Integrated Contactor Assembly for Electrical Panel Energy Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical panels and external programmers are limited in detecting minor faults and require multiple devices for managing electrical consumption, leading to increased complexity and cost, while current systems cannot prevent minor faults or control energy usage efficiently within electrical installations.
Innovation Solution
A compact contactor assembly integrated into an electrical panel, equipped with a measuring device, evaluation unit, and communication device, which learns consumption habits to automate energy management, detect minor faults, and adjust power supply based on occupancy and ambient temperature, allowing for centralized control and efficient energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external programmers are used to control electrical consumption, then energy management is possible, but device complexity increases and minor faults cannot be detected
Solution Approach 1:
The patent combines the programming function, measurement function, and fault detection function into a single integrated contactor assembly that is electrically positioned in the electrical panel. This merging eliminates the need for multiple separate external programmers while maintaining energy management capability and adding fault detection functionality.
Solution Approach 2:
The contactor assembly performs multiple functions: it controls electrical consumption through programming, measures electrical parameters (current, voltage, power), detects faults in the electrical installation, and provides communication interfaces. This multi-functionality replaces what previously required multiple separate devices.
2Reliability
If traditional circuit breakers and contactors are used, then major faults are detected, but minor faults cannot be prevented and control requires external devices
Solution Approach 1:
The contactor assembly continuously measures electrical parameters (current, voltage, power) and compares them against expected values to detect anomalies. This feedback mechanism enables early detection of minor faults before they escalate, while the integrated design maintains simplicity.
Solution Approach 2:
The contactor assembly autonomously monitors its own electrical installation for faults and automatically controls power distribution based on detected conditions, eliminating the need for external control devices and reducing interface complexity.
3Ease of operation
If multiple external programmers are deployed for each device, then individual control is possible, but cost increases and individual programming becomes inconvenient
Solution Approach 1:
Instead of deploying one programmer per device, the patent uses a single contactor assembly per electrical panel that can control multiple devices through its integrated programming function. This dramatically reduces the total number of programmers needed while maintaining individual device control capability through centralized management.
