Automobile Roof Accessory J-Hook Mount for Wind-Resistant Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile roof accessory attachments using adhesives are not strong enough to securely hold accessories over long periods and resist wind forces during vehicle movement.
Innovation Solution
An attachment assembly comprising an accessory, a washer, a base, and a J-hook (or alternative fastening components) that securely fastens to the automobile roof, providing a stable and wind-resistant mounting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesives are used to attach accessories to the automobile roof, then the installation process is simple, but the attachment strength is insufficient to resist wind forces during vehicle movement
Solution Approach 1:
The patent replaces the chemical bonding mechanism of adhesives with a mechanical fastening system consisting of a base unit with mounting holes, fasteners (screws or clips), and a J-hook. This mechanical system provides superior attachment strength to resist wind forces during vehicle movement while maintaining relatively simple installation through the use of pre-drilled mounting holes and straightforward fastening components.
2Strength
If a mechanical fastening system is used to improve attachment strength, then the attachment can resist wind forces, but the installation complexity increases
Solution Approach 1:
The patent divides the accessory into modular components: a base unit that attaches to the roof, a mounting mechanism with separate fasteners, and the accessory itself. This segmentation allows each component to be optimized independently - the base unit provides structural support, the fasteners provide secure attachment, and the accessory provides the desired function. The modular design simplifies installation by allowing sequential assembly rather than requiring complex integrated systems.
Solution Approach 2:
The base unit serves as an intermediary component between the automobile roof and the accessory. It provides pre-drilled mounting holes and a standardized mounting interface that simplifies the connection process. The J-hook acts as another intermediary that connects the mounting mechanism to the accessory, creating a standardized interface that reduces installation complexity while maintaining high attachment strength.
3Ease of operation
If adhesives are used for attachment, then the installation is easy, but the durability and long-term stability are insufficient
Solution Approach 1:
The patent replaces the chemical bonding mechanism of adhesives with a mechanical fastening system that provides superior long-term reliability. The mechanical connection through bolts, screws, or clips creates a rigid, load-bearing attachment that can withstand vibration, temperature variations, and wind forces over extended periods, unlike adhesives that may degrade or lose bonding strength over time.

AI summary
The present invention is an accessory to be attached to the roof of a motor vehicle. The roof accessory comprises an antler, a J-hook, and an attachment unit that is used to secure the antler to the roof. The attachment unit has a divot centrally located that bears a slot across the divot. The slot allows a J-hook with a screw column to come up through the slot, and be screwed into the bottom surface of the antler. The bottom surface of the antler has threading that connects with the threading on the screw column.
