Magnetic Hook Closure for Easier Element Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hooks require users to manually guide elements through an opening while overcoming adhesive forces, which can be cumbersome, especially when the closure element is difficult to grasp or manipulate.
Innovation Solution
The hook incorporates an adhesion element, such as a magnet, positioned adjacent to the opening, allowing elements to be easily aligned and inserted with a straight movement, and a rotatable closure element that opens via a moment of force applied during insertion, simplifying the process without requiring manual manipulation of the closure element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnet is incorporated into the hook to secure an element, then the element is held firmly, but the element cannot be easily inserted or removed
Solution Approach 1:
The magnetic adhesion system is divided into two separate locations: a first magnet in the hook body for securing the element, and a second magnet on the closure element for guiding it during insertion. This segmentation allows the insertion path to be magnetically guided while the final securing position remains firmly held by the first magnet.
Solution Approach 2:
A second magnet is introduced as an intermediary component on the closure element. This intermediary magnet creates a magnetic bridge that guides the element into the hook during insertion, mediating between the user's manual insertion action and the hook's magnetic retention force, thereby reducing the effort needed to overcome adhesion.
2Reliability
If the closure element is positioned to close the opening effectively, then security is improved, but the element becomes difficult to grasp and manipulate
Solution Approach 1:
The second magnet on the closure element acts as a manipulative intermediary that users can grasp and manipulate separately from the closure element's functional closing action. This allows users to handle the magnetic component easily while the closure element itself maintains its secure closing function.
Solution Approach 2:
The magnetic interaction is positioned in a different spatial dimension than the closure element's mechanical closing action. The second magnet is arranged to interact with the element during insertion approach, while the closure element's closing function operates independently, separating the manipulation dimension from the securing dimension.
3Reliability
If adhesive force is increased to secure the element firmly, then retention is improved, but more force is required to insert the element
Solution Approach 1:
The adhesive (magnetic) force is segmented into two functional zones: a guiding zone with the second magnet that provides mild attraction during insertion, and a retention zone with the first magnet that provides strong attraction for securing. This segmentation allows firm retention while reducing insertion force requirements.
Solution Approach 2:
Different magnetic strengths and positions are applied locally: the second magnet is positioned to create a gentle guiding field along the insertion path, while the first magnet is positioned and sized to create a strong retention field at the final securing position. This local differentiation of magnetic quality resolves the force contradiction.
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
This design simplifies the insertion process by allowing elements to be easily aligned and moved into the hook using a straight movement, reducing the effort required to overcome adhesive forces and facilitating the use of larger or harder-to-grasp elements.
Implementation Method 1
The hook comprises an adhesion element arranged on the closing element... The hook can include a first Velcro element as an adhesion element, and the element can include a second Velcro element. The hook can include an adhesive surface as an adhesive element.
Implementation Method 2
The adhesion element is arranged in a hook section, from which hook section an element detachably held on the adhesion element can be moved into the interior of the hook by an essentially straight movement.
Implementation Method 3
a rotatable closure element that opens via a moment of force applied during insertion
