Solution Overview

Problem

Conventional electricity meter connection devices lack the capability to reliably tap voltage for supplying additional devices, such as communication devices, without requiring significant structural modifications to the support plate and connection conductors.

Innovation Solution

A plug element is used to tap voltage by inserting into an opening in the support plate, with minimal structural changes needed, and includes features like grooves and locking mechanisms to secure the conductor, allowing for easy integration with existing meter setups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If voltage tapping devices are added to the connection device, then the capability to supply additional devices is improved, but the device complexity increases

Engineering Contradiction:
Improvevoltage tapping capabilityVSAvoidconnection device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The voltage tapping function is segmented from the main connection device through modular plug elements. These plug elements can be independently inserted into opening elements on the support plate, providing voltage tapping capability without integrating complex tapping mechanisms into the core connection device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support plate is designed with dual functionality: it serves as both the mounting base for the electricity meter and as a platform for voltage tapping through integrated opening elements. This multi-functional design allows the same structural component to support both meter installation and voltage extraction without requiring separate dedicated structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If significant structural modifications are made to the support plate and connection conductors, then reliable voltage tapping is achieved, but the ease of manufacture deteriorates

Engineering Contradiction:
Improvevoltage tapping reliabilityVSAvoidsupport plate modification
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The support plate is pre-designed with opening elements during manufacturing, which already contain the necessary conductive structures and contact points for voltage tapping. This preliminary preparation eliminates the need for field modifications or complex post-assembly work, as the tapping functionality is already integrated into the base structure before installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The plug elements are designed as simple, inexpensive components that can be easily manufactured and replaced if needed. Rather than creating complex permanent modifications to the support plate, the invention uses simple plug-in elements that provide reliable voltage tapping through basic conductive contacts and locking mechanisms.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Area of stationary object

If the plug element is inserted deeply into the support plate, then the electricity meter placement is not hindered, but the ease of operation deteriorates

Engineering Contradiction:
Improvemeter placement areaVSAvoidplug element insertion
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The plug element incorporates an insulating portion that extends laterally to fill the opening in the support plate, creating a flush surface. This dimensional approach allows the conductive portion to insert deeply for reliable electrical contact while the insulating portion maintains the surface level, preventing interference with meter placement and providing a safe, tool-free installation process.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The device has a supporting plate (1) including an opening (2) for passage of terminal leads that are protruded from an electric meter. A tapping device taps a voltage for supplying of additional devices operated by the connecting device. The tapping device comprises a connector element (6) contacting one of the terminal leads and inserted into the opening in the supporting plate. An engagement device engages a lead (11) in a groove channel. An insulating part is completely provided in cross-section of the opening parallel to the supporting plate.
