Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If in-service test plugs are designed for specific matching switch configurations, then they can provide accurate measurements for those switches, but they become useless when new switches or switches with varying sizes are introduced
Solution Approach 1:
The test plug is divided into multiple individual modules, each designed to interface with specific switch types. These modular components can be selectively assembled to match different switch configurations, allowing the system to maintain measurement precision while adapting to various switch sizes and types.
Solution Approach 2:
The test plug system is designed with universal adaptability through its modular architecture. By providing a set of standardized modules that can be combined in different configurations, the system can interface with multiple switch types and sizes, making it versatile across different applications while maintaining accurate measurement capabilities.
2Ease of manufacture
If test plugs are designed with fixed configurations, then they are simpler to manufacture, but they cannot be easily reconfigured to match various test switch configurations
Solution Approach 1:
The test plug is divided into multiple individual modules, each designed to interface with specific switch types. These modular components can be selectively assembled to match different switch configurations, allowing the system to maintain measurement precision while adapting to various switch sizes.
Solution Approach 2:
The test plug system transitions from a fixed configuration to a dynamic, reconfigurable structure. Modules can be added, removed, or rearranged to match different switch configurations, enabling the system to adapt to varying test requirements while maintaining standardized manufacturing processes for each module.
3Adaptability or versatility
If test plugs are made modular with stackable modules, then they can be easily adapted to multiple configurations, but the device complexity increases
Solution Approach 1:
The test plug is divided into multiple individual modules, each designed to interface with specific switch types. These modular components can be selectively assembled to match different switch configurations, allowing the system to maintain measurement precision while adapting to various switch sizes.
Solution Approach 2:
Multiple standardized modules are combined through stacking to create a complete test plug assembly. This merging of simple, repeatable units provides configurational flexibility while avoiding the complexity of designing entirely different plugs for each application.
