Solution Overview

Problem

Current vehicle input devices can cause visual distraction for drivers due to their fixed positions, which do not accommodate the varying physical characteristics of users, leading to inconvenient manipulation and potential safety issues.

Innovation Solution

A movable input device for vehicles equipped with a detector (including bio-signal sensors and pressure sensors) that adjusts its position based on the user's wrist and elbow location, allowing for intuitive control without diverting the driver's attention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the input device is positioned at a fixed location, then the device structure is simple, but the driver's visual distraction increases and manipulation convenience deteriorates

Engineering Contradiction:
Improvemanipulation convenienceVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The input device is transformed from a static fixed-position device to a dynamic movable device that can automatically adjust its position based on the driver's wrist location detected by sensors, thereby improving manipulation convenience without requiring manual adjustment

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The input device performs self-positioning by detecting the driver's wrist position and automatically moving to the optimal location, eliminating the need for the driver to manually adjust the device position and reducing visual distraction

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If the input device is moved to accommodate different users, then manipulation convenience improves, but the device complexity increases

Engineering Contradiction:
Improveuser adaptationVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The input device incorporates multiple detection functions (wrist position detection, pulse detection) and movement capabilities into a single universal device that can adapt to different users and scenarios, improving versatility without proportionally increasing complexity

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

Solution Approach 2:

The device uses feedback from pulse sensors and position detectors to automatically adjust its position, creating a closed-loop system that adapts to different users based on their physiological signals and physical characteristics

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the input device requires manual adjustment, then the device structure is simple, but the driver's attention is diverted from driving

Engineering Contradiction:
Improveoperation simplicityVSAvoiddriving safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The input device performs self-positioning by detecting the driver's wrist position and automatically moving to the optimal location, eliminating the need for the driver to manually adjust the device position and reducing visual distraction

Inventive Principle:
Principle #25Self-service
