Solution Overview

Problem

Conventional heat pumps are not sufficiently quiet due to vibrations from the compressor and other components, which are not effectively isolated, leading to noise exposure.

Innovation Solution

Positioning multiple heat pump components on a common carrying element perpendicularly above a load transfer element, with a resilient insulating element between the carrying element and the load transfer element, and using a compressor connected to the same load transfer element, along with strategically designed fluid lines to reduce vibration transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If heat pump components are arranged separately without a common carrying element, then installation flexibility is improved, but vibration isolation and noise reduction are worsened

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidnoise exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Multiple heat pump components (compressor, heat exchangers, expansion device, valve) are merged onto a single common carrying element, which is collectively isolated from the load transfer element. This merging allows the entire component assembly to be isolated as one unit, preventing vibrations from individual components from transmitting to the housing, while still allowing flexible installation orientations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

A resilient insulating element is introduced as an intermediary between the common carrying element and the load transfer element. This intermediary absorbs and dampens vibrations from all heat pump components before they can transmit to the housing, effectively reducing noise exposure while maintaining structural support.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If components are positioned away from the load transfer element, then vibration transmission is reduced, but structural stability is worsened

Engineering Contradiction:
Improvevibration transmissionVSAvoidstructural stability
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The resilient insulating element serves as a mediator that simultaneously provides vibration isolation and structural support. It positions the common carrying element at an optimal distance from the load transfer element to reduce vibration transmission while maintaining sufficient structural stability to support all heat pump components during operation.

Inventive Principle:
Principle #24Intermediary (Mediator)
