Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If accessories are wired independently by means of one or more buses for various functions, then each accessory can be connected to supply and signal transmission, but the system complexity increases and wiring errors become more frequent
Solution Approach 1:
The patent combines multiple independent wiring buses into a single integrated wiring support structure. The terminal board integrates supply buses (L1, L2, L3, N) and signal buses (A1, A2, etc.) into one unified component, eliminating the need for separate buses for each accessory function. This merging reduces wiring complexity while maintaining the ability to connect multiple accessories simultaneously.
Solution Approach 2:
The wiring support is designed as a universal interface that can accommodate multiple types of accessories (auxiliary contacts, servo actuators, voltage relays, temperature sensors) through a single standardized connection system. The terminal board provides multiple terminals that can be configured for different functions, allowing one wiring support structure to serve multiple purposes and connect various accessory types without requiring separate wiring arrangements for each.
2Adaptability or versatility
If multiple auxiliary cables are used for supply and signal transmission, then all accessories can be powered and controlled, but the risk of wiring errors and maintenance costs increase
Solution Approach 1:
Multiple auxiliary cables are merged into a single wiring support assembly where all connections are made at one centralized terminal board. This consolidation reduces the number of separate cable routing paths and connection points, thereby reducing the probability of wiring errors. The integrated structure ensures that all accessories share a common, standardized connection interface, improving reliability.
Solution Approach 2:
The wiring support is pre-configured with predetermined connection paths and terminals before installation. The terminal board comes with pre-arranged wiring configurations for different accessory types, allowing installers to simply connect accessories to the pre-defined terminals without having to plan complex wiring routes. This preliminary preparation reduces wiring errors and simplifies installation.
3Extent of automation
If electronic interface units are used to recognize and control accessories, then accessories can be managed centrally, but the system requires auxiliary supply and becomes less applicable to passive accessories
Solution Approach 1:
The wiring support enables accessories to self-configure and self-identify through their physical connection to the terminal board. Each accessory connects to predetermined terminals that automatically establish the correct electrical connections without requiring electronic recognition or configuration. This self-service approach allows passive accessories (like auxiliary contacts) to function without needing power or electronic interface units, expanding applicability while maintaining centralized management through the physical wiring structure.
