Solution Overview

Problem

Conventional vehicle door handles that protrude externally hinder vehicle aesthetics, cause noise due to air resistance, and reduce driving performance.

Innovation Solution

A vehicle door handle equipped with a camera module that is integrated into a flush handle, which can be automatically or manually operated to protrude from the door panel, and includes a motor module for rotating the camera, a cleaner for lens maintenance, and a design that minimizes external exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the door handle protrudes to the outside of the vehicle, then the door handle can be easily gripped by an occupant, but it hinders the appearance of the vehicle, causes noise due to air resistance, and reduces driving performance

Engineering Contradiction:
Improveease of grippingVSAvoidaerodynamic resistance
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The door handle is designed to dynamically change its position between protruding and retracted states. During driving, it remains retracted to minimize aerodynamic resistance and improve appearance. When door opening is detected, it protrudes to enable easy gripping. This dynamic adaptation resolves the contradiction between ease of operation and aerodynamic performance.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The door handle integrates multiple functions: it serves as both a manual gripping point for door opening and a mounting platform for the camera module. The camera module itself becomes part of the handle structure, allowing the handle to perform surveillance functions while maintaining its primary door-opening function, thus addressing both ergonomic and aesthetic requirements.

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

2Ease of operation

If the door handle protrudes to the outside of the vehicle, then the door handle can be easily gripped by an occupant, but it hinders the appearance of the vehicle

Engineering Contradiction:
Improveease of grippingVSAvoidvehicle appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The door handle transitions between protruding and retracted states based on operational needs. When retracted, it maintains a flush appearance with the door surface, enhancing vehicle aesthetics. When protruding, it provides the necessary grip for door opening, thus resolving the appearance-ergonomics contradiction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The camera module is nested within the door handle structure, with the handle serving as both a functional gripping element and a housing for the camera. This nesting allows the camera to be integrated seamlessly into the handle design, maintaining aesthetic appearance while enabling surveillance functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Loss of information

If the camera module is exposed to the outside of the handle housing, then the camera can photograph surroundings of the vehicle, but the lens may be contaminated

Engineering Contradiction:
Improvesurrounding visibilityVSAvoidlens contamination
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

A protective cover is introduced as an intermediary element between the camera lens and the external environment. The cover remains transparent to allow light transmission for photography but physically blocks contaminants from reaching the lens. The cover can open or retract when door opening is detected, enabling camera operation while protecting the lens during normal driving conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective cover is positioned in advance to shield the lens before contamination can occur. The cover is designed to be transparent, allowing the camera to capture images without direct exposure to external contaminants. This preliminary protection mechanism prevents lens contamination while maintaining imaging capability.

Inventive Principle:
Principle #10Preliminary action

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

Enhances vehicle aesthetics, reduces noise, improves aerodynamics, and provides enhanced field of view by integrating a camera for surrounding monitoring, while maintaining functionality and cleanliness.

Implementation Method 1

a motor module operable to rotate the camera module

Methodology Applied
Scientific EffectMechanical rotation:

Implementation Method 2

a link screw connected to the motor body and rotated by an operation of the motor body, and a screw bar. One end of the screw bar is connected to the camera module and the other end of the screw bar is connected to the link screw, and thus the screw bar may move according to a rotation of the link screw

Methodology Applied
