Solution Overview

Problem

Users feel anxious when a third-party worker charges their vehicle while they are away, as the worker may perform unauthorized operations due to the need to unlock the vehicle door and charging port.

Innovation Solution

A vehicle-mounted camera captures images of the interior when unlocked by a predetermined worker, allowing users to monitor the charging process through a user terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a worker unlocks the vehicle door and charging port to perform charging service, then the charging operation can be completed, but the user feels anxious about unauthorized operations due to the worker's access to the vehicle interior

Engineering Contradiction:
Improvecharging service operationVSAvoiduser security perception
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system implements real-time video feedback by transmitting camera images of the vehicle interior to the user's terminal device. This allows the user to monitor the worker's actions during charging, providing transparency and reducing anxiety about unauthorized operations while maintaining smooth charging service delivery

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

A camera system acts as an intermediary between the worker and the user. The camera captures images of the vehicle interior and transmits them to the user's terminal, creating a virtual presence that allows the user to observe without being physically present, thus enabling the worker to operate freely while the user maintains security awareness

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A vehicle includes a camera, a detection mechanism, and a processor. The camera is mounted on the vehicle and captures images of the vehicle's interior. The detection mechanism detects that the vehicle is unlocked by an authorized worker. Upon detection of such unlocking, the processor triggers the camera to capture images within a predetermined range.
