Auxiliary Contact Configuration With Segmented Control Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary contact configurations for switching devices require different designs for the control device depending on how auxiliary contacts change positions, leading to inefficiencies in configuration flexibility.
Innovation Solution
An auxiliary contact configuration with two positions near each other, each controlled by a distinct control element within the auxiliary contact control device, allowing the installation location to determine the switching mechanism, enabling the same components to form different operating configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the auxiliary contact control device is designed differently for different configurations, then each auxiliary contact can change position as desired, but the device complexity increases and manufacturing efficiency decreases
Solution Approach 1:
The patent applies universality by designing a single auxiliary contact control device that can control multiple auxiliary contacts in different positions (first, second, and third positions) with different switching behaviors. The control device includes control elements that can be selectively activated depending on which auxiliary contact position is installed, allowing one device design to serve multiple configuration purposes without requiring separate control devices for each configuration type.
Solution Approach 2:
The patent applies segmentation by dividing the auxiliary contact control device into multiple independent control elements (first control element, second control element, third control element), each corresponding to a specific auxiliary contact position. This segmentation allows the control device to be selectively configured by activating only the relevant control elements based on the installed auxiliary contact position, thereby reducing the effective complexity while maintaining design flexibility.
2Adaptability or versatility
If multiple different control device designs are produced, then different auxiliary contact configurations can be achieved, but the manufacturing cost and inventory requirements increase
Solution Approach 1:
The patent reduces manufacturing complexity by producing a single universal auxiliary contact control device design that can accommodate multiple auxiliary contact configurations. The device includes multiple control elements that can be selectively activated based on the installed auxiliary contact position, eliminating the need to manufacture and inventory multiple different control device variants while still providing all required configuration options.
3Ease of manufacture
If the same components are used for different configurations, then manufacturing efficiency improves, but the ability to achieve different switching behaviors decreases
Solution Approach 1:
The patent enables component standardization while maintaining configuration flexibility by segmenting the control device into distinct control elements (first, second, third control elements), each associated with a specific auxiliary contact position. This segmentation allows the same standardized control device to achieve different switching behaviors by selectively activating different control elements based on which auxiliary contact position is installed, thus preserving adaptability while improving manufacturability.
