Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biological detectors (sensing electrodes) are installed to monitor driver's physiological state, then driver discomfort detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the essential safety monitoring function from complex biological detection systems. Instead of using multiple sensing electrodes to monitor various physiological parameters, the invention focuses on a single critical function: detecting whether the driver's hand is placed on the steering wheel. This simplifies the system structure while maintaining effective safety monitoring capability.
Solution Approach 2:
The sensing unit on the steering wheel serves multiple functions: it detects hand presence, determines driver attention state, and triggers appropriate warnings. This multi-functional design replaces the need for separate biological detectors, reducing system complexity while achieving comprehensive safety monitoring.
2Measurement precision
If multiple sensing units are installed on the steering member to improve detection accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The steering wheel is divided into multiple sensing zones with sensing units distributed at different positions. Each sensing unit independently detects hand presence in its specific zone, and the processing unit integrates these segmented detection results to determine overall hand presence status, improving detection accuracy without requiring a single complex sensing system.
3Speed
If real-time monitoring and warning systems are implemented, then response speed to dangerous situations is improved, but energy consumption increases
Solution Approach 1:
The processing unit performs periodic detection of sensing signals at predetermined intervals rather than continuous monitoring. This periodic action enables real-time safety monitoring with fast warning response while significantly reducing energy consumption compared to continuous real-time monitoring systems.

AI summary
A safety monitoring apparatus and method thereof for human-driven vehicle are provided. The safety monitoring apparatus includes a sensing unit, a processing unit, and a warning unit. The sensing unit and the warning unit are electrically connected to the processing unit, respectively. The sensing unit is arranged on a steering member of the human-driven vehicle and is used for sensing whether the steering member is in contact with a hand of a driver and generating a sensing signal accordingly. The processing unit determines whether the hand of the driver is placed on the steering member. The warning unit is used for generating a safety warning message. When the processing unit determines that the hand of the driver has not been placed on the steering member according to the sensing signal, the processing unit drives the warning unit to generate the safety warning message to warn the driver.
