustments are used during embalming, then the ease of operation is improved, but the measurement precision and control over fluid displacement deteriorate
Solution Approach 1:
The system incorporates pressure sensors and flow meters that continuously monitor fluid pressure and flow rate, providing real-time feedback to the controller. This allows the system to automatically adjust pump speed and valve positions to maintain precise control over fluid displacement, eliminating the need for manual operator adjustments while improving measurement accuracy.
Solution Approach 2:
Manual operator adjustments are replaced with an automated electronic control system that uses sensors, controllers, and actuators to precisely regulate fluid flow. The electronic control system provides more accurate and consistent control compared to manual mechanical adjustments, while maintaining ease of operation through user-friendly interfaces.
3Device complexity
If a single reservoir is used for fluid solutions, then the device complexity is reduced, but the adaptability for different embalming procedures deteriorates
Solution Approach 1:
The single reservoir is segmented into multiple specialized reservoirs, each designed to hold specific fluid types (surfactants, preservative chemicals, etc.). This segmentation allows the system to adapt to different embalming procedures by selectively using appropriate reservoirs and fluid combinations, while each reservoir remains independently manageable.
Solution Approach 2:
The multi-reservoir system is designed with universal compatibility, where each reservoir can be independently connected to the pump system and controlled through a unified interface. The system can accommodate different fluid types and procedural requirements using the same basic hardware platform, providing versatility without requiring multiple specialized machines.
