Compact Inflatable Pump with Nested Battery Housing to Reduce Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional inflatable products face issues with large built-in pumps, air leakage, and the need for external power supply, making them inconvenient for outdoor use and prone to damage.
Innovation Solution
An inflatable pump design with a modular structure that includes a spacer plate dividing the housing into upper and lower cavities, a drive motor in the lower cavity, a fan blade in the upper cavity, and a handle for easy operation, along with a compact design and integrated battery for power, reducing the overall size and likelihood of air leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a built-in pump is integrated into the inflatable product, then the inflatable product can be inflated automatically, but the pump occupies large space and increases the overall size of the product
Solution Approach 1:
The pump housing is designed as a hollow structure that contains and integrates the battery pack, control box, and other components within its cavity. This nesting arrangement allows multiple functional components to occupy the same spatial envelope, significantly reducing the overall volume of the pump assembly while maintaining all necessary functions for automatic inflation.
Solution Approach 2:
The pump housing serves multiple functions simultaneously: it provides structural support, contains the motor and fan assembly, houses the battery pack in its hollow cavity, and acts as the air delivery chamber. This multi-functionality eliminates the need for separate housings for each component, thereby reducing the total volume occupied by the pump system.
2Volume of moving object
If the pump housing is made hollow to accommodate battery pack, then the space occupation is reduced, but the structural strength may be compromised
Solution Approach 1:
The pump housing is constructed from high-strength engineering plastics or composite materials that provide both the necessary structural integrity and the capability to form hollow cavities. These materials offer high strength-to-weight ratios, allowing the housing to maintain structural strength while being formed into hollow shapes that accommodate the battery pack and other components.
Solution Approach 2:
The hollow pump housing is divided into multiple structural segments or ribs that provide reinforcement. These internal structural elements maintain the structural strength of the housing while allowing the hollow cavity to accommodate the battery pack, effectively solving the contradiction between reduced volume and maintained strength.
3Volume of moving object
If the mounting cavity is divided into upper and lower cavities, then the components are organized and space is optimized, but the device complexity increases
Solution Approach 1:
The mounting cavity is segmented into an upper mounting cavity for the motor and fan assembly and a lower mounting cavity for the battery pack and control box. This segmentation is achieved through a simple horizontal partition within the hollow housing, which organizes components vertically without requiring complex multi-level structures, thereby optimizing space while maintaining relatively simple device architecture.
4Ease of operation
If traditional inflatable beds use integrated built-in pumps, then inflation is convenient, but air leakage occurs and comfort is poor for long-term use
Solution Approach 1:
The pump assembly is extracted from being fully integrated within the inflatable bed structure and positioned as a separate movable unit with its own hollow housing. This extraction allows the pump to be removed and replaced independently of the inflatable bed, enabling the use of high-quality sealed inflatable chambers that are less prone to air leakage, while the pump serves as a separate inflation device.
