Nested Rotating Luggage Hook Design for Multi-Bag 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 hanging directions, and can lead to instability due to the center of gravity of the baggage, and the need to manage hook-and-loop fasteners can be cumbersome.
Innovation Solution
A luggage hook design featuring a base with a belt that wraps around a handlebar, a primary hook member with a cylindrical neck and upward-opening hook body, and a secondary hook member that rotates relative to the base, allowing for overlapping positions without interference, and utilizing hook-and-loop fasteners for secure attachment, enabling easy handling and stability.
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 patent implements a nested hook configuration where a second hook part is positioned inside the first hook part. The second hook part has a smaller opening than the first hook part, allowing it to be nested within. This nested structure enables multiple items of baggage to be hung simultaneously on the same hook assembly, resolving the contradiction between structural simplicity and multi-bag capacity.
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 patent makes the hook parts rotatable around the vertical axis of the attaching part, transforming the fixed hook design into a dynamic one. This rotation capability allows the hook to adapt to different hanging directions and positions, enabling users to hang baggage from various angles while maintaining stable attachment to the handlebar.
3Device 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 patent applies different colors to the front and rear surfaces of the hook-and-loop fasteners. The front surface is colored differently from the rear surface, providing visual feedback to users about the correct orientation and wrapping direction. This color differentiation eliminates the need for users to check the front and rear of the fasteners manually, significantly improving ease of operation while maintaining the simplicity of the hook-and-loop attachment mechanism.
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 improves ease of use by allowing multiple items to be hung securely without needing multiple hooks, providing stability through adjustable hook positions and simplifying the attachment process, even when handling multiple bags quickly.
Implementation Method 1
a belt (81) attached to the base (20) for wrapping around the attachment location
Implementation Method 2
a first fastening part (81e) having a loop surface and a second fastening part (81e) having a hook surface
