Rotating Partition Hook Structure for Heavy Bags and Door Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door hooks are inadequate for securely holding heavy bags of various sizes and weights, often causing doors to open inadvertently, especially in public restrooms with poorly constructed hooks, and there is a need for a device that provides both support and security for bags while keeping doors closed.
Innovation Solution
A versatile attachable partition hook with a door closed keeper, featuring a first hook with a stem and curvature, a joint, and a second hook with a socket, designed to rotate on a single axis, allowing secure attachment to any surface and preventing door opening under weight, with extension arms for stability and a locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hook is used to hold heavy bags on door partitions, then the bag can be suspended off the floor, but the door may open inadvertently due to the weight of the bag
Solution Approach 1:
The patent combines two separate functions into one device: a hook for suspending bags and a door-closing mechanism. The L-shaped configuration integrates the hanging function (vertical stem) with the door-closing function (horizontal arm that engages with the door edge), allowing simultaneous achievement of bag support and door securing.
Solution Approach 2:
The solution transitions from a single-point hanging mechanism to a two-dimensional L-shaped structure. The vertical dimension handles bag suspension while the horizontal dimension provides door-closing capability, effectively using spatial expansion to resolve the contradiction between supporting weight and maintaining door closure.
2Adaptability or versatility
If existing door hooks are used, then bags can be hung temporarily, but they cannot securely hold heavy bags of various sizes and weights
Solution Approach 1:
The device is designed to perform multiple functions: it can hook onto door partitions, support bags of various weights, and simultaneously act as a door-closing mechanism. The L-shaped structure with adjustable positioning capabilities makes it universally applicable to different bag sizes and door types, resolving the contradiction between versatility and strength.
3Reliability
If a secure door-closing mechanism is added to the hook, then door security is improved, but the device complexity increases
Solution Approach 1:
The device is segmented into two distinct functional parts: the vertical stem for hanging bags and the horizontal arm for door closure. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity. The modular L-shaped design avoids complex mechanisms by using basic geometric forms with clear functional separation.

AI summary
An attachable partition hook operable to support a carrying parcel includes a first hook having a first stem and a first curvature. The partition hook includes a joint affixed to an end of a said first stem. The partition hook includes a second hook having a second stem, a second curvature, and a hollow socket affixed to the end of the second stem, wherein the hollow socket is configured to retain the joint of the first stem. The partition hook includes a second hook having a second stem, a second curvature, and a hollow socket affixed to the end of the second stem, wherein the hollow socket is configured to retain the joint of the first stem. The partition hook includes a first hollow retaining portion positioned on the stem of the first hook, wherein the hollow retaining portion comprises of a first extending arm. The partition hook includes a second hollow retaining portion positioned on the end of the first curvature of the second hook, wherein the hollow retaining portion comprises of a second extending arm. Additionally, the joint of the first hook is coupled to the socket of the second hook, wherein the first hook and the second hook are positioned to be oriented perpendicular to each other and operable to rotate on a single axis.
