Solution Overview

Problem

Current meter sockets with bypass mechanisms require the front cover to be removed to enable the bypass, exposing electricians to the risk of electrical shock when accessing the bypass mechanism during meter removal or replacement.

Innovation Solution

A meter socket design with a bypass conductor member and activator that can be activated through a closed meter box, allowing the bypass to be enabled without opening the front cover, using a sealed bypass activator cover plate and a keyed recess to translate rotational torque into linear motion for the bypass conductor member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the front cover is removed to enable bypass, then the bypass mechanism can be accessed, but electricians are exposed to electrical shock hazards

Engineering Contradiction:

Improvebypass activation accessibilityVSAvoidelectrical shock risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A bypass activator cover plate is introduced as an intermediary component that provides a safe interface between the user and the bypass mechanism. The cover plate can be opened to activate the bypass while maintaining safety, eliminating the need to remove the entire front cover and exposing live electrical components.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The front cover is segmented into a main cover and a separate bypass activator cover plate. This segmentation allows the bypass function to be accessed independently through the smaller cover plate without removing the main cover, thereby maintaining protection against electrical shock while enabling bypass operation.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the bypass is activated through a closed meter box, then electrical safety is improved, but the device complexity increases

Engineering Contradiction:

Improveelectrical safetyVSAvoidbypass activation mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bypass activator cover plate is nested within the meter box structure, and the bypass mechanism components are nested within the cover plate assembly. This nested arrangement allows the complex bypass functionality to be integrated into the existing meter box structure without requiring separate external mechanisms.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The bypass activator cover plate combines multiple functions: it serves as a protective cover, an activation interface, and a structural component of the bypass mechanism. By merging these functions into a single integrated component, the overall device complexity is reduced despite adding safety features.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A meter socket for a meter box includes a set of meter jaws to receive a watt-hour meter, a bypass conductor member to selectively connect the meter jaws and provide a bypass for the watt-hour meter, and an activator for the bypass conductor member. The activator is configured to be activated by a user through a closed meter box to move the bypass conductor member from a metered position to a bypass position.
