Puncture Repair Kit Fixture for Inverted Sealant Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing puncture repair kits face challenges in reliably discharging puncture repair liquid when the container is in a pendent state from the tire valve due to tilting, which can hinder effective temporary tire repair.
Innovation Solution
A puncture repair kit equipped with a holding fixture that adjusts the attitude of the container to an inverted state via an injection hose, ensuring reliable discharge of the puncture repair liquid, featuring a length adjustment mechanism, double-sided tape or surface fastener connections, and stretchable materials to maintain stability and adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the injection hose is shortened to reduce weight and cost, then the puncture repair kit becomes lighter and cheaper, but the container may become pendent from the tire valve and tilt, making it impossible to sufficiently discharge the puncture repair liquid
Solution Approach 1:
A holding fixture is introduced as an intermediary component between the container and the injection hose. This fixture includes a holding portion that contacts the container and a curvature regulation portion that engages with the injection hose to control its curvature, thereby maintaining the container in the correct attitude without requiring a longer hose.
Solution Approach 2:
The holding fixture regulates the curvature parameter of the injection hose to maintain the container in the correct attitude. By controlling the curvature of the hose rather than its length, the system achieves reliable liquid discharge while keeping the hose short and the overall kit weight reduced.
2Length of moving object
If the container is allowed to be pendent from the tire valve via a short injection hose, then the hose length is reduced for weight and cost savings, but the container tilts and cannot discharge puncture repair liquid effectively
Solution Approach 1:
The holding fixture acts as a mediator that decouples the relationship between hose length and container attitude. It provides a mechanical means to control the container's orientation independently of the injection hose length, allowing short hoses to be used effectively.
Solution Approach 2:
Instead of solving the attitude control problem through linear hose length extension, the solution introduces a spatial dimension by using a holding fixture with specific geometric features (curvature regulation portion) that control the hose's three-dimensional curvature and the container's orientation.
3Reliability
If a holding fixture is added to maintain container attitude, then reliable discharge of puncture repair liquid is achieved, but the device complexity increases
Solution Approach 1:
The holding fixture is divided into distinct functional segments: a holding portion that contacts the container and a curvature regulation portion that engages with the injection hose. This segmentation allows each part to perform its specific function independently, simplifying the overall design and assembly.
Solution Approach 2:
The holding fixture can be designed as a simple replicated component with standardized features that can be easily manufactured and assembled. The curvature regulation portion, for example, may use simple geometric shapes or pre-formed structures that replicate the required curvature control function without complex mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The holding fixture effectively maintains the container in an inverted state, ensuring reliable discharge of the puncture repair liquid, even when the container is pendent from the tire valve, enhancing the completion of the injection operation and reducing weight and cost by stabilizing the hose curvature.
Implementation Method 1
The holding fixture holds an attitude of the container such that the container is in an inverted state in a state in which the container with the outlet being on a lower side is connected to the tire valve via the injection hose and is pendent from the tire valve

AI summary
A puncture repair kit includes a container in which puncture repair liquid is contained, a compressor that supplies compressed air, a pressurization hose connected between a pressurizing port of the container and the compressor, and an injection hose connected between an outlet of the container and a tire valve, and further includes a holding fixture that holds an attitude of the container such that the container is in an inverted state in a state in which the container with the outlet being on a lower side is connected to the tire valve via the injection hose and is pendent from the tire valve.
