Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerant compressor arrangements with telescopic tubes face challenges in maintaining compact dimensions while allowing for flexible alignment and gas-tight connections, which is essential for adaptability in different refrigeration systems without increasing the overall size and risking damage during movement.
Innovation Solution
The compressor arrangement features a corrugated connection between the housing and tube sections with radial corrugations, allowing for alignment flexibility and deformability, along with a telescopic tube made of fibre-reinforced plastic and a paint-rejecting layer to simplify mounting and prevent damage, ensuring a gas-tight connection and efficient refrigerant flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a corrugated tube like area is used in the suction connection to permit adaptation to customer specific mounting conditions, then adaptability is improved, but the dimensions of the refrigerant compressor arrangement are increased
Solution Approach 1:
The tube section is nested within the housing section, with the tube section projecting into the housing section rather than extending externally. This nesting arrangement allows the suction connection to maintain adaptability through the corrugated area while keeping the overall dimensions compact by utilizing the internal space of the housing section.
2Adaptability or versatility
If the tube section is allowed to move freely in the housing to maintain connection during compressor movement, then adaptability is improved, but the risk of damage to the suction connection increases
Solution Approach 1:
The corrugated area acts as a flexible connection element between the housing section and tube section. This flexible structure allows the tube section to move and align freely within certain limits while the corrugated area absorbs the movement stresses, preventing damage to the rigid parts of the suction connection.
Solution Approach 2:
The corrugated area is designed beforehand to cushion and absorb the stresses generated during compressor movement. By anticipating and accommodating these stresses through the flexible corrugated structure, the design prevents damage before it occurs, ensuring reliable operation.
3Length of moving object
If the tube section extends into the housing section to keep dimensions small, then the length is reduced, but the alignment precision requirements increase
Solution Approach 1:
The corrugated area changes the geometric parameters of the connection, transforming it from a rigid alignment requirement to a flexible adaptation. The radial corrugations allow for angular deviations and misalignments while maintaining a gas-tight connection, thus reducing the precision requirements for coaxial alignment.

Function Achieved in This Case
This design maintains compact dimensions, allows for flexible alignment, enhances deformability, and ensures a gas-tight connection, reducing the risk of damage and improving refrigerant flow efficiency by using a fibre-reinforced telescopic tube and a paint-rejecting layer for easy mounting.
Implementation Method 1
the housing section and the tube section overlap each other and are connected to each other by a corrugated area with at least one radial corrugation
Implementation Method 2
a telescopic tube made of fibre-reinforced plastic
Implementation Method 3
the outside of the suction connection is provided with a paint rejecting layer
Implementation Method 4
a telescopic tube led through the suction opening in the housing... it is possible for the compressor to move somewhat in the housing without interrupting a connection
