Multi-Sensor Child Presence Detection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety systems for vehicles are designed for a single infant or child, making them costly and complex to install and use for multiple children, and do not effectively alert drivers to the presence of children left in unattended vehicles, leading to potential heat stroke injuries or deaths.
Innovation Solution
A car safety seat alarm system with multiple weight sensor pads that can be installed in various car seats, detecting the presence of children and triggering an alarm and lighting when the vehicle door is opened, allowing for easy installation and use with multiple seats and vehicle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate child safety systems are purchased for multiple children, then child safety coverage is improved, but system complexity and installation difficulty increase
Solution Approach 1:
The patent combines multiple child safety monitoring functions into a single integrated alarm system that can detect and monitor multiple children simultaneously. The system uses a centralized control unit with multiple sensors to replace what would traditionally require multiple separate safety systems, thereby reducing overall system complexity while maintaining comprehensive safety coverage.
Solution Approach 2:
The alarm system is designed as a universal multi-functional device that can monitor multiple children across different seats simultaneously. The system performs multiple functions including weight detection, alarm activation, and visual signaling all through a single integrated platform, eliminating the need for multiple specialized devices.
2Reliability
If multiple separate child safety systems are installed for multiple children, then monitoring coverage is improved, but installation ease deteriorates
Solution Approach 1:
The patent integrates multiple monitoring functions into a single alarm system that can be installed once to cover multiple children. The centralized design with multiple sensors allows comprehensive monitoring coverage without requiring separate installations for each child, significantly improving installation ease while maintaining full monitoring coverage.
3Ease of operation
If a single child safety system is used, then installation simplicity is improved, but monitoring capability for multiple children deteriorates
Solution Approach 1:
The alarm system is designed as a universal multi-functional device capable of monitoring multiple children simultaneously through its multiple sensors and integrated control unit. This single system provides comprehensive monitoring capability across all seats while maintaining installation simplicity through its unified design.
4Reliability
If traditional alarm systems are used, then alert function is improved, but driver awareness effectiveness deteriorates
Solution Approach 1:
The patent employs different types of alerts tailored to specific situations and locations within the vehicle. Visual alerts are positioned in the driver's field of view, while audible alerts provide additional notification. This localized and differentiated alert approach ensures that drivers receive effective notification about children left in vehicles, directly addressing the driver awareness effectiveness issue.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a cost-effective and easy-to-install solution for monitoring multiple children, reducing the risk of children being left unattended and minimizing the risk of heat stroke injuries by ensuring drivers are alerted to their presence when leaving the vehicle.
Implementation Method 1
Each of the plurality of weight sensor pads can detect the presence or absence of a child on a seat by sensing the weight applied on the seat
