Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional puncture repair kits may cause partial coagulation of puncture repair fluid due to uneven mixing of compressed air and fluid, leading to inefficiencies in puncture repair.
Innovation Solution
A puncture repair kit with a mixing device that includes a mixing chamber, a first inlet flow path connected to a compressed air source, a second inlet flow path for puncture repair fluid, and an outlet flow path, featuring specific openings and configurations to ensure uniform mixing and efficient discharge of the mixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If compressed air and puncture repair fluid are supplied through a single flow path, then the device structure is simplified, but the mixing becomes uneven causing partial coagulation of the fluid
Solution Approach 1:
The single flow path is segmented into two separate inlet flow paths: a first inlet flow path for compressed air and a second inlet flow path for puncture repair fluid. This segmentation allows independent control of each fluid's flow, ensuring uniform mixing while maintaining relatively simple device structure.
Solution Approach 2:
A mixing chamber is introduced as an intermediary component between the two inlet flow paths and the outlet. The mixing chamber provides a dedicated space where compressed air and puncture repair fluid can mix uniformly before being discharged, preventing partial coagulation while keeping the overall device structure manageable.
2Productivity
If compressed air supply time is reduced, then puncture repair efficiency improves, but the puncture repair fluid may coagulate in the supply path
Solution Approach 1:
The system performs preliminary mixing of compressed air and puncture repair fluid in the mixing chamber before discharge. This preliminary action ensures the fluid is properly mixed and pressurized in advance, allowing for faster discharge and repair while preventing coagulation during the supply process.
Solution Approach 2:
The dual flow path design enables continuous and stable supply of both compressed air and puncture repair fluid to the mixing chamber. This continuous supply ensures the fluid remains in motion and properly mixed, preventing coagulation while maintaining efficient repair operation.
3Reliability
If the mixing chamber is made larger to improve mixing, then mixing uniformity improves, but the device size increases
Solution Approach 1:
The mixing chamber is designed with optimized local geometry and flow path configuration to achieve effective mixing in a compact volume. The flow paths are arranged to create appropriate turbulence and mixing zones within the chamber, ensuring uniform mixing without requiring a large overall device size.
