Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scooters require manual inflation of wheels, which is burdensome for users and can lead to insufficient or inappropriate tire pressure, increasing wear and safety risks.
Innovation Solution
A scooter with an automatic inflation system that includes a pressure gauge, gas tank, and control unit to maintain optimal wheel pressure without user intervention, using a pressure measurement assembly, valve assembly, and pressure control assembly to adjust air flow based on detected pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual inflation is used, then users can control wheel pressure, but users must regularly check and re-inflate wheels which is burdensome and time-consuming
Solution Approach 1:
The system enables the wheel inflation process to serve itself automatically. The pressure gauge continuously monitors wheel pressure and automatically activates the heating element to inflate the wheel when pressure drops, eliminating the need for user intervention in checking and inflating wheels.
Solution Approach 2:
The pressure gauge provides continuous feedback on wheel pressure to the control system. When the pressure drops below a threshold, the system receives feedback and automatically activates the heating element to restore pressure, creating a closed-loop control system that responds to actual wheel conditions.
2Reliability
If manual inflation is used, then users can adjust pressure, but users may forget to check tire pressure increasing safety risks
Solution Approach 1:
The system monitors and maintains wheel pressure automatically without requiring user attention. The pressure gauge continuously checks pressure levels and the heating element automatically inflates the wheel when needed, making the system self-responsible for pressure maintenance.
Solution Approach 2:
The pressure gauge operates continuously to monitor wheel pressure, ensuring uninterrupted surveillance of pressure levels. This continuous monitoring eliminates gaps where pressure could drop to unsafe levels, maintaining constant protection.
3Reliability
If automatic inflation system is added, then wheel pressure is automatically maintained, but device complexity increases
Solution Approach 1:
The heating element serves dual purposes: it heats the air inside the wheel for inflation, and its positioning also provides structural support. The pressure gauge integrates multiple functions including pressure sensing, signal processing, and control activation within a single component.
Solution Approach 2:
The pressure gauge and heating element are integrated into a unified system mounted on the wheel hub. The control unit combines pressure monitoring, decision-making, and activation control in a single electronic controller, reducing overall system complexity through functional integration.
4Reliability
If continuous pressure monitoring is implemented, then optimal pressure is maintained, but energy consumption increases
Solution Approach 1:
The pressure gauge performs periodic pressure checks rather than continuous monitoring. The system activates the heating element in periodic cycles based on pressure threshold detection, reducing energy consumption while maintaining effective pressure management through intermittent measurement and action.

AI summary
A scooter is provided, including a wheel(s), a gas tank, and a pressure gauge. Each wheel includes a hub and a tire. The gas tank is disposed on the hub. The pressure gauge includes a pressure measurement assembly, a valve assembly, and a pressure control assembly. The pressure measurement assembly is connected with a lumen of the tire to detect a target pressure of air in the lumen. The valve assembly is connected with the lumen and the gas tank and includes a second gas channel. The pressure control assembly is electrically connected with the pressure measurement assembly and the valve assembly, is in communication connection with a control unit of the scooter, and is configured to periodically transmit the target pressure to the control unit and control the valve assembly to open or close the second gas channel based on a target instruction sent by the control unit.
