Problem

Existing heat pump devices face challenges in effectively controlling vibrations and noise generated by compressors, leading to discomfort and inefficiency, particularly due to complex and difficult-to-handle vibration control systems.

Innovation Solution

A device featuring two non-metallic, offset bellows arrangements with ring-shaped folds that simulate spherical segments, integrated into a one-piece pipe section, providing effective vibration and noise reduction with a simple design for easy assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If complex vibration control devices with multiple components are used, then vibration and noise control effectiveness is improved, but device complexity and difficulty of assembly increase

Engineering Contradiction:
Improvevibration and noise transmissionVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines multiple vibration control functions into a single integrated bellows component. The bellows structure integrates vibration absorption, noise reduction, and flexible connection capabilities that were previously requiring separate components, thereby reducing assembly complexity while maintaining effective vibration and noise control

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs a bellows structure made of flexible material that acts as both a vibration absorber and a flexible connection element. The bellows' accordion-like structure provides inherent vibration damping while maintaining fluid tightness, eliminating the need for separate vibration isolation components and simplifying the overall device structure

Inventive Principle:
Principle #30Flexible shells and thin films

2Stability of the object's composition

If traditional rigid pipe connections are used, then structural stability is maintained, but vibration transmission from compressor to condenser occurs

Engineering Contradiction:
Improvestructural stabilityVSAvoidvibration transmission
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The bellows structure serves as a flexible connection between the compressor and condenser, replacing rigid pipe sections. The flexible material and accordion design allow the connection to absorb vibrations while maintaining structural integrity and fluid tightness, thus preventing vibration transmission while preserving stability

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The bellows is pre-designed with vibration-absorbing characteristics through its folded structure and material selection. This inherent cushioning capability is built into the connection itself before installation, allowing it to passively absorb vibrations from the compressor without requiring additional active vibration control mechanisms

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The invention relates to a device (2) in the form of a connecting pipe for use in heat pump means for decoupling and for vibration control, comprising a pipe section (R) and in each case one connector element arranged on the end side. The device (2) comprises precisely two non-metallic gaiter arrangements (F), which are spaced apart and arranged offset, for vibration compensation, wherein the pipe section (R) has a constant material thickness between the connector elements, apart from possible individual stabilizing rings (15). In addition, the gaiter arrangements (F) consist of one or more annularly closed folds which in each case run around by 360°.
