Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air conditioner/heat pump systems face challenges in unit function expansion and pipeline connection, particularly with 'water-free floor heating' systems, where site welding introduces impurities, requires high-skilled labor, and complicates installation, leading to quality and safety issues.
Innovation Solution
An air conditioner/heat pump expansion function box with detachable nut heads and distribution pipelines allows for oxidation-free pipeline connections, eliminating impurities and the need for on-site welding, improving energy efficiency and assembly efficiency while extending unit service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If site welding is used for pipeline connection, then pipeline connection can be completed, but impurities are introduced into the pipeline system and welding quality cannot be guaranteed
Solution Approach 1:
The pipeline connection system is segmented into modular components with pre-installed connection ports. The expansion function box divides the connection interface into multiple independent ports that can be separately connected to different units, eliminating the need for on-site welding while maintaining connection reliability.
Solution Approach 2:
Connection ports are pre-installed and pre-sealed on the expansion function box and units before delivery to the construction site. This preliminary preparation ensures that no impurities are introduced during installation, as the sealed ports are only opened during controlled connection operations rather than through on-site welding.
2Ease of manufacture
If site welding is used for pipeline connection, then pipeline connection can be achieved, but installation complexity and time are increased
Solution Approach 1:
The system is divided into modular units (expansion function box, indoor units, outdoor units) with standardized connection ports. This segmentation allows for simple plug-and-play connections during installation, eliminating complex welding procedures and reducing installation time while maintaining manufacturing quality.
Solution Approach 2:
The expansion function box incorporates universal connection ports that can accommodate multiple types of units and configurations. This multi-functionality simplifies the installation process by providing a standardized interface that works across different unit types, eliminating the need for custom welding procedures for each configuration.
3Ease of operation
If site welding is used for pipeline connection, then pipeline connection can be completed, but high-skilled labor is required and promotion is difficult
Solution Approach 1:
The connection system is segmented into units with pre-installed, standardized ports that require no welding skills for connection. Installation workers simply need to perform basic connection operations at the standardized ports, dramatically reducing the skill level required while maintaining installation ease.
Solution Approach 2:
The expansion function box serves as an intermediary device with standardized connection interfaces between the units. This intermediary provides a simplified connection mechanism that mediates between different units, allowing unskilled or semi-skilled workers to perform installations without requiring welding expertise.
4Reliability
If site welding is used for pipeline connection, then pipeline connection can be achieved, but post-welding procedures are complex and hidden dangers are generated
Solution Approach 1:
All connection ports are pre-sealed and pre-prepared before delivery to the construction site. This preliminary action eliminates the need for post-welding procedures such as pressure testing, leakage detection, and cleaning, as the sealed ports ensure connection quality from the outset and require no additional verification steps.
Solution Approach 2:
The complex post-welding procedures (pressure testing, leakage detection, cleaning) are extracted and eliminated from the installation process. The pre-sealed connection ports inherently guarantee connection quality, making these additional verification and correction procedures unnecessary and thereby reducing overall installation complexity.
