Christmas tree stand and assembled support assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Christmas tree stands face stability issues on uneven ground and are inconvenient to place, with existing designs either lacking stability or requiring excessive structural strength.
Innovation Solution
A cross-shaped Christmas tree stand with a support assembly comprising multiple tree stand members that can be assembled without tools or adhesives, featuring a second support portion that bears the tree's weight and a first support portion for stabilization, allowing for deformation to adjust to the ground surface for improved stability and reduced material requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a Christmas tree stand has a planar bottom surface structure, then it has a large contact area with the ground and is relatively stable, but it is liable to shake when the ground is poorly flat
Solution Approach 1:
The bottom surface is segmented into multiple fulcrums (at least three) instead of a continuous planar surface. Each fulcrum can independently contact the ground, allowing the structure to adapt to uneven surfaces while maintaining stability through the distributed contact points.
Solution Approach 2:
The fulcrums are designed to be adjustable in position and angle, enabling dynamic adaptation to different ground conditions. This allows the tree stand to be configured for optimal stability on various types of surfaces, from flat to highly uneven ground.
2Adaptability or versatility
If a Christmas tree stand has a fulcrum-like bottom surface structure with three or more fulcrums, then it has better compatibility with uneven ground, but it is inconvenient to place and requires increased structural strength for each leg
Solution Approach 1:
The tree stand members are designed with self-shaping capability through the interaction of rotation limiting members and upper-lower limiting mechanisms. When assembled, the structure automatically adjusts to find stable contact with the ground, eliminating the need for manual positioning or adjustment by the user.
3Ease of manufacture
If tree stand members are assembled without tools or adhesives using rotation limiting members and upper-lower limiting mechanisms, then assembly is facilitated and packaging volume is reduced, but the assembly portion requires precise fitting
Solution Approach 1:
Rotation limiting members and upper-lower limiting mechanisms serve as intermediary components that facilitate assembly without requiring tools or adhesives. These mechanisms provide built-in guidance and constraint, making the assembly process intuitive while accommodating reasonable manufacturing tolerances.

AI summary
The disclosure relates to a Christmas tree stand and an assembled support assembly, where the Christmas tree stand comprises a tree stand support assembly and a connector, the tree stand support assembly is formed by assembling a number of tree stand members with each other, and enables the tree stand members to be self-shaped after assembly without using other tools by means of an inside assembly structure, thereby facilitating assembly of the Christmas tree stand, and the split type tree stand members are also advantageous in packaging and transportation after disassembly.
