Rotary Display Hook With Bayonet Mounting Against Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional merchandise display hooks are not securely mounted to support walls, leading to accidental detachment during item removal and a difficult mounting process.
Innovation Solution
A bayonet-type mounting configuration where the hook is inserted through an enlarged opening in the support wall from the rear and rotated to secure it, utilizing a base with parallel walls and a central recess for alignment and rotation, ensuring the hook is locked in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting with small holes and protrusions is used, then the mounting process is simple, but the hook becomes accidentally detached during item removal
Solution Approach 1:
The hook base is designed to be inserted in a neutral orientation and then rotated 90 degrees to lock into place. This dynamic transformation from insertable state to locked state provides both ease of installation and secure mounting, resolving the contradiction between mounting security and mounting ease.
Solution Approach 2:
The base is segmented into a first wall with opening-forming sections and a second wall, allowing the opening to be formed by the sections themselves rather than requiring a pre-drilled hole. This segmentation enables simple installation while achieving secure mounting through the rotation mechanism.
2Reliability
If conventional mounting with friction engagement is used, then the mounting process is simple, but the hook may become accidentally detached
Solution Approach 1:
The mounting mechanism uses a simple rotational motion to transform the base from an insertable configuration to a locked configuration. This dynamic approach provides secure mounting without complex mechanisms, as the security is achieved through the geometric transformation rather than additional locking components.
Solution Approach 2:
The base structure itself provides the locking mechanism through its geometry. The first wall sections form the opening and the rotation of the base relative to the support wall creates the secure engagement automatically, without requiring separate locking devices or complex mechanisms.

AI summary
A hook is provided for a merchandise display including a support wall having an opening. The hook includes a base. The base includes a first wall and a second wall. The base walls are substantially parallel to each other and spaced from each other by a distance at least as great as the thickness of the support wall. The hook extends from the first wall and is adapted to retain one or more merchandise items. The first wall has a central portion and oppositely directed, substantially coplanar sections extending from the central portion. The first wall is adapted to be inserted through the support wall opening from behind the support wall such that the support wall is situated between the first wall and the second wall. The hook is then rotated relative to the support wall to secure the base of the hook to the support wall.
