Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial trees with pre-lit systems face challenges in assembly and power distribution due to the complexity and weight of multiple light strings, requiring cumbersome plug connections and rotational alignment of tree sections, which complicates the process of setting up and powering the trees.
Innovation Solution
A modular artificial tree design that allows for mechanical and electrical connection of tree portions along a common vertical axis without rotational orientation, using trunk connectors and wiring harnesses to simplify assembly and power distribution, with a power converter securely located within the base portion to manage power efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light strings are distributed throughout the tree to enhance decorative quality, then the decorative effect is improved, but the weight and complexity of the tree increases making it difficult to assemble and power
Solution Approach 1:
The tree is divided into multiple separable sections with integrated lighting systems. Each section contains its own light strings and wiring harnesses, allowing the lighting functionality to be segmented across modules rather than concentrated in one heavy unit. This enables easier handling and assembly while maintaining the overall decorative lighting effect.
2Illumination intensity
If multiple light strings with plug connections are used to provide power distribution, then the lighting coverage is improved, but the complexity of interconnecting and powering the light strings increases significantly
Solution Approach 1:
The electrical connectors are integrated directly into the mechanical coupling mechanism of the tree sections. When two tree sections are mechanically joined together, the electrical connectors automatically align and establish electrical contact, merging the mechanical assembly function with the electrical connection function into a single unified action.
Solution Approach 2:
The system automatically establishes electrical connections between light strings when tree sections are assembled together. The connectors are positioned such that the act of joining tree sections self-service the electrical wiring task, eliminating the need for users to manually connect plugs and receptacles.
3Stability of the object's composition
If tree sections require rotational alignment for connection, then precise mechanical coupling is achieved, but the assembly process becomes more difficult and time-consuming
Solution Approach 1:
The electrical connectors are designed with asymmetric positioning relative to the tree section geometry. This asymmetric configuration creates a self-aligning mechanism where the connectors naturally orient themselves during the assembly process, eliminating the need for precise rotational alignment while maintaining secure mechanical coupling.
4Power
If the power converter is located externally in the base, then power conversion functionality is provided, but the risk of dislodgment and instability increases
Solution Approach 1:
The power converter is nested within the base structure of the tree stand, integrating it into the existing framework rather than positioning it externally. This nesting approach provides structural support and stability while maintaining the power conversion functionality, eliminating the risk of dislodgment associated with external placement.

AI summary
A lighted artificial tree includes a first tree portion including a first trunk portion, first branches joined to the first trunk portion, and a first light string. The first trunk portion has a trunk connector and a first trunk wiring assembly, the first trunk wiring assembly is electrically connectable to the first light string and the trunk connector, and at least a portion of the first wiring assembly is located inside the first portion. The second tree portion includes a second trunk portion, second branches, and a second light string. The second trunk portion has a trunk connector and a second trunk wiring assembly, the second trunk wiring assembly electrically connectable to the second lighting string and the trunk connector. The second tree portion may be mechanically coupled and electrically connected to the first tree portion by coaxially coupling the first trunk portion to the second trunk portion.
