Posture Control Apparatus for Driver Seat Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often fail to maintain a comfortable and healthy posture while driving due to mismatched vehicle equipment and varying travel environments, leading to potential health issues and reduced visibility.
Innovation Solution
A posture control apparatus that adjusts seat, mirror, and steering wheel positions based on driver-specific data such as sex, stature, weight, and body type, incorporating travel environment and health information to optimize driver posture for comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed equipment and parts are installed in the vehicle, then the device complexity is reduced, but the adaptability to different driver body sizes and postures deteriorates
Solution Approach 1:
The patent applies dynamics by making the seat position adjustable rather than fixed. The seat can dynamically change its position forward or backward based on the driver's body characteristics (height, weight) detected by sensors, allowing the same fixed-installation equipment to adapt to different drivers without increasing installation complexity.
Solution Approach 2:
The system changes the position parameter of the seat based on driver parameters (height, weight, body type). By adjusting the seat position parameter dynamically, the system achieves adaptability to different drivers while maintaining simple fixed installation of the equipment itself.
2Ease of operation
If the seat is adjusted to be up close to the steering wheel, then the ease of operation is improved, but the driver health deteriorates due to rigid posture
Solution Approach 1:
The seat position is dynamically adjusted based on the driver's body characteristics rather than being fixed in a rigid position. This dynamic adjustment ensures the seat is optimally positioned for each driver's ergonomics, maintaining ease of operation while preventing health issues from poor posture.
Solution Approach 2:
The system uses sensors to detect driver body characteristics and provides feedback to automatically adjust the seat position. This closed-loop feedback ensures the seat is positioned correctly for each driver, preventing both overly close positions that cause health issues and overly distant positions that reduce operability.
3Device complexity
If manual adjustment of seat and mirrors is required, then the device complexity is reduced, but the time required for driver preparation increases
Solution Approach 1:
The system performs self-service by automatically detecting driver body characteristics and adjusting the seat position without manual intervention. The driver simply enters the vehicle, and the system autonomously configures the optimal seat position, eliminating the time-consuming manual adjustment process while using simple sensors and actuators.
Solution Approach 2:
The seat position is adjusted in advance automatically when the driver enters the vehicle, before the driver begins driving. This preliminary automatic adjustment eliminates the need for manual adjustment during the driving preparation phase, saving time without requiring complex adjustment mechanisms.
4Manufacturing precision
If seat position is fixed upon installation, then the manufacturing precision requirement is reduced, but the suitability for individual driver needs deteriorates
Solution Approach 1:
The seat position is made dynamic and adjustable after installation rather than being fixed during manufacturing. This allows the seat to be repositioned for each driver based on their body characteristics, achieving high suitability for individual drivers without requiring high manufacturing precision for each specific configuration.
Solution Approach 2:
The seat system is designed to be universal, accommodating multiple driver body types through automatic adjustment. A single seat installation can serve drivers of various heights, weights, and body types by dynamically adjusting its position, eliminating the need for high manufacturing precision tailored to each individual driver.
Data Source
AI summary
A posture control apparatus is provided. More specifically, a memory stores positional information of a seat corresponding to a sex, a stature, a sitting stature and a body type of a driver. An information collector receives the sex, the stature, the sitting stature and a weight of the driver and a sitting stature section determinator determines a sitting stature section of the driver based on the received stature and sitting stature of the driver. A Body Mass Index section determinator determines a body type section of the driver based on the received sex, stature, and weight of the driver. A controller then determines a position of the seat corresponding to the sex, the stature, the sitting stature section and the body type section of the driver based on the positional information of the seat stored in the memory.
