Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressure sensor is used to monitor air pressure inside the inflatable product, then the reliability of pressure monitoring is improved, but the cost of the inflatable product increases
Solution Approach 1:
The valve core assembly automatically monitors and regulates air pressure through its own mechanical structure without requiring external sensors or power sources. The first and second valve heads self-actuate based on pressure differential forces, opening or closing the airflow channel to maintain predetermined pressure levels, thereby eliminating the need for expensive electronic pressure sensing systems while ensuring reliable pressure control
Solution Approach 2:
The patent replaces electronic pressure sensing and control systems with a purely mechanical pressure regulation mechanism. The valve core assembly uses elastic members (springs) and pressure-bearing surfaces to create a mechanical feedback system that automatically responds to pressure changes, substituting complex electronic instrumentation with simple, reliable mechanical elements that achieve the same pressure monitoring function
2Device complexity
If empirical monitoring methods are used to monitor air pressure, then the cost is reduced, but the reliability of pressure monitoring deteriorates
Solution Approach 1:
The valve core assembly serves itself by automatically detecting pressure conditions through mechanical forces and taking corrective action without external intervention. The elastic members and valve heads form a self-regulating system that continuously monitors pressure and adjusts the airflow channel state accordingly, providing reliable automated pressure control without requiring expensive electronic sensors or manual monitoring
Solution Approach 2:
The valve core assembly implements a mechanical feedback mechanism where the pressure differential across the valve heads creates forces that automatically adjust the valve position. When pressure exceeds the predetermined level, the force closes the airflow channel; when pressure drops, the elastic members open the channel, creating a continuous feedback loop that ensures reliable pressure maintenance without electronic components
3Device complexity
If manual pressure monitoring is used, then device complexity is reduced, but productivity and automation are worsened
Solution Approach 1:
The valve core assembly automatically performs the entire pressure monitoring and regulation function without requiring manual intervention. The system self-regulates the inflation process by opening the airflow channel during inflation and automatically closing it when the predetermined pressure is reached, eliminating the need for users to manually monitor pressure or operate controls, thereby significantly improving inflation efficiency and automation
Solution Approach 2:
The valve core assembly is pre-configured with elastic members and valve heads positioned to automatically respond to pressure changes. The mechanical structure is designed in advance to detect pressure conditions and take appropriate action, allowing the system to autonomously manage the inflation process from start to finish without requiring users to understand or control the pressure regulation mechanism

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The valve maintains consistent air pressure in inflatable products, eliminating the need for manual monitoring and reducing costs by integrating automatic pressure regulation.
Implementation Method 1
a first elastic member connected to the second side of the first pressure-bearing plate... a second elastic member connected to the second side of the second pressure-bearing plate
Implementation Method 2
a first pressure-bearing plate having a first side that faces the airflow channel... upon action of an inflation pressure, the first pressure-bearing plate moves against a pressure of the first elastic member

AI summary
A constant pressure valve for an inflatable product is provided. The constant pressure valve comprises: a housing defining an airflow channel within. A first sealing seat is disposed in the airflow channel and a first through hole is formed in the first sealing seat. An inflation valve core comprises: a first actuating assembly and a first valve head. The first actuating assembly is configured to drive the first valve head to disengage from the first through hole, or to engage with the first through hole in a sealing manner. The constant pressure valve is switchable between an inflation state, in which the first valve head is disengaged from the first through hole, and the airflow channel is unblocked; and a cut-off state in which the first valve head is engaged with the first through hole in a sealing manner, and the airflow channel is blocked by the first valve head.
