Seat Motion Sensing With Malfunction-Aware Function Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat experience systems primarily focus on evaluating the driver's sitting posture without encouraging occupant motivation and do not effectively manage power consumption or provide secure operation notifications.
Innovation Solution
A seat experience system comprising a seat with integrated sensors and a controller that detects occupant motion, provides secure operation notifications, and reduces power consumption by limiting functions if malfunctions are detected, allowing for operable objects on a terminal to be controlled based on the occupant's posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the seat experience system continuously monitors sensor data and provides full functionality, then occupant engagement and system utility are improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts its operational state based on sensor data quality. When sensors function normally, the system provides full functionality including games and posture evaluation. When malfunctions are detected, the system transitions to a limited functionality state, dynamically adapting to current conditions to balance engagement and power consumption.
Solution Approach 2:
The system changes operational parameters (functionality level) based on sensor status. By monitoring sensor output validity and changing the system state between full-function and limited-function modes, the system optimizes power consumption while maintaining appropriate occupant engagement levels.
2Adaptability or versatility
If the seat experience system provides comprehensive functionality without malfunction detection, then system capability is improved, but system reliability and occupant security decrease
Solution Approach 1:
The system implements continuous feedback monitoring of sensor data to detect malfunctions. By analyzing sensor output patterns and identifying abnormal readings, the system can reliably detect sensor failures and transition to limited functionality, ensuring occupant safety while maintaining system capability when operating normally.
Solution Approach 2:
The system prepares for potential malfunctions by implementing preemptive malfunction detection mechanisms. Before a malfunction can cause safety issues, the system detects abnormal sensor behavior and proactively limits functionality, cushioning against potential reliability problems.
3Reliability
If malfunction detection and notification features are added, then system reliability is improved, but device complexity increases
Solution Approach 1:
The system performs self-diagnosis by monitoring its own sensor outputs. The control device automatically detects sensor malfunctions by analyzing data patterns without requiring external diagnostic equipment, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The malfunction detection functionality is merged with the existing control device that already manages seat operations. By combining sensor monitoring and malfunction detection within the existing control architecture rather than adding separate dedicated hardware, the system improves reliability while minimizing complexity increases.

AI summary
A seat experience system that allows an occupant to grasp the state of the system and feel secure about using the system is provided. In the seat experience system, a seat includes a seat body, and a sensor provided at the seat body and configured to acquire a measurement value for detection of a motion of the occupant seated on the seat body. A controller is connected to the sensor and capable of acquiring the measurement value from the sensor, and a seat experience device is connected to the controller and operable based on the measurement value. The seat experience device may be capable of communicating with a server. If the seat experience device detects a malfunction of the seat experience system, the seat experience device notifies the occupant of the malfunction and limits at least a subset of functions of the seat experience system.
