Solution Overview

Problem

Existing systems fail to optimally adjust vehicle controls and seating based on the size of a person approaching, leading to uncomfortable and inconvenient entry experiences, especially in rental and autonomous vehicles.

Innovation Solution

A method and apparatus that detect the size of a person or object approaching a vehicle using sensors, such as cameras, and adjust vehicle controls, mirrors, and seating positions accordingly, including determining the height difference and intended entry trajectory, to ensure optimal positioning before entry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If vehicle controls and seating are manually adjusted after entry, then the person can achieve comfortable positioning, but this increases the time required to prepare the vehicle and reduces convenience

Engineering Contradiction:
ImproveConvenience of vehicle preparationVSAvoidTime to adjust controls and seating
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary detection of the person's size and characteristics before they enter the vehicle, and pre-adjusts the seating position, mirror angles, and control configurations in advance. This eliminates the need for manual adjustment after entry, reducing preparation time while maintaining comfort.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The vehicle system automatically detects the occupant's physical characteristics and self-adjusts the interior components without requiring manual input from the occupant. The system serves itself by using sensors to gather data and actuators to make adjustments autonomously.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If the vehicle uses a fixed seating and control configuration, then the device complexity is reduced, but this worsens the comfort and adaptability for different sized persons

Engineering Contradiction:
ImproveAdaptability to different person sizesVSAvoidComplexity of detection and adjustment system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system replaces complex manual adjustment mechanisms with automated detection and adjustment systems. Sensors (optical, ultrasonic, or capacitive) detect the occupant's physical characteristics, and electronic control systems automatically adjust the seating and controls, substituting mechanical complexity with sensor-based automation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes physical parameters such as seating position, backrest angle, mirror orientation, and control reach based on detected occupant characteristics. By dynamically adjusting these parameters according to the occupant's size and preferences, the system achieves adaptability without requiring multiple fixed configurations.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If the vehicle detects person size using multiple sensors and cameras, then the measurement precision of person size is improved, but this increases the device complexity and cost

Engineering Contradiction:
ImprovePrecision of person size detectionVSAvoidNumber of sensors and cameras
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses multi-functional sensors that can perform multiple detection tasks. For example, cameras serve both for detecting the occupant's approach trajectory and for measuring physical dimensions. This multi-functionality reduces the need for dedicated sensors for each measurement task, thereby reducing overall system complexity while maintaining precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
