Solution Overview

Problem

Existing solutions for damping forces in wooden buildings are costly and require multiple devices, necessitating a more cost-efficient and compact solution that can effectively damp forces in multiple directions.

Innovation Solution

A damping bracket comprising anchoring plates with cylindrical channel elements and radial and axial damping elements, connected by a connection member, which allows for damping forces in both radial and axial directions using a single device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate damping devices are used to damp forces in different directions, then damping effectiveness is improved, but device complexity and cost increase

Engineering Contradiction:
Improvedamping effectivenessVSAvoidnumber of devices
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple damping functions into a single integrated bracket assembly. The bracket includes both radial damping elements (first and second damping elements) and axial damping elements (third and fourth damping elements) unified within one structural component that connects two structural members. This merging eliminates the need for multiple separate damping devices while maintaining comprehensive damping effectiveness in both radial and axial directions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bracket is designed as a universal component that performs multiple damping functions simultaneously. It provides radial damping through the first and second damping elements, axial damping through the third and fourth damping elements, and structural support all within a single device. This multi-functionality allows one bracket to replace what would traditionally require multiple specialized damping devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate damping devices are used to damp forces in different directions, then damping effectiveness is improved, but material consumption increases

Engineering Contradiction:
Improvedamping effectivenessVSAvoidmaterial consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent merges multiple damping elements into a single integrated bracket structure. The first damping element, second damping element, third damping element, and fourth damping element are all unified within one bracket assembly, reducing the total material consumption compared to using four separate damping devices. The shared structural components and connection elements further reduce overall material usage.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple separate damping devices are used to damp forces in different directions, then damping effectiveness is improved, but installation complexity increases

Engineering Contradiction:
Improvedamping effectivenessVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple damping elements and structural components into a single pre-assembled bracket unit. This integration simplifies installation significantly, as the entire damping assembly can be installed as one component rather than requiring the coordination and assembly of multiple separate devices. The bracket includes all necessary damping elements (radial and axial) and structural members unified in a single installable unit.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present invention relates to abracket for damping forces between a wall and a floor of a building. The bracket comprises a first and a second anchoring plate, at least two cylindrical channel elements connected to the first anchoring plate and at least one cylindrical channel element connected to the second anchoring plate. The bracket is characterized by a radial damping element inside each cylindrical channel element, the radial damping element(s) thereby providing damping of radial forces between the anchoring plates, and at least one axial damping element damping axial forces between the anchoring plates, wherein the connection member is extending though a through-hole of each radial damping element and a through-hole of said axial damping element. Thus, a bracket according to the present invention permits damping in at least two substantially different directions, preferably in a radial direction and an axial direction.
