Vehicle Luggage Hook Structure That Protects the Bezel Under Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage hooks in vehicles often fail due to cracking or breakage of the bezel when a load is applied, as the load is transmitted directly to the bezel from the hooking portion.
Innovation Solution
A luggage hook design featuring a rotatable hook with a metal stopping portion attached to the frame, which redirects the load from the bezel, enhancing load resistance by allowing the hook to stop rotation at a use position and utilizing a spring and rotary damper for stable deployment and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hook is attached around the bezel frame, then the hook can be deployed and retracted smoothly, but the bezel frame experiences cracking or breakage when load is applied
Solution Approach 1:
The invention extracts the load-bearing function from the bezel frame by introducing a separate stopping portion that is joined directly to the interior portion. The stopping portion assumes the role of receiving and distributing the load, while the bezel frame retains only its original function of guiding and constraining the hook's rotation path.
Solution Approach 2:
The stopping portion acts as an intermediary element between the hook and the interior portion. Instead of the load being transmitted directly from the hook through the bezel frame to the interior portion, the stopping portion intercepts the load at the hook's rotation stop position and transfers it directly to the interior portion, breaking the harmful load path through the bezel.
2Strength
If the hook stops rotation at the use position, then load is redirected from the bezel to the frame, but the hook rotation path must be precisely controlled
Solution Approach 1:
The stopping portion is designed to work passively with the hook's rotation mechanism. As the hook rotates to its deployed position, it naturally contacts the stopping portion which provides a mechanical stop. The system self-regulates the rotation position through this mechanical interaction without requiring external control systems or complex positioning mechanisms.
Solution Approach 2:
The stopping portion is pre-positioned and joined to the interior portion before the hook is deployed. This preliminary positioning ensures that when the hook rotates to its use position, the load is already directed to the correct stopping point on the interior portion, eliminating the need for dynamic adjustment during operation.
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
The design effectively distributes the load to the frame, reducing stress on the bezel and enhancing load resistance while maintaining a flush appearance and smooth operation.
Implementation Method 1
a spring configured to bias the hook to rotate in the deployment direction with respect to the interior portion
Implementation Method 2
a rotary damper configured to damp rotation of the hook in the deployment direction with respect to the interior portion

AI summary
A luggage hook provided in an interior portion of a vehicle includes a hook configured to be coupled to the interior portion so as to be rotatable about an axis extending in a lateral direction of the vehicle, a bezel including a frame configured to be fixed to the interior portion and to be attached around the hook, and a metal stopping portion joined to the frame of the interior portion and configured to, at a use position, stop rotation of the hook in a deployment direction protruding from the bezel. A direction in which the rotation of the hook is stopped by the stopping portion is the same as a rotation direction in which the hook is pressed about the axis as an object is hooked at the use position.
