Vehicle Seat Pressure Sensor Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat adjustment systems fail to provide personalized comfort for occupants, leading to discomfort during long journeys as they do not account for individual characteristics and posture.
Innovation Solution
A method and system that captures and evaluates loading data, such as pressure distribution, to create a control dataset for periodic seat adjustments, using a pressure sensor module and seat control device to adapt seat positions based on individual characteristics and posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If seat position is changed by activating actuator motors, then seating discomfort is reduced for some occupants, but the solution is not personalized and may be disagreeable for other people with different body characteristics
Solution Approach 1:
The system uses pressure sensors to continuously monitor the pressure distribution on the seat, creating feedback about the occupant's body characteristics and posture. This feedback is processed to automatically adjust seat parameters (position, heating, ventilation, lumbar support) to achieve optimal comfort for each individual occupant, resolving the contradiction between general comfort improvement and personalization.
Solution Approach 2:
The seat system performs self-adjustment based on the pressure distribution data it collects. The control unit automatically modifies seat parameters without requiring manual input from the occupant, allowing the seat to serve itself in adapting to different occupants' needs, thus achieving personalization without adding complex user interaction mechanisms.
2Adaptability or versatility
If pressure sensors are installed to capture loading data for personalized adjustment, then personalization capability is improved, but device complexity and cost increase
Solution Approach 1:
The pressure sensor system serves multiple functions: it detects occupant presence, determines body type, monitors posture, and tracks pressure distribution over time. By making the sensor system multi-functional, the patent achieves high personalization capability without proportionally increasing complexity, as the same hardware infrastructure supports multiple adjustment parameters and comfort functions.
