Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical box assemblies lack an effective mechanism to segregate high voltage and low voltage areas, leading to safety and organizational challenges when multiple types of transmission lines are housed together.
Innovation Solution
An adjustable voltage divider system within the electrical box assembly, featuring a voltage divider plate with scored lines that can be broken to adjust the height and position, creating distinct high and low voltage areas, is integrated into the housing, allowing for customizable separation of voltage zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed voltage divider plate is used to separate high voltage and low voltage areas, then voltage segregation is achieved, but the electrical box assembly lacks flexibility in configuring different voltage zones
Solution Approach 1:
The voltage divider plate is segmented into multiple removable sections along pre-scored break lines. This allows the plate to be divided into different configurations to create various voltage zone arrangements, providing flexibility without requiring a completely different structure for each configuration
Solution Approach 2:
The voltage divider plate transitions from a static, fixed structure to a dynamic, adjustable structure. The pre-scored break lines enable the plate to be reconfigured by breaking it along different lines, allowing the electrical box assembly to adapt to different voltage segregation needs
2Area of stationary object
If multiple transmission lines are housed together in a single electrical box, then space utilization is improved, but safety risks increase due to lack of voltage segregation
Solution Approach 1:
The voltage divider plate segments the internal space of the electrical box into distinct high voltage and low voltage areas. This physical segmentation allows multiple transmission lines to be housed together while maintaining proper voltage segregation, thus improving space utilization without compromising safety
Solution Approach 2:
The voltage divider plate acts as an intermediary barrier between high voltage and low voltage areas. It provides electrical isolation and physical separation, enabling safe co-housing of different voltage transmission lines within the same electrical box
3Manufacturing precision
If a custom-fitted voltage divider plate is manufactured for each electrical box configuration, then precise voltage segregation is achieved, but manufacturing cost and time increase
Solution Approach 1:
The break lines are pre-scored into the voltage divider plate during manufacturing, creating predetermined breaking paths. This preliminary action allows the plate to be easily reconfigured by end-users without requiring complex manufacturing processes, achieving both precision and ease of manufacture
Solution Approach 2:
A single voltage divider plate design with pre-scored break lines can serve multiple configuration needs. By breaking the plate along different pre-scored lines, the same plate can create various voltage zone arrangements, eliminating the need for custom-manufactured plates for each configuration

AI summary
An electrical box comprising an adjustable voltage divider may include a housing comprising an inner surface and ribs or threads integrally formed on the inner surface of the rectangular housing. A voltage divider plate may be disposed within the housing with vertical edges of the voltage divider plate extending along and held in place between the ribs or threads integrally formed on the inner surface of the housing, the voltage divider plate dividing the housing into a high voltage area and a low voltage area. The voltage divider plate area may comprise a plurality of horizontal guide lines vertically offset from each other, and a plurality of vertical guide lines horizontally offset from each other and intersecting the plurality of horizontal score lines. Upper outer corners of the voltage divider plate may be inwardly disposed from the vertical edges of the voltage divider plate.
