Lateral protecting mechanism and child restraint system therewith
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety seat lateral protecting devices are either non-foldable, occupying excessive space, or foldable but prone to being forgotten in the unfolded state, leading to ineffective protection during emergencies.
Innovation Solution
A lateral protecting mechanism with an automatic unfolding operation, featuring a fixing base, pivoting protecting block, sliding locking component, and operating component, which can be manually controlled to fold or unfold based on demand, ensuring the protecting block is in the correct position for impact reduction without user oversight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lateral protecting device is made non-foldable to ensure it is always in position for protection, then protection reliability is improved, but space occupation increases and it interferes with nearby passengers
Solution Approach 1:
The protecting block is designed to be dynamically adjustable between folded and unfolded states. It includes a pivoting mechanism allowing the protecting block to rotate between a folded position (reducing space occupation) and an unfolded position (providing lateral protection). The system transitions from a static non-foldable design to a dynamic adjustable design, resolving the contradiction between protection reliability and space occupation.
2Volume of moving object
If a lateral protecting device is made foldable to reduce space occupation, then space efficiency is improved, but users may forget to unfold it before traveling, reducing protection reliability
Solution Approach 1:
The system employs a detecting mechanism that automatically monitors the state of the protecting block and provides reminders to users. The detecting mechanism includes sensors that detect whether the protecting block is in the folded or unfolded state, and a reminding mechanism (such as visual or audible alerts) that notifies users if the protecting block is not properly positioned before travel, eliminating the need for user memory and ensuring protection reliability.
Solution Approach 2:
The system incorporates a feedback loop through the detecting mechanism that continuously monitors the protecting block's position and provides real-time information to the user. When the protecting block is in the folded state during travel, the system generates a warning signal, creating a closed-loop feedback system that ensures the protecting block is properly positioned, thereby maintaining protection reliability while preserving space-saving foldability.
3Volume of moving object
If both lateral protecting devices are made foldable to save space, then space efficiency is improved, but users cannot selectively fold one device while keeping the other unfolded according to practical demands
Solution Approach 1:
The system divides the lateral protecting mechanism into independent, separately controllable units. Each protecting block has its own pivoting mechanism, detecting mechanism, and reminding mechanism, allowing each side to be independently folded or unfolded. This segmentation enables selective folding where one protecting block can be folded for space saving while the other remains unfolded for protection, providing adaptability to different practical demands.

AI summary
A lateral protecting mechanism includes a fixing base, a protecting block, a locking component, a driving component and an operating component. The fixing base is fixedly disposed on a lateral portion of a child carrier. The protecting block includes a pivoting shaft and is pivotally disposed on the fixing base by the pivoting shaft. The locking component is slidably disposed inside the fixing base. The driving component is disposed inside the fixing base. The operating component is coupled to the driving component. The operating component drives the driving component to drive the locking component to protrude out of the fixing base to abut against the protecting block for restraining a pivoting movement of the protecting block when the operating component is operated.
