Child seating device and support frame thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current child seating devices, such as cribs, seats, and carry cots, are fixedly mounted on stands, limiting their versatility and making it difficult to change their mode of use or store them efficiently, as they can only be unfolded or folded in a single way.
Innovation Solution
A support frame with unfolding and folding joints, bearing bases, and two stands that can be connected pivotally, allowing for multiple modes of use and easy folding or unfolding, facilitated by a joint engaging piece that locks and releases the pivotal rotation between the stands, and an elastic element to drive the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If child carriers are fixedly mounted on stands, then the structure is stable and reliable, but the device lacks versatility and cannot be used in multiple modes
Solution Approach 1:
The child carrier is divided into separable components: the carrier body can be detached from the stand through the unfolding and folding joint mechanism. The joint itself is segmented into locking and unlocking states, allowing the system to transition between fixed and mobile configurations, thereby achieving both stability when mounted and versatility when detached.
Solution Approach 2:
The stand incorporates dynamic unfolding and folding joints that allow the structure to transition between fixed and mobile states. The joint mechanism enables the stand to adapt its configuration dynamically - locked in place for stable mounting or folded for portable storage - resolving the contradiction between fixed stability and versatile adaptability.
2Volume of moving object
If the stand is made into an unfolding and folding operation to save space, then storage efficiency is improved, but the non-disassemblable property limits the stand to a single mode of use
Solution Approach 1:
The stand is designed with universal multi-functionality through the detachable joint mechanism. It can serve multiple purposes: providing stable support when unfolded and locked, enabling portable storage when folded, and allowing complete disassembly for versatile use with different child carriers. The unfolding and folding joint transforms a single-mode structure into a multi-functional system.
3Reliability
If the child carrier is fixedly mounted on the stand, then the mounting is stable and reliable, but it becomes non-disassemblable and difficult to store
Solution Approach 1:
The joint mechanism incorporates preliminary locking action that automatically secures the child carrier to the stand when mounted, providing immediate stability. The elastic element pre-positions the locking piece to engage with the positioning groove, ensuring reliable mounting without complex assembly steps. For disassembly, the operating piece is designed to easily release the lock, facilitating simple detachment and storage.
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
Enables the support frame to be used with different child carriers like cribs, carry cots, or seats and facilitates storage by allowing the stands to be folded or unfolded as needed, providing versatility and efficient storage solutions.
Implementation Method 1
an elastic element, which is used to drive the joint engaging piece, so that the joint engaging piece moves to the locking position
Implementation Method 2
the second stand is connected pivotally to the first stand with the aid of the unfolding and folding joints
Data Source
AI summary
The disclosure provides a support frame of a child seating device having unfolding and folding joints, bearing bases, a first stand and a second stand. The bearing base is formed on the unfolding and folding joint; the first stand is assembled with the unfolding and folding joints, the second stand is assembled with the unfolding and folding joints, and the second stand is connected pivotally to the first stand with the aid of the unfolding and folding joints. With the aid of the bearing bases, the support frame of the child seating device of the disclosure can be detached from or engaged with different child carriers, so that the support frame of the child seating device of the disclosure has multiple modes of use. In addition, the disclosure also provides a child seating device.
