Car Roof Luggage Rack Connecting Assembly Without Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process for mounting a car roof luggage rack involves complicated connections using fasteners like screws or bolts, which can damage the car roof structure and require significant modifications.
Innovation Solution
A connecting assembly comprising a luggage rack fixing support, a first connecting member, and a second connecting member, where the first engaging portion is an engaging slot and the second engaging portion is an engaging key, allowing for a simple and quick mounting process without fasteners, limiting movements to secure the luggage rack firmly on the car roof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seat belt assembly with a retractor, reel, and webbing is used, then the seat belt can be wound and paid out to restrain a passenger, but the assembly becomes complex and difficult to manufacture
Solution Approach 1:
The connecting assembly is divided into separate components: a first connecting assembly for the driver side and a second connecting assembly for the passenger side. Each assembly can be manufactured and installed independently, simplifying the overall system while maintaining full seat belt functionality on both sides.
Solution Approach 2:
The connecting assembly is designed to be universal and adaptable, with features that allow it to function in multiple configurations. The assembly can accommodate different seat belt routing requirements and can be used on both driver and passenger sides, reducing the need for multiple specialized components.
2Reliability
If a complex seat belt assembly with multiple components is installed in a car, then the seat belt can function properly, but the installation time and process become lengthy and complicated
Solution Approach 1:
By segmenting the seat belt system into separate first and second connecting assemblies, each side can be installed independently and more quickly. The modular design allows installation teams to work on both sides simultaneously without interference, significantly reducing total installation time.
Solution Approach 2:
The connecting assemblies are pre-configured and pre-assembled with all necessary components (retractors, reels, webbing) before installation in the vehicle. This preliminary preparation ensures that during vehicle assembly, the components are ready for quick installation without requiring complex on-site assembly procedures.
3Ease of manufacture
If a simplified connecting assembly is used, then the manufacturing process becomes easier, but the ability to restrain passengers effectively is reduced
Solution Approach 1:
The segmentation into first and second connecting assemblies maintains full restraint functionality by providing dedicated assemblies for driver and passenger sides, each with complete seat belt components including retractor, reel, and webbing, ensuring effective passenger restraint while simplifying manufacturing through modular production.
Solution Approach 2:
The universal design of the connecting assembly ensures that despite simplification, the assembly maintains full seat belt functionality including winding, payout, and restraint capabilities. The multi-functional design allows a single assembly type to serve both driver and passenger sides without compromising safety effectiveness.

AI summary
A car roof luggage rack connecting assembly. A side panel (10) is comprised, and the connecting assembly comprises a luggage rack fixing support (40), a first connecting member (20) and a second connecting member (30), wherein the luggage rack fixing support (40) is mounted on the side panel (10), and a slot (42) is formed between the luggage rack fixing support (40) and the side panel (10); the first connecting member (20) comprises a first transverse portion (21) and a first vertical portion (22) extending upward from a side of the first transverse portion (21), the first vertical portion (22) being provided with a first engaging portion (23), and the first transverse portion (21) being engaged in the slot (42); the second connecting member (30) is mounted on the side panel (10) and comprises a second vertical portion (32) provided with a second engaging portion (33) and vertically extending; and when the first engaging portion (23) is engaged with the second engaging portion (33), the first vertical portion (22) abuts against the second vertical portion (32) such that the first connecting member (20) is mounted between the second connecting member (30) and the luggage rack fixing support (40), and a car roof luggage rack (90) is mounted on a car by means of the first connecting member (20). A mounting process for the connecting member is easy and quick, and no fasteners are needed for fixation, thereby reducing changing of a car roof structure. Further disclosed is a car provided with the connecting assembly.
