Smart Multi-Contoured Seat Support System for Driver Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle seat systems require independent adjustment of multiple features, leading to complexity and driver distraction, as each feature must be adjusted manually, increasing the burden on users and complicating the adjustment process.
Innovation Solution
A smart multi-contoured seat support system that adjusts multiple seat support features simultaneously based on a user-selected mode type, using a controller to detect the mode and adjust the features pneumatically or mechanically, with sensors monitoring pressure and force to determine adjustments, and storing the last selected mode for efficient restart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple seat support features are adjusted independently, then each feature can be precisely controlled, but the system complexity increases and driver distraction increases
Solution Approach 1:
The patent combines multiple independent seat adjustment features into integrated adjustment modes. Instead of controlling each feature (lumbar support, seat cushion angle, headrest position, etc.) separately, the system merges them into preset modes that adjust multiple features simultaneously based on driver detection data, thereby reducing operational complexity while maintaining control precision.
Solution Approach 2:
The control system is designed to perform multiple functions: it detects driver posture, determines appropriate adjustment modes, controls multiple seat features, and provides user feedback. This multi-functional approach eliminates the need for separate control mechanisms for each seat feature, reducing overall system complexity while preserving precise adjustment capabilities.
2Ease of operation
If multiple seat support features are adjusted independently, then each feature can be precisely controlled, but driver distraction increases
Solution Approach 1:
The seat adjustment system operates autonomously by detecting driver posture through sensors, automatically determining the appropriate adjustment mode, and executing the necessary feature adjustments without requiring continuous driver input. This self-service mechanism eliminates driver distraction while maintaining precise control over seat features.
Solution Approach 2:
The system performs preliminary detection of driver posture and pre-determines the appropriate adjustment mode before executing seat feature adjustments. This preliminary action allows the system to prepare adjustment commands in advance, reducing the time the driver needs to interact with controls and minimizing distraction during vehicle operation.
3Adaptability or versatility
If 30 or more feature adjustments are provided, then seat support capability is enhanced, but the system becomes more complex than convenient
Solution Approach 1:
The patent segments the 30+ seat adjustment features into logical groups that can be controlled through a limited number of adjustment modes. Each mode targets specific groups of features (e.g., lumbar support group, seat cushion group, headrest group) that work together to achieve particular support objectives, making the complex system manageable through intuitive mode selection rather than individual feature control.
Solution Approach 2:
The system changes control parameters from individual feature settings to mode-based adjustments. Instead of requiring users to manipulate 30+ individual parameters, the system transforms them into a smaller set of mode parameters that automatically coordinate multiple features, thereby maintaining high adaptability while improving system convenience and ease of use.

Function Achieved in This Case
The system reduces driver distraction by allowing simultaneous adjustment of multiple features, enhances user convenience with customizable support profiles, and simplifies the adjustment process by eliminating the need for individual feature control, while reducing system complexity and manufacturing costs.

AI summary
A method of adjusting a vehicle seat support system is provided. In particular, the method includes receiving a user selection at an input device and detecting a mode type associated with the user selection. A plurality of seat support features disposed within a vehicle seat are then adjusted toward a support characteristic that corresponds to the detected mode type.
