Foldable support device and artificial tree
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices are bulky and inconvenient to transport due to their fixed radial structures, which can easily get damaged during handling.
Innovation Solution
A foldable support device with a first locking mechanism that allows the support leg assembly to switch between folded and unfolded states, utilizing an engaging seat and engaging pin to lock and unlock the assembly, and a second locking mechanism to maintain the unfolded position, reducing storage and transportation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support device uses a fixed radial structure, then the support structure is stable and simple, but the device becomes large in volume and inconvenient for storage and transportation
Solution Approach 1:
The support leg assembly is designed to be movable relative to the support base through a hinged connection, allowing the structure to dynamically change between extended and folded positions. This dynamic design enables the support device to reduce its volume for storage while maintaining structural stability during use through locking mechanisms.
Solution Approach 2:
The support device is divided into separable components: a support base, a movable support leg assembly, and locking mechanisms. This segmentation allows the support leg to be independently folded and stored, reducing overall volume while maintaining the integrity and stability of each component during operation.
2Device complexity
If the support device uses a fixed radial structure, then the structure is simple, but the device is easy to damage during handling and inconvenient to carry
Solution Approach 1:
The hinged connection between the support leg assembly and support base enables the structure to adapt to different handling conditions. When folded, the device becomes more compact and less prone to damage during transport, while the locking mechanisms ensure structural integrity and reliability during use.
Solution Approach 2:
The locking mechanisms are designed to automatically engage and secure the support leg assembly in both extended and folded positions. This preliminary locking action prevents accidental movement or damage during handling and transportation, enhancing reliability without requiring complex additional structures.
3Volume of moving object
If the support leg assembly is made foldable, then the storage space is reduced, but the device complexity increases due to locking mechanisms
Solution Approach 1:
The locking mechanisms are designed to automatically engage and disengage based on the position of the support leg assembly. The first locking mechanism automatically locks the folded position, while the second locking mechanism secures the extended position, eliminating the need for manual locking operations and reducing operational complexity despite the added structural components.
Solution Approach 2:
Multiple locking functions are integrated into a unified system where the first and second locking mechanisms work together with the hinged connection to provide seamless transition between folded and extended states. This merging of functions reduces the overall complexity compared to having separate independent locking systems for each state.

AI summary
The embodiment of the present disclosure provides a foldable support device and an artificial tree, which includes a support base(11), a support leg assembly (2) and a first locking mechanism (3). The support base is provided with a hinged portion (12) and a mounting portion (11) configured to mount an object to be supported. The support leg assembly is hinged to the hinged portion. The first locking mechanism is movably disposed on the support base. The first locking mechanism includes a locking state in which the support leg assembly is locked in a folded state and an unlocked state in which the support leg assembly is unlocked from the folded state. The support device can be easily switched between the folded state and the unfolded state. Meanwhile, when the support device is in a non-use state, the storage space and the transportation space can also be saved.
