Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a driver monitoring system is implemented to detect physiological states, then driving safety is improved, but device complexity increases

Engineering Contradiction:
Improvedriving safetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The camera module serves multiple functions: capturing driver images for physiological state detection, monitoring driver behavior, and potentially recording driving conditions. This multi-functionality reduces the need for separate dedicated sensors for each monitoring task, thereby improving safety while limiting the increase in system complexity.

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

Solution Approach 2:

The system replaces complex mechanical physiological sensors with optical imaging technology. By using a camera to capture images and analyze physiological states through image processing algorithms, the system achieves accurate detection without requiring intrusive mechanical sensors that would increase device complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If an image capturing module with multiple lenses is used to detect driver physiological states, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvephysiological state detection accuracyVSAvoidlens group complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple lens groups are combined into a single integrated camera module. The first lens group captures images through a first aperture while the second lens group captures images through a second aperture, allowing simultaneous multi-angle or multi-focus imaging within one compact unit, thereby improving detection precision without proportionally increasing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system adds dimensional complexity by incorporating multiple lens groups with different optical paths and apertures. This enables capture of images from different perspectives or focal depths, providing richer data for physiological state analysis while maintaining a compact form factor through sophisticated optical design.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A movable carrier auxiliary system includes a driver state detecting device and a warning device. The driver state detecting device includes a physiological state detecting module, a storage module, and an operation module. The physiological state detecting module is adapted to detect a physiological state of a driver. The storage module is disposed in a movable carrier and stores an allowable parameter corresponding to the at least one physiological state. The operation module is disposed in the movable carrier and is electrically connected to the physiological state detecting module and the storage module to detect whether the at least one physiological state of the driver exceeds the allowable parameter or not, and to correspondingly generate a detection signal. The warning device generate a warning message when the detection signal that the at least one physiological state of the driver exceeds the allowable parameter is received.
