Custom Vehicle Seat Design Using Real Driving Posture Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat customization systems fail to consider the driving environment when designing seats, leading to suboptimal comfort and efficiency.
Innovation Solution
A vehicle seat ordering system that includes a sensor-equipped seat for measurement, which detects occupant posture and environmental conditions during vehicle operation, and a seat design device that customizes the seat based on this data to fit the user's physique and driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robot seat is adjusted in a static state in a shop, then the seat can be customized by the user, but it is impossible to customize the seat in consideration of the actual driving environment of the vehicle
Solution Approach 1:
The patent applies preliminary action by having the user temporarily install a measurement seat in their vehicle and collect posture data during actual driving conditions before the final seat is manufactured. This preliminary data collection phase allows the system to analyze real driving environment effects (road undulations, acceleration, deceleration) and pre-calculate optimal seat specifications, thereby resolving the contradiction between adapting to the driving environment and reducing design time.
2Device complexity
If sensors detect pressure and acceleration in the seat body, then the seat for measurement has a relatively simple configuration, but it requires detecting multiple parameters simultaneously
Solution Approach 1:
The patent uses the seat body itself as an intermediary structure that naturally experiences and transmits the forces of interest. Pressure sensors detect the distribution of forces on the seat surface, while acceleration sensors mounted on the seat body capture the dynamic motion. This intermediary approach simplifies the overall system by using the existing seat structure as the measurement platform, avoiding the need for complex external measurement apparatus while still achieving accurate posture detection through the combination of pressure distribution patterns and acceleration data.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables the design of seats that enhance comfort and reduce time constraints by considering actual driving conditions, allowing users to visualize improvements and place orders remotely.
Implementation Method 1
the sensor may be configured to detect pressure received by the seat body from the occupant and acceleration generated in the seat body
Implementation Method 2
the sensor may be configured to detect pressure received by the seat body from the occupant and acceleration generated in the seat body
