Decorative tree and tree stand thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative lighted trees occupy a large volume during transportation and storage due to their cumbersome unfolding and folding processes.
Innovation Solution
A tree stand with a pole assembly, support arms, and movable mounting members that allow the decorative mesh to switch between expanded and collapsed states through a locking mechanism, simplifying the unfolding and folding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the decorative tree is designed with a large overall volume to enhance decorative effect, then the decorative functionality is improved, but the space occupied during transportation and storage increases
Solution Approach 1:
The patent implements a dynamic folding mechanism where the support arms can rotate between extended and retracted positions. The mounting members allow the decorative mesh to be adjusted between expanded and collapsed states, enabling the tree to transition from a large decorative volume to a compact storage configuration
Solution Approach 2:
The tree structure is divided into separable components including multiple support arms, a pole assembly, and a decorative mesh. The mounting members enable independent adjustment of each support arm, allowing the structure to be folded segment by segment for compact storage while maintaining the complete decorative form when assembled
2Volume of moving object
If the decorative tree is designed as a foldable structure to reduce transportation and storage space, then the volume for storage is reduced, but the unfolding and folding process becomes cumbersome
Solution Approach 1:
The mounting members are pre-configured with locking portions and engaging portions that automatically align during the folding process. The limit holes and limit protrusions are positioned to automatically engage at predetermined locations, eliminating the need for manual alignment or complex locking operations during folding and unfolding
Solution Approach 2:
The folding mechanism utilizes gravity and the geometric arrangement of limit holes and limit protrusions to automatically guide the support arms into their folded positions. The mounting members self-lock when the limit protrusions engage with the limit holes, eliminating the need for external locking mechanisms or complex operational steps

Function Achieved in This Case
The tree stand simplifies the unfolding and folding of decorative trees, reducing their volume for storage and transportation, and enhancing decorative functionality.
Implementation Method 1
When the second mounting member is separated from the first mounting member, the second mounting member automatically moves to the bottom end of the pole assembly under gravity

AI summary
The present application relates to a decorative tree and a tree stand thereof. The tree stand includes: a pole assembly, support arms connected to a bottom end of the pole assembly and configured to be connected to a bottom of a decorative mesh; a first mounting member mounted on a top end of the pole assembly and including a locking portion; and a second mounting member movably disposed on the pole assembly and configured to be connected to a top of the decorative mesh. The second mounting member includes an engaging portion configured to be engaged with the locking portion to limit a movement of the second mounting member relative to the pole assembly.
