Vehicular Interior Utility Part Assembly With Pin-Coupled Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting assemblies for utility parts in vehicular interiors, such as sunshades, are labor-intensive and time-consuming due to the requirement of pre-drilled screw holes, leading to instability in the mounting process.
Innovation Solution
A utility part assembly featuring a vehicular interior part with first and second mounting holes and corresponding coupling pins and holes, allowing for easy and stable mounting of utility parts by inserting coupling pins through mounting holes, eliminating the need for screws and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw holes are provided in the frame garnish to mount the hook member, then the hook member can be fixed to the frame garnish, but it requires labor and time to fix the hook member with screws, making the mounting process difficult
Solution Approach 1:
The mounting system is divided into separate components: the frame garnish with mounting holes and the utility part with coupling pins. This segmentation allows the utility part to be mounted without requiring pre-drilled screw holes in the frame garnish, simplifying the mounting process while maintaining stability through the pin-coupling mechanism
Solution Approach 2:
Coupling pins serve as intermediary elements that connect the utility part to the frame garnish. Instead of directly screwing the utility part into the frame garnish, the coupling pins are inserted through mounting holes to provide a stable connection, eliminating the need for screws and reducing mounting complexity
2Reliability
If screw holes are provided in the vehicular interior part, then utility parts can be mounted to the vehicular interior part, but it is not easy to mount the utility parts stably due to the complexity of the screw mounting process
Solution Approach 1:
The screw fastening mechanism is extracted from the mounting system and replaced with a simpler pin-coupling mechanism. The coupling pins are inserted through mounting holes in the vehicular interior part to secure the utility part, eliminating the need for screws and reducing the overall complexity of the mounting process while maintaining mounting stability
Solution Approach 2:
Instead of using threads that require rotational insertion and tightening, the mounting system uses straight coupling pins that are simply inserted through holes. This inverts the traditional screw mounting approach, making the process easier and more straightforward while achieving stable mounting

AI summary
A utility part assembly includes a vehicular interior part and a utility part. The vehicular interior part has a first surface and a second surface that is opposite to the first surface and has a first mounting hole and a second mounting hole. The utility part includes a first member provided on the first surface and a second member provided on the second surface. The first member has a first coupling pin and one of a second coupling pin and a first coupling hole, and the second member has a coupling portion that is coupled to the first coupling pin and another one of the second coupling pin and the first coupling hole. The first coupling pin is inserted through the first mounting hole and coupled to the coupling portion, and the second coupling pin is inserted through the second mounting hole and coupled to the first coupling hole.
