Simulated Tree Branch Structure with Pull Rods to Prevent Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulated trees suffer from appearance instability due to deformation and dislocation of branches under external forces, leading to insufficient stability.
Innovation Solution
The simulated tree design includes decorative units with cylindrical main trunks, obliquely arranged connection columns, and pull rods connected between the connection columns and the main trunk, enhancing structural strength and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If branches are made thicker or reinforcing ribs are arranged on outer peripheral surfaces to improve appearance stability, then structural strength is enhanced, but the size of decorative twigs and leaves must be changed adaptively, making existing decorative twigs and leaves incompatible
Solution Approach 1:
The branch is divided into multiple connection columns distributed along the branch axis. Each connection column independently supports decorative twigs and leaves, allowing the branch to maintain structural strength through distributed support while preserving the original interface for mounting existing decorative elements without requiring size changes.
Solution Approach 2:
Instead of increasing branch thickness in the radial direction (one dimension), the patent distributes multiple connection columns along the branch axis (another dimension). This transforms the structural reinforcement approach from radial thickening to axial distribution, maintaining compatibility with existing decorative twigs and leaves while achieving enhanced structural strength.
2Reliability
If decorative twigs and leaves are subjected to external force or are too heavy, then the branches deform and fall off, but increasing branch thickness requires changing the size of decorative twigs and leaves
Solution Approach 1:
The branch is segmented into multiple connection columns that independently bear loads from decorative twigs and leaves. This segmentation distributes the mechanical stress across multiple points, enhancing reliability and appearance stability without requiring excessive thickening of individual branch sections, thus avoiding unnecessary structural complexity.
3Stability of the object's composition
If the entire branch rotates about the trunk or deforms under external force, then appearance stability is compromised, but traditional reinforcement methods require changing decorative twig and leaf sizes
Solution Approach 1:
Multiple connection columns are distributed along the branch axis, creating multiple attachment points for decorative twigs and leaves. This segmentation provides distributed structural support that resists branch rotation and deformation while maintaining the original mounting interface, ensuring compatibility with existing decorative elements without compromising appearance stability.

AI summary
The disclosure provides a simulated tree, and belongs to the technical field of simulated decorations. The simulated tree includes a plurality of decorative units capable of being inserted end to end in sequence, where each decorative unit includes a main trunk in a cylindrical shape, a plurality of connection columns are integrally arranged on an outer peripheral surface of the main trunk, and the connection columns are obliquely arranged from inside to outside in a radial direction of the main trunk towards a top of the main trunk; and pull rods are integrally connected between all or some of the connection columns and the main trunk of at least one decorative unit, and joints between the pull rods and the connection columns are positioned in middles of the connection columns. The appearance stability of the simulated tree is improved.
