Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible carry cots lack an efficient mechanism for adjusting height and compact storage, making them inconvenient for transporting infants as they grow and for storage in limited spaces.
Innovation Solution
A collapsible carry cot design featuring a scissor linkage mechanism between first and second frame members, with a securing mechanism that allows adjustable height and compact folding, enabling secure positioning and easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a collapsible carry cot is designed with a scissor linkage mechanism for height adjustment, then the adaptability for growing infants is improved, but the device complexity increases
Solution Approach 1:
The carry cot employs a scissor linkage mechanism that enables dynamic height adjustment of the side walls. The first and second frame members are pivotally coupled to allow relative movement, transforming the structure from static to dynamic. This enables the side wall height to be adjusted between extended and retracted positions, providing adaptability for infants of different ages and sizes while maintaining a manageable mechanical structure through standardized linkage geometry.
2Volume of moving object
If the carry cot is designed to collapse into a compact form for storage, then the ease of storage is improved, but the reliability of structural stability during use may worsen
Solution Approach 1:
The carry cot structure is segmented into multiple pivotally connected frame members (first frame member, second frame member, base member) that can independently move relative to each other. This segmentation allows the structure to be divided into extended configuration during use and collapsed configuration for storage. The pivotal connections act as segmentation joints that enable both structural integrity when extended and compact folding when collapsed.
Solution Approach 2:
The collapsible mechanism allows the second frame member to nest within or alongside the first frame member when collapsed, similar to nested dolls. The scissor linkage enables the frame members to fold into each other, reducing the overall volume to a compact form suitable for storage in limited spaces while maintaining the ability to fully extend to provide structural stability during use.
3Reliability
If a securing mechanism is added to restrict sliding of frame members, then the reliability of position maintenance is improved, but the ease of operation worsens
Solution Approach 1:
The securing mechanism is designed to automatically engage and disengage based on the position of the frame members. As the second frame member slides relative to the base member, the securing mechanism self-activates to lock the position when extended or retracted, eliminating the need for manual intervention. The mechanism uses the movement itself to trigger the locking action, maintaining reliability while preserving ease of operation.
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 allows for adjustable height to accommodate growing infants and efficient storage by collapsing into a smaller space, enhancing usability and storage convenience.
Implementation Method 1
the first and second frame members are pivotally coupled together such that pivoting the first and second frame members relative to one another changes a height of the side and/or end wall of the carry cot
Implementation Method 2
the second frame member is pivotally and slideably movable relative to the base member
Implementation Method 3
the engagement element is movable relative to the base member in a direction with a component in a lateral direction of the carry cot

AI summary
A collapsible carry cot (100) comprises: a base member (210); first and second frame members (230, 240), wherein the first and second frame members together at least partially define a side or end wall of the carry cot, and wherein the first and second frame members are pivotally coupled together such that pivoting the first and second frame members relative to one another changes a height of the side or end wall of the carry cot, wherein the first frame member (230) is pivotally movable relatively to the base member (210) and the second frame member (240) is pivotally and slideably movable relative to the base member (210); and a securing mechanism (300), the securing mechanism to releasable secure the second frame member relative to the base member, such that sliding of the second frame member (240) relative to the base member (210) is restricted, thereby restricting pivoting of the first frame member (230) relative to the second frame member (240).
