Solution Overview
Problem
Current solutions for regulating electric actuators in networks using 0-10 Vdc and/or PWM commands face challenges such as the need for stabilized and boosted command signals, lack of continuity in regulation, and inability to manage emergencies or remodulate command signals according to operational requirements.
Innovation Solution
An aggregated device with a potentiometer and switching element that can switch between manual and external regulation modes, providing adjustable 0-10 Vdc and/or PWM commands, and acting as an emergency bypass to ensure continuous regulation and adapt to different operational needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a basic 0-10 Vdc command is used to control EC motors, then installation is simplified, but the command signal lacks stabilization and boosting capability for network management
Solution Approach 1:
The patent introduces an intermediary device between the control system and EC motors that acts as a signal booster and stabilizer. This intermediary takes the basic 0-10 Vdc command signal and amplifies/boosts it to provide stable control across the network, resolving the contradiction between installation simplicity and signal reliability.
2Ease of operation
If known regulation solutions are used, then single devices can be managed, but continuity of regulation command cannot be ensured in case of failures
Solution Approach 1:
The patent implements beforehand cushioning by incorporating redundant regulation pathways and emergency bypass circuits that activate automatically upon detecting failures. This ensures continuity of regulation commands even when primary control paths fail, addressing the reliability issue while maintaining ease of operation.
3Device complexity
If fixed regulation modes are used, then device structure remains simple, but adaptability to different operational requirements is limited
Solution Approach 1:
The patent applies dynamics by implementing switchable regulation modes that allow the system to transition between different operational states (manual/automatic, normal/emergency) based on requirements. This dynamic adaptability is achieved through switching elements that reconfigure the circuit topology without fundamentally complicating the device structure.
4Adaptability or versatility
If external regulation devices are connected, then command signals can be received from external sources, but the ability to remodulate and amplify commands according to operational needs is lost
Solution Approach 1:
The patent merges multiple functions (signal reception, amplification, remodulation, and emergency bypass) into a single integrated device. This combining of functions allows external command signals to be received while simultaneously providing signal processing capabilities like amplification and remodulation, without proportionally increasing device complexity.
