Pivotable Belt Clamp Anchor for Vehicle Child Seat Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child restraints for vehicles lack an efficient mechanism to securely anchor the seat-support base to the passenger seat using the vehicle's seat belt, which can lead to instability and inadequate safety during transport.
Innovation Solution
A child restraint system featuring a pivotable belt clamp and seat mount that allows the vehicle seat belt to be securely anchored to the seat-support base, providing a stationary position for the juvenile seat, with a hidden top-end clamp anchor for easy removal and reinstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pivotable belt clamp mechanism is used to securely anchor the seat-support base, then the reliability and stability of the child restraint system is improved, but the device complexity increases due to the additional pivotable components and hidden clamp anchor mechanisms
Solution Approach 1:
The top-end clamp anchor is nested within the pivotable belt clamp assembly, hidden from view during normal operation. The anchor mechanism is contained within the clamp structure, allowing the belt clamp to serve dual functions: visible anchoring operation and hidden secure locking, thereby improving reliability without proportionally increasing external complexity
Solution Approach 2:
The belt clamp is designed to be pivotable rather than fixed, allowing it to move between an open position for installation and a closed position for secure anchoring. This dynamic mechanism enables the system to transition between different states, improving both reliability during installation and ease of operation
2Ease of operation
If the top-end clamp anchor is hidden from view under the seat mount, then the ease of operation is improved by preventing accidental activation, but the ease of repair and detection of anchor status becomes more difficult
Solution Approach 1:
The patent employs visual indicators (such as colored elements or visible markers) that change or become visible to indicate the anchoring status of the hidden clamp anchor. This allows the anchor status to be detected without exposing the entire anchor mechanism, maintaining protection from accidental activation while enabling status verification
Solution Approach 2:
A visual indicator or marker serves as an intermediary between the hidden clamp anchor and the observer. This intermediary provides information about the anchor's status without requiring direct visibility of the anchor itself, resolving the contradiction between hiding the anchor and enabling status detection

AI summary
A child restraint includes a juvenile seat and a base for supporting the juvenile seat. The base is adapted to be anchored to lie in a stationary position on a passenger seat of a vehicle to support the juvenile seat in the vehicle.
