Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual connection methods are used for voltage measuring connectors, output cables, and fluid supply tubes, then the activation process can be performed with simple equipment, but the workability deteriorates and the process becomes time-consuming
Solution Approach 1:
The activation apparatus is divided into multiple independent connecting units: a connector connecting unit for voltage measuring connectors, an output cable connecting unit for output cables, and a fluid supply tube connecting unit for fluid supply tubes. Each unit operates independently to connect its specific component, thereby improving workability while maintaining manageable equipment complexity through functional segmentation.
2Productivity
If manual connection of connectors and cables is performed, then the equipment structure remains simple, but the connection time increases substantially
Solution Approach 1:
The connecting units are pre-positioned and configured before the activation process begins. The connector connecting unit, output cable connecting unit, and fluid supply tube connecting unit are all ready to connect their respective components simultaneously or in rapid succession, eliminating the time-consuming sequential manual connection process and substantially reducing activation time.
3Reliability
If manual connection of output cables is performed, then the equipment remains simple, but safety risks increase due to potential electric shocks
Solution Approach 1:
The output cable connecting unit serves as an intermediary between the operator and the electrical components. It includes specialized connection mechanisms that safely interface with output terminals, isolating the operator from direct exposure to electrical hazards while maintaining equipment structure at a manageable level through dedicated connection hardware.
4Reliability
If manual connection of fluid supply tubes is performed, then the equipment structure remains simple, but air-tightness cannot be ensured and stack damage may occur
Solution Approach 1:
The fluid supply tube connecting unit replaces manual mechanical connection with an automated or assisted connection mechanism that ensures proper alignment and secure attachment. This substitution guarantees air-tightness by eliminating human error in connection positioning while maintaining equipment structure through dedicated connection hardware designed for reliable fluid supply.
