Electricity Meter Housing Pin and Through-Opening Locking Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electricity meter housings lack efficient mechanisms for secure assembly and verification of proper closure, which can lead to unauthorized access and potential damage during installation.
Innovation Solution
A housing design featuring a lower housing part with a through-opening and an upper housing part with a pin that engages in the opening upon closure, ensuring secure locking and allowing for easy verification of proper engagement through force-displacement measurement, along with guiding means to facilitate precise assembly and labeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the housing is closed by simply snapping the lower and upper housing parts together, then the closing process is simple and quick, but the secure locking and verification of proper closure are insufficient
Solution Approach 1:
The patent implements feedback by providing verification means (through-openings with pins or protrusions) that allow visual or tactile confirmation of proper locking. When the housing parts are correctly assembled, the pins align with the through-openings, providing immediate feedback that the locking is secure. This resolves the contradiction by maintaining simple closing operation while adding reliable verification capability.
2Reliability
If multiple locking elements are used to improve secure locking, then the locking security is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into single elements. The locking elements serve both as securing mechanisms and as verification features. The same protrusions that engage in the through-openings for secure locking also serve as the verification means, allowing assembly status to be confirmed without additional components. This resolves the contradiction by enhancing locking security while avoiding increased complexity.
3Object-affected harmful factors
If the housing parts are designed to prevent opening without damage, then unauthorized access is prevented, but the ease of legitimate maintenance and repair is reduced
Solution Approach 1:
The patent implements self-service through the verification means that allow users to confirm proper locking without requiring disassembly or specialized tools. The through-openings with pins provide automatic visual or tactile indication of secure assembly, enabling end-users to verify installation correctness themselves. This resolves the contradiction by preventing unauthorized access while maintaining ease of legitimate maintenance through simple verification capability.

AI summary
Housing for an electricity meter with a lower housing part having a first locking element and an upper housing part having a second locking element, wherein the housing is designed to be closed by bringing the upper housing part and the lower housing part together along a closing direction, and wherein the first locking element and the second locking element are locked together when the housing is closed, characterized in that the lower housing part has a through-opening and the upper housing part has a pin which is arranged in the through-opening when the housing is closed.
