Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigid inter-pipe fixing members are used, then they provide initial structural support, but they are prone to cracking and fail to securely fix pipelines during transportation and use
Solution Approach 1:
The inter-pipe fixing member is designed as a flexible structure that can elastically deform to accommodate pipeline movements and vibrations during refrigeration operation, preventing cracking while maintaining secure fixation. The flexibility allows the fixing member to adapt to thermal expansion and contraction without losing structural integrity.
Solution Approach 2:
The fixing member utilizes elastic deformation parameters to dynamically adjust its fixing force. When pipelines expand or contract due to temperature changes, the flexible material changes its dimensional parameters elastically, maintaining continuous contact and secure fixation without cracking.
2Ease of operation
If pipelines are not securely fixed, then assembly is simpler, but displacement and detachment occur during transportation and use
Solution Approach 1:
The fixing member incorporates movable components that can dynamically adjust to pipeline positions. The structure includes movable clamping sections that can be positioned and locked onto pipelines at different locations, providing stable fixation while maintaining ease of installation through simple insertion and locking mechanisms.
Solution Approach 2:
The fixing member is divided into multiple independent clamping sections, each capable of securing individual pipelines. This segmentation allows each section to independently adapt to pipeline positions and movements, ensuring stable fixation of multiple pipelines simultaneously while simplifying the overall assembly process.
3Strength
If rigid fixing structures are used, then they provide strong fixation, but they generate eddy current noise and eruption sounds due to turbulent two-phase flow impact
Solution Approach 1:
The flexible fixing member acts as a vibration dampener that absorbs the impact forces from turbulent two-phase flow. By elastically deforming in response to fluid dynamics, it reduces the transmission of vibrations and noise to the evaporator body, eliminating eddy current noise and eruption sounds while maintaining secure fixation.
Solution Approach 2:
The flexible material converts the harmful vibrational energy from turbulent flow into elastic deformation energy. The fixing member absorbs and dissipates the impact forces through controlled elastic deformation, transforming the harmful mechanical vibrations into harmless thermal energy through internal friction, thereby reducing noise while maintaining fixation strength.

AI summary
An inter-pipe fixing member, an evaporator and a refrigerator. The inter-pipe fixing member includes a fixing portion, which is provided with at least two fixing grooves, wherein each fixing groove is configured to be adapted to a pipeline, and the at least two fixing grooves are adapted to different pipelines, and/or the at least two fixing grooves are adapted to different sections of the same pipeline. The inter-pipe fixing member realizes fixing between different pipelines and/or different sections of the same pipeline, and when the inter-pipe fixing member is applied to the evaporator, it can be ensured that the pipelines of the evaporator are kept at a certain distance, thereby avoiding collisions.
