Dual-Purpose Air Pump With Rotating Mechanical Switch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air pumps for inflatable products either have a single usage function when built-in or require separate storage and carrying, and lack mechanical controls for inflation and deflation adjustment.
Innovation Solution
A dual-purpose air pump with a pump body that can be integrated into or detached from a housing, featuring a twirling part for mechanical switch activation and a locking mechanism for secure attachment, allowing both built-in and standalone use with adjustable inflation and deflation controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the pump body is integrated into the housing for built-in use, then the air pump achieves compact structure and single-function inflation capability, but it loses mechanical switch control and speed adjustment functionality
Solution Approach 1:
The patent introduces a switch trigger as an intermediary component that extends from the housing to interact with the power switch on the pump body. This mediator allows the housing to control the pump body's power state even when integrated, resolving the contradiction between compact integration and operational control.
Solution Approach 2:
The power switch is designed to be rotatable relative to the housing, allowing it to dynamically change position between an engaged state (where it contacts the switch trigger for control) and a disengaged state (where it operates independently). This dynamic positioning enables the system to switch between controlled and autonomous operation modes.
2Adaptability or versatility
If the pump body is completely independent for separate use, then it can inflate various inflatable products, but it requires separate storage and carrying
Solution Approach 1:
The housing is designed with dual functionality: it serves as both the protective casing during built-in use and as a storage container when the pump body is detached. The accommodating cavity within the housing provides dedicated storage space, allowing the pump body to be neatly stored after use rather than requiring separate storage solutions.
Solution Approach 2:
The pump body can be inserted into the accommodating cavity of the housing, creating a nested configuration where the smaller pump body fits within the larger housing structure. This nesting arrangement enables compact storage and portable carrying without requiring additional storage space.
3Volume of moving object
If the inflating device is enclosed inside the outer housing, then it achieves built-in structure, but it cannot be mechanically switched on or off or adjusted for inflation and deflation speed
Solution Approach 1:
The power switch is designed with rotational movement capability, allowing it to dynamically transition between different positions. When rotated to the engaged position, it contacts the switch trigger for automated control. When rotated to the disengaged position, it operates independently, enabling speed adjustment. This dynamic positioning mechanism resolves the contradiction between enclosed structure and mechanical control.
Solution Approach 2:
The switch trigger acts as a mechanical intermediary that transmits the control signal from the housing to the power switch. It provides the necessary mechanical interface for the housing to control the pump body's power state while maintaining the built-in compact structure.

AI summary
A dual-purpose air pump comprised a pump body, a housing which is provided with an accommodating cavity receiving the pump body, a bottom of the housing has an air inlet and outlet, the pump body is rotationally mated with the housing, the pump body has a twirling part protruding from the housing; an outer side wall of the pump housing is provided with a limiting table, the housing is provided with a locking device which can move to and from an upper part of the limit table, the pump body has a power switch, and the housing has a switch trigger capable of turning off the power switch when the pump body is rotated. The pump body is built into the housing for use or removed from it for separate use, and a mechanical switch can still work when the pump body is built into the housing.
