Christmas tree with rotatable decorative lamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Christmas tree designs, particularly large and heavy ones, are unable to rotate their decorative lamps effectively, limiting the aesthetic appeal and fun of the product.
Innovation Solution
A Christmas tree with a rotatable decorative lamp featuring a drive motor, transmission gear component, and magnetic connectors that allow the decorative lamp to rotate independently of the tree body, using a transmission shaft and gears to drive the rotation of a five-pointed star-shaped lamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire Christmas tree is rotated to make the decorative lamp visible from different angles, then the decorative lamp can be viewed from all directions, but large and heavy Christmas trees cannot be rotated due to their size and weight
Solution Approach 1:
The patent divides the Christmas tree system into two independent parts: the stationary tree body and the rotatable decorative lamp. The decorative lamp is mounted on a rotatable support structure that can rotate independently from the tree body, allowing the lamp to be viewed from different angles without moving the entire heavy tree.
Solution Approach 2:
The patent introduces a rotatable support structure with manual or automatic rotation capability for the decorative lamp. This dynamic element allows the lamp to change orientation and be viewed from different angles, transforming a static display into a dynamic one without requiring tree rotation.
2Ease of operation
If a magnetic suspension system is used to rotate the entire Christmas tree, then the decorative lamp can rotate on small trees, but this solution is not applicable to large and heavy Christmas trees
Solution Approach 1:
The patent separates the rotation function from the entire tree system and applies it only to the decorative lamp component. This segmentation makes the rotation mechanism independent of tree size, allowing small, medium, and large trees to all benefit from the rotation capability without requiring the entire tree to be movable.
Solution Approach 2:
The rotatable support structure provides a dynamic rotation mechanism specifically for the decorative lamp, making the system adaptable to trees of various sizes. The rotation capability is built into the lamp mounting system rather than the tree base, enabling universal application across different tree scales.
3Illumination intensity
If LED light emitting tubes are guided through the interior of branches from top to root, then uniform illumination is achieved, but the decorative lamp on top cannot rotate
Solution Approach 1:
The patent separates the lighting system into two independent components: LED light emitting tubes embedded in the tree branches for uniform illumination, and a separate rotatable decorative lamp on top with its own rotation mechanism. This segmentation allows both uniform tree illumination and lamp rotation to coexist without interference.
Solution Approach 2:
The patent introduces a dynamic rotatable support structure for the decorative lamp that operates independently from the static illuminated tree body. The rotation mechanism allows the lamp to change orientation while the LED tubes continue to provide uniform illumination throughout the tree branches.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the decorative lamp to rotate and illuminate without rotating the entire tree, enhancing user engagement and enjoyment.
Implementation Method 1
a drive motor (4) fixedly mounted inside the housing (3)
Implementation Method 2
A first magnetic connector (11) is mounted inside the through hole of the shaft sleeve (10) through a bearing. The rotatable lamp (15) includes a column body (13) that can be fixed to the shaft sleeve (10) through clamping. The column body (13) has a bottom surface fixedly connected to a second magnetic connector (14)

AI summary
The present disclosure provides a Christmas tree ornament, aiming to provide a Christmas tree with a rotatable decorative lamp. The key points of the technical solution are that the Christmas tree includes a tree body and a rotatable lighting unit positioned on an upper end of the tree body. The rotatable lighting unit includes a housing, a drive motor fixedly mounted inside the housing, a transmission gear component moveably mounted inside the housing and a rotatable lamp moveably mounted on the housing. The drive motor is provided thereon with a transmission shaft connected thereto in a transmission manner. The transmission shaft has an upper end fixedly connected to a lower gear. The lower gear is provided on one side with the transmission gear component connected thereto in a transmission manner. The lower gear has an upper end sleeved with a dedicated inner sheath.
