Power Junction Box Layout for Accessible Parameter Adjustment

Solution Overview

Problem

Existing power junction boxes with electrical parameter adjusting functions occupy wiring chamber space and have inconvenient user operation due to limited adjustment space.

Innovation Solution

The power box design includes adjusting modules on an inner cover plate within the power supply chamber, with adjusting holes on the inner cover plate, and a partition board separating the power supply chamber from wiring chambers, allowing for convenient adjustment without occupying wiring chamber space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adjusting modules are disposed inside wiring chambers, then electrical parameter adjustment function is achieved, but wiring chamber space is occupied and user operation becomes inconvenient

Engineering Contradiction:

Improveelectrical parameter adjustment functionVSAvoiduser operation convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The power box is segmented into distinct functional zones: the power supply chamber contains the adjusting modules on its inner cover plate, while the wiring chambers remain separate for cable connections. This spatial segmentation allows the adjusting modules to be positioned in the power supply chamber rather than inside the wiring chambers, preserving wiring space and improving user accessibility during parameter adjustment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adjusting modules are mounted on the inner cover plate of the power supply chamber, utilizing the vertical dimension and the cover plate surface area. This dimensional relocation moves the adjusting modules from the horizontal wiring chamber space to the power supply chamber's cover structure, creating adequate operation space while maintaining the adjustment function.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If adjusting modules are disposed inside wiring chambers, then electrical parameter adjustment function is achieved, but wiring chamber space is occupied

Engineering Contradiction:

Improveelectrical parameter adjustment functionVSAvoidwiring chamber space

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The power box is segmented into distinct functional zones: the power supply chamber contains the adjusting modules on its inner cover plate, while the wiring chambers remain separate for cable connections. This spatial segmentation allows the adjusting modules to be positioned in the power supply chamber rather than inside the wiring chambers, preserving wiring space and improving user accessibility during parameter adjustment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adjusting modules are extracted from the wiring chambers and relocated to the inner cover plate of the power supply chamber. This extraction removes the space-occupying elements from the wiring chambers, freeing up valuable space for cable management while maintaining the electrical parameter adjustment capability through the relocated modules.

Inventive Principle:

Principle #2Taking out (Extraction)
