Foldable Tree Stand with Hinged Support Arms for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative trees, such as Christmas trees, face challenges with large volume that complicates transportation and storage due to the need for a substantial tree stand to enhance visual effect.
Innovation Solution
A tree stand with a telescopic pole assembly, support arms that can be unfolded or folded, and a locking mechanism allowing the support arms to be stably locked in the unfolded state for display and locked in the folded state for storage, reducing overall volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the tree stand is designed with a large overall volume to enhance visual effect, then the decorative effect is improved, but the convenience of transfer and storage space are worsened
Solution Approach 1:
The support arm is designed as a movable component that can switch between an unfolded state (for display) and a folded state (for storage and transfer). The movable base allows the support arm to be positioned and locked at different angles, transforming the rigid structure into a dynamic one that adapts to different functional requirements.
Solution Approach 2:
The tree stand is divided into separable components: a pole assembly, a movable base, and a support arm with decoration. This segmentation allows the support arm and decoration to be folded or removed, reducing the overall volume for storage while maintaining the complete structure for display.
2Shape
If the tree stand is designed with a large overall volume to enhance visual effect, then the decorative effect is improved, but the storage space required is worsened
Solution Approach 1:
The support arm transitions from a static large-volume configuration during display to a dynamic folded configuration during storage, significantly reducing the space occupied while maintaining structural integrity and aesthetic appearance when deployed.
Solution Approach 2:
When folded, the support arm and decoration can be nested or compacted along the pole assembly, similar to a nested doll structure, minimizing the storage volume while preserving the ability to expand to full size for display.
3Volume of stationary object
If the support arm is hinged to allow folded and unfolded states, then the volume reduction capability is improved, but the stability when unfolded is worsened
Solution Approach 1:
The locking mechanism is designed to automatically or manually secure the support arm in the unfolded state before use, ensuring stability is established in advance. The locking member engages with a locking recess to prevent any unintended movement or folding during the display period.
4Stability of the object's composition
If the locking mechanism is added to secure the support arm, then the stability when unfolded is improved, but the device complexity is worsened
Solution Approach 1:
The locking function is extracted as a separate, simple mechanism (locking member and locking recess) that can be independently operated. This modular approach adds minimal complexity while providing effective stability, and the locking mechanism can be engaged or disengaged as needed without affecting other components.

AI summary
The present application relates to a decorative tree and a tree stand thereof. The tree stand includes: a pole assembly (110) configured to support a decoration (30); a support mechanism (120) fixed on the pole assembly; a support arm (130) hinged to the support mechanism and having a unfolded state and a folded state; a movable base (140) movably disposed on the pole assembly and operably connected to the support arm to drive the support arm to switch between the unfolded state and the folded state; and a first locking mechanism (150) disposed on the movable base and having a locked state and an unlocked state. When in the locked state, the first locking mechanism is capable of locking the support arm in the unfolded state; and when in the unlocked state, the first locking mechanism is capable of unlocking the movable base from the unfolded state. The support arms have the unfolded state and the folded state by hinging the support arm to the support mechanism, so that the overall volume of the tree stand can be changed. In this way, when the tree stand is transferred or stored, the support arms can be maintained in the folded state to reduce the overall volume of the tree stand, thereby saving the space during storage and transportation.
