Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a typical enclosure structure is used for voltage transformer, then the structural strength and explosion prevention requirements are met, but the installation space occupied is very large and the machining cost is high
Solution Approach 1:
The enclosure shell is divided into multiple packaging spaces with closed ends and sealed ends, allowing modular arrangement of voltage transformer bodies. This segmentation enables compact positioning of components while maintaining overall structural integrity and explosion prevention capabilities through the reinforced rib design in each segment.
Solution Approach 2:
Multiple packaging spaces are arranged in a nested or adjacent configuration within the enclosure shell, with every two adjacent packaging spaces in communication. This nesting approach allows multiple voltage transformer bodies to be accommodated in a compact arrangement, reducing the total installation space while maintaining individual space requirements for each component.
2Strength
If a typical enclosure structure is used for voltage transformer, then the structural strength and explosion prevention requirements are met, but the machining cost for the entire shell is high
Solution Approach 1:
The shell is segmented into multiple packaging spaces with standardized closed ends and sealed ends, reducing machining complexity compared to a monolithic structure. Each segment can be manufactured independently with reinforced ribs for strength, lowering overall machining costs while maintaining explosion prevention requirements.
Solution Approach 2:
Reinforced ribs are strategically positioned at specific locations (closed ends and sealed ends of packaging spaces) where structural strength is most needed for explosion prevention. This localized reinforcement approach reduces material usage and machining complexity compared to uniformly thick-walled enclosures, lowering manufacturing costs while maintaining safety requirements.
3Volume of stationary object
If packaging spaces are arranged in adjacent configuration with communication between them, then the size along arrangement direction is reduced, but the structural complexity increases
Solution Approach 1:
The enclosure is divided into standardized packaging spaces with uniform closed ends and sealed ends, creating a modular structure that reduces overall size when arranged adjacently. The segmentation into repeating units simplifies design and manufacturing despite the complex spatial arrangement, as each module follows the same structural pattern.
Solution Approach 2:
Adjacent packaging spaces are merged into a single enclosure shell with internal communication pathways, eliminating the need for separate enclosures for each voltage transformer body. This merging reduces the total external dimensions while the internal segmentation maintains organizational structure, balancing compactness with manageable complexity.
