Infant Car Seat Obstructing Element for Secure Docking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car seats may be improperly secured to vehicle docking devices, posing a safety risk for infants in the event of a collision or sudden stop, as parents and caregivers often fail to ensure correct installation.
Innovation Solution
A car seat system with an obstructing element that prevents seating unless properly secured to a docking device, utilizing a rotation control mechanism synchronized with a seat securing mechanism to maintain the obstructing element in a protruding position when the seat is not correctly installed, and allowing seating only when securely attached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an obstructing element is added to prevent improper seating, then safety is improved, but device complexity increases
Solution Approach 1:
The obstructing element is nested within the seating space, allowing it to protrude when needed to prevent improper seating while remaining concealed when retracted. This nesting approach adds the safety function without significantly increasing external device complexity or altering the overall seat structure.
Solution Approach 2:
The obstructing element is designed to be movable between an extended position (when the seat is improperly secured) and a retracted position (when properly secured). This dynamic capability allows the system to adapt its behavior based on the securing state, providing safety only when conditions are met without requiring a permanently complex structure.
2Reliability
If a rotation control mechanism synchronized with the securing mechanism is implemented, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The rotation control mechanism is merged with the existing seat securing mechanism, so that a single user action (securing the seat) simultaneously performs both the securing function and the obstruction control function. This integration ensures reliability by linking the two functions while minimizing the impact on ease of operation, as users perform only the necessary securing action.
Solution Approach 2:
The system uses the motion from the user's securing action to automatically control the obstructing element through the rotation control mechanism. The user does not need to separately operate the obstructing element; it is self-controlled by the securing mechanism's movement, maintaining ease of operation while ensuring reliability.
3Reliability
If the obstructing element protrudes at least 25 millimeters into the seating space, then safety is improved, but comfort deteriorates
Solution Approach 1:
The obstructing element dynamically changes its position based on the securing state: it protrudes 25mm or more into the seating space only when the seat is improperly secured to prevent use, and retracts completely when properly secured to eliminate any comfort impact. This dynamic behavior ensures safety is maintained without permanent comfort degradation.
Solution Approach 2:
The obstructing element provides preliminary anti-action by preventing improper seating through its protruding position before any harmful event could occur. By blocking improper use in advance and retracting when proper use is confirmed, it eliminates the need for continuous obstruction, thus maintaining comfort while ensuring safety.

AI summary
A car seat comprising a seat shell formed around at least part of a seating space, a seat securing mechanism adapted to secure the seat shell to the docking device in a secure state and release the seat shell from the docking device in a release state, and a rotation control mechanism mechanically synchronized with the seat securing mechanism and to an obstructing element. The rotation control mechanism prevents rotating the obstructing element between an obstructing state and a non-obstructing state when the seat securing mechanism is not in the secure state. In the obstructing state the obstructing element protrudes into the seating space for obstructing seating of an infant and in the non-obstructing state the obstructing element is angled towards a surface of the seat shell.
