Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power junction boxes with a square shape are difficult to install in slender spaces and occupy wiring chamber spaces, making adjustment of electrical parameters inconvenient due to the presence of adjustment modules within.
Innovation Solution
A long-strip power junction box design with wiring chambers at both ends of a power chamber, featuring a cover plate that covers the chambers and includes a circuit board and adjustment module, allowing for easy installation in narrow spaces and independent adjustment of electrical parameters without occupying wiring chamber space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the power junction box adopts a square shape, then it can provide sufficient internal space for components, but it becomes difficult to install in slender spaces
Solution Approach 1:
The power junction box is divided into multiple functional chambers (power chamber and wiring chambers) arranged linearly, transforming the compact square design into an extended long-strip configuration that fits slender installation spaces while maintaining adequate internal volume for components
Solution Approach 2:
The design transitions from a two-dimensional square footprint to a three-dimensional long-strip configuration, utilizing the length dimension to accommodate internal space requirements while reducing the width and height dimensions to fit slender installation environments
2Device complexity
If the adjustment module is installed at inner sides of wiring chambers, then it can be integrated within the power junction box, but it occupies wiring chamber space and makes parameter adjustment inconvenient
Solution Approach 1:
The adjustment module is extracted from the wiring chambers and relocated to the power chamber, eliminating the conflict between adjustment operations and cable installation while maintaining integration within the overall power junction box structure
Solution Approach 2:
The power chamber serves as an intermediary space that houses the adjustment module, allowing it to be integrated into the power junction box without interfering with the wiring chambers' primary function of cable routing and organization
3Volume of stationary object
If the adjustment module is located within wiring chambers, then it can be housed within the power junction box, but cables affect the adjustment of electrical parameters
Solution Approach 1:
The power junction box is segmented into distinct functional zones: the power chamber for housing the adjustment module and circuit board, and separate wiring chambers for cable management, preventing cable interference with adjustment operations
Solution Approach 2:
The adjustment module is taken out from the wiring chamber environment and relocated to the power chamber, eliminating the harmful interaction between cables and adjustment operations while maintaining compact integration
