Solution Overview
Problem
Conventional air compressor devices and sealing/inflating assemblies face difficulties in quickly and easily coupling and decoupling with inflatable objects, requiring complex coupling structures and additional components, which hinders efficient sealing and inflation processes.
Innovation Solution
A quick coupling device with a C-shaped coupler and anchor plate system allows for easy attachment and detachment of parts to the air compressor's outlet tube, featuring a check valve for unidirectional air flow and a rotating mechanism for secure locking, enabling quick and changeable connections without additional coupling devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional coupling structures are used to connect the pressure tight container to the air compressor, then the connection is secure and reliable, but the coupling process becomes complicated and time-consuming
Solution Approach 1:
The coupling system is divided into separate male and female coupling portions with distinct functions. The male coupling portion on the pressure tight container connects to the female coupling portion on the air compressor outlet tube, allowing independent optimization of each component and simplifying the overall coupling mechanism while maintaining secure connection.
Solution Approach 2:
The coupling mechanism uses a rotational locking approach where the coupler rotates to lock into place rather than using complex threaded or clamped connections. This inverted approach to traditional coupling methods achieves secure connection through rotational engagement of the C-shaped coupler with the outlet tube.
2Adaptability or versatility
If additional coupling devices and valves are added to enable sealing and inflation functions, then the functionality is improved, but the device complexity and number of components increase
Solution Approach 1:
The coupling device integrates multiple functions into a single component structure. The C-shaped coupler simultaneously provides mechanical connection, sealing surface, and rotational locking mechanism, eliminating the need for separate coupling devices, seals, and valves that would otherwise be required.
Solution Approach 2:
The quick coupling device is designed to be universally applicable for both sealing and inflation operations. The same coupling mechanism handles both the pressure tight container connection and the inflatable object connection, providing multi-functional capability without requiring additional specialized components.
3Reliability
If a secure locking mechanism is implemented to ensure reliable connection, then the connection stability is improved, but the ease of quick detachment is reduced
Solution Approach 1:
The coupling mechanism transitions from a static locked state to a dynamic quick-release state through simple rotational motion. The C-shaped coupler can be easily rotated to unlock and detach, providing dynamic operation that maintains secure connection during use but allows rapid detachment when needed.
Solution Approach 2:
The coupling and decoupling operations require approximately equal effort and complexity. The rotational locking mechanism that provides secure connection can be reversed with the same simplicity, achieving equipotential ease of operation for both attachment and detachment phases.
4Adaptability or versatility
If multiple valves and coupling points are added to the air compressor outlet, then the functionality for different operations is improved, but the ease of direct coupling to inflatable objects is reduced
Solution Approach 1:
The essential coupling functionality is extracted from the complex multi-valve system and embodied in the simple quick coupling device. This extracted coupling mechanism provides direct connection capability while the sealing and inflation functions are achieved through the integrated operation of the pressure tight container and inflatable object couplings.
