Collapsible carry cot
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 and storing as infants grow, and for accommodating upright seating positions.
Innovation Solution
A collapsible carry cot design featuring a scissor linkage mechanism with pivotally and slidably coupled frame members and a securing mechanism that allows for adjustable height and compact folding, enabling secure storage and easy conversion between upright and flat positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the carry cot is made collapsible with pivotally coupled frame members to reduce storage space, then the storage convenience is improved, but the structural complexity increases
Solution Approach 1:
The carry cot frame is divided into multiple segmentable components including first and second frame members that can pivot relative to each other, allowing the structure to be broken down into smaller parts for compact storage while maintaining structural integrity when assembled
Solution Approach 2:
The collapsible frame members are designed to nest within each other when collapsed, with the second frame member positioned inside or alongside the first frame member, creating a compact nested configuration that minimizes storage volume
2Adaptability or versatility
If the frame members are made adjustable in height to accommodate growing infants, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The frame members incorporate dynamic adjustment capabilities through pivotal connections that allow the second frame member to slide along the first frame member, enabling height adjustment to accommodate growing infants while maintaining a relatively simple overall structure
Solution Approach 2:
The adjustable frame mechanism serves multiple functions: it provides height adjustment for growing infants, enables collapsing for storage, and maintains structural support, thereby reducing the need for separate adjustment mechanisms
3Adaptability or versatility
If the second frame member is slidably movable relative to the base member to enable height adjustment, then the adaptability is improved, but the reliability of securing the structure decreases
Solution Approach 1:
The sliding connection between the second frame member and base member incorporates self-locking features that automatically secure the structure at desired positions, eliminating the need for separate locking mechanisms while maintaining both adjustability and reliability

AI summary
A collapsible carry cot includes a base member; first and second frame members, 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, and wherein the first frame member is pivotally movable relatively to the base member and the second frame member is pivotally and slidably movable relative to the base member; and a securing mechanism, the securing mechanism to releasable secure the second frame member relative to the base member, such that sliding of the second frame member relative to the base member is restricted, thereby restricting pivoting of the first frame member relative to the second frame member.
