Magnetic Mannequin Limb Connection With Drop-Out Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection systems for mannequins, particularly magnetic ones, suffer from accidental detachment of limbs during dressing or undressing, leading to complete separation and difficulty in reattachment.
Innovation Solution
A connection system featuring a fail-safe design with a first projection and second projection that engage to prevent complete separation, combined with a magnetic connection for easy detachment and reattachment, utilizing a pin and opening configuration with optional fastening means like metal strips for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnetic connection system is used to attach the limb to the torso, then the limb can be easily detached and reattached without wear, but the limb may accidentally detach and fall completely from the torso
Solution Approach 1:
The connection system is divided into two functional segments: a magnetic connection mechanism for easy attachment/detachment and a fail-safe projection mechanism for preventing complete separation. The pin is segmented with a first projection for magnetic engagement and a second projection for fail-safe engagement, allowing each segment to perform its specific function independently
Solution Approach 2:
The fail-safe device with the second projection acts as a pre-prepared safety mechanism that engages before complete separation can occur. If the magnetic connection fails, the second projection is already positioned to engage with the torso connection element, cushioning against the harmful effect of complete limb separation
2Reliability
If a strong magnet is selected to prevent accidental detachment, then the limb remains securely attached, but the limbs can only be separated with great difficulty or not at all
Solution Approach 1:
The connection system transitions from a static strong magnetic bond to a dynamic multi-stage release mechanism. The magnetic connection provides initial secure attachment, but the fail-safe projections are designed to disengage at specific moments during the detachment process, allowing controlled separation without requiring excessive force
3Device complexity
If simple plug-in connections or bayonet locks are used to attach the limb, then the structure is simple, but the limb can accidentally detach during dressing or undressing
Solution Approach 1:
The invention merges multiple connection mechanisms into a single integrated system: the magnetic connection element combines the simplicity of plug-in connections with the security of magnetic holding, while the fail-safe projections combine mechanical engagement with the redundancy needed to prevent accidental detachment during dressing operations
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
Ensures the limb remains securely attached to the torso during normal use while allowing easy detachment and reattachment without wear, preventing uncontrolled falling and facilitating dressing and undressing.
Implementation Method 1
the limb connecting element can be fastened to the torso connecting element by means of a magnetic connection. The magnetic connection creates a possibility of attaching the limb connecting element to the torso connecting element, which can be actuated as often as required and without wear.

AI summary
The invention relates to a connection system (56) for a manikin, with which a limb of the manikin can be detachably connected to a torso of the manikin. The connection system (56) represents the interface between the limb and the torso. In the fully fastened position, a limb-side limb connection element (14) is held magnetically on a torso-side torso connection element (26). If the magnetic connection is released, a first projection (62) in the area of a first opening (28) of one of the connecting elements (26) is gripped behind by a second projection (64) which is attached to a first pin (16) of the other connecting element (14 ) is arranged or formed. The first projection (62) and the second projection (64) thereby constitute a fail-safe device (60) which prevents the limb from falling when the magnetic connection is released.
