Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metal junction boxes for LED downlights are too large, making them inconvenient to transport.
Innovation Solution
A power supply device comprising a detachably connected junction box and power supply box, where the power supply box can fit inside the junction box during transportation, allowing for independent wiring and power areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply and lamp body are separated with the power supply placed inside a metal junction box for safety, then the protection of wires and power supply is improved, but the package and transportation space becomes too large
Solution Approach 1:
The patent divides the downlight system into separate modules: a junction box for wiring and a power supply box for the power adapter. This segmentation allows each component to be optimized independently - the junction box provides safety protection while the power supply box can be compactly designed, reducing overall transportation space when not in use.
Solution Approach 2:
The power supply box is designed to nest within the junction box when not in use. The junction box has a cavity that accommodates the power supply box, allowing both components to occupy the same space during storage and transportation, thereby significantly reducing the required package volume.
2Ease of operation
If the junction box and power supply box are detachably connected, then the installation speed and ease of operation are improved, but the device complexity increases due to additional connection components
Solution Approach 1:
The connection between the junction box and power supply box is designed to be dynamic rather than fixed. The detachable connection allows the power supply box to be easily attached or removed from the junction box, enabling quick installation and maintenance operations without requiring complex tools or procedures.
Solution Approach 2:
The electrical connection is designed so that when the power supply box is inserted into the junction box, the electrical contacts automatically align and connect at the same potential level, ensuring safe and reliable electrical connection without requiring complex wiring or adjustment procedures.
