Solution Overview

Problem

Existing accessory attachment systems for vehicles are cumbersome and require professional installation or complicated coupling processes, and they do not provide adequate vehicle departure angles, especially in uneven terrain.

Innovation Solution

A retention bracket and removable accessory bracket system with two sets of connectors, where a first set allows relative rotation and a second set limits rotation, facilitated by C-shaped connectors and optional electronic actuation, simplifying installation and enhancing vehicle departure angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional accessory attachment systems are used, then the accessory can be securely attached to the vehicle, but the installation process is cumbersome and requires professional installation or complicated coupling processes

Engineering Contradiction:
ImproveInstallation easeVSAvoidCoupling process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The attachment system is divided into separate components: a retention bracket that attaches to the vehicle and a removable accessory bracket that can be independently installed and removed. This segmentation allows the complex coupling mechanism to be pre-assembled on the vehicle side, simplifying the user's installation task to merely attaching the removable bracket.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retention bracket serves as an intermediary component between the vehicle and the removable accessory bracket. It contains the complex coupling mechanism with connectors and receiving structures, acting as a mediator that simplifies the interaction between the user and the attachment system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If traditional accessory attachment systems are used, then the accessory can be attached to the vehicle, but the vehicle departure angle is inadequate, especially in uneven terrain

Engineering Contradiction:
ImproveVehicle maneuverabilityVSAvoidVehicle departure angle
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The attachment system allows the removable accessory bracket to be easily installed and removed, enabling dynamic adjustment of the vehicle's rear profile. When not in use, the bracket can be removed to maximize the vehicle's departure angle for off-roading conditions.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the accessory bracket is made permanently fixed, then the attachment is secure and stable, but the accessory cannot be easily removed or stored when not in use

Engineering Contradiction:
ImproveAccessory removabilityVSAvoidAttachment stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system separates the attachment mechanism into a fixed retention bracket and a removable accessory bracket. This segmentation enables the accessory to be easily removed and stored while maintaining secure attachment during use through the engineered coupling mechanism with multiple connectors and receiving structures.

Inventive Principle:
Principle #1Segmentation

AI summary

Some embodiments may provide an accessory attachment system for a vehicle. The system may include a retention bracket and a removable accessory bracket. The retention bracket may be configured to attach to the vehicle. The retention bracket may include a first retention connector and a second retention connector. The removable accessory bracket may include a first accessory connector and a second accessory connector. The first accessory connector may include a C-shape. The first accessory connector may be configured to couple to the first retention connector and may enable a rotation of the removable accessory bracket relative to the retention bracket. The second accessory connector may be configured to couple to the second retention connector and may limit the rotation of the removable accessory bracket relative to the retention bracket.
