Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busbar junction boxes are not versatile and are custom-made, making them expensive and inflexible for adaptation to specific electrical installation configurations.
Innovation Solution
A busbar branch box with a modular design featuring a rectangular parallelepiped housing with crosspieces, cheeks, and separate openings that can be closed by a set of interchangeable faceplates, including solid, openwork, and door types, allowing for easy modification of the configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a junction box is custom-made with fixed dimensions and component positioning during manufacture, then it can be adapted to specific electrical installation constraints, but it becomes expensive and cannot be modified during implementation
Solution Approach 1:
The junction box is divided into modular components: a standardized housing and interchangeable faceplates. Each faceplate can be independently selected and installed based on the specific electrical installation requirements, allowing customization without custom manufacturing the entire box.
Solution Approach 2:
A single standardized housing design serves multiple configurations by accepting different faceplates. The same housing can be adapted to various installation constraints by simply changing the faceplate, making the system universal and multi-functional.
2Ease of manufacture
If the position of the door and circuit breaker is fixed in the housing, then the manufacturing process is simplified, but the junction box cannot be modified during implementation
Solution Approach 1:
The faceplate positions of doors and circuit breakers are made changeable rather than fixed. Users can install faceplates with different component positions according to implementation needs, providing dynamic adaptability while keeping the housing manufacturing simple and standardized.
3Adaptability or versatility
If a junction box configuration is not adapted to the electrical installation during implementation, then custom-made boxes avoid reconfiguration needs, but changes require expensive replacement of entire boxes
Solution Approach 1:
Instead of replacing the entire junction box when reconfiguration is needed, only the faceplate is replaced while the housing and other components are retained. This recovers most of the original investment and significantly reduces time and cost.
4Adaptability or versatility
If interchangeable faceplates are provided for different configurations, then the junction box becomes versatile and modifiable, but the device complexity increases
Solution Approach 1:
A single universal housing design works with multiple faceplate types, consolidating the system architecture. This reduces the overall complexity compared to having multiple specialized housing designs, as the housing remains standardized while faceplates provide the variability.

AI summary
A busbar junction box (30) comprises a housing (32) including at least two crossbars (34), a base, two side panels (36), and at least three separate openings extending perpendicularly from the side panels between two crossbars or between a crossbar and the base. The box includes an electrical distribution system (60) comprising an output electrical distribution device (66) and a disconnecting device (70). Each opening in the housing is closed by a faceplate (40), each faceplate being selected from a set of separate faceplates including a solid faceplate (42), a connecting faceplate, a perforated faceplate (44), and a faceplate with a door. Each faceplate allows all the openings in the housing to be closed. At least one faceplate is a perforated faceplate or a faceplate with a door, and the disconnecting device is located on one side of the housing comprising this faceplate, and at least one faceplate is a connecting faceplate that carries the electrical distribution device.
