Inflating Connector With Throttling Valve for Tire Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inflating connectors for bicycle tires cannot adjust intake gas quantity and pressure from a gas bottle, leading to potential tire bursts and requiring additional tools for pressure measurement, making the inflating process inconvenient.
Innovation Solution
An inflating connector with a base, pressure valve, and throttling valve that allows adjustment of gas quantity and pressure, featuring a piston and elastic member to regulate intake pressure and a throttling member to control gas flow, eliminating the need for external pressure gauges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gas flows directly from gas bottle to bicycle tire without adjustment, then inflating speed is fast, but tire may burst due to over large intake gas quantity or over high intake gas pressure
Solution Approach 1:
The patent introduces a base with controlled passageways as an intermediary device between the gas bottle and bicycle tire. The base includes a first passageway with adjustable cross-sectional area and a second passageway, creating a controlled intermediate channel that regulates gas flow rate and pressure, preventing direct uncontrolled flow while maintaining efficient inflating speed.
Solution Approach 2:
The patent employs adjustable passageway cross-sectional areas to dynamically change flow parameters. The first passageway's cross-sectional area can be adjusted to control gas flow rate, and the second passageway's area is optimized for pressure regulation, enabling the system to adapt parameters to prevent tire burst while maintaining high inflating speed.
2Measurement precision
If user wants to measure intake gas pressure, then accurate pressure measurement is achieved, but additional pressure gauge or air pump with pressure gauge is required which is inconvenient
Solution Approach 1:
The patent combines the pressure measurement function directly into the base structure. The base integrates a passageway system with controlled cross-sectional areas that inherently regulate and indicate pressure, eliminating the need for separate pressure gauges or specialized air pumps. The structure itself serves as both the flow control mechanism and the pressure measurement reference.
Solution Approach 2:
The base's passageway design enables self-measurement of pressure through its geometric properties. The controlled cross-sectional areas create predictable pressure drops and flow characteristics that inherently provide pressure information, allowing the system to measure and regulate pressure without external measurement devices.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents tire bursts by adjusting gas quantity and pressure, allowing for convenient pre-setting of intake pressure without additional measurement tools, enhancing user convenience and safety.
Implementation Method 1
The elastic member acts on the piston to make the plug portion close up the entrance section
Implementation Method 2
The operation unit is arranged for driving the throttling member to displace back and forth along an axis of the gas outlet passageway to change the size of a communication space between the gas outlet passageway and the first connecting passageway

AI summary
An inflating connector (1, 2, 3) of the present invention includes a base (10), a pressure valve (20), a gas bottle connecting seat (30), and a throttling valve (41). The base (10) has an assembling passageway (13), a first gas passageway (14) communicating with the assembling passageway (13), and a second gas passageway (15) communicating with the assembling passageway (13), for a gas nozzle to be connected with the second gas passageway (15). The pressure valve (20) has an elastic member (28) and a piston (24), which are accommodated in the first gas passageway (14). The elastic member (28) acts on the piston (24) to make it close up the first gas passageway (14). The gas bottle connecting seat (30) is disposed on a side of the assembling passageway (13), and has a gas inlet passageway (32) for being connected with a gas bottle (4) and a gas outlet passageway (37) communicating with the gas inlet passageway (32). The throttling valve (41) is disposed on another side of the assembling passageway (13), and has an operation unit (46) and a throttling member (42) capable of being driven by the operation unit (46) to displace along the gas outlet passageway (37). As a result, the inflating connector (1, 2, 3) of the present invention can change the intake gas quantity and intake gas pressure of the gas flowing thereinto from the gas bottle (4).
