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 theft issues, while also being complicated to attach and detach.
Innovation Solution
A modular carrier rack system integrated into the 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, allowing for secure and versatile transport of recreational equipment without damaging the vehicle.
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 achieved, but the system becomes cumbersome, heavy, and difficult to store when not in use
Solution Approach 1:
The carrier bar is designed to be received within a receiving unit that is integrated into the vehicle body. When not in use, the carrier bar nests inside the receiving unit, eliminating the need for separate storage and reducing system complexity. This nesting arrangement allows the system to transition between a compact stored state and an extended operational state.
Solution Approach 2:
The receiving unit is integrated directly into the vehicle body structure, merging the mounting function with the vehicle's existing framework. This integration eliminates the need for separate external mounting systems and reduces overall system complexity while maintaining cargo transport capability.
2Adaptability or versatility
If traditional carrier rack systems are attached to the roof or external mounts, then cargo transport is enabled, but the systems create wind resistance and make it difficult to access the trunk or doors
Solution Approach 1:
The carrier bar is extracted from the vehicle body only when needed for cargo transport. During normal operation, the receiving unit remains integrated into the vehicle body without interfering with trunk or door access. The carrier bar can be deployed externally when required, providing cargo transport capability without permanently obstructing vehicle access points.
3Adaptability or versatility
If carrier rack systems are attached to bumpers or external structures, then cargo transport is achieved, but the systems may scratch and damage the vehicle when attached and used
Solution Approach 1:
The receiving unit is integrated into the vehicle body with protective features that prevent direct contact between external mounting components and the vehicle's painted surfaces. This integration ensures that the mounting structure is protected from scratching or damaging the vehicle during attachment and use, addressing the harmful effect before it can occur.
4Adaptability or versatility
If traditional carrier rack systems are designed for universal attachment, then adaptability to different vehicles is improved, but the systems become heavy and difficult to attach and detach
Solution Approach 1:
The carrier rack system is segmented into two main components: a receiving unit that is integrated into the vehicle body and a separate carrier bar that can be attached or removed. This segmentation allows the receiving unit to remain lightweight and vehicle-specific, while the carrier bar provides the necessary cargo transport functionality. The segmented design reduces overall system weight compared to traditional universal mounting systems.
