Solution Overview

Problem

Existing decorative trees, such as Christmas trees, suffer from unstable ornament attachment methods that lead to frequent fall-offs and low decoration efficiency.

Innovation Solution

A branch structure with a hook featuring a bent portion that allows direct hanging of ornaments, enhancing stability and reducing the risk of fall-off through a limiting groove and guiding mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ornaments are hung on branches in a winding manner, then the decorative tree can be assembled, but the ornament attachment is unstable and ornaments are prone to fall-off

Engineering Contradiction:
Improveornament attachment stabilityVSAvoiddecoration efficiency
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention divides the branch structure into modular components: branch body, hook, and to-be-placed object. The hook is further segmented into first rod body, second rod body, limiting protrusion, and guide portion. This segmentation allows each component to perform its specific function independently, with the hook providing stable attachment while maintaining ease of assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hook serves as an intermediary component between the branch body and the to-be-placed object. It mediates the attachment function by providing a structured interface with limiting grooves and guide portions, transforming the unstable winding manner into a stable hooked attachment that is both reliable and easy to operate.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If ornaments are attached using traditional winding method, then decoration can be applied, but installation time is excessive and decoration efficiency is low

Engineering Contradiction:
Improvedecoration efficiencyVSAvoidinstallation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The hook structure is pre-configured with limiting grooves and guide portions during manufacturing. This preliminary action eliminates the need for complex winding operations during decoration, allowing ornaments to be quickly attached by simply hooking them onto the pre-formed structure, thereby significantly reducing installation time and improving productivity.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a simple hook structure is used, then installation is quick, but ornament stability may be insufficient

Engineering Contradiction:
Improveinstallation speedVSAvoidornament stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The hook employs asymmetric design with the first rod body and second rod body arranged at specific angles, creating an asymmetric limiting groove configuration. The limiting protrusion is positioned asymmetrically to provide one-way retention. This asymmetric structure enables quick installation while ensuring ornament stability through directional constraint.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The guide portion features curved surfaces that guide the to-be-placed object smoothly into the limiting groove. The circular arc transitions at junctions provide smooth guidance while the overall curved hook shape naturally accommodates spherical or rounded ornaments, enhancing stability through geometric compatibility.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

The present disclosure relates to a decorative tree and a branch structure thereof. The branch structure (10) includes a branch body (110) and a hook (120) mounted on the branch body (110). The hook (120) has a bent portion (121) facing the branch body (110) and configured to support a to-be-placed object (20). When the branch structure is decorated with the to-be-placed object (e.g., an ornament), the to-be-placed object may be hung directly on the bent portion, thereby realizing quick installation of the to-be-placed object. In addition, the bent portion can also improve stability of the to-be-placed object after installation and reduce a risk of fall-off of the to-be-placed object.
