Collapsible Spare Tire Accessory Mount for Adjustable Vehicle Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mounting accessories on vehicles are limited by their requirement for trailer hitches, irreversible modifications, interference with vehicle doors, and lack of compatibility with varying tire sizes, making them inconvenient and restrictive.
Innovation Solution
A collapsible accessory mount system that attaches to the external spare tire, featuring telescoping arms with adjustable length and a central bracket, allowing for secure attachment and easy storage, with features like latches and a flagpole for versatile accessory mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional mounting bracket is used on the external tire, then the accessory can be securely mounted, but the bracket becomes as large as the tire itself, making it difficult to transport and store
Solution Approach 1:
The mounting bracket is divided into multiple telescoping arms that can be segmented and collapsed into a compact configuration for storage, while still providing sufficient span when deployed to securely mount accessories on the tire
Solution Approach 2:
The bracket employs telescoping arms with adjustable lengths that can dynamically extend to accommodate different tire sizes and collapse to a compact form for storage, transforming the bracket from a static large structure to a dynamic compact system
2Reliability
If a fixed-size mounting bracket is used, then it can securely mount accessories, but it must be made to fit a particular size of tire, limiting compatibility with varying tire sizes and models
Solution Approach 1:
The telescoping arms can extend and contract to different lengths, allowing the same bracket design to adapt to various tire diameters and widths, thereby achieving universal compatibility across different tire sizes and vehicle models while maintaining secure mounting capability
Solution Approach 2:
The bracket's effective dimensions are made variable through telescoping mechanisms, allowing the mounting span and reach to be adjusted to match different tire parameters (diameter, width, mounting surface distance), enabling the same bracket to securely fit multiple tire sizes
3Reliability
If a non-collapsible mounting system is used, then accessories can be securely mounted, but the system cannot be easily stored or transported when not in use
Solution Approach 1:
The mounting system is segmented into multiple telescoping arms that can be collapsed into a compact bundle for storage and transported easily, while still providing secure attachment when deployed and locked into position
Solution Approach 2:
The telescoping arms can be nested within each other in a collapsed state for compact storage, similar to a nested doll structure, allowing the entire mounting system to be reduced to a small package that is easy to store and transport

AI summary
A collapsible accessory mount provides a secure way to attach accessories, such as a flag, banner, light, loudspeaker, camera, basket or other such device, to an automobile using an external spare tire as a mounting point. The external spare provides solid mounting surface for attaching a collapsible accessory mount without interfering with access to the trunk or rear hatch of the vehicle, and may be installed and removed without making permanent modifications to the vehicle frame or chassis. A collapsible accessory mount includes a central bracket and a plurality of arms, each arm configured to extend beyond the radius of the automobile tire, where each of said arms may be releasably attached to the tire using tire connectors.
