Modular Tree Lighting Connectors for Fast Safe Segment Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tree-shaped lighting decorations require time-consuming electrical connections between segments, and existing solutions for regular voltage levels lack safety compliance and modular flexibility, with electrical components often being inseparable and not meeting safety regulations.
Innovation Solution
A modularized extension cable assembly with cylindrical socket and plug, along with an ancillary component, allows simultaneous mechanical and electrical connection of tree segments, enabling use as a standalone device and compliance with regular voltage levels, facilitating easy assembly and disassembly while ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical connection is made separately after assembling tree segments, then electrical connection can be established, but it consumes a lot of time and reduces assembly efficiency
Solution Approach 1:
The patent combines electrical connection components (male and female connectors) directly into the tree segment structures. When tree segments are mechanically assembled together, the electrical connectors automatically engage simultaneously, eliminating the need for separate electrical connection steps and reducing assembly time.
Solution Approach 2:
The electrical connection components are pre-installed and integrated into the tree segments during manufacturing. This preliminary integration ensures that when the segments are assembled by the consumer, the electrical connections are already in place and will automatically connect, saving time during assembly.
2Reliability
If low voltage is used for tree-shaped decoration, then operation safety is improved, but it requires a transformer and complicates the system
Solution Approach 1:
The patent changes the voltage parameter from low voltage to regular voltage level by designing electrical components that comply with regular voltage safety regulations. This eliminates the need for transformers while maintaining safety through proper component design and certification.
3Stability of the object's composition
If electrical connection components are integrated in an inseparable manner, then structural integrity is improved, but the components cannot be used independently and reduces flexibility
Solution Approach 1:
The patent segments the electrical connection system into modular tree segment units, each with integrated electrical components. These modular segments can be assembled in different configurations and the electrical components can be used independently with each segment, providing both structural integrity and usage flexibility.
4Productivity
If electrical connection components are integrated into tree segments, then simultaneous connection is achieved, but the components are not compliant with safety regulations for standalone use
Solution Approach 1:
The patent designs the electrical connection components to serve dual purposes: they are integrated into the tree segments for efficient assembly, but each component (male and female connectors) is also designed to function as a standalone electrical connection device that complies with safety regulations, allowing versatile use scenarios.

AI summary
A structure of tree-shaped lighting decoration includes an extension cable assembly, which is a modularized assembly adapted to carry a regular voltage supplied from an electric main and has an end forming a cylindrical socket and an opposite end forming a cylindrical plug, a tree-segment tube having an end section forming a retention tubular section that has a reduced portion for positioning and retaining the cylindrical socket, an ancillary component including a conical body that forms therein a stepped bore that has a side opening. The stepped bore of the ancillary component and the cylindrical plug are respectively provided with mated dimple and bump for engaging each other. The ancillary component receiving the cylindrical plug therein is fit into an opposite end of the tree-segment tube to form a tree segment. Alternatively, the extension cable assembly can be used as a stand-alone device.
