Solution Overview

Problem

Existing retractable camping awnings and other roof rack-mounted accessories are difficult to remove and reattach, often remaining undesirably on vehicles after use, and require disassembly when the vehicle is used elsewhere.

Innovation Solution

A roof rack coupler with a roof rack member, accessory member, and securing means, allowing for quick and secure attachment and detachment of accessories like awnings or storage tubes, featuring a pivoting mechanism, pin member, and optional lock for rapid assembly and disassembly, enabling the accessory to remain erected when the vehicle moves.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing retractable camping awnings are attached to roof racks, then the awnings can be mounted on vehicles, but they become difficult to remove and reattach, often remaining undesirably on vehicles after use

Engineering Contradiction:
Improveease of attachment and detachmentVSAvoidtime required for removal and reattachment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The coupler is divided into separate components: a roof rack member that attaches to the vehicle roof rack, and an accessory member that attaches to the awning. These segments can be independently attached and detached, allowing rapid assembly and disassembly without complex multi-step procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupler incorporates a pivoting mechanism that allows the accessory member to pivot relative to the roof rack member. This dynamic feature enables quick engagement and disengagement through simple lifting and pivoting motions, dramatically reducing the time and effort required for attachment and detachment operations.

Inventive Principle:
Principle #15Dynamics

2Reliability

If accessories are securely attached to the roof rack, then they remain firmly in place during vehicle travel, but they require complex securing mechanisms that make removal difficult

Engineering Contradiction:
Improvesecurity of attachmentVSAvoidcomplexity of securing mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The pivoting mechanism provides both security and simplicity. When engaged, the pivot creates a firm mechanical connection that reliably secures the accessory during travel. The same pivoting action, combined with a simple lifting motion, enables easy release without complex tools or procedures, thus achieving both reliability and low complexity simultaneously.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pin member acts as an intermediary element that simplifies the securing process. It provides a straightforward insertion and locking mechanism that ensures reliable attachment while maintaining operational simplicity. The pin can be quickly inserted or removed without complex procedures, bridging the gap between secure attachment and ease of removal.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the accessory member is substantially received within the roof rack member, then a streamlined coupler is provided for minimal drag, but access to securing components may be limited

Engineering Contradiction:
Improveaerodynamic dragVSAvoidaccess to securing components
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The securing components, particularly the pin member, are positioned at the base of the members where they are substantially received within each other. This spatial arrangement in a different dimension (at the base rather than along the length) provides access to securing components while maintaining the streamlined profile along the aerodynamic surface, thus reducing drag without compromising accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present invention relates to a roof rack coupler for coupling an accessory to a roof rack. The coupler includes a roof rack member for fastening to the generic roof rack bracket. The coupler further includes an accessory member, typically releasably fastenable to the accessory, for engaging with the roof rack member. Securing means is provided for securing the accessory member to the roof rack member. Preferably, the accessory member may be dropped within and lifted out of the roof rack member to facilitate rapid assembly and disassembly.
