Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current vehicle backup systems rely solely on sensors to navigate in reverse, which can lead to driver anxiety and potential collisions, as they do not allow for user interaction or verification of paths and obstacles.

Innovation Solution

A vehicle system equipped with a camera, touch panel screen, and processor that enables users to input paths or avoid objects by tracing on the screen or using voice commands, allowing the vehicle to execute driving commands autonomously or semi-autonomously.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system relies solely on sensors to navigate in reverse, then the system complexity is reduced, but driver confidence and safety are compromised due to lack of user interaction and verification capability

Engineering Contradiction:

Improvedriver confidenceVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The touch panel screen acts as an intermediary between the driver and the autonomous driving system. It displays the camera feed and allows the driver to interact with the system by drawing paths or selecting objects, providing verification capability while maintaining system automation

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system provides visual feedback by displaying the camera feed on the touch panel screen, allowing the driver to verify the system's perception and planned path. This feedback loop enhances driver confidence and situational awareness

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the system allows full autonomous operation without user input, then ease of operation is improved, but safety is reduced due to inability to verify paths and avoid obstacles

Engineering Contradiction:

Improveease of operationVSAvoidsafety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system implements semi-autonomous operation where the autonomous system handles basic navigation but requires partial user action (drawing path or selecting objects) for verification. This partial user involvement enhances safety while maintaining ease of operation

Inventive Principle:

Principle #16Partial or excessive action

3Productivity

If the system requires no user interaction, then productivity is improved through fully autonomous operation, but driver confidence and safety are reduced

Engineering Contradiction:

Improveoperational efficiencyVSAvoiddriver confidence

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The driver serves themselves by interacting with the touch panel to verify and adjust the driving path. This self-service approach maintains operational efficiency while building driver confidence through active verification

Inventive Principle:

Principle #25Self-service

AI summary

A vehicle system may include a camera configured to output imagery of a surrounding of a vehicle. The vehicle system may also include a touch panel screen configured to display the imagery and receive one or more inputs from a finger of a user when the imagery is displayed on the touch panel screen. The vehicle system may further include a processor in communication with the camera and touch panel screen, wherein the processor is programmed to associate a path for the vehicle to drive in response to the one or more inputs from the finger and execute one or more driving commands to operate the vehicle along the path in reverse.
