Vehicle Seat Adjustment via Mobile Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat adjustment systems require pre-stored physique data for each driver, which is inconvenient and inefficient.
Innovation Solution
A communication apparatus and system that wirelessly communicates with a mobile terminal to estimate the terminal's position within a vehicle, specify the closest seat, and acquire adjustment data from the terminal to adjust the seat without pre-storing physique data in the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physique data is pre-stored in a storage unit inside the vehicle, then seat adjustment can be performed based on stored driver information, but the system requires additional storage capacity and data management complexity
Solution Approach 1:
The patent extracts the physique data storage function from the vehicle's internal storage unit and relocates it to the mobile terminal. The vehicle's communication apparatus receives adjustment data wirelessly from the mobile terminal, eliminating the need for the vehicle to store physique data locally. This resolves the contradiction by maintaining seat adjustment convenience while removing the requirement for internal data storage.
Solution Approach 2:
The patent introduces a mobile terminal as an intermediary between the driver and the vehicle's seat adjustment system. The mobile terminal stores physique data and communicates it wirelessly to the vehicle's communication apparatus, which then transmits the data to the seat adjuster. This intermediary approach allows the vehicle to perform seat adjustment without storing data internally, resolving the contradiction between operational convenience and data storage requirements.
2Adaptability or versatility
If multiple pieces of physique data are written in advance in the storage unit, then the system can support multiple drivers, but the device complexity and data management burden increase
Solution Approach 1:
The patent implements self-service by allowing each driver to store their own physique data in their personal mobile terminal. When a driver approaches the vehicle, their mobile terminal automatically transmits their adjustment data to the vehicle's communication apparatus. This eliminates the need for the vehicle system to manage multiple driver profiles, resolving the contradiction between multi-driver support and data management complexity.
Solution Approach 2:
The patent segments the physique data management function from the central vehicle system and distributes it to individual mobile terminals. Each mobile terminal independently stores and manages its owner's physique data, while the vehicle's communication apparatus simply receives and forwards the data to the appropriate seat adjuster. This segmentation resolves the contradiction by maintaining multi-driver versatility while eliminating centralized data management complexity.

AI summary
A plurality of seats are arranged in a vehicle. A communication apparatus is mounted in the vehicle and communicates wirelessly with a mobile terminal. The communication apparatus estimates the position of the mobile terminal inside the vehicle based on information obtained through communication with the mobile terminal, and specifies the seat closest to the estimated position among the plurality of seats. The communication apparatus acquires adjustment data needed for adjusting the specified seat from the mobile terminal.
