Solution Overview

Problem

Conventional vehicle mounting systems are cumbersome to install and uninstall, and lack a clear indication of tampering or damage, making them inefficient and insecure for transporting various types of equipment.

Innovation Solution

An integrated connector system with attachment ports and plugs on the vehicle's surface, featuring a latching mechanism and control circuitry that provides secure engagement and easy installation/removal, along with an electrical connector for power and status indication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional mounting hardware is used, then mechanical securement is provided, but the system is difficult to install and requires intermediate support structure and adapters

Engineering Contradiction:
Improveease of installationVSAvoidcomplexity of mounting system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the mounting port directly into the vehicle body structure, combining the support function and mounting function into a single integrated component. This eliminates the need for separate intermediate support structures and adapters, thereby simplifying the overall mounting system and making it easier to install.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting port is designed with a universal interface that can accommodate different types of accessories through standardized attachment plugs. The port structure serves multiple functions: providing mechanical support, enabling securement, and facilitating easy installation/removal of various accessories without requiring different mounting systems.

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

2Productivity

If conventional roof racks are used, then mechanical securement is provided, but they are time consuming to uninstall and reinstall

Engineering Contradiction:
Improvespeed of installation and removalVSAvoidtime for uninstallation and reinstallation
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The mounting system incorporates a dynamic latching mechanism that can quickly transition between locked and unlocked states. The latch is designed to engage automatically when the attachment plug is inserted and can be released quickly with a simple actuation, enabling rapid installation and removal without time-consuming manual adjustments.

Inventive Principle:
Principle #15Dynamics

3Reliability

If mechanical mounting hardware is used, then securement is provided, but it is susceptible to mechanical destruction by unauthorized users

Engineering Contradiction:
Improvesecurity against tamperingVSAvoidvulnerability to mechanical destruction
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces purely mechanical mounting hardware with an integrated system that includes electrical connectors and control circuitry. The electrical connection provides an additional layer of security - if the attachment plug is removed or tampered with, the electrical circuit is broken, providing immediate detection of unauthorized access beyond what mechanical securement alone could provide.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Loss of information

If conventional mounting systems are used, then mechanical securement is provided, but there is no indication to the user that securement has been compromised

Engineering Contradiction:
Improveinformation about securement statusVSAvoiddifficulty of detecting tampering
Core Design Contradiction:
Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The mounting system incorporates feedback mechanisms through electrical connectors and control circuitry that continuously monitor the engagement status of attachment plugs. When an attachment plug is properly connected, the electrical circuit is complete, providing confirmation to the user that securement is intact. If the plug is removed or tampered with, the circuit breaks, providing immediate feedback about the compromised securement status.

Inventive Principle:
Principle #23Feedback

AI summary

A vehicle may include an integrated connector system. The vehicle includes a body having an outer surface and a plurality of attachment ports arranged on the outer surface. The attachments ports include a recess that extends below the surrounding outer surface. Each attachment port is configured to receive and engage with an attachment plug of an accessory. In some embodiments, there are different types of attachment ports, configured to engage with respective types of attachment plugs. Various accessories may be engaged with the attachment ports, allowing a range of items and equipment to be secured to the vehicle.
