Child Vehicle Seat Chassis Mounting Detection and Alarm System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child vehicle seats lack a simple and reliable method to verify if they are correctly secured in a vehicle, posing a safety risk if the seat and child can freely move during accidents due to incorrect mounting.
Innovation Solution
The child vehicle seat features a chassis with detectors and indicators to ensure correct mounting and connection, including isofix connectors and a support leg, which deliver alarm signals or positive indications to confirm secure attachment, and a check button to verify the seat's connection to the chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seat is undetachably connected to the chassis, then the connection reliability is improved, but the adaptability deteriorates
Solution Approach 1:
The child vehicle seat system is divided into separate functional modules: the chassis with mounting elements, the seat unit, and the detector system. This segmentation allows the seat to be detachably connected to the chassis while maintaining reliable mounting to the vehicle through the chassis's connectors, thus achieving both adaptability and reliability.
2Reliability
If detectors and indicators are added to verify correct mounting, then the safety is improved, but the device complexity increases
Solution Approach 1:
The chassis is equipped with detectors that automatically verify whether the mounting elements are correctly mounted in the vehicle, and indicators provide visual feedback to the user about the mounting status. This feedback mechanism ensures safety by confirming correct installation without requiring complex manual verification procedures.
Solution Approach 2:
The detector system automatically performs the verification function without requiring user intervention or complex external equipment. The system self-activates when the chassis is mounted in the vehicle and provides automatic indication of correct mounting, simplifying the overall device complexity while maintaining high safety standards.
3Reliability
If an alarm signal is delivered when the chassis is not correctly secured, then the safety is improved, but the ease of operation deteriorates
Solution Approach 1:
The alarm signal provides clear feedback to the user about incorrect mounting, eliminating ambiguity. Combined with the visual indicators showing mounting status, the system guides users through the correct installation process, making operation easier despite the added safety checks.

AI summary
A child vehicle seat comprises a seat, a chassis, at least one mounting element for securing the chassis in a vehicle, as well as at least one detector for detecting whether the mounting element is correctly mounted in the vehicle. The chassis is further provided with at least one indicator for indicating whether the chassis is correctly secured in the vehicle. The seat is detachably connectable to the chassis. The chassis is provided with at least one detector for detecting whether the seat is correctly connected to the chassis, whilst an alarm signal is delivered by the indicator in use if the chassis is not correctly secured in the vehicle whilst the seat is correctly connected to the chassis.
