Child Seat Impact Shield Locking to Prevent Misattachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Child seats with impact shields often face issues with improper use and misuse, leading to safety concerns due to the risk of incorrect or incomplete attachment, which can compromise the protection of children during collisions.
Innovation Solution
The child seat is designed to prevent the complete removal or partial disassembly of the impact shield in specific configurations and states of use, ensuring it remains attached to the main body, thereby enhancing safety by restricting misuse and ensuring the impact shield is always present when required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the impact shield is made detachable for ease of installation and removal, then the ease of operation is improved, but the reliability deteriorates due to risk of improper attachment or complete removal
Solution Approach 1:
The impact shield attachment system transitions from a static fixed or removable state to a dynamic state where the shield can be installed and removed only under specific conditions. The system adapts its locking behavior based on the detected configuration state, allowing easy installation when appropriate but preventing removal when the child seat is in an unsafe configuration.
Solution Approach 2:
The patent changes the parameter of attachment state from a simple binary (attached/not attached) to a conditional state based on configuration parameters. The attachment mechanism responds to changes in configuration parameters (such as harness position, seat angle, or other safety-critical settings) by automatically adjusting whether the impact shield can be detached, thereby maintaining reliability while preserving operational flexibility when safe.
2Adaptability or versatility
If the impact shield can be completely removed for storage or alternative use, then the adaptability is improved, but the safety deteriorates due to risk of use without protection
Solution Approach 1:
The system takes preliminary anti-action by preventing the removal of the impact shield before a safety check is performed. The attachment mechanism is designed to block detachment attempts when the child seat configuration indicates that the shield is needed for safety, thereby preventing the harmful state of traveling without impact protection before it can occur.
Solution Approach 2:
The patent introduces an intermediary control mechanism between the user's intent to remove the shield and the actual physical detachment. This intermediary system evaluates the current configuration state and mediates the attachment status, allowing removal only when the evaluation confirms it is safe to do so, thus preventing direct unauthorized removal that would compromise safety.
3Reliability
If locking mechanisms are added to prevent unauthorized removal, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the locking mechanism with the existing attachment structure of the impact shield. Rather than adding separate complex locking devices, the design integrates the conditional locking functionality into the attachment points and connecting elements already present in the child seat system, thereby improving reliability while minimizing the increase in device complexity.

AI summary
The invention relates to a child seat for attaching to a motor vehicle seat, comprising an impact shield, wherein the impact shield is prevented from being dismantled from a main body in at least a first configuration and/or in at least a first state of use of the child seat and/or is prevented from being partially or at least fully mounted on a/the main body in at least a second configuration and/or in at least a second state of use of the child seat, and/or wherein possibilities for configuring and/or installing the child seat are dependent on the fastened state of the impact shield.
