Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressor devices and sealing/inflating assemblies face difficulties in quickly and easily coupling and decoupling with inflatable objects, as well as efficiently supplying pressurized air through complex coupling structures, which hinders direct and rapid inflation of objects like tires and air cushions.
Innovation Solution
A sealing and inflating assembly featuring a quick coupling device with a C-shaped coupler and anchor plate system that allows easy attachment and detachment of components to an air compressor's outlet tube, along with a check valve to control air flow, enabling quick and changeable connections without additional coupling devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional coupling structures with shut off valves, gas outlets, and additional riser tubes are used to connect the pressure tight container to the air compressor, then the sealing preparation can be supplied to inflate objects, but the coupling structure becomes complicated and the components cannot be easily or quickly attached or detached
Solution Approach 1:
The coupling system is divided into separate male and female coupling components with distinct functional elements (threaded connection, bayonet latch, quick release button), allowing independent optimization of each component and easy assembly/disassembly without complex integrated structures
Solution Approach 2:
The coupling mechanism transitions from static rigid connections to dynamic controlled connections through the bayonet latch and quick release button, enabling rapid engagement and disengagement while maintaining secure connection during operation
2Productivity
If additional coupling devices and valves are added to supply pressurized air through the pressure tight container, then inflation can be achieved, but the air supply path becomes indirect and the inflation process is slower
Solution Approach 1:
The air supply function is extracted from the complex valve system and integrated directly into the coupling mechanism itself, eliminating intermediate components and creating a direct air path from the compressor through the coupling to the inflatable object
Solution Approach 2:
The coupling mechanism merges multiple functions (mechanical connection, sealing, and air supply control) into a single integrated system, eliminating the need for separate coupling devices and valves while maintaining all necessary functions
3Reliability
If the pressure tight container is firmly secured to the air compressor for reliable connection, then air supply stability is improved, but the container cannot be quickly removed for versatile use
Solution Approach 1:
The connection system provides dynamic characteristics with two distinct states: a locked engaged state for reliable operation and a released state for quick removal, controlled by the bayonet latch mechanism and quick release button
Solution Approach 2:
The coupling components are designed as universal interfaces that can connect the pressure tight container to various inflatable objects (tires, air beds, cushions), allowing the system to serve multiple purposes while maintaining secure connection during each operation
