Carrier Plate With Alternating Protrusions For Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier plates for floor, wall, or ceiling structures do not effectively decouple from supporting surfaces, leading to inadequate support and sound insulation.
Innovation Solution
A carrier plate with alternately protruding truncated cone or pyramid-shaped protrusions on both sides of a film-like plastic plate, arranged in rows and columns with crosspieces along diagonals, providing a high number of nubs for increased contact surface and decoupling performance, along with an adhesion-enhancing layer for improved bonding and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If protrusions are formed on only one side of the film-like plate, then the structure is simpler to manufacture, but the contact surface area and decoupling performance are reduced
Solution Approach 1:
The invention transitions from single-sided protrusion formation to double-sided protrusion formation, utilizing the third dimension (through-thickness direction) to increase contact surface area. Protrusions are formed alternately from both sides of the film-like plate, effectively doubling the contact interface with the supporting surface while maintaining the same planar footprint.
Solution Approach 2:
The film-like plate is segmented into multiple regions with protrusions distributed across both surfaces. The protrusions are arranged in an alternating pattern where those from one side complement those from the other side, creating a distributed contact network that enhances decoupling performance across the entire plate area.
2Force
If the number of protrusions is increased to enhance load capacity, then the contact surface area increases, but the manufacturing complexity and material requirements increase
Solution Approach 1:
By utilizing both sides of the film-like plate for protrusion formation, the invention effectively doubles the number of load-bearing contact points without increasing the planar complexity. The alternating arrangement from opposite sides creates a three-dimensional load distribution network that enhances force capacity while maintaining manageable manufacturing complexity.
3Area of stationary object
If protrusions are made with larger height to increase contact surface, then the decoupling performance improves, but the material consumption and structural rigidity increase
Solution Approach 1:
The total contact surface area is achieved through segmentation into numerous small protrusions distributed across both sides of the plate rather than a few large protrusions. This segmentation allows the contact interface to be distributed throughout the thickness of the film-like plate, reducing the need for excessive material while maintaining effective decoupling surface area.
