Solution Overview
Problem
Existing refrigerant supply devices for multiple-tiered heat receivers are bulky due to bent conduits and complex float-valve configurations, which increase lateral width and complexity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bent conduits and float-valve configurations are used to enable refrigerant flow between tiers, then refrigerant distribution capability is improved, but lateral width and device complexity increase
Solution Approach 1:
The patent extracts and eliminates the float-valve mechanism from the refrigerant supply device. Instead of using a complex float-valve configuration to control refrigerant flow, the invention uses simple aperture structures with blocking means that can be opened or closed. This extraction of the complex controlling mechanism directly reduces device complexity while maintaining the ability to distribute refrigerant to multiple tiers.
Solution Approach 2:
The patent segments the refrigerant supply path into multiple independent conduits (first conduit and second conduit) with separate blocking means. This segmentation allows refrigerant to be distributed to different tiers through separate paths, eliminating the need for a single complex float-valve system and reducing overall device complexity while improving distribution capability.
2Adaptability or versatility
If bent conduits are used to allow refrigerant flow down to lower tiers, then refrigerant flow capability is improved, but lateral width increases
Solution Approach 1:
The patent changes the spatial arrangement from horizontal bending to vertical stacking. Instead of using bent conduits that extend laterally to reach lower tiers, the invention uses vertically stacked aperture structures where the first and second conduits are arranged one above the other. This dimensional change from horizontal to vertical arrangement enables refrigerant flow to lower tiers without increasing lateral width.
3Manufacturing precision
If float and valve mechanisms are provided inside the liquid distribution mechanism, then refrigerant level control is improved, but lateral width and mechanism complexity increase
Solution Approach 1:
The patent replaces the expensive and complex float-valve mechanism with simple, inexpensive aperture structures and blocking means. These simpler components achieve the same refrigerant level control function without the mechanical complexity of floats and valves, directly reducing mechanism complexity while maintaining control capability.
