Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power breaking poles require adjustment and additional linking units for vacuum interrupters of different sizes, complicating assembly and increasing costs.
Innovation Solution
A modular power breaking pole design using two connectors to center and hold vacuum interrupters of varying lengths between two uprights, eliminating the need for additional linking units and allowing for interchangeable vacuum interrupters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a linking unit is used to rigidly interlink the two uprights, then the mechanical cohesion of the power breaking pole is provided, but the number of components increases and assembly is complicated
Solution Approach 1:
The patent merges the function of the linking unit with the connectors. The connectors are designed to perform both the electrical connection function and the mechanical linking function simultaneously. By integrating these two functions into a single component, the number of parts is reduced and assembly is simplified while maintaining the mechanical cohesion of the structure.
Solution Approach 2:
The connectors are designed as multi-functional elements that serve both electrical and mechanical purposes. Each connector provides electrical connection between the vacuum interrupter terminals and the uprights, while also rigidly interlinking the two uprights to provide mechanical cohesion. This multi-functionality eliminates the need for separate linking units.
2Adaptability or versatility
If the linking unit is adjusted to different dimensions, then vacuum interrupters of different sizes can be accommodated, but the device complexity and assembly difficulty increase
Solution Approach 1:
The connectors are designed with universal characteristics that allow them to accommodate vacuum interrupters of different dimensions. The holding means on the uprights are configured to work with the connectors in a standardized manner, while the connectors themselves can adapt to different vacuum interrupter sizes. This universality allows the same connector design to serve multiple applications without requiring adjustment or modification.
Solution Approach 2:
The patent incorporates adjustable elements in the connector assembly that allow for dynamic adaptation to different vacuum interrupter dimensions. The holding means and connectors are designed with degrees of freedom that enable them to accommodate variations in vacuum interrupter size while maintaining proper electrical and mechanical connections, eliminating the need for multiple specialized linking units.
3Reliability
If additional linking units are used, then the vacuum interrupter can be securely held, but the assembly time and cost increase
Solution Approach 1:
The patent combines the securing function with the electrical connection function in the same component. The connectors securely hold the vacuum interrupter in place while simultaneously providing electrical connection. This merging of functions reduces the number of assembly steps and components, thereby reducing assembly time and cost while maintaining reliable securing of the vacuum interrupter.
