Retractable Bracket for Artificial Trees to Reduce Ornament Falling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional artificial trees face issues with ornaments falling due to heavy ornaments being hung on long, soft branches, affecting aesthetics and requiring laborious placement.
Innovation Solution
A retractable bracket system with a fixed rod and a retractable rod, allowing for adjustable mounting positions to securely hang or place ornaments, reducing the risk of them falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ornaments are placed directly on long, soft branches, then placement is simple, but ornaments may fall and aesthetics are affected
Solution Approach 1:
The bracket is divided into a fixed rod and a retractable rod that can be independently adjusted. The retractable rod can be extended or retracted to different positions along the fixed rod, creating multiple discrete mounting positions for ornaments. This segmentation allows the bracket to provide stable support points while maintaining ease of use.
Solution Approach 2:
The retractable rod is designed to be movable relative to the fixed rod, allowing dynamic adjustment of the bracket's length and mounting position. The rod can be extended when ornament placement is needed and retracted or adjusted to secure positions for stability. This dynamic capability resolves the contradiction between ease of operation and ornament stability.
2Stability of the object's composition
If the bracket is fixed in position, then structural stability is maintained, but adaptability to different ornament sizes and positions is reduced
Solution Approach 1:
The retractable rod can be adjusted to different positions along the fixed rod and locked at multiple discrete positions. This dynamic adjustability allows the bracket to adapt to different ornament sizes and placement requirements while maintaining structural stability when locked in position. The rod's ability to move and lock provides both flexibility and stability.
Solution Approach 2:
The effective length and position of the bracket are changed by adjusting the retractable rod's position relative to the fixed rod. By changing the parameter of rod extension length, the bracket can accommodate different ornament configurations while maintaining a stable fixed structure. The parameter change enables versatility without compromising structural integrity.
3Ease of operation
If the bracket is made extendable for easier ornament placement, then ease of operation improves, but device complexity increases
Solution Approach 1:
The bracket is segmented into a simple fixed rod and a retractable rod with an abutting structure. This segmentation allows the extendable functionality to be added through a relatively simple modular component rather than redesigning the entire bracket structure, thus limiting the increase in overall device complexity while improving ease of operation.
Solution Approach 2:
The abutting structure serves as an intermediary mechanism between the retractable rod and the fixed rod. It provides a simple friction-based or mechanical interference fit that enables the retractable rod to be adjusted and locked without requiring complex locking mechanisms, motors, or control systems. This intermediary structure adds extendability while keeping the overall device complexity manageable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The retractable bracket system facilitates easy and secure hanging or placement of ornaments, enhancing the aesthetic appeal and reducing the risk of ornaments falling, while allowing for adjustable dimensions to accommodate various objects.
Implementation Method 1
Each resilient claw abuts against the inner wall of the inserted hole and is pressed by the inner wall of the inserted hole to create a friction between the resilient claw and the inner wall of the inserted hole
Implementation Method 2
The retractable rod is provided with an abutting structure which is elastically deformable and is capable of abutting an inner wall of the inserted hole

AI summary
The present disclosure relates to an artificial tree and a retractable bracket connected to a support device, which includes a fixed rod and a retractable rod. The fixed rod is connected to the support device. The retractable rod is movably connected to the fixed rod and capable of being fixed relative to the fixed rod in any desired position, such that a first mounting portion configured to hang or place an object to be placed is formed between the retractable rod and the fixed rod. An end of the bracket away from the support device is capable of being relatively elongated and shortened, making it easier to hang or place an object to be placed, such as an ornament, while reducing the risk of the object to be placed falling off.
