Decorative trees and tree stand thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative lighted trees have large volumes due to their design, leading to space constraints during transportation and storage, and the unfolding and folding processes are cumbersome.
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
1Ease of manufacture
If the decorative tree is designed with a large overall volume to enhance decorative effect, then the decorative effect is improved, but the space occupied during transportation and storage increases
Solution Approach 1:
The patent applies the dynamics principle by designing the decorative tree as a foldable structure with movable mounting members. The tree can transition between an expanded state for decoration and a collapsed state for storage, making the volume dynamic rather than fixed. This resolves the contradiction by allowing the tree to have large volume when needed for decorative effect while reducing to small volume for transportation and storage.
Solution Approach 2:
The patent segments the tree structure into multiple support arms and mounting members that can be folded and collapsed. By dividing the overall structure into separable, movable components, the tree can be compacted into a smaller volume for storage while maintaining the full decorative volume when assembled and expanded.
2Volume of stationary object
If the decorative tree is designed as a foldable structure to reduce transportation and storage space, then the storage space is reduced, but the unfolding and folding process becomes cumbersome
Solution Approach 1:
The patent applies preliminary action by pre-configuring the mounting members with locking portions and engaging portions that automatically lock into place. The second mounting member is pre-designed to slide along the pole assembly and automatically engage with the first mounting member, eliminating the need for complex manual assembly steps and making the unfolding process simple and intuitive.
Solution Approach 2:
The locking mechanism is designed to be self-servicing through the interaction between the locking portion and engaging portion. When the second mounting member is moved to the top end of the pole assembly, it automatically engages with the first mounting member without requiring additional tools or complex operations, allowing the user to easily secure the tree in its expanded state.
3Ease of operation
If a locking mechanism is added to simplify the unfolding and folding process, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the locking function from a complex mechanism and implements it through simple geometric features - a locking portion and an engaging portion. By separating the locking function from complex mechanical systems and implementing it through basic interlocking shapes, the ease of operation is improved without significantly increasing device complexity.
Solution Approach 2:
The locking mechanism applies local quality by concentrating the locking function at specific locations (the locking portion and engaging portion) rather than distributing complexity throughout the entire structure. This localized approach to locking simplifies the overall device while maintaining ease of operation at the critical interaction points.

Function Achieved in This Case
The solution simplifies the unfolding and folding of decorative trees, reducing their volume for storage and transportation, and enhances operational efficiency.
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.
