Solution Overview
Problem
Current automated solutions for dispensing liquid solutions in laboratories lack precision in controlling pH and temperature, leading to potential cross-contamination and inefficiencies in the preparation process, as they fail to accurately measure and regulate these critical parameters.
Innovation Solution
An automated solution dispenser with a mixing chamber, controllable inlet and outlet ports, sensors for pH and temperature monitoring, and a controller that manages the dispensing of components, agitation, and cleaning cycles, ensuring precise control over pH, temperature, and chemical composition, while preventing cross-contamination through automated cleaning and drying processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated solution dispensing is implemented, then productivity and efficiency are improved, but measurement precision and control accuracy of pH and temperature may deteriorate
Solution Approach 1:
The system incorporates pH sensors and temperature sensors that continuously monitor the solution characteristics and provide feedback to the controller. The controller adjusts the dispensing process based on this feedback, ensuring precise control of pH and temperature while maintaining automated high-speed operation. This closed-loop control system resolves the contradiction by enabling both automation and precision.
Solution Approach 2:
Manual mechanical control of solution preparation is replaced with automated electronic control systems that use sensors and controllers to precisely manage pH and temperature. The electronic control system can achieve finer control accuracy than manual operations while maintaining high productivity through automation.
2Reliability
If automated cleaning cycles are implemented, then cross-contamination is reduced, but device complexity and time consumption increase
Solution Approach 1:
The system performs cleaning automatically without requiring external intervention. The cleaning cycle is initiated and executed by the system itself, using automated dispensing of cleaning agents and automated drying processes. This self-service approach ensures consistent cleaning quality while minimizing the need for complex external cleaning infrastructure.
Solution Approach 2:
The cleaning process is integrated into the continuous operation cycle, allowing the system to clean between batches without significant interruption to overall productivity. The automated cleaning system operates continuously when needed, maintaining reliability while managing complexity through integration rather than separate standalone systems.
3Measurement precision
If multiple sensors and control mechanisms are added, then measurement and control precision are improved, but device complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions: it manages the dispensing process, monitors pH and temperature readings from sensors, controls the cleaning cycle, and coordinates the drying process. By making the controller multi-functional, the system achieves high measurement and control precision without proportionally increasing overall device complexity, as one component handles multiple tasks.
Solution Approach 2:
The pH sensor, temperature sensor, controller, and cleaning system are integrated into a unified automated solution preparation system. Rather than operating as separate independent systems, these components are merged and coordinated by a single controller, achieving precise multi-parameter control while managing complexity through integration.
