Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for reducing piping vibrations in air conditioning systems, particularly those using weight materials, are ineffective in wide frequency ranges, especially for inverter compressors, leading to inadequate vibration reduction and potential pipe damage.
Innovation Solution
A damper system comprising a fixation part directly contacting the pipe, a weight part spaced apart from the pipe, and a slitting part, allowing for adjustable weight distribution based on compressor type and pipe shape, to effectively reduce piping vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a weight material is added to the pipe to decrease piping vibration, then the natural frequency of the pipe is moved to a lower frequency band, but the vibration reduction effect is not large especially in wide frequency ranges
Solution Approach 1:
The damper is divided into three distinct segments: a fixation part that contacts the pipe, a weight part that provides mass, and a slitting part that connects them. This segmentation allows each part to perform its specific function optimally - the fixation part ensures stable attachment, the weight part provides vibration reduction through mass, and the slitting part allows controlled movement between them, improving overall vibration reduction efficiency across wide frequency ranges
Solution Approach 2:
The slitting part creates a dynamic connection between the fixation part and weight part, allowing relative movement rather than rigid fixation. This dynamic structure enables the damper to adapt to varying vibration frequencies, particularly effective for inverter compressors that operate across wide frequency ranges, thereby improving vibration reduction effectiveness
2Device complexity
If a weight material is integrally fixed to the pipe using a fixation clip or cable tie, then the structure is simple, but the vibration reduction effect is insufficient
Solution Approach 1:
The damper is divided into three distinct segments: a fixation part that contacts the pipe, a weight part that provides mass, and a slitting part that connects them. This segmentation allows each part to perform its specific function optimally - the fixation part ensures stable attachment, the weight part provides vibration reduction through mass, and the slitting part allows controlled movement between them, improving overall vibration reduction efficiency
Solution Approach 2:
Different parts of the damper have different properties optimized for their specific functions: the fixation part has elastic properties for stable contact with the pipe, the weight part has high mass for vibration reduction, and the slitting part has controlled flexibility. This local differentiation of properties enhances the overall vibration reduction effect while maintaining structural simplicity
3Adaptability or versatility
If a weight material is applied to a pipe with constant speed compressor, then only a predetermined frequency range needs to be avoided, but this approach fails for inverter compressors with wide frequency range
Solution Approach 1:
The slitting part creates a dynamic connection between the fixation part and weight part, allowing relative movement rather than rigid fixation. This dynamic structure enables the damper to adapt to varying vibration frequencies, particularly effective for inverter compressors that operate across wide frequency ranges, thereby improving vibration reduction effectiveness
Solution Approach 2:
The damper design with separable fixation part, weight part, and slitting part creates a universal solution that can effectively handle vibration across wide frequency ranges, making it suitable for both constant speed compressors and inverter compressors, thereby achieving multi-frequency adaptability

AI summary
A damper for decreasing a piping vibration capable of enhancing the efficiency in decreasing the piping vibration and adjusting the weight of a weight portion according to the type of the compressor and the shape of the pipe applied to the compressor by separating a fixed portion from a weight portion such that the fixed portion makes a direct contact with a pipe and the weight portion has an interval from the pipe without making a direct contact with the pipe, in which the damper installed on the pipe to decrease the vibration includes a fixation part provided with a coupling hole formed therein to be coupled to the pipe, and coupled and fixed to the pipe such that the coupling hole makes contact with an outer circumferential surface of the pipe, and a weight part connected to the fixation part.
