Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medium voltage switchgear designs require separate compartments for inner cone and outer cone bushings, limiting flexibility and efficiency in cable connections.
Innovation Solution
A connection apparatus with an outer cone cable connection and a cable connection block that accommodates both inner cone and outer cone bushings, allowing for standardized compartments with interchangeable components for different cable sizes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate compartments are designed for inner cone and outer cone bushings, then each cable connection type can be properly accommodated, but the number of different compartment designs increases and flexibility decreases
Solution Approach 1:
The patent applies universality by designing a single compartment that can accommodate both inner cone and outer cone bushing connections. The compartment includes a standardized outer cone cable connection and a cable connection block with inner cone connections, allowing one compartment design to serve multiple cable connection purposes, thereby reducing the need for separate compartment designs for each cable type.
Solution Approach 2:
The patent applies segmentation by separating the cable connection functionality into modular components: an outer cone cable connection integrated into the compartment and a detachable cable connection block containing inner cone connections. This modular approach allows the inner cone connections to be added or removed as needed, providing flexibility while maintaining a standardized base compartment design.
2Reliability
If bespoke compartments are created for each cable connection type, then optimal connection performance is achieved, but manufacturing costs and installation time increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring the compartment with standardized outer cone cable connections and providing a cable connection block with pre-arranged inner cone connections. This pre-prepared modular configuration allows for quick assembly and installation without requiring custom fabrication for each cable type, thereby improving installation efficiency while maintaining reliable connections.
Solution Approach 2:
The patent introduces a cable connection block as an intermediary component that bridges between the standardized outer cone cable connection in the compartment and the various inner cone cable connections. This intermediary module allows different cable types to be connected to a standardized interface, ensuring reliable connections while simplifying installation and reducing the need for bespoke compartment designs.
3Ease of manufacture
If a standardized compartment with outer cone connection is used, then manufacturing efficiency improves, but the ability to connect inner cone cables is lost
Solution Approach 1:
The patent applies dynamics by making the cable connection configuration adjustable rather than fixed. The compartment is manufactured with a standardized outer cone connection, and the inner cone connections are provided through a detachable cable connection block that can be added or removed based on the specific cable connection requirements. This dynamic configuration allows the same compartment design to adapt to different cable types while maintaining manufacturing efficiency.
