Sealing Agent Container Retention Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing and pump-up devices for pneumatic tires risk leaking of the sealing agent when the liquid agent container is mistakenly forcibly removed, leading to potential damage to the casing body.
Innovation Solution
A sealing and pump-up device design featuring a seal opening device with a retaining member that maintains the sealing agent container's mounted state, while a weaker fixing force of the seal opening device's fixing section allows for safe removal without leakage, utilizing a seal opening device with a female member and male member configuration, such as an indentation-shaped hole and pin, nut and bolt, or screw, to secure the device to the casing body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid agent container is fixed to the device main body by screwing the outflow section into the device main body, then the sealing agent can be fed into the tire, but the threaded portion may become loose when an operator mistakenly attempts to forcibly remove the container, leading to leakage
Solution Approach 1:
The device is divided into separate functional components: the liquid agent container, the seal opening device, and the device main body. The container can be independently removed without affecting the main device structure, allowing safe disposal or replacement without risking damage to the device body or leakage of sealing agent.
Solution Approach 2:
The seal opening device is extracted as a separate component that can be removed from the device main body. This allows the liquid agent container to be safely detached and disposed of without the risk of the threaded portion becoming loose and causing leakage, as the seal opening device serves as an intermediary that protects the container during removal.
2Stability of the object's composition
If the seal opening device is strongly fixed to the casing body, then the device structure is stable, but the device cannot be safely removed or adjusted
Solution Approach 1:
The fixing mechanism between the seal opening device and the casing body is designed to be dynamically adjustable. The device can be firmly fixed during operation to maintain structural stability, but can also be easily removed or adjusted when needed, providing both stability and adaptability through a reversible fixing mechanism.
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
Prevents leakage of the sealing agent and protects the casing body from damage during attempted removal of the sealing agent container by maintaining the mounted state and adjusting the fixing force as needed.
Implementation Method 1
a compressed air supply member that is connected to the seal opening device and supplies compressed air into the sealing agent container body sealed with the seal member

AI summary
A sealing and pump-up device capable of suppressing sealing agent contained in a sealing agent container body from leaking and preventing damage to a casing body even if an operator mistakenly attempts to remove the sealing agent container body. A connection body 70 is retained to a seal opening device 60 by fitting force between first claws 94A and a leg portion 36 and between second claws 96A and the leg portion 36. An operator might conceivably mistakenly attempt to remove a liquid agent container 18 from the seal opening device 60. However, the fixing force of the screw 128 in the circular hole 122 is determined by such factors as the shape of each member so as to be weaker than the sum of the fitting force (retaining force) between the first claws 94A and the leg portion 36 and the fitting force (retaining force) between the second claws 96A and the leg portion 3 6. Accordingly, fixing of the screw 128 in the circular hole 122 is released if an operator attempts to remove the liquid agent container 18 from the seal opening device 60, and the sealing agent 32 contained in the liquid agent container 18 can be suppressed from leaking and damage to the casing body 16 can also be prevented.
