Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mechanical locking arrangements are used for seat installation, then the seat can be securely fixed, but the installation position identification is imprecise and time-consuming
Solution Approach 1:
The patent replaces traditional mechanical position identification methods with electronic sensing systems. Resistance measurement devices, RFID sensors, or NFC sensors are integrated into the seat and vehicle structure to automatically detect and identify installation positions through electrical or electromagnetic signals, eliminating the need for manual mechanical verification and significantly improving both precision and speed of position identification
Solution Approach 2:
The seat system performs self-identification of its installation position through integrated sensors that automatically detect resistance values, RFID tags, or NFC signals at different mounting locations. This self-service capability eliminates the need for external assistance or manual verification during installation, reducing installation time while maintaining high positional accuracy
2Measurement precision
If multiple sensing methods (resistance, RFID, NFC) are implemented, then position identification precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional sensing architecture where a single electronic control unit can interface with multiple types of sensors (resistance measurement devices, RFID sensors, NFC sensors). This universal design allows the system to use different sensing methods depending on availability and requirements, improving position detection accuracy without proportionally increasing overall system complexity through shared control electronics and integrated processing
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
This method enables precise identification of the vehicle seat's installation position, ensuring correct alignment and easy installation, thereby enhancing comfort and reducing installation time.
Implementation Method 1
the electronic seat control unit is designed, following installation of the vehicle seat at one of the positions in the vehicle, to determine and optionally to output at least the adopted installation position of the vehicle seat by means of a resistance measurement
Implementation Method 2
instead of a resistance, the adopted installation position of the vehicle seat in the vehicle can be determined via an RFID sensor at the seat position in the vehicle
Implementation Method 3
A further alternative envisions that the adopted installation position of the vehicle seat in the vehicle is determined via an NFC sensor at the seat position in the vehicle

AI summary
A vehicle seat for variable installation in different installation positions in a vehicle interior of a vehicle is provided. The vehicle seat may have an electronic seat control unit which is designed, following or during installation of the vehicle seat in one of the installation positions in the vehicle, to determine at least the assumed installation position of the vehicle seat via a resistance measurement and/or a contactless measurement by means of an RFID sensor or an NFC sensor. A vehicle having at least one vehicle seat, which can be installed variably in different installation positions in the vehicle interior, and to a method for identifying an installation position of a vehicle seat in a vehicle, are also provided.
