Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used to open covers and replace connectors on chemical containers, then operational flexibility is maintained, but the risk of toxic substance leakage and safety accidents increases
Solution Approach 1:
The system performs operations automatically without requiring continuous human intervention. The robotic arm autonomously positions itself, the cover-opening device automatically opens covers, and the liquid-pumping device self-regulates to replace connectors, making the system serve itself through automated control mechanisms
Solution Approach 2:
Manual mechanical operations are replaced with an automated robotic system comprising a robotic arm, cover-opening device with screw motors, and liquid-pumping device. This substitution eliminates direct human contact with hazardous chemicals while maintaining operational capability through automated mechanical systems
2Reliability
If automated cover-opening and connector-replacing device is implemented, then safety against toxic substance leakage is improved, but device complexity increases
Solution Approach 1:
The automated system is divided into distinct functional modules: a robotic arm for positioning, a cover-opening device with screw motors for opening covers, and a liquid-pumping device for connector replacement. Each module operates independently but coordinates through the control unit, allowing complex functionality to be achieved through simpler, modular components
Solution Approach 2:
The robotic arm and associated devices are designed to perform multiple functions - positioning, cover opening, connector replacement, and liquid pumping - all through a single integrated automated system. This multi-functionality reduces the need for multiple separate devices, managing complexity while achieving comprehensive automation
3Measurement precision
If precise positioning and synchronized movement are achieved through lifting device and rotary motor, then operational accuracy is improved, but device complexity and energy consumption increase
Solution Approach 1:
The system uses image capture devices to detect the positions of covers and connectors on chemical containers. This visual feedback is processed by the control unit to automatically adjust the robotic arm's positioning and the lifting device's height, achieving precise positioning through closed-loop control rather than complex mechanical positioning systems
Solution Approach 2:
The control unit acts as an intermediary between the image capture devices and the robotic arm/lifting device. It processes visual information and translates it into coordinated movement commands, simplifying the positioning system by using software-based coordination rather than complex mechanical linkages
