Furniture Suspension Hook With Auto-Locking Securing Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices for hanging furniture on walls require complex adjustments and additional material for secure attachment, limiting ease of use and flexibility, especially when detaching or repositioning furniture.
Innovation Solution
A suspension device with a pivoting support element and a deflectable securing element that automatically locks into place upon reaching the suspended position, utilizing energy accumulation or gravity for secure attachment and allowing for easy detachment without tilting, and adjustable for various furniture configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If projections are arranged on the support element to prevent unintentional detachment, then security against detachment is improved, but the device complexity and material requirements increase due to the need for additional protruding lower fold on the counter bearing
Solution Approach 1:
The securing element is extracted from the support element and implemented as a separate, deflectable component that can be engaged by the counter bearing. This separation allows the securing mechanism to be more flexible and less complex, as the securing element can deflect during assembly and then lock into position without requiring complex interlocking geometries between the support element and counter bearing.
Solution Approach 2:
The securing element changes its spatial configuration through deflection - it transitions from a retracted position during assembly to an engaged position that prevents detachment. This parameter change (position/orientation of the securing element) provides the security function without requiring additional permanent structural features on either the support element or counter bearing.
2Reliability
If projections are arranged at sufficient distance from the hook part to reach under the protruding lower fold, then security against detachment is improved, but the assembly time increases due to the need to pivot the furniture body against the wall
Solution Approach 1:
The securing element is pre-positioned on the support element in a retracted or accessible position before assembly. During the assembly process, it automatically engages with the counter bearing as the support element is pivoted into place, eliminating the need for separate securing actions or complex manual manipulation of projections and folds.
Solution Approach 2:
The securing element automatically engages with the counter bearing through its deflectable nature and proper positioning. As the support element is installed, the securing element passively locks into position without requiring active manipulation by the installer, thereby reducing assembly time and complexity.
3Ease of operation
If the support element is pivoted to the parked position away from the wall, then accessibility is improved, but security against detachment is lost since the projections no longer reach under the protruding lower fold
Solution Approach 1:
The securing element is designed to be deflectable and dynamically positioned relative to the support element. This allows it to maintain engagement with the counter bearing across different positions of the support element, including the parked position away from the wall. The securing element can flex or adjust its position to continue providing security while the furniture is in various configurations.
4Reliability
If a protruding lower fold is added to the counter bearing for the projections to engage under, then security against detachment is improved, but the material costs and manufacturing complexity increase
Solution Approach 1:
The security function is extracted from the counter bearing structure and implemented through a separate securing element on the support element. This eliminates the need for the counter bearing to have complex protruding lower folds or specialized geometries, allowing the counter bearing to remain a simple, easily manufactured component while the securing element provides the necessary security function.
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
Enables secure and easy hanging of furniture without the need for complex adjustments, allows for secure attachment even when partially deployed, and facilitates easy detachment without tilting, reducing assembly time and material costs while accommodating different furniture types and positions.
Implementation Method 1
a securing element (120) which is arranged on the support element (101) to prevent an unintentional detachment of the support element (101) from the counter bearing (7), wherein the securing element (120) is deflectably arranged on the support element (101)
Implementation Method 2
The return pivoting force can be introduced by an energy accumulator
Implementation Method 3
or by the effect of gravity on the movably mounted securing element
Implementation Method 4
or also possible to design the securing element (120) as a leaf spring element, so that the pivoting back takes place solely through the return bending of the leaf spring
