Spring Vibration Isolator With Vertical Limiters for Easy Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration isolation devices for mechanical or electro-mechanical devices, such as air conditioning units, lack a simple mechanism for replacing springs without disassembling components and do not incorporate a vertical displacement limiting arrangement to prevent undesired movements and rotations.
Innovation Solution
A vibration isolation device featuring one or more spring means and vertical limiter pairs with slots and cross beams that allow for easy spring replacement and vertical displacement limitation, preventing unwanted movements and rotations by interlocking the vertical limiter pairs, which can be adjusted and tailored for specific installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If traditional mounting structures are used, then vibration isolation is provided, but spring replacement requires disassembling components such as bolts and nuts
Solution Approach 1:
The device is divided into separable components: the spring assembly can be independently removed from the mounting structure by simply lifting it out, without requiring disassembly of bolts, nuts, or other fastening components. This segmentation allows the spring to be replaced as a standalone unit.
Solution Approach 2:
The spring and its supporting components are extracted as a removable assembly from the mounting structure. The spring holder or support bar is designed to allow the spring assembly to be taken out and replaced without affecting the permanent mounting components attached to the structure being isolated.
2Stability of the object's composition
If no vertical limiting arrangement is provided, then spring replacement is simple, but undesired movements and rotations are not prevented
Solution Approach 1:
The vertical limiters are positioned asymmetrically at specific locations around the spring assembly to prevent rotation and undesired movements. The limiters are placed at strategic positions that constrain rotational motion while maintaining simplicity of the overall structure.
Solution Approach 2:
The vertical limiters provide dynamic constraint: they allow vertical movement of the spring assembly while preventing horizontal displacement and rotation. The limiters engage only when undesired movements occur, otherwise the spring assembly moves freely vertically.
3Reliability
If vertical limiters with slots and cross beams are added, then unwanted movements are prevented, but device complexity increases
Solution Approach 1:
The vertical limiters are merged with the existing mounting structure or spring holder components. Rather than adding completely separate limiter components, the limiters are integrated into the structure that already supports the spring, reducing the number of discrete parts.
Solution Approach 2:
The vertical limiter components serve multiple functions: they constrain vertical displacement, prevent horizontal movement, and inhibit rotation of the spring assembly. This multi-functionality reduces the need for separate components for each constraint function.

AI summary
A device for isolating vibration and motion which may be used to dampen or isolate vibrations and motion from heating, ventilation, air conditioning, mechanical and/or electro-mechanical equipment to reduce or eliminate the deleterious effects of vibration, movement and excessive noise created by the equipment. The device includes one or more pairs of vertical limiters, one or more springs, a pair of and at least two flanges. The frame members are each in a fixed relation to at least one vertical limiter which has a slot therein wherein the vertical limiters each have a respective engagement portion/cross beam which is partially passed through the opposing vertical limiters slot such that the vertical limiter pair allows the flanges each to move in toward or away from each other, but wherein the vertical limiters function as to prevent twisting or sliding of the flanges with respect to each other. The spring assemblies and vertical limiters receive and diminish the undesirable phenomena created by the equipment or other sources of vibrations or motion.
