Universal Insulation Barrier Knockouts for Switchgear Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical insulation barriers for electronic apparatuses require multiple variations to accommodate different configurations of power connectors and horizontal branch buses, leading to inefficiencies in fabrication and logistics, as they need to be customized for various scenarios, which is time-consuming and resource-intensive.
Innovation Solution
A master or universal electrical insulation barrier with pre-defined knockout features made from brittle materials like thermoset insulating materials or glass reinforced polyester laminate, allowing for easy removal of specific shapes to create openings for intersecting parts, reducing the need for multiple single-use barriers and enabling customization on the assembly line or in the field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple variations of vertical wall insulation barriers are created to satisfy different scenarios of power connector and breaker locations, then the adaptability to different configurations is improved, but the device complexity and manufacturing complexity increase
Solution Approach 1:
The patent applies universality by designing a single master vertical wall insulation barrier that can serve multiple configurations through knockout features. Instead of creating multiple specialized barriers for different power connector and breaker locations, one universal barrier with pre-defined knockout patterns can be used across all scenarios, reducing the number of part variations while maintaining adaptability.
Solution Approach 2:
The patent applies segmentation by dividing the insulation barrier into functional regions with pre-defined knockout features at various locations. These knockout features are segmented into different patterns that can be selectively removed based on the specific configuration needed, allowing a single barrier design to accommodate multiple installation scenarios.
2Adaptability or versatility
If multiple variations of insulation barriers are manufactured for different scenarios, then the adaptability is improved, but the manufacturing time and logistics complexity increase
Solution Approach 1:
The patent eliminates the need to manufacture multiple specialized barrier variations by creating one universal barrier design that can be used for all power connector and breaker configurations. This single master part approach streamlines manufacturing operations, reduces production time, and simplifies logistics while maintaining the ability to accommodate different installation scenarios through selective knockout removal.
Solution Approach 2:
The patent applies preliminary action by pre-defining knockout features during the barrier manufacturing process. These knockout patterns are prepared in advance at various locations on the master barrier, allowing for quick customization in the field or assembly area without requiring additional manufacturing steps or tooling changes for different configurations.
3Ease of operation
If knockout features are added to the master part for customization, then the ease of operation and adaptability are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies segmentation by creating discrete, pre-defined knockout features at specific locations on the master barrier. Each knockout feature is segmented as a separate removable element with standardized dimensions and positioning, allowing for precise manufacturing using standard tooling while enabling easy field customization. The segmented design allows knockouts to be removed independently without affecting the integrity of the remaining barrier structure.

AI summary
A master electrical insulation barrier panel for use in a switchgear arrangement. The master electrical insulation barrier panel includes a plurality of optionally removable knock-out features, wherein each of the knock-out features has a peripheral edge. The peripheral edge includes a plurality of snapable tabs, wherein each snapable tab is separated by an opening configured to create a breakable weak link in a non-electrically conductive brittle material used for fabricating the master electrical insulation barrier wherein a weak link is associated with each of the optionally removable knock-out features. In addition, each of the optionally removable knock-out features corresponds to an optional opening for at least one possible electrical connection, such that at least one knock-out feature can be optionally removed from the master electrical insulation barrier panel during installation of the master electrical insulation barrier panel to create the optional opening for at least one electrical connection.
