Solution Overview
Problem
Conventional hitch attachment systems are not adaptable for multiple uses, requiring separate attachments for different activities, are often bulky and difficult to install, and lack adjustability and storage efficiency.
Innovation Solution
A modular vehicle hitch system with interchangeable accessory attachments, featuring a vehicle mount, connector, and support frame that allows for adjustable positioning and folding, enabling secure transport and use of various equipment types without the need for multiple attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional hitch attachments are designed for specific purposes, then they can securely support intended equipment, but they cannot adapt to different activities or equipment types
Solution Approach 1:
The hitch attachment system is designed with a universal base attachment and multiple interchangeable accessory attachments that can be mounted to the same base. The base includes a receiver tube and mounting structure that accommodates different accessory types (grill attachments, bike racks, cargo carriers, etc.), allowing a single base to support multiple functions and equipment types throughout the vehicle's lifetime.
Solution Approach 2:
The system divides the hitch attachment into separate modular components: a permanent base attachment and removable accessory attachments. This segmentation allows the base to remain installed on the vehicle while different accessories are swapped as needed, reducing the need to install multiple complete attachment systems and enabling flexible adaptation to different activities.
2Strength
If conventional hitch attachments include large support structures, then they can support equipment weight, but they become heavy and awkward to lift and install
Solution Approach 1:
The system separates the heavy-duty base attachment (which remains installed on the vehicle) from the lighter accessory attachments (which are removed and replaced as needed). The base contains the primary structural support and mounting hardware, while accessories are designed to be lighter and easier to handle, yet still provide adequate support for their specific equipment when mounted to the base.
Solution Approach 2:
The base attachment is pre-installed on the vehicle with all necessary mounting hardware and structural components already in place. This preliminary installation of the heavy support structure eliminates the need to repeatedly lift and install heavy components when changing accessories, as only the lighter accessory attachments need to be handled during swaps.
3Reliability
If conventional hitch attachments use traditional fastening methods, then they can securely attach equipment, but they require tools and are difficult to install without assistance
Solution Approach 1:
The system extracts the complex fastening mechanism from the accessory attachments and concentrates it in the permanently installed base. The base contains pre-installed receiver tubes, mounting brackets, and fastening hardware that remain on the vehicle. Accessories simply need to engage with these pre-positioned mounting points, eliminating the need for users to carry tools or perform complex fastening operations when swapping accessories.
Solution Approach 2:
All complex fastening hardware, mounting brackets, and structural components are pre-installed on the base during manufacturing or initial installation. When users want to change accessories, they simply need to attach the new accessory to the pre-prepared mounting points on the base, which already contain the necessary fasteners and structural support, making the process tool-free and simple.
4Adaptability or versatility
If multiple conventional hitch attachments are collected for different activities, then all activity needs can be met, but the collection becomes prohibitively expensive and difficult to store
Solution Approach 1:
The system employs a single universal base attachment that can accommodate multiple different accessory types through standardized mounting interfaces. Instead of needing separate complete attachment systems for grilling, biking, cargo transport, and other activities, the user has one base that can mount various accessories as needed, dramatically reducing the total number of components to store and manage while maintaining full activity coverage.
Solution Approach 2:
The accessory attachments are designed to nest or stack when not in use, fitting within or alongside each other to minimize storage space. The modular design allows smaller accessories to be stored within or adjacent to larger ones, and the system can be collapsed or disassembled to fit in compact spaces such as vehicle trunks or garages, making storage of multiple accessories practical and space-efficient.
