Fluid pump assembly for window air conditioner and window conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The orientation of the pipe connection structure in the fluid pump of a window air conditioner necessitates a directional mounting, complicating the assembly process and reducing efficiency.
Innovation Solution
A fluid pump assembly with a first positioning structure on the pump and a second positioning structure on a fixation shell, allowing for engagement to fix the mounting position and orientation, simplifying assembly by ensuring the pipe connection structure aligns with the fixation shell's open end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fluid pump uses a pipe connection structure with fixed orientation, then the connection with the pipeline is reliable, but the mounting direction must be identified which reduces assembly efficiency
Solution Approach 1:
The end portion of the fluid pump is designed with an asymmetric non-circular cross-section featuring at least one corner, creating a first positioning structure. This asymmetric geometry ensures that the pump can only be mounted in the correct orientation, as the corner aligns with a corresponding positioning groove in the fixation shell, eliminating the need for directional identification during assembly while maintaining reliable pipe connection.
Solution Approach 2:
The positioning structure enables the fluid pump to self-align and self-position during assembly. The asymmetric end portion with the corner automatically orients itself to fit into the positioning groove of the fixation shell, allowing the pump to find its correct mounting position without external guidance or directional marking, thus improving assembly efficiency while ensuring connection reliability.
2Manufacturing precision
If the fluid pump is directionally mounted to ensure proper pipe connection alignment, then the connection accuracy is improved, but the assembly process becomes more complex
Solution Approach 1:
The non-circular cross-section with a corner creates an inherent asymmetric positioning feature that guarantees precise mounting orientation. This geometric constraint ensures the pipe connection structure aligns accurately with the connection pipeline while simplifying the assembly process, as the asymmetric shape provides built-in alignment guidance without requiring complex fixtures or procedures.
Solution Approach 2:
The first positioning structure (asymmetric end portion with corner) is pre-formed on the fluid pump during manufacturing, and the second positioning structure (positioning groove) is pre-formed on the fixation shell. These preliminary positioning features are integrated into the component designs, ensuring that when assembled, the mounting precision is automatically achieved without requiring additional alignment steps or complex assembly procedures.

AI summary
A fluid pump assembly includes a fluid pump and a fixation shell accommodating the fluid pump. The fluid pump includes a pipe connection structure at an end portion of the fluid pump and a first positioning structure. The fixation shell has a closed end and an open end opposite to the closed end, and includes a second positioning structure engaged with the first positioning structure to position the pipe connection structure to correspond to the open end of the fixation shell.
