Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sliding contacts are used to connect and disconnect electrical apparatus, then the operation is simple and continuous, but significant pressure is required which is not compatible with smooth sliding
Solution Approach 1:
The connection process is divided into three distinct operating areas: first operating area for simultaneous connection to both power source and control equipment, second operating area for connection to control equipment only, and third operating area for complete disconnection. This segmentation allows the system to transition through intermediate states without requiring continuous pressure during sliding, as the movable support is guided to specific positions where contacts are made or broken in a controlled sequence.
Solution Approach 2:
A movable support with guided movement introduces an intermediary mechanism between the sliding action and the contact points. This movable support carries the poles for the second line and is guided to move in a controlled manner, allowing the system to transition between connection states without requiring high pressure during the sliding phase. The guided movement ensures proper alignment and contact timing.
2Adaptability or versatility
If male poles of different lengths are used to achieve sequential connection, then the intermediate position allows disconnection from power source while maintaining connection to control equipment, but the sliding operation becomes incompatible with the required contact pressure
Solution Approach 1:
The system uses a movable support with guided movement that dynamically transitions between three operating areas. The movable support carries the poles and moves in a controlled sequence, allowing the system to adapt its connection state dynamically. The guided movement ensures that contacts are made or broken at the appropriate times during the transition, providing versatility in connection states while maintaining smooth operation.
Solution Approach 2:
The poles are pre-configured with different lengths and positioned on the movable support and stationary cabinet respectively. The male poles of the second line are longer than those of the first line, which is predetermined to enable the sequential connection behavior. This preliminary configuration allows the system to automatically achieve the desired connection states as the movable support transitions through the three operating areas.
3Reliability
If significant pressure is applied to ensure good contact quality, then contact reliability is improved, but the sliding operation becomes difficult and the intermediate position cannot be maintained
Solution Approach 1:
The connection process is segmented into three distinct operating areas where contact quality is ensured at each stage without requiring continuous high pressure during sliding. In the first operating area, both lines are connected; in the second operating area, only the second line remains connected; and in the third operating area, both lines are disconnected. This segmentation allows reliable contacts to be made at specific positions rather than requiring pressure throughout the entire sliding motion.
Solution Approach 2:
The movable support acts as an intermediary that guides the transition between connection states. It carries the poles for the second line and is guided to move in a controlled manner, ensuring proper alignment and contact timing. This intermediary mechanism allows the system to maintain reliable contacts at specific operating positions while avoiding the need for continuous high pressure during the sliding transition.
