Solution Overview
Problem
Existing gas safety valves face limitations in electrical connection systems due to their compact design, requiring special connectors and reducing available space for the coil, which complicates the integration of standard connectors and increases costs.
Innovation Solution
The design integrates standard connectors within the support of the gas safety valve, allowing for reliable and cost-effective electrical connections using a conductive support with a reel and phase closure, enabling the use of standard connectors for both phase and ground wires, thus reducing the need for special connectors and optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrical connections are performed outside the support by welding phase wire and ground wire to terminal, then electrical connection is achieved, but available space is reduced and welding difficulty increases
Solution Approach 1:
The patent implements nesting by placing the phase closure inside the support housing, and further nesting the electrical contact areas within the phase closure structure. This nested arrangement allows electrical connections to be made inside the support without increasing external dimensions, thereby preserving coil space while facilitating easier electrical connection through the integrated internal structure.
Solution Approach 2:
The patent introduces a phase closure as an intermediary component between the support and the electrical terminals. This phase closure contains the electrical contact areas and mediates the electrical connection process, allowing wires to be connected to contact areas within the phase closure, which is itself housed within the support. This intermediary structure simplifies the manufacturing process by providing a dedicated space for electrical connections without requiring welding outside the support.
2Ease of manufacture
If electrical connections are performed in the area of core and coil, then electrical connection is achieved, but space for coil is reduced and distance between terminals cannot be reduced
Solution Approach 1:
The patent segments the electrical connection system into distinct components: the support, the phase closure, and the electrical contact areas. By separating the electrical connection function into the phase closure component housed within the support, the design avoids cluttering the core and coil area with connection elements. This segmentation allows the coil to maintain its required space while electrical connections are facilitated through the dedicated phase closure structure.
3Adaptability or versatility
If support performs multiple functions including tightness and electrical connection, then compact design is achieved, but available space for electrical connection is reduced
Solution Approach 1:
The patent resolves the space constraint by nesting the phase closure inside the support housing. This nested arrangement allows the support to maintain its multi-functional role (providing structural support, tightness, and housing for electrical components) while the phase closure provides dedicated space for electrical connections. The nested structure ensures that electrical connection space is created within the existing support volume without compromising the support's other functions.
