Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inflating connectors for bicycle tires cannot adjust the intake gas quantity and pressure from a gas bottle, leading to tire bursts due to excessive flow, and require additional pressure gauges for measurement.
Innovation Solution
An inflating connector with a base, pressure valve, and throttling valve that allows adjustment of gas intake quantity and pressure through a throttling member and piston mechanism, preventing overlarge flow and enabling pre-set pressure without additional gauges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a gas bottle with high-pressure gas is used for inflating bicycle tires, then the inflating speed and efficiency are improved, but the risk of tire burst increases due to uncontrolled gas flow and pressure
Solution Approach 1:
The patent implements dynamic control of gas flow through a throttling valve with adjustable opening degree and a pressure valve with adjustable preset pressure. These dynamic adjustment mechanisms allow the system to adapt the gas flow rate and pressure during the inflating process, preventing tire burst while maintaining high inflating speed.
Solution Approach 2:
The patent changes the parameters of gas flow by introducing a throttling valve to adjust the opening degree (controlling flow rate) and a pressure valve to adjust the preset pressure. By modifying these parameters, the system can control the gas flow characteristics to prevent tire burst while maintaining efficient inflating.
2Loss of time
If the gas flow rate from the gas bottle is increased to reduce inflating time, then the productivity is improved, but the intake gas pressure becomes too high causing tire burst
Solution Approach 1:
The pressure valve with adjustable preset pressure provides dynamic control over the intake gas pressure. Users can set the pressure according to tire requirements, allowing fast inflating without excessive pressure that would cause tire burst.
Solution Approach 2:
The system changes the pressure parameter by introducing a pressure valve that can preset and adjust the intake gas pressure. This allows the gas flow rate to be high for fast inflating while the pressure is controlled to safe levels.
3Device complexity
If no pressure control mechanism is used in the inflating connector, then the device complexity is reduced, but the user cannot monitor or control the intake gas pressure leading to safety issues
Solution Approach 1:
The pressure valve is designed with an adjustable preset pressure function that automatically controls the gas flow pressure without requiring external pressure gauges or manual monitoring. The valve itself provides the pressure control and indication, making the system self-sufficient and reliable.
Solution Approach 2:
The pressure valve integrates multiple functions: pressure reduction, pressure presetting, and pressure indication. This multi-functional component adds reliability for safety control while minimizing the increase in device complexity by combining functions in a single component.
4Measurement precision
If a pressure gauge is added to measure the intake gas pressure, then the measurement precision is improved, but the device complexity and cost increase
Solution Approach 1:
The pressure measurement function is merged into the pressure valve itself. The pressure valve includes an adjustable preset pressure mechanism and an indication structure that directly displays the pressure information, eliminating the need for a separate pressure gauge and reducing overall device complexity.
Solution Approach 2:
The pressure valve provides its own pressure indication and measurement capability through its adjustable preset pressure mechanism and indication structure. This self-service feature eliminates the need for additional external pressure gauges, maintaining measurement precision while reducing device complexity.
