Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air pump assemblies lack the ability to individually or partially inflate or deflate multiple objects, limiting their range of application.
Innovation Solution
An air inflation device with a body, switching valves, and a deflation valve that allows for air distribution, enabling multiple objects to be all or partially inflated or deflated simultaneously through a pumping part, outlets, and a deflation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional simple air pump is used, then the device structure is simple, but the device lacks air distribution ability and cannot partially or individually inflate multiple objects
Solution Approach 1:
The air pump assembly is segmented into multiple independent outlets (first outlet and second outlet), each equipped with its own switching valve. This segmentation allows air to be directed to different objects independently, enabling partial or individual inflation of multiple objects while maintaining a relatively simple overall structure.
Solution Approach 2:
Switching valves are introduced as intermediary components between the air pump and the outlets. These valves act as mediators that control the direction of air flow, allowing the user to select which outlet receives air. This adds air distribution capability without requiring a completely complex system redesign.
2Ease of operation
If multiple objects are inflated simultaneously using a conventional air pump, then all objects are inflated, but individual or partial inflation control is lost
Solution Approach 1:
The control system is segmented by providing a separate switching valve for each outlet. Each valve can be independently operated to control air flow to its corresponding outlet, enabling individual inflation control. This segmentation of control functions simplifies the user interface while achieving the desired functionality.
Solution Approach 2:
The switching valves provide dynamic control over air distribution. The user can adjust the system in real-time by opening or closing specific valves during the inflation process, allowing flexible control over which objects are inflated and to what extent, rather than a static all-or-nothing system.
3Adaptability or versatility
If a deflation valve is added to enable deflation, then deflation capability is achieved, but the device complexity increases
Solution Approach 1:
The deflation valve is integrated into the existing valve assembly structure, sharing the same mounting space and structural support as the switching valves. This merging of components allows deflation functionality to be added without proportionally increasing the overall device complexity, as the deflation valve utilizes existing structural elements.
Solution Approach 2:
The valve assembly is designed with multi-functionality, where the same structural framework supports both the switching valves (for inflation control) and the deflation valve (for deflation). This universal design approach allows multiple functions to be achieved within a compact, integrated structure rather than requiring separate independent systems.

AI summary
An air inflation device has a body, two switching valves, and a deflation valve. The body has an interior space formed therein, two outlets formed thereon at a spaced interval, and a pumping part. The pumping part is elastic and is pressable to compress air in the interior space to flow toward the two outlets. Each one of the two switching valves is disposed to the body and is operable to communicate with the interior space and a respective one of the two outlets. The deflation valve is disposed to the body and is operable to allow the interior space and an exterior space of the body to communicate with each other. The two switching valves allow multiple objects to be all or partially inflated or deflated at a time by operating the pumping part or the deflation valve.
