Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric meter designs require complex and time-consuming manual installation processes, increasing costs due to the need for precise alignment and connection of various components, which complicates the assembly and deployment of residential electric power measurement systems.
Innovation Solution
The electric meter features a combination of snap hooks and housing guides that allow for blind assembly of the electronics housing to the meter base, enabling secure and efficient alignment and connection of components without manual intervention, using guides and connectors to position option boards and current transformers in a perpendicular orientation for secure positioning and electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual assembly methods are used to couple the electronics housing to the meter base, then precise alignment and connection of components can be achieved, but the installation time and complexity substantially increase
Solution Approach 1:
The housing guides and option board guides are designed to automatically align and position the electronics housing and option boards during assembly. The guides self-align the components through their geometric constraints, eliminating the need for manual alignment operations while ensuring precise positioning of all electrical connections and mechanical interfaces.
Solution Approach 2:
The housing guides and option board guides serve as intermediary elements between the electronics housing and the meter base. These guides mediate the assembly process by providing predetermined alignment paths and positioning features, allowing components to be coupled with high precision without requiring manual intervention for alignment.
2Reliability
If manual assembly methods are used to connect various electric meter components, then precise connection can be achieved, but the complexity of the installation process substantially increases
Solution Approach 1:
The guide structure enables the assembly process to be self-servicing, where the geometry of the housing guides and option board guides automatically ensures correct positioning and connection of all components. This eliminates complex manual alignment procedures and reduces the skill level required for installation while maintaining high connection reliability.
Solution Approach 2:
The assembly system is segmented into discrete guided interfaces: housing guides for the main electronics housing and option board guides for peripheral boards. This segmentation allows each guide to be optimized for its specific alignment function, simplifying the overall assembly process while ensuring reliable connections at each interface point.
3Productivity
If guide structures are implemented to enable blind assembly, then installation time is reduced, but the device complexity increases due to additional guides and connectors
Solution Approach 1:
The housing guides and option board guides are designed as multi-functional elements that simultaneously provide alignment, positioning, and mechanical retention functions. Each guide structure serves multiple purposes in the assembly process, reducing the total number of separate components needed while enabling rapid blind assembly of all electric meter components.

AI summary
An electric meter comprises an electronics housing and a meter base. The electronics housing defines a front panel and includes a first plurality of option board guides. A main meter board is disposed substantially parallel to the front panel. The meter base defines a rear panel of the electric meter. The meter base includes a plurality of housing guides for receiving the electronics housing and a second plurality of option board guides disposed substantially perpendicularly to the rear panel. The second plurality of option board guides are adapted to receive an option board and to position the option board substantially perpendicularly to the main meter board of the electronics housing during assembly of the electronics housing to the meter base. The housing guides in combination with the first and second pluralities of option board guides enable blind assembly of the electronics housing to the meter base.
