Dual-Suction Door Hook With Foldable S-Hook Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction-mounted hooks are limited in their ability to adjust orientation relative to the mounting surface, which restricts their versatility in holding objects of varying sizes and weights, and they often require larger packaging due to fixed hook orientations.
Innovation Solution
A suction-mounted door hook design featuring two suction cups with recesses and an S-shaped hook that can be positioned either perpendicular or parallel to the mounting surface, utilizing projections and recesses to securely engage the hook in both orientations, allowing for easy adjustment and secure holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hook is designed to be substantially perpendicular to the mounting surface, then the hook can securely hold objects, but the package size increases and requires more shelf space
Solution Approach 1:
The hook is designed to be movable relative to the suction cup, allowing it to transition between a perpendicular position for secure object holding and a parallel position for compact packaging. This dynamic reconfiguration enables the same structure to serve both functional and storage requirements efficiently.
2Device complexity
If a single suction cup is used, then the device structure is simpler, but the weight holding capacity is limited
Solution Approach 1:
Two suction cups are combined with a single S-shaped hook to create a unified mounting system. The hook connects both suction cups, distributing the load and increasing overall weight holding capacity while maintaining relatively simple device structure.
3Strength
If the hook is rigid and the suction cup is flexible, then the hook maintains structural integrity, but the hook moves relative to the suction cup under lateral forces
Solution Approach 1:
The device is segmented into distinct rigid (hook) and flexible (suction cup) components with defined interaction interfaces. The recesses and projections create controlled engagement points that allow the rigid hook to maintain structural integrity while the flexible suction cup absorbs lateral movements, reducing relative displacement between components.
4Force
If two suction cups are used to increase weight capacity, then more weight can be held, but the hook size and package volume increase
Solution Approach 1:
The S-shaped hook is designed to nest within the openings defined by the suction cups and loop portions when in the parallel position. This nested configuration allows the two-suction-cup assembly to maintain high weight capacity while occupying minimal space during packaging and storage.

AI summary
A suction mounted door hook has two suctions cups and a hook connected to the two suction cups. Each suction cup has a cup portion and a loop portion attached to the cup portion such that the loop portion and a surface of the cup portion define an opening. There is a recess on that surface of the cup portion and a pair of spaced apart loop projections on the top surface and preferably on the bottom surface of the loop portion that have a recess between them which is opposite the recess in the cup portion. The hook has an S-shaped body and two legs, one leg being within the opening of each suction cup. The hook can be in either an extended position or a folded position. Surfaces and projections on the hook mate with the recesses in the suction cups to hold the hook in either position.
