Two-Color Meter Cover Shiplap Joint Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional watt-hour meter covers are costly and difficult to manufacture, as they require additional shielding components and assembly processes to manage thermal budgets effectively due to high-powered electronics and solar radiation, which leads to increased internal heating.
Innovation Solution
A two-color molding method is used to create a meter cover with an opaque and transparent portion, featuring a shiplap joint bond and integrated solar shields, which reduces internal heating and provides robust impact resistance without additional shielding components or assembly processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional shielding components and assembly processes are used to manage thermal budgets, then thermal management is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent combines multiple functions (shielding, transparency, structural support) into a single integrated meter cover component. The cover includes both opaque and transparent portions with integrated shielding features, eliminating the need for separate shielding components and reducing assembly steps while maintaining thermal management effectiveness
Solution Approach 2:
The meter cover uses composite construction with both opaque and transparent portions in a single molded component. This allows different regions of the cover to have different optical properties while maintaining structural integrity and thermal management capabilities, resolving the contradiction between thermal control and manufacturing simplicity
2Temperature
If traditional shielding components are used to block solar radiation, then thermal budget is improved, but manufacturing cost increases
Solution Approach 1:
The shielding function is merged into the main cover body through the two-color molding process. The opaque portions provide solar radiation shielding while the transparent portions allow visibility, all in a single integrated component that reduces part count and manufacturing cost compared to traditional separate shielding components
Solution Approach 2:
The cover applies different material properties to different regions: opaque portions for shielding against solar radiation, and transparent portions for visibility. This localized differentiation achieves effective thermal management while maintaining manufacturing efficiency through a single molding process

AI summary
A meter cover is provided and includes an opaque portion, including an outer perimeter section to perimetrically fit around a meter, a sidewall extending axially from the perimeter section toward a frontal region and a shield disposed at a portion of a sidewall edge at the frontal region and a transparent portion having an edge, which is shiplap joint bonded with a remaining portion of the sidewall edge and edges of the shield.
