Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing puncture repair kits require longer times for repair due to sequential injection of puncture repair liquid and compressed air, necessitating improvements for increased efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If puncture repair liquid and compressed air are sequentially injected into the punctured object, then the injection process is simple to control, but the time required for puncture repair becomes longer
Solution Approach 1:
The patent applies preliminary action by pre-mixing the puncture repair liquid and compressed air in a mixing chamber before injection. The liquid is supplied to the mixing chamber where it mixes with compressed air in advance, creating a ready-to-inject mixture that eliminates the need for sequential injection and reduces repair time.
Solution Approach 2:
The patent merges the liquid supply system and compressed air supply system into a unified mixing chamber where both substances are combined before injection. This merging allows simultaneous delivery of liquid and air through a single outlet, resolving the time loss associated with sequential injection while maintaining operational control.
2Productivity
If puncture repair liquid and compressed air are mixed in advance, then the repair efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the mixing device into distinct functional modules: a liquid supply unit with its own reservoir and control mechanism, a compressed air supply unit with regulator and valve, and a mixing chamber. This modular segmentation allows each component to perform its function independently, simplifying the overall design while enabling efficient pre-mixing.
Solution Approach 2:
The patent uses the mixing chamber as an intermediary component that receives both liquid and compressed air, facilitates their mixing, and then delivers the combined mixture. This intermediary structure simplifies the system by providing a dedicated space for mixing rather than requiring complex integration of supply systems.
3Productivity
If the mixing chamber is designed with multiple inlets and outlets, then the mixing efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies local quality by providing multiple inlets at different locations on the mixing chamber (liquid inlet separate from air inlet) and strategically positioned outlets. This localized arrangement of openings optimizes flow patterns and mixing efficiency within the chamber while maintaining a relatively simple overall chamber structure that remains easy to manufacture.
