Solution Overview

Problem

Conventional electrical systems with control channels experience significant delays in responding to issues like overcurrent conditions due to lack of efficient communication and coordination between control channels, leading to potential hardware wastage and inefficiencies.

Innovation Solution

A system where each control channel is connected to adjacent channels via communication lines and a controller that assigns grouping information, allowing them to function in unison by selectively communicating within designated groups, using resistors to manage check voltages and prevent unnecessary communication with non-group channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If control channels use dedicated commands or master-slave linkage to coordinate, then control channels can work together in unison, but there is a considerable delay in responding to problems

Engineering Contradiction:
Improvecoordination of control channelsVSAvoidresponse delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical/electrical communication methods (dedicated commands, master-slave linkage) with optical communication using light-emitting diodes (LEDs) and photodetectors. This substitution enables near-instantaneous signal transmission between control channels, eliminating the considerable delay inherent in conventional electrical signaling methods while maintaining reliable coordination.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces optical intermediaries (LEDs and photodetectors) between control channels to facilitate communication. These intermediaries convert electrical signals to optical signals and back, enabling rapid information exchange without the delay of direct electrical connections, thus improving response time while preserving coordination reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If control channels are grouped to control heavy loads, then hardware utilization is improved, but communication complexity between channels increases

Engineering Contradiction:
Improvehardware utilizationVSAvoidcommunication complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the communication function from the main control logic by implementing dedicated optical communication pathways between control channels. This separation allows control channels to communicate status and coordination information directly through LEDs and photodetectors without burdening the main control system, thereby reducing overall communication complexity while enabling flexible hardware grouping for heavy load control.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A system (100) for dynamically controlling the functionality of control channels (101) in an electrical system includes a plurality of control channels, each operatively connected to at least one state change device (351) connected to an electrical component. Each control channel (101) is operatively connected to at least one adjacent control channel by a control channel communication line (107). Each control channel (101) is configured to store grouping information of the state change device (351). A controller (103) is operatively connected to each control channel (101) such that each control channel can receive the grouping information from the controller (103). The controller (103) is configured to selectively send grouping information to allow each control channel (101) to directly communicate with adjacent control channels within their respective grouping such that each control channel (101) in a grouping functions together in unison when the at least one state change device (351) in a grouping changes state.
