Electricity Meter Connector with Neutral Conductor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for electricity meters are not optimally adapted for measuring single-phase alternating current, leading to inefficiencies and increased size and material costs, as they are primarily designed for three-phase current.
Innovation Solution
A connection device with a neutral conductor connection element integrated into the elongated housing, allowing contact pieces to connect either longitudinally or perpendicularly, and featuring a space-saving arrangement of current phase and neutral conductor connection elements, enabling the device to be smaller and more flexible for both single-phase and three-phase applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connection devices are designed for three-phase current with distributed connection elements, then three-phase measurement capability is achieved, but device size and material costs increase for single-phase applications
Solution Approach 1:
The connection device is designed with connection elements that can accommodate both single-phase and three-phase current measurements. The elongated housing with distributed connection elements allows the same device structure to serve multiple functions - measuring energy consumption for single-phase consumers while maintaining the capability for three-phase applications, thus achieving universality without requiring separate specialized devices
Solution Approach 2:
For single-phase applications, only the necessary connection elements are activated and used, while the other connection elements remain unused. This extraction approach allows the device to function efficiently for single-phase measurement by utilizing only the required portion of the connection elements, reducing the effective resource consumption while maintaining the physical structure for future three-phase capability
2Adaptability or versatility
If connection elements are distributed and offset in the elongated housing, then three-phase current connection is enabled, but space is wasted and material costs increase for single-phase meters
Solution Approach 1:
The connection device uses a standardized elongated housing with distributed connection elements that can serve both single-phase and three-phase applications. This universal design allows the same physical structure and material composition to be used across different application types, achieving flexibility without requiring separate specialized devices for each current type
Solution Approach 2:
The device is designed with more connection elements than needed for single-phase applications (excessive action), allowing it to handle both single-phase and three-phase currents. While this uses more materials than strictly necessary for single-phase alone, it provides the flexibility and future-proofing needed for upgraded applications, and the unused elements simply remain inactive
