Modular Vehicle Carrier Rack with Universal Hitch Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier rack systems for motor vehicles are cumbersome, heavy, difficult to store, and not adaptable to all types of vehicles, often causing damage and accessibility issues, while also being susceptible to theft and wind resistance.
Innovation Solution
A modular carrier rack system integrated into a motor vehicle or attachable to a tow hitch, featuring a universal design with a receiving unit and carrier bar that is lightweight, easy to use, and aesthetically hidden, providing improved supportability and storage solutions for recreational equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional carrier rack systems are attached to vehicles using multiple straps or external mounting, then cargo transport capability is provided, but the systems become cumbersome, heavy, and difficult to store
Solution Approach 1:
The carrier bar is designed to nest within the receiving unit when not in use, with the carrier bar featuring a telescoping or collapsible structure that allows it to be stored compactly within the vehicle's receiving structure, eliminating the need for separate storage space
Solution Approach 2:
The system merges the carrier bar and receiving unit into an integrated assembly where the carrier bar connects directly to the receiving unit through universal connections, combining the mounting mechanism and cargo carrier into a single unified system that reduces overall complexity
2Adaptability or versatility
If carrier rack systems are attached to the roof or exterior of vehicles, then cargo carrying capacity is increased, but wind resistance increases and accessibility to trunk/doors is reduced
Solution Approach 1:
The system transitions from traditional roof-mounted or exterior carrier racks to an integrated rear-mounted configuration that utilizes the vehicle's existing structural dimensions, positioning the carrier bar within the rear opening area rather than extending above or beyond the vehicle body, thereby reducing wind resistance and maintaining accessibility
3Adaptability or versatility
If traditional carrier systems are attached to bumpers or tow hitches, then cargo transport is enabled, but vehicle damage risk increases and supportability is limited
Solution Approach 1:
The receiving unit acts as an intermediary structure that distributes cargo loads across multiple attachment points integrated into the vehicle's rear structure, rather than concentrating forces on vulnerable bumper or tow hitch components, thereby protecting the vehicle while providing adequate support
4Adaptability or versatility
If universal tow hitch systems are used, then adaptability to different vehicles is improved, but the systems become heavy and difficult to attach and detach
Solution Approach 1:
The connection mechanism incorporates movable and adjustable components that allow the carrier bar to be quickly inserted into and removed from the receiving unit, with spring-loaded or cam-based locking features that provide automatic engagement and disengagement, making the system easy to operate while maintaining universal compatibility
