Solution Overview
Problem
Existing protective devices for electrical systems are complex and prone to user input errors, making them difficult to operate quickly and efficiently.
Innovation Solution
The protective device is designed with functional groups, allowing for the assignment of function modules, which reduces the number of user inputs required by limiting connections between specific types of function modules and measurement inputs, thereby simplifying the configuration and reducing error probability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If protective devices allow flexible assignment of function modules to measurement inputs, then the device can be adapted to various system topologies, but the complexity of device setting increases and user input errors become more frequent
Solution Approach 1:
The patent segments the function modules into two distinct groups: switch-specific function modules and protection-specific function modules. This segmentation allows each group to be configured independently with predetermined connection rules, reducing the complexity of device setting while maintaining adaptability to various system topologies.
Solution Approach 2:
The patent creates universal connection rules that apply to all function modules within each group. Switch-specific function modules universally connect to switches, while protection-specific function modules universally connect to measurement inputs. This universal approach simplifies configuration across different system topologies without requiring complex individual settings for each module.
2Manufacturing precision
If protective devices require detailed configuration of each function module's connections, then precise control is achieved, but the time required for device setting increases
Solution Approach 1:
The patent performs preliminary action by pre-defining the connection relationships between function module groups and measurement inputs. The assignment of switch-specific function modules to switches and protection-specific function modules to measurement inputs is established in advance through structured grouping, eliminating the need for time-consuming individual configuration during device setting while maintaining precise control over connections.
3Adaptability or versatility
If protective devices allow unrestricted assignment of function modules, then configuration flexibility is maximized, but the probability of user input errors increases
Solution Approach 1:
The patent applies preliminary anti-action by preventing erroneous assignments before they can occur. The structured grouping system with distinct switch-specific and protection-specific function module groups establishes predetermined valid connection paths, automatically preventing invalid assignments and reducing the probability of user input errors while maintaining configuration flexibility within the structured framework.
