Modular Switching Device Interconnected Shaft Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing modular switching devices require multiple types of main shafts with varying axial lengths and thicknesses due to differing power requirements for opening and closing poles, leading to complex manufacturing and storage needs.
Innovation Solution
The switching device employs interconnected main shaft elements within each module, eliminating the need for separate connecting elements by using male and female connecting members with universal teeth, allowing modules to connect directly and transfer torque without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connecting elements are used to connect main shafts between modules, then the connection strength and reliability are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the connecting element functionality into the main shaft itself by integrating male and female connecting members directly onto the shaft. This eliminates separate connecting components while maintaining reliable torque transfer between modules, resolving the contradiction between connection strength and device complexity
Solution Approach 2:
The main shaft is designed with universal male and female connecting members that can connect to various module types. This multi-functional design allows a single shaft design to serve multiple connection purposes across different switching device assemblies, reducing the need for multiple shaft variants while ensuring reliable connections
2Adaptability or versatility
If multiple types of main shafts are manufactured for different switching device assemblies, then the adaptability to different power requirements is improved, but the manufacturing complexity and storage requirements increase
Solution Approach 1:
The patent implements a universal main shaft design with standardized male and female connecting members that can accommodate different module configurations and power requirements. This single shaft design replaces multiple specialized shaft types, improving ease of manufacture while maintaining adaptability through modular assembly arrangements
Solution Approach 2:
The switching device is segmented into modular units with standardized connection interfaces. This segmentation allows different numbers and types of modules to be assembled using the same main shaft design, achieving adaptability to different power requirements without manufacturing multiple shaft variants
3Ease of operation
If modules are connected with separate connecting elements, then the ease of assembly and disassembly is improved, but the device complexity and bill of materials increase
Solution Approach 1:
The connecting functionality is merged into the main shaft structure itself through integrated male and female connecting members. This reduces the total number of parts while maintaining ease of assembly, as modules connect directly to the shaft without requiring separate connecting elements to be handled during assembly operations
