Solution Overview

Problem

Unsecured heavy objects in a vehicle cabin pose a safety risk to passengers and drivers due to potential movement during acceleration, braking, or turns, which can lead to injuries or accidents.

Innovation Solution

A vehicle cabin safety system that uses cameras and sensors to detect objects within the cabin, determine their features and movement, and output a warning signal if the danger level meets certain criteria, thereby preventing potential hazards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If heavy objects are stored in the vehicle cabin, then the vehicle's cargo capacity is improved, but the safety of passengers and driver deteriorates due to potential movement during acceleration or braking

Engineering Contradiction:
Improvecargo capacityVSAvoidsafety risk from moving objects
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection of objects in the cabin before dangerous movement occurs. Sensors continuously monitor the cabin environment to identify heavy objects that could become hazardous during acceleration or braking, allowing the system to alert passengers in advance to secure the objects.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where sensor data about object position and vehicle motion is continuously processed, and warning signals are generated when objects are detected in dangerous positions. This closed-loop monitoring enables real-time safety alerts to be issued to passengers.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If objects are placed in the vehicle cabin, then the utility of the vehicle is improved, but the driver's view and maneuverability deteriorate due to potential blockage

Engineering Contradiction:
Improvevehicle utilityVSAvoiddriver's view blockage
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system proactively identifies objects that could block the driver's view before the vehicle is driven or during initial driving phases. By detecting objects in the driver's field of view early, the system can issue warnings to passengers to relocate items that would interfere with safe operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sensor system acts as an intermediary between objects in the cabin and the driver, providing indirect information about potential view blockages. Rather than directly preventing object placement, the system mediates safety by alerting the driver and passengers to reposition objects that could interfere with driving.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a warning system is implemented to detect dangerous objects, then the safety of passengers is improved, but the device complexity increases due to additional sensors and processing systems

Engineering Contradiction:
Improvepassenger safetyVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system uses multi-functional sensors that can detect both the presence of objects and their movement characteristics. The same sensor array serves multiple purposes: identifying object location, estimating mass based on motion response, and monitoring cabin occupancy, thereby reducing the need for separate specialized sensors for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system leverages the objects' own physical properties and responses to vehicle motion to determine their mass and danger level. By observing how objects move during vehicle acceleration or braking, the system self-determines object characteristics without requiring additional active sensors or complex measurement equipment.

Inventive Principle:
Principle #25Self-service

AI summary

This invention relates to vehicle cabin safety and in particular to the detection of objects and their movements in a vehicle cabin. Based on one or more images showing an interior of the vehicle cabin, at least one object in the vehicle cabin is determined. A number of features of the at least one object and a danger level for the at least one object is determined based on the number of features. In response to determining that the danger level meets a given criteria, a warning signal is outputted.
