Solution Overview

Problem

Existing artificial Christmas trees with pre-lit branches face challenges in maintenance and manufacturing due to integrated lighting designs, which make it difficult for consumers to replace faulty lights and require high skilled labor for uniform lighting, leading to increased costs and waste.

Innovation Solution

The design of releasably connected pre-lit branch assemblies with detachable wiring and wireless power transmission allows for easy replacement of branches and reduces manufacturing complexity, enabling separate production of lighted branches and tree components, thereby simplifying maintenance and reducing shipping costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pre-lit branches are integrated into the tree design, then the tree provides uniform and consistent lighting, but it becomes difficult and time-consuming to replace faulty lights

Engineering Contradiction:
Improvelighting consistencyVSAvoidlight replacement difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The tree is divided into separate modular components: pre-lit branch assemblies that can be detached and replaced independently from the tree pole. Each branch assembly includes its own integrated lighting, allowing consumers to replace only the faulty branch rather than the entire tree or complex wiring systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lighting system is extracted from the branch structure and integrated as a unified pre-lit assembly that can be removed as a single unit. This extraction allows the entire lighted branch to be replaced by simply detaching the connector, eliminating the need to manually replace individual lights or strings.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If branches are hinged and pre-lit at the factory, then consumer setup is easier, but maintenance and light replacement become more difficult

Engineering Contradiction:
Improveconsumer setup easeVSAvoidmaintenance difficulty
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The branch assembly is segmented into a hinged mechanical structure that folds for compact shipping but extends for display. The electrical connector is segmented as a separate detachable component, allowing the branch to be mechanically attached to the pole while electrically connected through a plug-and-receptacle interface that can be easily disconnected for maintenance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The branch connector incorporates a dynamic locking mechanism that secures the branch to the pole during operation but can be easily released by the consumer. The electrical connection dynamically engages when the branch is attached and disengages when removed, providing both stability during use and ease of maintenance.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If skilled labor is used for uniform lighting installation, then lighting quality is high, but manufacturing costs increase

Engineering Contradiction:
Improvelighting uniformityVSAvoidmanufacturing cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The lighting is pre-installed and pre-positioned on the branches during manufacturing, creating finished pre-lit branch assemblies. This preliminary action ensures uniform lighting distribution is achieved during controlled factory conditions rather than requiring skilled field installation, reducing both labor costs and the skill level needed at distribution centers.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Multiple identical pre-lit branch assemblies are manufactured using standardized processes and components. This copying approach allows lighting to be uniformly applied through replication of proven designs rather than requiring skilled workers to manually install and adjust each branch, reducing labor costs while maintaining consistency.

Inventive Principle:
Principle #26Copying

4Reliability

If entire trees are shipped to market, then product availability is ensured, but shipping costs and fuel consumption increase

Engineering Contradiction:
Improveproduct availabilityVSAvoidshipping fuel consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The tree is segmented into separate components (pole sections and pre-lit branch assemblies) that can be manufactured independently at different locations. Branch assemblies can be produced locally or regionally and then shipped only to nearby distribution centers, reducing long-distance shipping requirements while ensuring product availability through distributed inventory.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pre-lit branch assemblies are designed to nest compactly during shipping, folding into a space-efficient configuration that maximizes container utilization. This nesting capability reduces the volume required for shipping branches, lowering fuel consumption and shipping costs while maintaining the ability to quickly assemble complete trees at distribution points.

Inventive Principle:
Principle #7Nested doll (Nesting)
