Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening solutions for blinds do not effectively decouple structure-borne noise, leading to noise pollution in buildings due to the transmission of vibrations from blind components to the wall or ceiling.
Innovation Solution
A fastening device comprising a carrier, a holding element, and an elastic insulating element that supports the blind via a connecting element, which decouples structure-borne noise by increasing the distance between the holding element and the carrier when the blind is mounted, preventing sound bridges and reducing noise emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard contact surfaces are used between the blind and the wall for fastening, then the fastening is simple and reliable, but structure-borne noise is transmitted severely
Solution Approach 1:
The patent introduces an elastic insulating element as an intermediary between the carrier and the holding element. This element serves dual purposes: it provides sound insulation to prevent structure-borne noise transmission while maintaining the mechanical connection reliability through its elastic properties that allow controlled deformation under load.
Solution Approach 2:
The elastic insulating element functions as a flexible component that decouples the rigid connection between the blind and the wall. Its elastic nature allows it to deform under the weight of the blind while maintaining contact, creating a flexible connection that breaks sound bridges without compromising fastening reliability.
2Ease of manufacture
If the blind is fastened directly to the wall or ceiling, then the mounting is simple, but structure-borne noise from blind components is transmitted to the building
Solution Approach 1:
The elastic insulating element acts as a mediator that is easily integrated into the existing fastening structure. It requires no complex installation procedures - simply positioning it between the carrier and holding element during assembly provides both noise insulation and maintains the simplicity of the mounting process.
3Object-generated harmful factors
If an elastic insulating element is introduced to decouple structure-borne noise, then noise transmission is reduced, but the fastening device complexity increases
Solution Approach 1:
The fastening device is segmented into distinct functional components: the carrier for mounting to the building, the elastic insulating element for noise decoupling, and the holding element for securing the blind. This segmentation allows each component to be optimized independently while maintaining overall simplicity - the insulating element is just one additional component that provides noise reduction without complicating the other fastening functions.
4Ease of operation
If the connecting element passes through the insulating element with play, then assembly is facilitated, but precision of positioning is reduced
Solution Approach 1:
The insulating element's dimensions are specifically designed to provide appropriate play (clearance) for the connecting element. This parameter optimization allows easy assembly through the through-hole while the elastic nature of the insulating element compensates for any positioning variations, maintaining sufficient precision for functional requirements without compromising assembly ease.
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
The solution effectively reduces structure-borne noise transmission between the blind and the building part, minimizing noise pollution by maintaining a sound-insulated or sound-decoupled fastening of the blind, ensuring stable and flexible handling and assembly.
Implementation Method 1
the connecting element is led through a through-bore of an elastic, axially resilient insulating element arranged above the support. When the elastic insulating element is axially compressed, it exerts a tensile force on the holding element via the connecting element in the direction of the carrier.
Implementation Method 2
the force acting against the tensile force on the holding element is greater than the prestressing force. This has the effect that the prestressing force in the assembled state of the blind is overcome due to the load held by the holding element and the distance between the holding element and the carrier is thereby increased. Due to the lifting of the holding element from the support or due to the increase in the distance between the support and the holding element, structure-borne sound decoupling or structure-borne sound insulation is achieved between the blind and the part of the building.

AI summary
The present invention relates to a fastening device for a blind, comprising a support (12) intended to be attached to a building component (14, 15), and a retaining element (28) arranged below the support (12) and attached to it by means of a connecting element (44), wherein the retaining element (28) is intended to be connected to and support a blind. The connecting element (44) extends through the support (12) with clearance and through an elastic, axially resilient damping element (20) arranged above the support (12), wherein the damping element (20) is supported on the support (12) on one side and the connecting element (44) is supported on the damping element (20) on the other.When the blind is not mounted, the retaining element (28) is held on the support (12) by a tensile force acting on the retaining element (28) from the insulating element (20) via the connecting element (44) in the direction of the support (12) - directly or via an intermediate element (40) - under a prestressing force, wherein the prestressing force is less than a force acting on the retaining element (28) in the opposite direction to the prestressing force when the blind is attached to the retaining element (28) in the mounted state.
