Engineering Contradiction Analysis
1Reliability
If the number of plate resistor pieces is increased to achieve larger resistance magnitude, then the resistance capability is improved, but the size of the current-limiting resistor increases
Solution Approach 1:
The current-limiting resistor is divided into multiple independent current-limiting resistor unit modules, each containing a specific number of plate resistor pieces. This segmentation allows the system to achieve larger resistance magnitudes by combining multiple standardized modules rather than increasing the size of a single resistor, thereby maintaining manageable dimensions while achieving the required resistance capability.
Solution Approach 2:
The patent transitions from a single vertical stacking arrangement to a multi-dimensional configuration where multiple unit modules are arranged both vertically and horizontally. This dimensional expansion allows the system to achieve higher resistance magnitudes through spatial distribution rather than simply increasing the height or size of individual resistors.
2Reliability
If the size of the current-limiting resistor is increased to achieve larger resistance magnitude, then the resistance capability is improved, but the ease of movement and handling deteriorates
Solution Approach 1:
By segmenting the current-limiting resistor into multiple standardized unit modules, each module maintains a manageable size that is easy to handle and move. The required resistance capability is achieved by assembling multiple these smaller, easier-to-handle modules rather than using a single large resistor, thus improving ease of operation while maintaining resistance performance.
Solution Approach 2:
The patent distributes the resistance function across multiple dimensions by arranging unit modules in both vertical and horizontal configurations. This dimensional distribution allows the system to achieve high resistance magnitudes without concentrating mass in a single large component, thereby maintaining ease of movement and handling.
3Device complexity
If the current-limiting resistor is mounted directly on the switchboard without a separate supporting structure, then the device complexity is reduced, but the reliability and protection against external environmental factors deteriorates
Solution Approach 1:
The support system is segmented into modular components including a tower-shaped support structure with vertical columns, horizontal support beams, and insulating member brackets. This segmented support structure provides reliable protection and stabilization for each current-limiting resistor unit module while maintaining reasonable device complexity through modular assembly.
Solution Approach 2:
The patent introduces a tower-shaped support structure as an intermediary between the switchboard and the current-limiting resistor unit modules. This intermediary structure provides mechanical support, electrical insulation, and environmental protection, thereby improving reliability without requiring direct mounting of the resistors on the switchboard.
4Device complexity
If the current-limiting resistor lacks a separate supporting structure, then the device complexity is reduced, but the risk of damage during installation and movement increases
Solution Approach 1:
The current-limiting resistor system is segmented into transportable unit modules that can be handled and installed separately. Each module is designed with standardized dimensions and mounting interfaces, reducing the risk of damage during installation while maintaining acceptable device complexity through modular construction.
Solution Approach 2:
The patent employs a three-dimensional tower-shaped support structure with vertical columns and horizontal beams that provides comprehensive mechanical protection. This spatial configuration distributes mechanical loads and provides multiple attachment points, thereby enhancing strength and protection during installation and movement without excessive complexity.
5Volume of stationary object
If the current-limiting resistor unit modules are stacked vertically, then the space utilization is improved, but the cooling performance deteriorates
Solution Approach 1:
The patent combines vertical and horizontal arrangements of current-limiting resistor unit modules within the tower-shaped support structure. This multi-dimensional configuration optimizes space utilization by utilizing both vertical height and horizontal footprint, while maintaining adequate spacing and airflow paths for effective cooling performance.
