Portable Pump Motor Housing for Quick Replacement and Dark Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable pumps face issues with clogging, motor failure, battery drainage, and limited operational capabilities in pumping large volumes, dirty liquids, and long-distance or high-height applications, especially in dark or confined environments, where they often require manual attention and struggle to maintain upright positioning.
Innovation Solution
A portable pump design featuring a removable motor housing, LED lighting for dark conditions, adjustable height, and a self-supporting stand that allows operation at a slight angle, enabling easy motor access and maintenance, along with a flexible hose system for adaptability in various pumping scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pump is designed as a conventional portable unit, then it can be easily moved and used in various locations, but it fails to operate reliably in difficult circumstances such as pumping large volumes or dirty liquids
Solution Approach 1:
The pump is divided into separate functional modules: a motor housing containing the electric motor, a main body housing containing the pump mechanism, and a removable end cap. This segmentation allows each component to be optimized independently and facilitates easy replacement of the motor if it fails, thereby improving reliability while maintaining adaptability across different pumping conditions
2Ease of repair
If the pump uses a fixed motor housing, then the structure is compact and simple, but the motor cannot be easily replaced when it fails
Solution Approach 1:
The motor housing is designed as a separate, removable module that can be detached from the main body without disassembling the entire pump. The motor itself can be quickly replaced by removing the end cap and motor housing assembly, significantly improving ease of repair while adding only minimal structural complexity through standardized connection interfaces
Solution Approach 2:
The motor is extracted as a removable component from the integrated pump structure. The motor housing can be completely removed from the main body, allowing the motor to be replaced independently without affecting other pump components, thus improving repairability with minimal impact on overall device complexity
3Extent of automation
If the pump requires manual attendance during operation, then it can be monitored and adjusted, but it cannot operate unattended in dark or confined locations
Solution Approach 1:
The pump incorporates an integrated LED lighting system that automatically illuminates the work area when the pump is operating in dark or confined locations. This self-service lighting feature enables unattended operation by providing necessary illumination without requiring human presence, thereby increasing automation extent while addressing the illumination requirement

AI summary
A pump for non-flammable liquids has an improved mounting for the motor which facilitates the relatively quick and easy removal of the motor from the pump. The pump has a main body which is hollow and cylindrical. A motor housing is connected to the main body by threads at a first end and has a removable end cap on its second end. The electric motor is located in said motor housing and secured when the end cap is on the motor housing. An electronics housing has a battery adapter plate, a switch, and a discharge port, and encloses wires and electronics such that the motor pumps the liquid from the end cap, through the motor housing and the main body, and out of the discharge port when the switch is turned on.
