Hook-on Basepan Assembly for Metering Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of meter devices and basepan assemblies in modular metering systems is complex, time-consuming, and requires careful attachment for safety, particularly in ensuring electrical seals between sections.
Innovation Solution
A composite basepan with a hangable or 'hook-on' basepan support that allows for easy, quick, and secure attachment within a meter enclosure, minimizing the number of openings needed for electrical sealing, using interlocking components like load stabs, hold-down inserts, and positioning pillars for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional basepan installation methods are used, then secure attachment is achieved, but installation complexity and time increase
Solution Approach 1:
The basepan assembly is divided into separate modular components including the basepan body, basepan support with insert latches, hold-down insert, and positioning pillars. Each component can be independently manufactured and assembled, simplifying the overall installation process while maintaining secure attachment through the interlocking mechanism of these segmented parts
Solution Approach 2:
The basepan support is extracted as a separate hangable component with pre-attached insert latches, allowing it to be independently positioned and secured to the barrier before the basepan body is installed. This separation enables simpler, more flexible installation procedures
2Reliability
If traditional basepan installation methods are used, then secure attachment is achieved, but installation time increases
Solution Approach 1:
The insert latches are pre-attached to the basepan support during manufacturing, and the positioning pillars are pre-positioned on the basepan body. This preliminary preparation eliminates the need for on-site assembly of these critical securing elements, significantly reducing installation time while ensuring reliable attachment when the components are hung on the barrier
Solution Approach 2:
The modular segmented design allows installers to work with smaller, more manageable components that can be quickly positioned and secured, reducing the overall time required for basepan installation compared to installing a single large integrated unit
3Reliability
If multiple openings are made in the barrier for basepan installation, then secure attachment is achieved, but electrical sealing requirements increase
Solution Approach 1:
The basepan support with its insert latches is merged into a single hangable unit that can be secured to the barrier through minimal openings. The hold-down insert is then merged with the basepan body, creating an integrated assembly that reduces the number of separate attachment points and corresponding electrical sealing requirements
4Reliability
If complex installation procedures are used, then proper electrical seals are maintained, but installation ease decreases
Solution Approach 1:
The modular basepan assembly with its pre-configured interlocking components is designed to be self-explanatory and self-assembling to a程度, reducing the need for complex installation procedures. The natural fit and locking mechanisms guide the installer through the process while maintaining electrical seal integrity through the minimized and strategically positioned openings

AI summary
A basepan assembly for hook-on attachment onto a metering device is provided including a basepan support having at least two insert latches disposed at a first end and a side flange disposed at a second opposite end. A basepan body is provided being insertable onto said basepan support and including an inside wall configured to be attachable to a barrier of the metering device, as well as an outside wall, a bus stab chamber, and a hold-down insert configured to be attachable to the basepan body, the hold-down insert further having a side barrier. A top load stab having a first end affixable to the hold-down insert is provided and a bottom load stab insertable within said bus stab chamber is provided.
