Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tables with traditional frames experience prolonged lateral vibrations due to lateral forces, particularly in designs with long legs, leading to slow vibration decay.
Innovation Solution
Incorporation of a vibration-damping means, such as an elastically yielding element or collar, between the connecting strut and fastening brackets to absorb and dissipate lateral vibrations, reducing vibration amplitudes and shortening the vibration period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional rigid connection is used between the connecting strut and fastening brackets, then the structural strength and stability are improved, but lateral vibrations last for a relatively long time
Solution Approach 1:
The patent introduces a vibration-damping means as an intermediary element between the connecting strut and fastening brackets. This intermediary component absorbs and dissipates lateral vibrations through elastic deformation, reducing vibration duration while maintaining structural integrity. The damping means acts as a mediator that allows controlled relative movement to reduce vibrations without compromising the overall structural strength.
Solution Approach 2:
The patent changes the connection parameter from rigid to elastically yielding by introducing vibration-damping elements. This parameter change allows the connection to exhibit both strength (through elastic properties) and vibration damping (through controlled deformation). The elastic collar or damping element changes the mechanical parameter of the joint from purely rigid to a combination of rigid and flexible, enabling simultaneous achievement of strength and vibration reduction.
2Object-affected harmful factors
If elastically yielding vibration-damping elements are used to connect the connecting strut to fastening brackets, then lateral vibrations are damped effectively, but the device complexity increases
Solution Approach 1:
The patent employs an elastic collar as a flexible element that surrounds the connecting strut. This flexible shell structure provides vibration damping through its elastic properties while maintaining a relatively simple geometric form. The collar's flexible nature allows it to deform elastically under lateral vibrations, absorbing energy without requiring complex internal mechanisms or multiple components.
Solution Approach 2:
The vibration-damping means may be constructed using composite material principles, combining materials with different properties to achieve both structural support and vibration damping. The elastic collar or damping element can be made from composite materials that provide both the necessary mechanical strength for structural support and the elastic properties for effective vibration damping, thereby controlling harmful vibrations without significantly increasing device complexity.
3Ease of manufacture
If the vibration-damping element is designed as a collar extending over the end region of the connecting strut, then the manufacturing and assembly are simplified, but the extent of vibration damping may be reduced
Solution Approach 1:
The patent applies the vibration-damping collar selectively to the end region of the connecting strut where it overlaps with the fastening bracket. This local application of the damping element concentrates the vibration damping function at the critical connection point, where lateral vibrations are most problematic. By placing the damping collar specifically at the connection interface rather than along the entire length of the strut, the design achieves effective vibration control with minimal material and simplified assembly.

Function Achieved in This Case
The vibration-damping elements effectively reduce the duration of lateral vibrations, allowing them to fade away more quickly, enhancing the stability and comfort of the table.
Implementation Method 1
the vibration-damping element is elastically deformed. Owing to the elastic deformation of the vibration-damping element, the vibration of the piece of furniture can be damped effectively
