Child Seat Carrying Handle Unlocking for Easy Uncoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child seats lack enhanced operability in uncoupling from supporting devices, requiring manual operation of release portions like push buttons.
Innovation Solution
A child seat design featuring a movable and rotatable carrying handle that functions as an operating portion to transfer the coupling portion between locking and unlocking configurations, utilizing a guiding mechanism and blocking mechanism to facilitate tool-free uncoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a push button or release portion is used for uncoupling, then the coupling is secure, but the operation becomes complex and less convenient
Solution Approach 1:
The carrying handle is merged with the operating portion for the coupling mechanism. The handle itself becomes the actuating element that transfers movement to the coupling portion, eliminating the need for separate push buttons or release mechanisms. This integration simplifies the overall device structure while maintaining secure coupling functionality.
Solution Approach 2:
The carrying handle serves multiple functions: it is used for carrying the child seat and simultaneously acts as the operating portion for unlocking and uncoupling the seat from the supporting device. This multi-functionality reduces the number of separate components needed and simplifies the user interface.
2Ease of operation
If the coupling mechanism is simplified for easy uncoupling, then operability improves, but the security and reliability of coupling may be compromised
Solution Approach 1:
The coupling mechanism uses dynamic elements including a movable coupling portion that can transition between locked and unlocked states, and a blocking mechanism that dynamically engages or disengages based on the handle position. The blocking mechanism includes a blocking element that can be moved to prevent accidental uncoupling, providing security while allowing intentional uncoupling through handle movement.
3Ease of operation
If the carrying handle is made movable and rotatable, then operability is enhanced, but the device complexity increases
Solution Approach 1:
The connecting portion between the carrying handle and seat body is segmented into distinct functional elements: a guiding mechanism with guiding path, a blocking mechanism with blocking element, and the coupling portion. This segmentation allows each element to perform its specific function independently while working together as a coordinated system, making the complexity manageable and the operation intuitive.

AI summary
The child seat comprises a seat body (10), a carrying handle (20) configured to be grasped by a user for carrying the child seat (1), and a coupling portion (100) for coupling said child seat (1) on a supporting device (2), for example on a car seat base or to a child carrier frame, such as a stroller frame. The coupling portion (100) is configured transferable between a locking configuration in which the coupling portion (100) is locked to the supporting device (2) and an unlocking configuration in which it is unlocked and removable from the supporting device (2). The coupling portion (100) is transferable into the unlocking configuration by moving, for example sliding or shifting, the carrying handle (20) relative to the seat body (10) along a guiding path from a locking position to an unlocking position.
