Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional surge protector is used, then surge protection function is provided, but the device size becomes excessively large and structure becomes complex
Solution Approach 1:
The patent combines the surge protector main body directly inside the flameproof enclosure, eliminating the need for separate external mounting structures. The surge protector main body is positioned to utilize the internal space of the flameproof enclosure efficiently, merging what were previously separate components into an integrated assembly.
Solution Approach 2:
The surge protector main body is nested within the flameproof enclosure, with the enclosure serving as the outer housing that contains and protects the surge protector components. This nesting arrangement eliminates the need for additional external mounting structures and reduces overall device complexity.
2Reliability
If a conventional surge protector is used, then surge protection function is provided, but the device cannot be installed inside explosion-proof lamps due to size constraints
Solution Approach 1:
The surge protector and flameproof enclosure are merged into a single integrated device, allowing the surge protector to be installed directly inside explosion-proof lamps without requiring separate external mounting space.
Solution Approach 2:
The surge protector main body is nested within the flameproof enclosure, utilizing the internal volume of the enclosure for surge protection components. This nesting approach minimizes the overall device volume while maintaining full surge protection functionality.
3Productivity
If the flameproof enclosure is made by extrusion process, then manufacturing efficiency is improved, but structural complexity increases
Solution Approach 1:
The flameproof enclosure is designed with a cylindrical shape, which is well-suited for extrusion manufacturing. The curved cylindrical form allows for efficient extrusion production while maintaining the structural integrity and flameproof properties required for explosion-proof applications.
