Child Restraint Seat Locking Mechanism for Single-Handle Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child restraints require multiple complex attachment and release mechanisms for secure and convenient detachment from vehicle restraint bases and strollers, leading to counter-intuitive operation.
Innovation Solution
A child restraint seat with a simplified locking mechanism featuring a latch base, rotatable latching components, and a releasing handle connected via cables, allowing simultaneous engagement and disengagement from external structural units like strollers or car restraint bases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple attachment mechanisms and release actuators are used on the restraint seat, then the connection between the restraint seat and external structural units becomes more reliable, but the device complexity increases and the ease of operation deteriorates
Solution Approach 1:
The patent combines multiple latching components (first latching component for stroller attachment and second latching component for base attachment) into a single integrated locking mechanism. Both latching components are actuated by a single releasing handle that simultaneously releases both attachments, merging multiple functions into one unified system that reduces complexity while maintaining reliable connections to both strollers and bases.
2Adaptability or versatility
If multiple release actuators are used for different attachment points, then each attachment can be released independently, but the ease of operation deteriorates due to counter-intuitive operation
Solution Approach 1:
The patent employs a single releasing handle that simultaneously actuates both the first latching component (for stroller attachment) and the second latching component (for base attachment). This unified actuation mechanism allows the user to release both attachments with one intuitive action, eliminating the confusion of operating multiple separate actuators while maintaining the versatility to attach to different external structural units.
3Ease of operation
If a simplified locking mechanism with a single releasing handle is used, then the ease of operation improves, but the device complexity reduction must maintain connection reliability
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a latch base, a first latching component with an engaging portion for stroller attachment, and a second latching component with an engaging portion for base attachment. Each latching component has its own engaging portion that can independently engage with corresponding external structural units, ensuring reliable connections while being controlled by a single releasing handle for simplified operation.

AI summary
A child restraint seat includes a seat unit, a locking mechanism and a releasing handle. The locking mechanism is disposed on the seat unit and adapted to fix the seat unit onto a first external structural unit. The locking mechanism includes a latch base disposed on the seat unit, a first latching component movably disposed on the latch base, and a lock releasing component connected to the first latching component. The first latching component is adapted to move relative to a first constraining component of the first external structural unit for switching between a closed position and an open position. The releasing handle is disposed on the seat unit and connected to the lock releasing component, the releasing handle is utilized to drive the lock releasing component to move the first latching component from the closed position to the open position.
