Pressure-Sensing Seat Control for Height Adjustment and Immersive Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats lack the ability to provide immersive experiences through bodily sensations and fail to accurately adjust the seat height based on occupant movements, leading to suboptimal comfort and entertainment value.
Innovation Solution
A seat system equipped with pressure sensors and a controller that adjusts the seat height and interacts with a screen display to simulate experiences, such as a safari game, by detecting user motions and controlling movable objects on the screen, while using a height-adjustment mechanism to optimize seat and footrest positions based on pressure sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a plurality of pressure sensors are provided on the seat to detect sitting posture, then the sitting posture detection capability is improved, but the device complexity increases
Solution Approach 1:
The seat cushion is divided into multiple regions with pressure sensors strategically placed at specific locations (front, middle, rear portions) rather than uniformly distributed. This segmentation approach enables effective sitting posture detection while minimizing the total number of sensors required, thus reducing device complexity.
Solution Approach 2:
The pressure sensors serve multiple functions: detecting sitting posture, determining seat height adjustment needs, and enabling entertainment interactions. This multi-functionality reduces the need for separate detection systems, thereby improving measurement capability without proportionally increasing device complexity.
2Ease of operation
If the seat height is adjusted based on pressure detection, then the comfort is improved, but the device complexity increases
Solution Approach 1:
The system continuously monitors pressure distribution through the sensors and provides real-time feedback to the seat height adjustment mechanism. This feedback loop enables automatic comfort optimization without requiring complex manual control systems, as the sensors directly inform the adjustment needs.
Solution Approach 2:
The seat system automatically adjusts its own height based on pressure sensor data without requiring external intervention or complex control interfaces. The pressure detection mechanism directly triggers the appropriate height adjustment, enabling the system to self-optimize for comfort.
3Adaptability or versatility
If the seat provides entertainment experiences through sensor detection, then the entertainability is improved, but the device complexity increases
Solution Approach 1:
The pressure sensors simultaneously serve detection functions and entertainment control functions. The same sensor data used for posture detection also drives the entertainment interactions, allowing the system to provide multiple functions without adding separate hardware systems.
Solution Approach 2:
The detection system and entertainment system are merged into a single integrated architecture where pressure sensor data controls both comfort features and entertainment interactions. This consolidation reduces overall device complexity by eliminating redundant components.
4Device complexity
If pressure sensors are provided only at the front and rear of the seat bottom, then the device complexity is reduced, but the measurement precision for leg motion detection deteriorates
Solution Approach 1:
The seat bottom is divided into multiple detection zones with sensors placed at the front, middle, and rear portions. This segmentation enables precise detection of leg motions at different locations without requiring sensors throughout the entire seat, maintaining low device complexity while improving measurement precision.
