Collapsible Carrycot Three-Section Frame to Reduce Storage Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible carrycots occupy significant space due to the large opening angle of rod bodies distal to the folding joint after folding, and forced compression can damage the cloth cover components.
Innovation Solution
A collapsible carrycot design with upper and lower frames that can be folded in a three-section configuration, using collapsible parts and locking mechanisms to minimize space occupation and protect the cloth cover, featuring symmetrically arranged collapsible parts and connecting rods for stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the carrycot is folded using conventional two-section folding, then the folding mechanism is simple, but the end of the rod bodies distal to the folding joint has a large opening angle that occupies significant space
Solution Approach 1:
The lower frame body is divided into three sections (first, second, and third lower frame bodies) instead of conventional two sections. This segmentation allows the distal ends of the rod bodies to be positioned closer together after folding, reducing the opening angle and minimizing the space occupied by the folded carrycot.
Solution Approach 2:
The folding mechanism incorporates both longitudinal folding (along the length of the carrycot) and lateral folding (across the width). This multi-dimensional folding approach allows for more compact packaging by reducing the opening angle in multiple directions simultaneously, thereby reducing overall storage space requirements.
2Ease of operation
If forced compression is applied to fold the carrycot, then the folding action can be completed, but the cloth cover soft component at the joint may be damaged
Solution Approach 1:
The cloth cover is strategically positioned and tensioned before the folding operation begins. This pre-positioning ensures that the cloth cover acts as a cushioning element during folding, absorbing compression forces and preventing damage to the soft component at the joint while still allowing the folding action to complete successfully.
Solution Approach 2:
The cloth cover serves as an intermediary element between the rigid frame components during folding. Rather than allowing direct compression between hard surfaces that could damage the soft cover, the cloth cover mediates the interaction, distributing forces evenly and protecting the soft component from concentrated compression damage.
3Ease of operation
If the cloth cover is removed before folding, then manual operation on the rods can be performed, but the folding process becomes extremely cumbersome and labor-intensive
Solution Approach 1:
The carrycot is designed so that the cloth cover itself facilitates the folding operation rather than hindering it. The cover's positioning and tensioning automatically guide the folding action, allowing the rods to be manipulated without removing the cover. This self-service design eliminates the need for cover removal while maintaining ease of operation on the rod components.
Solution Approach 2:
The cloth cover serves multiple functions simultaneously: it provides comfort and protection for the child, maintains the aesthetic appearance of the carrycot, and facilitates the folding operation by guiding and protecting the rod manipulation. This multi-functionality eliminates the need to remove the cover before folding, saving time and labor while maintaining all essential functions.
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 design reduces storage space requirements and minimizes damage to the cloth cover, providing a stable and reliable folding mechanism that is easy to operate and cost-effective.
Implementation Method 1
the first upper frame body and the second upper frame body are connected via the first foldable part and/or bendable part , and each of the first upper frame body and the second upper frame body is separately foldable toward each other around the connection points thereof to the first foldable part and/or bendable part as the rotation points
Implementation Method 2
the first lower frame body is rotatably connected to one end of the third lower frame body, the second lower frame body is rotatably connected to the other end of the third lower frame body, and each of the first lower frame body and the second lower frame body is separately foldable toward each other around the connection points thereof to the third lower frame body as the rotation points
Implementation Method 3
the collapsible assembly includes a first collapsible part between the first upper frame body and the first lower frame body, and a second collapsible part between the second upper frame body and the second lower frame body, and when the first upper frame body and the second upper frame body are folded toward each other, the first lower frame body and the second lower frame body are driven to be folded toward each other by the first collapsible part and the second collapsible part
