Nested Rotatable Luggage Hook for Multi-Item Suspension Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage hooks are inconvenient and difficult to use, particularly when handling multiple items of baggage, as they often require multiple hooks, fixed directionality, or complex fastening mechanisms that compromise stability and ease of use.
Innovation Solution
A luggage hook design featuring a base with a belt for attachment, a primary hook member with a cylindrical neck and rotatable primary hook body, and a secondary hook member with a rotatable secondary hook body that aligns to block the primary hook's opening, allowing for secure and stable suspension of multiple items without requiring multiple hooks or complex direction adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single hook part is used, then the structure is simple, but only one item of baggage can be hung
Solution Approach 1:
The secondary hook member is nested within the primary hook member, with the secondary neck section fitting inside the primary neck section. This nesting arrangement allows two hook bodies to occupy the same attachment location without requiring multiple separate attachment points, thereby maintaining structural simplicity while enabling multiple baggage items to be suspended simultaneously
Solution Approach 2:
The hook is divided into two independent functional segments: the primary hook member for general use and the secondary hook member for additional capacity. Each hook member can independently suspend baggage items, and they can be positioned at different rotational angles to accommodate multiple bags without interfering with each other
2Stability of the object's composition
If the hook part is fixed in place, then the structure is stable, but the direction from which baggage is hung becomes fixed
Solution Approach 1:
The hook members are designed with rotational capability around the vertical axis, transforming the fixed static structure into a dynamic one. The primary and secondary hook bodies can rotate independently to different angular positions, allowing baggage to be hung from various directions while maintaining structural stability through the attachment mechanism
3Adaptability or versatility
If the hook part rotates around the axis of rotation, then directional flexibility is improved, but baggage stability deteriorates
Solution Approach 1:
The rotational movement is segmented and distributed between two independent hook members rather than one. The primary hook member provides the main suspension function with its rotational capability, while the secondary hook member, positioned at a different angle, provides additional stability and can independently support baggage, thereby maintaining overall baggage stability even as the primary hook rotates for directional flexibility
4Device complexity
If hook-and-loop fasteners are used, then the structure is simple, but the user must check the front and rear of the fasteners every time they are wrapped around
Solution Approach 1:
The belt fastening system is designed to be self-aligning and self-securing. The belt wraps around the attachment location and fastens automatically without requiring the user to check front and rear positions or perform complex manipulation. The design eliminates the need for user verification steps, allowing quick and easy attachment even when handling multiple baggage items or in hurried situations
