Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tables with long legs or height-adjustable designs experience prolonged lateral vibrations due to external forces, such as being struck from the side, leading to prolonged disturbance.
Innovation Solution
Incorporating a vibration damping device between the connecting strut and fastening brackets, utilizing elastically yielding elements like elastic sleeves or mats to dampen lateral vibrations, reducing vibration amplitudes and duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid connection is used between the connecting strut and fastening brackets, then the structural strength is improved, but the vibration duration increases
Solution Approach 1:
The patent introduces a vibration damping element as an intermediary component between the connecting strut and fastening brackets. This element has a dual function: it provides mechanical connection to maintain structural strength while simultaneously damping vibrations through its viscoelastic properties, thus resolving the contradiction between strength and vibration duration
Solution Approach 2:
The vibration damping element is made from composite materials exhibiting viscoelastic behavior, combining elastic and viscous properties. This allows the material to both support mechanical loads (maintaining strength) and dissipate vibrational energy (reducing vibration duration), thereby resolving the technical contradiction
2Stability of the object's composition
If a rigid connection is used between the connecting strut and fastening brackets, then the structural stability is improved, but the vibration amplitude persists longer
Solution Approach 1:
The vibration damping element serves as a mediator that maintains structural stability through mechanical connection while actively reducing vibration amplitudes over time through energy dissipation, thus resolving the contradiction between stability and vibration duration
Solution Approach 2:
The patent converts the harmful effect of rigid connections (which transmit and prolong vibrations) into a beneficial effect by using viscoelastic materials that transform vibrational energy into heat, thereby reducing vibration duration while maintaining structural stability
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 vibration damping device effectively reduces the duration of lateral vibrations, allowing the table to return to a stable state quicker by absorbing and dissipating energy through elastic deformation.
Implementation Method 1
the vibration damping element is elastically deformed. Due to the elastic deformation of the vibration damping element, the vibration of the furniture can be effectively damped
Implementation Method 2
