Conformal power adapter for lighted artificial tree
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pre-lit artificial trees with LED lighting face challenges in power management, including multiple cords and adapters that are inconvenient, unsightly, and prone to falling out of outlets, especially when trying to power both the tree and ornaments that require alternating-current (AC) power.
Innovation Solution
A conformal power adapter is designed to fit within the hollow trunk of an artificial tree, converting external power from an alternating current (AC) source to direct current (DC) and providing dual outputs, allowing for efficient and aesthetically pleasing power distribution to the tree's lighting elements and ornaments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple adapters and cords are used to power LED light strings, then power conversion to DC is achieved, but the appearance is degraded and convenience is reduced due to multiple plugs and cords being visible and prone to falling out
Solution Approach 1:
The patent combines multiple power adapters into a single integrated adapter unit that can power multiple LED light strings simultaneously. This single adapter replaces what would traditionally require multiple separate adapters and cords, eliminating the inconvenience of managing multiple plugs while maintaining reliable power delivery to all light strings.
Solution Approach 2:
The adapter is designed with universal functionality to power both LED light strings and AC-powered ornaments through multiple output ports. This multi-functional design allows a single adapter to handle diverse power needs (DC for LEDs, AC for ornaments) that would traditionally require separate power sources, improving convenience without sacrificing reliability.
2Adaptability or versatility
If multiple cords are placed around the tree to power different components, then all components receive power, but the aesthetic quality is degraded due to visible cords and adapters
Solution Approach 1:
The patent consolidates multiple power distribution functions into a single adapter unit with multiple output ports. This allows all power connections to originate from one location rather than having multiple cords distributed around the tree, maintaining aesthetic appearance while preserving the ability to power multiple components.
Solution Approach 2:
The adapter is designed to be concealed within the tree structure (hidden in branches or trunk), extracting the visible power management components from the aesthetic view. This allows the power distribution functionality to remain while the visual impact is eliminated, as the adapter and cords are hidden from view.
3Power
If wall-outlet adapters are used to provide power, then power conversion is achieved, but the adapter tends to fall out of vertical outlets and occupies excessive space
Solution Approach 1:
The patent integrates the power conversion function directly into the adapter unit that also contains the outlet connections. This integrated design eliminates the need for separate wall-outlet adapters that are prone to falling out, as the power conversion and connection functions are combined in a single stable unit that can be securely positioned.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces the visibility of cords and adapters, enhances safety by hiding critical wires, improves heat dissipation, and provides stability and convenience by using a single cord and plug, while ensuring reliable power delivery to both the tree and ornaments.
