Problem
The existing luggage ring assembly requires complex and time-consuming assembly processes, including welding, and is inflexible, making it difficult for end users to relocate or add additional luggage rings without professional assistance.
Innovation Solution
A luggage ring assembly with a quick release mechanism, comprising a resilient mounting member, a rotatable ring member, and a lever and cam assembly, allowing easy placement and repositioning without additional fixings or tools, and enabling secure attachment to various points on a body in white.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding and screw assembly are used to attach the luggage ring, then the connection strength is improved, but the assembly complexity and time increase
Solution Approach 1:
The luggage ring assembly is divided into separate components: a mounting member with aperture, a quick release fastener, and a ring member. This segmentation allows each component to be optimized independently and assembled through simple engagement rather than welding, reducing assembly complexity while maintaining connection strength
Solution Approach 2:
The quick release fastener acts as an intermediary component between the mounting member and the ring member. It provides a mechanical coupling solution that achieves strong connection without requiring welding operations, thereby reducing assembly complexity and time while maintaining sufficient connection strength
2Strength
If welding is used to attach the luggage ring, then the connection strength is improved, but the assembly time increases
Solution Approach 1:
The mounting member is pre-formed with an aperture during manufacturing, eliminating the need for post-manufacturing welding operations. The quick release fastener and ring member are designed to engage with this pre-prepared aperture, allowing rapid assembly without time-consuming welding processes while maintaining connection strength
Solution Approach 2:
The welding process is replaced with a mechanical engagement system consisting of the quick release fastener and aperture. This substitution eliminates thermal processes and complex assembly steps, dramatically reducing assembly time while providing sufficient mechanical connection strength for the application
3Strength
If the luggage ring is welded to a fixed location, then the connection strength is improved, but the adaptability decreases
Solution Approach 1:
The mounting member is designed with a resilient material that allows for dynamic adjustment and relocation. The aperture can be repositioned or new mounting points can be created without permanent welding, enabling the luggage ring to be moved or added at multiple locations while maintaining secure attachment through the quick release mechanism
4Adaptability or versatility
If additional back nuts are welded to relocate or add luggage rings, then the adaptability is improved, but the device complexity and cost increase
Solution Approach 1:
The mounting member is designed as a universal component that can be installed at multiple locations without requiring location-specific modifications. The same mounting member with aperture design can be used throughout the vehicle body, eliminating the need for different types of back nuts or specialized welding procedures for each mounting location, thereby reducing manufacturing complexity while maintaining relocation capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient and user-friendly assembly and repositioning of luggage rings, reducing manufacturing time and costs, and allowing secure attachment of luggage to different locations without the need for welding or specialized tools.
Implementation Method 1
said mounting member is made of a resilient material and adapted to mountingly engage with said aperture of said ring member. Use of a resilient material allows the ring member and/or quick release fastener to snap or interference fit with the mounting member
