Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement modules for low-voltage switchboards require multiple cables to transmit current and voltage data, leading to complex cable layouts, increased costs, and difficulties in maintenance, as they often lack integrated voltage measurement capabilities and necessitate additional connections, which complicates the determination of power consumption and monitoring.
Innovation Solution
A measurement module with an integrated analog-to-digital converter and conductive elements for both current and voltage connections, allowing simultaneous measurement and transmission of data through a single digital output cable, reducing the number of cables needed and simplifying the installation process by integrating voltage connections directly with the fuse block base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate cables are used to transmit current and voltage data from the fuse block base to the measurement receiving device, then complete measurement data can be obtained, but the cable layout becomes complex, increasing installation cost and maintenance difficulty
Solution Approach 1:
The patent combines multiple measurement data transmission functions into a single communication cable by using an analog-to-digital converter that multiplexes current and voltage signals. Instead of requiring separate cables for each parameter, the system merges all measurement data into one digital communication channel, thereby maintaining complete measurement capability while dramatically reducing cable layout complexity
Solution Approach 2:
The patent replaces the mechanical/electrical system of multiple separate analog signal cables with a digital communication system. By converting analog measurement signals to digital format and transmitting them through a single digital communication cable, the system eliminates the need for multiple analog cables, reducing physical complexity while maintaining data integrity
2Measurement precision
If additional connection means are provided in other areas of the switchboard to obtain voltage measurements, then voltage values can be obtained, but mounting difficulties increase and the layout becomes more complex
Solution Approach 1:
The measurement module is designed as a multi-functional integrated unit that can obtain both current and voltage measurements through its own built-in connections. The module universally handles multiple measurement functions without requiring separate dedicated connection points in other switchboard areas, thereby maintaining complete measurement capability while simplifying installation to a single location
Solution Approach 2:
The measurement module acts as an intermediary device that internally manages the complexity of obtaining both current and voltage measurements. Instead of requiring the installer to create separate connections in multiple areas, the module provides its own internal connection means, mediating between the fuse block base and the measurement receiving device through a single integrated interface
3Device complexity
If a measurement module without integrated voltage measurement is used, then the module structure is simpler, but additional means must be arranged to determine voltage, increasing time and resources
Solution Approach 1:
The measurement module merges voltage measurement capability with current measurement functionality in a single integrated unit. By combining these functions within the same module structure, the patent maintains relative structural simplicity while eliminating the need for separate voltage measurement arrangements, thereby reducing installation time without significantly increasing module complexity
Solution Approach 2:
The measurement module is pre-configured with built-in voltage measurement connections and an analog-to-digital converter that handles both current and voltage signals. This preliminary integration of voltage measurement capability means that during installation, no additional arrangements or modifications are needed, thereby reducing installation time and resources while maintaining a relatively simple module design
