Mixing Device for Puncture Repair Kits with Agglomerate Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional puncture repair kits require a large amount of puncture repair liquid and a long time to seal punctured areas due to the sequential injection of compressed air after the liquid, which is inefficient.
Innovation Solution
A mixing device with a mixing chamber, a first inlet for compressed air, a second inlet for puncture repair liquid, and an outlet for the mixture, featuring a deposition section between the inlets and outlet to deposit agglomerates, allowing for efficient mixing and quick repair by pulsating air to mix the liquid and air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed air is injected after puncture repair liquid in sequential injection, then the puncture can be sealed, but a large amount of puncture repair liquid is needed and the repair time is long
Solution Approach 1:
The patent combines the injection of puncture repair liquid and compressed air into a single simultaneous injection process through a mixing chamber. The liquid and air are mixed before being injected together into the tire, eliminating the sequential process and reducing repair time while maintaining sealing effectiveness.
Solution Approach 2:
The puncture repair liquid is pre-mixed with compressed air in the mixing chamber before injection. This preliminary mixing action prepares the repair material in an optimized state (aerosol form) that enhances sealing efficiency and reduces the time required for effective puncture sealing.
2Reliability
If a large amount of puncture repair liquid is injected to seal the puncture, then the puncture can be sealed effectively, but the impact on sound-absorbing materials and sensors increases
Solution Approach 1:
The patent changes the physical state and delivery parameters of the puncture repair liquid by mixing it with compressed air to create an aerosol. This parameter change (from liquid to aerosol suspension) allows the liquid to be delivered more efficiently with reduced quantity, thereby minimizing impact on sensitive components while maintaining sealing effectiveness.
3Productivity
If puncture repair liquid containing agglomerates is injected, then the repair can proceed, but agglomerates may flow into the outlet and cause blockages or inefficiency
Solution Approach 1:
The mixing chamber acts as an intermediary between the liquid reservoir and the injection outlet. It provides a controlled environment where agglomerates can be managed and where the liquid-air mixture can be properly formed before discharge, preventing direct flow of agglomerates into the outlet system.
Solution Approach 2:
The mixing chamber changes the flow parameters of the puncture repair liquid by introducing compressed air and creating a mixed aerosol flow. This parameter change transforms the liquid flow characteristics, allowing agglomerates to be suspended and transported smoothly without clogging the outlet.
