Temporary Mobility Kit Sealant Flow Control Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current temporary mobility kits (TMKs) face issues with premature sealant dispersion due to incomplete hose connections and mis-spraying of sealant when the diverter switch is not properly positioned, leading to potential sealant wastage and inefficiency.
Innovation Solution
Incorporation of a control circuit with metal contacts and leads in the sealant hose and kit housing that closes a switch only when the sealant hose is properly attached to the tire valve, ensuring sealant is released only when the power is connected and the diverter valve is in the correct position, preventing inadvertent flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealant hose is not completely connected to the tire valve, then the device can be assembled quickly, but sealant is prematurely dispersed and wasted
Solution Approach 1:
The control circuit performs preliminary verification of the connection condition through metal contacts before allowing sealant flow. The system checks whether the sealant hose is properly connected to the tire valve before enabling the sealant pump, preventing premature dispersion while maintaining ease of assembly.
Solution Approach 2:
The control circuit provides feedback by detecting the connection status through metal contacts and automatically preventing sealant flow until proper connection is confirmed. This feedback mechanism ensures sealant is only released when the hose is completely connected, eliminating wastage while keeping the operation simple.
2Adaptability or versatility
If the diverter switch is over turned, then the device can be operated flexibly, but sealant is mis-sprayed
Solution Approach 1:
The control circuit performs preliminary verification of the diverter switch position before enabling sealant flow. It checks whether the switch is in the correct position and only allows sealant to be sprayed when the position is verified, preventing mis-spraying while maintaining operational flexibility.
Solution Approach 2:
The control circuit continuously monitors the diverter switch position through metal contacts and provides feedback control. If the switch is incorrectly positioned, the circuit automatically prevents sealant flow, ensuring reliable spraying accuracy while allowing flexible operation when conditions are correct.
3Productivity
If the on-switch is pressed without connecting the sealant hose, then the device can be activated quickly, but sealant is sprayed out inadvertently
Solution Approach 1:
The control circuit performs preliminary verification of the connection condition through metal contacts before allowing the on-switch to activate sealant flow. Even if the user presses the on-switch quickly, the system checks whether the hose is connected first, preventing inadvertent spray and sealant loss while maintaining fast activation when properly connected.
Solution Approach 2:
The control circuit provides real-time feedback on connection status through metal contacts, blocking the on-switch signal from activating sealant flow until proper connection is detected. This feedback mechanism prevents sealant loss while allowing rapid activation when the connection is correct.
