Solution Overview

Problem

Conventional electrical meter enclosures require multiple parts and complex assembly processes, leading to difficulties in sealing and grounding, increased labor, and susceptibility to tampering, especially when handling phase conductors and neutral conductors.

Innovation Solution

A meter socket block with reversible orientation, integrated cap tracks, and a neutral buss assembly that captures lug caps, allowing for simplified installation and reduced parts, with phase conductor channels positioned centrally for enhanced security and reduced bending requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional meter enclosures use separate risers for ring style and ring less style sealing, then different sealing methods are supported, but device complexity and inventory requirements increase

Engineering Contradiction:

Improvesealing method compatibilityVSAvoidnumber of riser sizes

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The meter socket block is designed with a universal mounting structure that can accommodate both ring style and ring less style sealing methods using the same enclosure and riser configuration. The block includes integrated grounding means and sealing provisions that work with either sealing type, eliminating the need for different riser sizes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention reverses the conventional approach by integrating the sealing and grounding provisions directly into the meter socket block itself, rather than requiring separate riser components. The block includes built-in grounding lugs and sealing surfaces that eliminate the need for external risers, thereby simplifying the overall structure.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of manufacture

If phase conductors are connected at 45 degree angles with separated mounting blocks, then conductor connections are achieved, but installation difficulty increases due to bending requirements

Engineering Contradiction:

Improveconductor connection capabilityVSAvoidinstallation difficulty

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The invention merges the previously separated mounting blocks into a single integrated meter socket block. This consolidation aligns the phase conductor connections and neutral conductor connections in a straight line, eliminating the need to bend stiff insulated phase conductors during installation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention changes the spatial arrangement of conductor connections from a 45-degree angular configuration to a linear collinear configuration. This dimensional reorganization allows all conductors to be connected in a straight line, greatly simplifying the installation process.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If removable connector caps are used on meter mounting assemblies, then conductor insertion is enabled, but loss and misplacement of caps occurs

Engineering Contradiction:

Improveconductor insertion capabilityVSAvoidcap retention

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The connector caps are designed to be nested within recesses or cavities in the meter socket block when not in use. This nesting arrangement prevents caps from being lost or misplaced, while still allowing easy access for conductor insertion when needed.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The meter socket block includes integrated cap storage recesses that automatically retain the connector caps. The caps self-organize within the block structure, eliminating the need for separate storage containers or risk of loss.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If multiple separate parts are used for meter mounting assembly, then assembly flexibility is maintained, but assembly time and labor increase

Engineering Contradiction:

Improveassembly configuration flexibilityVSAvoidassembly time

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The invention combines multiple separate mounting components (mounting blocks, brackets, fasteners, grounding lugs) into a single integrated meter socket block. This consolidation maintains all necessary functional capabilities while dramatically reducing the number of assembly steps and components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated meter socket block performs multiple functions simultaneously: it provides mechanical mounting support, electrical grounding, conductor routing, and sealing provisions. This multi-functionality eliminates the need for separate components for each function, reducing assembly complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A watt-hour revenue socket block comprises at least three rising legs to allow the meter socket to step up or recess down depending on the orientation of the meter socket block. A cooperating meter socket enclosure has raised and lowered sections on the back wall to receive the rising legs to allow stepping up or recessing down of the meter socket. The meter socket has integral cap tracks to allow the cap to be moved to a position over the center of the meter socket block and be retained in that position by a tab while inserting the conductor in the lay in channel.
