Vehicle Cockpit Auto-Adjustment Using Full Driver Anthropometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for adjusting a vehicle cockpit based on driver anthropometry are inadequate, as they rely solely on height measurements, failing to account for variations in torso, leg, neck, and arm lengths, leading to uncertain seating positions and comfort issues.
Innovation Solution
A method and system that utilizes anthropometric data, including limb lengths and joint positions, to calculate an ergonomic position for the driver, adjusting seat, steering wheel, and rear-view mirrors using actuators, with sensors detecting driver features and preferences to achieve optimal cockpit configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If only driver height is measured to calculate comfort position, then the system is simple to implement, but the seating position accuracy becomes uncertain
Solution Approach 1:
The patent segments the anthropometric measurement into multiple independent parameters (height, torso length, leg length, arm length, neck length) rather than relying on a single height measurement. Each parameter is measured separately to provide comprehensive data for accurate seat positioning calculation.
Solution Approach 2:
The patent transitions from one-dimensional height measurement to multi-dimensional anthropometric assessment by incorporating additional body dimension measurements (torso, legs, arms, neck). This dimensional expansion enables precise calculation of ergonomic seating position that accounts for individual body proportions.
2Measurement precision
If comprehensive anthropometric data collection is implemented, then seating position accuracy is improved, but the system complexity increases
Solution Approach 1:
The system automatically performs all measurements and calculations without requiring manual input from the driver. Sensors autonomously detect anthropometric parameters, and the control unit automatically processes this data to determine optimal seating position, eliminating the need for manual measurement tools or driver intervention.
Solution Approach 2:
The patent replaces manual measurement methods with automated sensor-based detection systems. Optical sensors, capacitive sensors, or other detection devices automatically measure body dimensions, substituting mechanical measurement tools and manual procedures with electronic sensing and automated processing.
3Device complexity
If manual adjustment by driver is required, then system simplicity is maintained, but adjustment time increases
Solution Approach 1:
The system performs preliminary automatic adjustment of the seat to the calculated ergonomic position before the driver begins driving. This preliminary positioning eliminates the need for subsequent manual adjustments by the driver, saving time and ensuring optimal positioning from the start.
Solution Approach 2:
The seat adjustment system operates autonomously without requiring driver intervention. The control unit automatically controls the seat positioning mechanism based on measured anthropometric data, making the system self-serving and eliminating manual adjustment time.
4Loss of time
If automatic seat adjustment is implemented, then adjustment time is reduced, but the number of components increases
Solution Approach 1:
The control unit serves multiple functions: it processes anthropometric measurement data, calculates ergonomic seating position, and controls seat positioning mechanisms. This multi-functionality consolidates what could be separate components into a single integrated control system, reducing overall component count despite the automated capabilities.
