Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive systems face malfunctions and failures due to inadequate coordination of electrical energy information between the frequency converter and other components, leading to potential damage and inefficiencies.
Innovation Solution
The frequency converter accesses and validates information about the available electrical energy from the power supply and the energy requirements of other components through logical comparisons, ensuring compatibility and efficient operation by transitioning to appropriate system states based on plausibility checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the frequency converter operates without validating energy information, then the system can start quickly, but the drive system may suffer malfunctions and total failure due to inadequate coordination of electrical energy information
Solution Approach 1:
The patent applies preliminary action by performing energy information validation during the commissioning phase before the drive system enters regular operation. The frequency converter reads and validates energy information from the electronic nameplate during initialization, ensuring that energy availability and consumption requirements are coordinated before the system starts operating. This prevents malfunctions and total failure that would occur without such preliminary coordination of electrical energy information.
2Reliability
If the frequency converter validates energy information through logical comparison, then the drive system is protected from damage, but the commissioning process becomes more complex
Solution Approach 1:
The patent applies self-service by enabling the frequency converter to automatically read, validate, and coordinate energy information from the electronic nameplate without requiring manual intervention or external tools. The system autonomously performs logical comparisons between available energy and required energy, and automatically adjusts operating parameters or displays error messages. This automation protects the system from damage while minimizing the complexity of the commissioning process for users.
3Ease of operation
If the drive system operates with full functionality, then the user experience is optimal, but energy consumption increases when energy availability is limited
Solution Approach 1:
The patent applies dynamics by making the drive system's functionality adaptive based on validated energy availability. The frequency converter continuously monitors the coordination between available energy and consumption requirements, dynamically adjusting operating parameters such as motor speed, power output, or operational mode. This ensures the system operates with optimal functionality when energy is abundant while reducing energy consumption when availability is limited, maintaining ease of operation across varying energy conditions.
