Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat systems fail to enhance occupant motivation and provide secure operation by notifying users of malfunctions, while also being inefficient in power consumption and communication reliability.
Innovation Solution
A seat experience system with sensors to detect occupant motion, a controller to process data, and a device to notify users of malfunctions, limiting system functions if necessary, and allowing operation via body motion without hand interaction, with power-saving features and offline capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat experience system continuously monitors sensor data and provides real-time feedback, then user engagement and motivation are improved, but power consumption increases
Solution Approach 1:
The control unit performs malfunction determination periodically at predetermined intervals rather than continuously monitoring sensor data. This periodic checking mechanism maintains user engagement through regular system responsiveness while significantly reducing power consumption compared to continuous monitoring approaches.
Solution Approach 2:
The system automatically detects sensor malfunctions and notifies occupants without requiring continuous manual verification. The self-monitoring capability ensures system reliability and maintains user trust while operating efficiently with periodic checks rather than continuous power-intensive monitoring.
2Reliability
If the system provides comprehensive malfunction detection and notification, then system reliability is improved, but device complexity increases
Solution Approach 1:
The malfunction determination function is extracted as a separate, dedicated process within the control unit. This modular approach isolates the complexity of malfunction detection logic from other system functions, making the overall system more manageable and maintainable while ensuring reliable malfunction detection and notification.
Solution Approach 2:
The system implements a feedback loop where sensor data is continuously analyzed against predetermined thresholds, and malfunction notifications are automatically generated when anomalies are detected. This automated feedback mechanism ensures high system reliability without requiring complex manual monitoring procedures.
3Measurement precision
If the sensor operates continuously to detect occupant motion, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The sensor operates periodically at predetermined intervals rather than continuously, checking for occupant motion and system malfunctions at scheduled times. This periodic operation maintains adequate measurement precision for safety-critical functions while dramatically reducing power consumption compared to continuous sensor activation.
Solution Approach 2:
The system changes the operational parameters of the sensor based on system state, switching between active measurement modes and low-power states. This parameter adjustment allows the sensor to maintain high precision when needed while consuming minimal power during normal operation, resolving the trade-off between measurement quality and energy usage.

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.
