Stroller Front Guard Latch for Compact Folding and Easy Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child stroller apparatuses require separate detachment and storage of the front guard, making them inconvenient to use.
Innovation Solution
A child stroller apparatus with a locking mechanism that allows the front guard to be pivotally connected and locked to the handle frame, enabling easy folding and unfolding without separate detachment, using a release actuator to unlock the front guard for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the front guard is detachably attached to the stroller frame, then the stroller can be folded to a compact size, but the operation becomes inconvenient due to separate detachment and storage requirements
Solution Approach 1:
The front guard is merged with the stroller frame through a locking mechanism that integrates both components. The latch assembly combines the locking and unlocking functions within the same structural unit, eliminating the need for separate detachment and storage operations while maintaining compact folding capability.
2Ease of operation
If the front guard is permanently attached to the stroller frame, then operation convenience is improved, but the folding capability is compromised
Solution Approach 1:
The connection between the front guard and stroller frame is made dynamic through the locking mechanism. The latch assembly can transition between locked and unlocked states, allowing the front guard to be securely attached during use and easily detached during folding, providing both operational convenience and compact storage.
3Ease of operation
If a locking mechanism is added to connect the front guard and handle frame, then operational convenience is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: the latch assembly for locking/unlocking, the release actuator for triggering the latch, and the coupling parts for connection. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity and ease of manufacturing.

AI summary
A child stroller apparatus includes a standing frame, a handle frame pivotally coupled to the standing frame and having a first coupling part, a front guard having a second coupling part pivotally connected with the first coupling part, and a locking mechanism including a front guard latch. The handle frame is rotatable for folding and unfolding the child stroller apparatus. The front guard is positionable in a deployed configuration while the child stroller apparatus is in an unfolded state. The front guard latch is movable between a locking position where it is engaged with the first and second coupling parts so that the front guard is locked to the handle frame in the deployed configuration, and an unlocking position where the front guard latch is disengaged from one of the first and second coupling parts for rotation of the front guard relative to the handle frame and the standing frame.
