Solution Overview

Problem

Current seat control technologies in vehicles are limited in providing a comfortable entry and exit experience due to restrictive seat adjustment capabilities, making it difficult to optimize seating states for user convenience.

Innovation Solution

A seat control apparatus comprising a sensor device, driving device, memory, and control device that identifies user intent to get on or off a vehicle, storing and adjusting seat positions such as slide, tilt, and legrest locations based on real-time data and conditions like vehicle state and door openness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the seat control apparatus provides multiple seat adjustment capabilities (slide, tilt, legrest), then the user's entry and exit comfort is improved, but the device complexity increases

Engineering Contradiction:
Improveuser entry and exit comfortVSAvoidseat adjustment mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control device stores optimal seat states (slide position, tilt angle, legrest position) in advance for different user scenarios. When a user approaches the vehicle, the system retrieves and applies the pre-stored seat configuration, eliminating the need for users to manually adjust multiple seat components and reducing the perceived complexity of the adjustment mechanism.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The seat control apparatus automatically detects user presence and intent through sensor devices, then autonomously adjusts the seat to the appropriate state without user intervention. The system self-manages the coordination of slide, tilt, and legrest adjustments, reducing the operational burden on users despite the multi-component adjustment mechanism.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If the sensor device continuously monitors user intent and vehicle state, then the adaptability of seat control is improved, but the energy consumption increases

Engineering Contradiction:
Improveseat control adaptabilityVSAvoidsensor device energy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The sensor device operates in periodic cycles rather than continuous monitoring. The control device activates sensors at specific moments (e.g., when vehicle ignition is on, when door is approached, or at scheduled intervals) to detect user intent and vehicle state, then enters a low-power state between measurements. This periodic operation maintains system adaptability while significantly reducing overall energy consumption compared to continuous monitoring.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses feedback from sensor detections to dynamically adjust monitoring intensity. When user presence is detected, the sensor device increases monitoring frequency to capture real-time intent changes. When no user is present, the system reduces monitoring to minimal periodic checks, optimizing the balance between adaptability and energy consumption based on actual operational needs.

Inventive Principle:
Principle #23Feedback

AI summary

A seat control apparatus includes a sensor device, a driving device, a memory, and a control device. The control device is configured to: identify an intent of a user getting on a host vehicle by using the sensor device; identify a state of a seat corresponding to the user, when the intent of the user satisfies a specified condition; store the identified state of the seat in the memory; and control at least one of a slide location of the seat, a tilt location of the seat, a legrest location of the seat, or a combination thereof of the seat by using the driving device based on the state of the seat.
