Modular Barn Lantern Lamp with Replaceable LED Bulb
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional decorative barn lantern string lamps are non-replaceable, leading to high usage costs and limited service life, as the entire string must be discarded if one lamp is damaged.
Innovation Solution
Design of an outdoor decorative lamp with a modular structure comprising a lamp holder, lampshade, and detachable decorative shell, featuring a lampwick component with replaceable LED luminescent parts and a split-type shell design that allows for easy assembly and disassembly, reducing costs and extending the lamp's service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If lamps are directly integrally molded outside the power cable to form barn lantern lamps, then the connection between lamps and power cable is achieved, but the lamps cannot be replaced and the entire string must be scrapped if one lamp is damaged
Solution Approach 1:
The barn lantern lamp is divided into separate components: the power cable with lamp sockets, the individual lamp units with bulb holders, and the decorative shell. This segmentation allows the lamp units to be independently replaced while keeping the power cable and shell intact, resolving the contradiction between ease of manufacture and ease of repair.
2Reliability
If the entire string is scrapped when one lamp is damaged, then the connection integrity is maintained, but the usage cost increases significantly
Solution Approach 1:
The design allows damaged lamp units to be discarded and replaced while recovering and reusing the power cable, lamp sockets, and decorative shell. This principle reduces material loss and usage costs by maintaining the functional integrity of the non-damaged components while replacing only the faulty lamp units.
3Shape
If the decorative shell is made as a single integrated piece, then the appearance is complete, but assembly and disassembly become difficult
Solution Approach 1:
The decorative shell is segmented into multiple parts that can be easily assembled and disassembled. The shell includes a main body portion and a bottom portion that can be separated, allowing easy access to the lamp units for replacement while maintaining the complete appearance when assembled.
4Ease of repair
If the lamp structure is made modular with detachable components, then individual lamp replacement becomes possible, but the device complexity increases
Solution Approach 1:
The modular components are designed with universal features: standardized lamp sockets that fit multiple lamp types, a decorative shell that can accommodate different lamp configurations, and a power cable with universal connectors. This universality reduces the practical complexity by allowing the same components to serve multiple functions and configurations.

AI summary
The present disclosure relates to the technical field of lamps, and discloses an outdoor decorative lamp, including a lamp holder and a lampshade connected to the lamp holder, and further including a lampwick component and a decorative shell, an annular connecting port is arranged at a top of the accommodating cavity; and the lamp holder extends out of the accommodating cavity through the annular connecting port. In the present invention, a traditional integrated barn lantern lamp is transformed into a replaceable barn lantern lamp bulb by assembling and combining a lamp bulb with the decorative shell. Lamps on a barn lantern string can be replaced at any time, which significantly reduces the usage cost.
