Carrycot Bayonet Attachment for Secure Multi-Configuration Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child carriers, such as carrycots, lack efficient and versatile attachment mechanisms to securely couple to support frames like strollers or stands, compromising stability and ease of use.
Innovation Solution
A carrycot with attachment features, including bayonet receptacles and plungers, that removably attach to support frames, ensuring stability and ease of transition between configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional attachment features are used, then the carrycot can be attached to a stroller, but the attachment mechanism lacks stability and security
Solution Approach 1:
The attachment mechanism is divided into separate functional components: bayonet receptacles integrated into the support frame and corresponding bayonet attachment features on the carrycot. This segmentation allows each component to be optimized independently while working together to provide secure attachment.
Solution Approach 2:
The bayonet attachment mechanism serves multiple functions: it provides secure mechanical attachment, enables easy detachment, and allows for versatile configuration options (stroller attachment, stand attachment, or independent use). This multi-functionality resolves the contradiction by providing reliable attachment without requiring separate mechanisms for different use cases.
2Reliability
If the carrycot is designed for secure attachment, then stability is improved, but ease of transition between configurations is reduced
Solution Approach 1:
The attachment mechanism transitions from a static, permanent connection to a dynamic, reversible connection. The bayonet design allows the carrycot to be quickly attached and detached, enabling easy transition between different configurations (stroller mode, stand mode, or independent carrycot use) while maintaining secure attachment during use.
Solution Approach 2:
The bayonet receptacles and attachment features are pre-positioned and pre-oriented during manufacturing, allowing users to simply align and push the components together for secure attachment. This preliminary preparation eliminates complex alignment procedures and enables rapid configuration changes.
3Ease of operation
If simple attachment features are used, then ease of operation is improved, but attachment reliability is compromised
Solution Approach 1:
The bayonet mechanism acts as an intermediary between the simple act of pushing components together and the complex requirement for secure attachment. The bayonet's geometric design inherently provides mechanical locking and stability through its shape and engagement geometry, eliminating the need for additional complex locking mechanisms while maintaining both ease of operation and attachment reliability.

AI summary
In one example, a carrycot couples to a support frame to support the carrycot above a support surface. The carrycot has a carrycot frame having a first side and a second side that are spaced from one another so as to define a space therebetween that supports a child therein. The carrycot has a set of attachment features that is disposed at the first side and removably attaches to a bayonet of the support frame. The set of attachment features includes (1) a bayonet receptacle that receives a first portion of the bayonet and (2) a plunger that is spaced below the bayonet receptacle with respect to a vertical direction and is configured to engage an opening in a second portion of the bayonet.
