Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional artificial tree branches and string lights are separately disposed, leading to exposed leads that lack aesthetic appeal, are prone to being pulled by children, and may leak current, failing to emit light effectively as a decoration.

Innovation Solution

An artificial tree branch with integrated string lights, where a spirally wrapped wire with decorated blades is combined with a main stem, and LED patches are electrically connected to a lead, which is interlaced with the wrapped wire, enhancing aesthetic appeal and strength while shielding the leads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If string lights are separately disposed from the artificial tree branch, then the artificial tree branch can be decorated, but the exposed leads have poor protection and may leak current

Engineering Contradiction:

Improveprotection of string lights leadsVSAvoidexposed leads causing safety hazards

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines the artificial tree branch and string lights into a single integrated product. The lead is embedded within the artificial tree branch structure, merging two previously separate components (decoration and lighting) into one unified object that eliminates exposed leads while maintaining both aesthetic and lighting functions

Inventive Principle:

Principle #5Merging (Combining)

2Shape

If string lights are separately disposed from the artificial tree branch, then the artificial tree branch can be decorated, but the exposed leads have no aesthetical appeal

Engineering Contradiction:

Improveaesthetic appeal of decorationVSAvoidexposed leads reducing aesthetic quality

Core Design Contradiction:

ShapeVSObject-affected harmful factors

Solution Approach 1:

By integrating the string lights into the artificial tree branch structure, the design eliminates the visual disruption of exposed leads. The lighting component becomes part of the decorative element itself, creating a unified aesthetic appearance where the lead is concealed within the branch structure

Inventive Principle:

Principle #5Merging (Combining)

3Illumination intensity

If string lights are separately disposed from the artificial tree branch, then the artificial tree branch can be decorated, but the artificial tree branch or decoration fails to emit light

Engineering Contradiction:

Improvelight emission capabilityVSAvoidseparate disposal of string lights

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The patent merges the lighting function directly into the artificial tree branch by embedding the LED lights and lead within the branch structure. This integration allows the decoration to emit light as an inherent feature rather than requiring separate string light disposal, simplifying the overall system while adding lighting capability

Inventive Principle:

Principle #5Merging (Combining)

4Ease of operation

If the lead is exposed, then the string lights can be installed, but the lead is prone to pulling by children

Engineering Contradiction:

Improveinstallation of string lightsVSAvoidsafety against pulling and current leakage

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The lead is embedded within the artificial tree branch structure, merging the electrical connection pathway with the physical structure of the decoration. This integration eliminates the exposed portion that children could pull, while maintaining electrical connectivity through the embedded lead pathway within the branch material

Inventive Principle:

Principle #5Merging (Combining)
