Tire Inflation Interface for Multi-Source Power and Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current breakdown assistance devices for sealing and inflating vehicle tires require a power connection to the vehicle's on-board power socket, which is becoming less common, especially in electric cars, and the compressor's power requirements are not compatible with all power sources, limiting their flexibility and usability.
Innovation Solution
A breakdown assistance device with an interface that supplies power and transmits data, allowing the use of alternative power sources and enabling flexible operation, including decentralized power sources like power banks, and featuring a USB interface for power and data transmission, supporting voltages greater than 12 volts to accommodate various vehicle systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the breakdown assistance device is connected to the vehicle on-board power socket, then the compressor can be powered reliably, but the device cannot be used in vehicles without such sockets (like electric cars) or when the power source is decentralized
Solution Approach 1:
The interface is designed to support multiple power sources and connection types (vehicle on-board power socket, decentralized power sources, mobile power sources like power banks), allowing the breakdown assistance device to function universally across different vehicle types and power configurations
Solution Approach 2:
The interface acts as an intermediary between the compressor and various power sources, adapting the connection and power delivery to match the specific power source being used, whether it's a traditional vehicle socket or a mobile power bank
2Power
If the compressor requires high power to meet compressed air requirements, then the inflation performance is sufficient, but not every power source is suitable
Solution Approach 1:
The interface enables dynamic adaptation of power delivery based on the connected power source, adjusting the compressor operation to match the available power while maintaining sufficient inflation performance when high-power sources are available
Solution Approach 2:
The system can change operational parameters (power consumption levels) based on the connected power source capabilities, allowing the compressor to operate at high power when connected to vehicle sockets and at reduced power when connected to mobile power sources
3Reliability
If the vehicle on-board power socket is used, then power supply is reliable, but the connection cable length is limited by the distance from the power socket to the tire valve
Solution Approach 1:
The interface serves as an intermediary that can connect to decentralized power sources located near the tire valve, eliminating the need for long cables stretching from the vehicle's central power socket to the tire
