Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction dampers, such as steel hysteretic dampers, face limitations in deformation path and buckling issues, making them unsuitable for large and tall structures, and are difficult to maintain due to their large size and hidden inner workings.
Innovation Solution
A construction damper with a spatially structured thrust damping part featuring multiple rung-like transverse beams in different alignments, which increases stability and maximum force absorption, allowing for adjustable deformation paths and easy maintenance, by arranging additional transverse beams in parallel planes and using metal materials like steel for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional steel hysteretic dampers with single alignment transverse beams are used, then the structure is simpler and easier to manufacture, but the buckling resistance and deformation path are limited
Solution Approach 1:
The patent transitions from a single-plane ladder structure to a spatial three-dimensional structure by adding transverse beams in a second alignment that deviates from the first alignment. This dimensional change creates a spatial configuration that provides buckling resistance in multiple directions while maintaining structural efficiency
Solution Approach 2:
The thrust damping part is divided into multiple segments with transverse beams arranged in different alignments, creating a modular spatial structure that can be manufactured and assembled in manageable sections while achieving superior overall stability
2Reliability
If conventional steel hysteretic dampers with large dimensions are used, then the necessary damping effect can be achieved, but the installation space requirement increases and replacement cost increases
Solution Approach 1:
The patent changes the structural parameters by introducing spatial configuration with multiple alignments of transverse beams, which increases the damping capacity per unit length and allows for more compact damper designs that fit within limited installation spaces
Solution Approach 2:
The damper employs a composite structural system combining longitudinal beams with transverse beams in multiple alignments, creating a integrated spatial framework that achieves high damping efficiency in a compact form factor
3Stability of the object's composition
If conventional steel hysteretic dampers with hidden inner workings are used, then the structural integrity is maintained, but the condition assessment and maintenance difficulty increase
Solution Approach 1:
The spatial structure with its open ladder-like configuration in multiple alignments allows the damper to maintain structural integrity while being inherently observable, enabling condition assessment without disassembly and facilitating easy maintenance access to internal components
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 provides improved buckling behavior and increased maximum force absorption, enabling effective damping in large structures while being more compact and easier to maintain, overcoming the limitations of conventional steel hysteretic dampers.
Implementation Method 1
damping is effected in such a way that a normal force is introduced into one of the two longitudinal beams, which is transmitted in a damped manner to the other longitudinal beam by the transverse beams deformed by the thrust force. If a pendulum motion occurs, the normal force introduced into the longitudinal beam will alternately be a tensile or a compressive force, which is dissipated by the plastic deformation of the interposed transverse beams
Implementation Method 2
Here, too, a load-deformation curve with the course of a hysteresis loop is produced
