Snapping structure and baby carrier using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mating structures for mounting sleep boxes or baby seats to carriers like vehicle frames or bed frames are complex, occupy large space, and are inconvenient to operate.
Innovation Solution
A snapping structure with a movable locking member on the body and a positioning member on the support frame, allowing for easy attachment and detachment by telescopic movement, facilitated by a driving assembly and operating member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional mating structures are used to mount the body to the support frame, then the mounting function is achieved, but the structure becomes complex and occupies large space
Solution Approach 1:
The conventional mating structure is divided into two independent components: a locking member on the body and a positioning member on the support frame. This segmentation allows each component to be simplified independently while maintaining the overall mounting function, reducing overall structural complexity without compromising reliability
Solution Approach 2:
The essential mounting function is extracted from the complex conventional structure, leaving only the core locking and positioning elements. This extraction removes unnecessary components and simplifies the overall structure while preserving the fundamental mounting capability
2Ease of operation
If conventional mating structures are used to mount the body to the support frame, then the mounting function is achieved, but the operation becomes inconvenient
Solution Approach 1:
The locking member is designed to automatically engage with the positioning member when the body is placed on the support frame, eliminating the need for complex manual adjustment or multiple steps. The structure serves itself by automatically achieving the mounted state through simple placement, greatly improving operational convenience
Solution Approach 2:
Instead of requiring active engagement mechanisms, the design uses passive engagement where the locking member naturally moves into the locked position through gravity or spring force when the body is placed on the support frame. This inverted approach simplifies operation from complex active control to simple passive placement
3Device complexity
If a simple snapping structure is used, then the operation becomes convenient and space is reduced, but the mounting reliability may be compromised
Solution Approach 1:
The locking member and positioning member are designed with asymmetric geometries that ensure unidirectional engagement. The locking member has a specific shape that fits into the positioning member in only one orientation, preventing accidental disengagement while maintaining simple structure. This asymmetric design provides inherent reliability through geometric constraint
Solution Approach 2:
The locking and positioning surfaces incorporate curved or rounded features that guide the engagement process and ensure proper alignment. The curved surfaces allow for self-alignment during placement and provide smooth transition into the locked state, maintaining reliability while simplifying the engagement process

AI summary
A snapping structure is provided, which is configured to detachably mount a body to a support frame. The snapping structure includes a locking member movably disposed on the body and a positioning member disposed on the support frame and mated with the locking member. The locking member is movable to be locked to the positioning member, so as to mount the body to the support frame, or the locking member is movable to be unlocked from the positioning member, so as to separate the body from the support frame.
