Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices face challenges in simple and cost-effective maintenance and commissioning, particularly in quickly reconfiguring fieldbus parameters and replacing defective modules without disrupting the fieldbus system.
Innovation Solution
The electrical device is designed with modular components, where each module has an electronic circuit on a heat sink, allowing for rapid replacement and commissioning by reading out and reusing original fieldbus parameters, and utilizing a memory element for storing and retrieving subscriber addresses and other parameters through a plug-in connection, enabling seamless integration into the system bus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If electrical devices are replaced including the lower part with electronic circuit, then maintenance and commissioning can be performed, but rapid commissioning is difficult because new fieldbus parameters must be configured manually
Solution Approach 1:
The memory element stores fieldbus parameters (subscriber address, baud rate, etc.) in advance before the electrical device is replaced. When the new electrical device is installed, these pre-stored parameters are automatically read out and activated, eliminating the need for manual reconfiguration and enabling rapid commissioning.
2Weight of stationary object
If electrical devices are made compact with heat sink, then mass is reduced making exchange easier, but heat dissipation requirements increase
Solution Approach 1:
The heat sink utilizes phase transition of heat transfer media (such as convection currents in air or liquid coolants) to efficiently dissipate heat from the compact electrical device. This allows the device to maintain small mass while effectively managing thermal load through phase change-based heat transfer mechanisms.
3Ease of repair
If modular design is implemented with upper and lower parts, then defective modules can be replaced rapidly, but device complexity increases
Solution Approach 1:
The electrical device is divided into modular components (upper part with memory element and lower part with electronic circuit). This segmentation allows defective modules to be independently replaced without affecting other components, enabling rapid maintenance while the standardized modular interface keeps the overall system manageable.
4Reliability
If memory element is designed as mechanical version (DIP switch), then memory is stable and robust, but data storage capacity is limited
Solution Approach 1:
The patent allows flexible selection between mechanical memory elements (DIP switches) for high reliability and electronic memory elements for increased data storage capacity. This parameter change enables the system to be optimized based on specific application requirements, balancing reliability and storage needs.
