Child Safety Seat Socket Sealing for Dust and Hand Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats with front shield types have sockets that are open, leading to dust accumulation and potential safety hazards from accidental hand insertion.
Innovation Solution
A child safety seat with a sealing mechanism featuring a slidably arranged sealing member that seals the mounting opening, using elastic reset members to ensure the fitting is securely connected and can be easily installed or removed, preventing dust ingress and hand insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the socket is opened for easy installation, then the ease of operation is improved, but dust accumulation and safety hazards occur
Solution Approach 1:
The patent applies a flexible sealing member (thin film structure) that covers the mounting opening to prevent dust accumulation and accidental hand insertion while allowing the fitting to be installed and removed. The sealing member acts as a flexible barrier that maintains safety and cleanliness without permanently blocking access.
Solution Approach 2:
The sealing member is designed to be movable rather than fixed, allowing it to be pushed open during installation and automatically return to its closed sealing position afterward. This dynamic behavior enables the system to switch between open (for installation) and closed (for safety and cleanliness) states as needed.
2Object-affected harmful factors
If the sealing member is always closed, then dust accumulation and safety hazards are prevented, but the ease of operation deteriorates
Solution Approach 1:
The sealing member transitions from a static closed state to a dynamic system that can be temporarily opened for installation and automatically returns to closed state. The elastic reset member enables this dynamic behavior, allowing the sealing member to move aside during installation and then return to its sealing position, thus maintaining safety while enabling operation.
Solution Approach 2:
The elastic reset member is pre-loaded to automatically return the sealing member to its closed sealing position after installation. This preliminary action ensures that the sealing member is restored to its safe closed state immediately after the fitting is installed, without requiring manual intervention to close it.
3Reliability
If the connecting member is fixed in the accommodating groove, then the reliability is improved, but the ease of operation worsens
Solution Approach 1:
The connecting member is designed to be movable within the accommodating groove rather than permanently fixed. It can slide along the groove to engage with the fitting for secure connection, and can be pushed to disengage when needed. This dynamic positioning enables both reliable connection and easy disassembly.
Solution Approach 2:
The connection system is divided into separable components: the connecting member with accommodating groove and the fitting with corresponding engaging structure. This segmentation allows the components to be easily assembled and disassembled while maintaining secure connection during use, as each component can be independently positioned and engaged.
