Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ornamental lighting systems, such as pre-lit Christmas trees, require manual and cumbersome connections of power strings between sections, which is inefficient and inconvenient for users.
Innovation Solution
A central pole system composed of two segments with a two-part joint that includes connector parts and apertures, allowing for automatic physical and electrical connection of pole segments, ensuring alignment and secure engagement through guide keyways and resilient arms, and optionally using removable electrical connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual power connections are made by digging into dense tree structures, then power strings can be connected between sections, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The pole is divided into multiple sections that can be shipped separately and assembled by the user. The power connection system is also segmented with separate male and female connectors that engage automatically when sections are joined, eliminating the need for manual wiring operations.
Solution Approach 2:
Power connectors are pre-installed on the pole sections during manufacturing. The electrical connection path is prepared in advance with conductive elements positioned within the pole structure, so that when sections are assembled, power flow is automatically established without requiring users to dig into or modify the tree structure.
2Ease of operation
If simple power plugs are hung from branches, then power connection is simplified, but the connection is not secure and may become disconnected
Solution Approach 1:
The mechanical pole connection and electrical power connection are merged into a single integrated operation. When two pole sections are joined together, both the structural support and the electrical conductors are connected simultaneously through the integrated connector system, ensuring that power flow is reliably established as part of the normal assembly process.
Solution Approach 2:
An intermediary connector system is introduced that bridges both the mechanical and electrical connection functions. The connector includes structural elements for pole alignment and retention, as well as embedded conductive elements that establish electrical contact, serving as a mediator that handles both physical support and power transmission in a unified mechanism.
3Volume of moving object
If the pole is divided into multiple sections for shipping, then height is reduced for storage, but additional connection operations are required during assembly
Solution Approach 1:
The connector design provides multi-functionality by simultaneously handling mechanical pole section joining and electrical power connection. This universal connector eliminates the need for separate operations for structural assembly and electrical wiring, reducing overall assembly complexity despite the need for section joining.
Solution Approach 2:
The connector system performs self-alignment and self-connection features. The tapered guide keys automatically align the pole sections and connectors during insertion, and the resilient arms automatically establish electrical contact when sections are joined, allowing the system to service itself during assembly without requiring complex manual intervention or specialized tools.

AI summary
A central shaft power connector for lighted ornaments is disclosed. A central support pole, such as for a Christmas tree is made in multiple parts joinable with an electrical and mechanical connector which joins the pole parts and simultaneously connects power or other circuits from one part to the other. The connector has two engaging sections and an outrigger platform which locates a connector off to the side of the poles but in alignment. Final alignment is obtained by a key and keyway in the connector parts. The connector is friction fit into a slot on each section so that the connector can be removed and replaced.
