Solution Overview

Problem

Conventional in-vehicle devices, such as drive recorders, have integrated bases and main bodies that limit the ability to capture scenes other than the front of the vehicle or occupants in the cabin, necessitating improved usability.

Innovation Solution

The in-vehicle device integrates a main body part and a pedestal part using magnetic forces, allowing for adjustable attachment and detachment, enabling flexible positioning and orientation of the camera to capture various scenes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the base and main body part are substantially integrated, then the structure is simple and reliable, but the ability to capture scenes other than the front of the vehicle or occupants in the cabin is limited

Engineering Contradiction:
Improveability to capture various scenesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The in-vehicle device is divided into two separate parts: a base that mounts to the windshield and a main body part containing the camera. These parts are connected through a pivotable connection mechanism, allowing the main body part to be rotated and positioned independently to capture various scenes including side views, rear views, and cabin interiors, while the base remains fixed on the windshield.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the main body part and pedestal part are rigidly integrated, then the connection is strong and stable, but the optical axis direction cannot be adjusted

Engineering Contradiction:
Improveadjustability of optical axisVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connection between the main body part and base is made dynamic through a pivotable joint mechanism. This joint allows the main body part to rotate freely to adjust the optical axis direction while incorporating a locking mechanism that can secure the connection at any desired angle, providing both adjustability and connection stability.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the base is fixed to the windshield, then the mounting is stable, but the device cannot be repositioned or reoriented

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidmounting mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device separates the mounting function (base) from the camera housing (main body part). The base is designed to be fixed to the windshield with a simple mounting mechanism, while the main body part connects to the base through a pivotable joint, allowing repositioning and reorientation without requiring complex adjustments to the windshield mounting itself.

Inventive Principle:
Principle #1Segmentation

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

The magnetic attachment system allows for independent adjustment of the camera's optical axis, enhancing usability by enabling capture of scenes other than the front of the vehicle and improving reliability against external forces.

Implementation Method 1

a magnet provided on one of the main body part and the pedestal part; and a magnetic body provided on another of the main body part and the pedestal part, wherein the main body part has an outer circumferential surface of a curved surface having at least an arc shape with a first radius in a transverse cross section orthogonal to the first direction, the pedestal part has an inner circumferential surface that is recessed inward as a curved surface having the first radius, and the outer circumferential surface and the inner circumferential surface are magnetically attached due to a magnetic force of the magnet, which integrates the main body part and the pedestal part

AI summary

An in-vehicle device includes a main body part, a pedestal part, a magnet, and a magnetic body. The main body part has a shape with a first direction as a longitudinal direction. The magnet is provided on one of the main body part and the pedestal part. The magnetic body is provided on the other of the main body part and the pedestal part. The main body part has an outer circumferential surface of a curved surface having at least an arc shape with a first radius in a transverse cross section orthogonal to the first direction. The pedestal part has an inner circumferential surface that is recessed inward as a curved surface having the first radius. The outer circumferential surface and the inner circumferential surface are magnetically attached due to a magnetic force of the magnet, which integrates the main body part and the pedestal part.
