Puncture Repair Liquid Container Visual State Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing puncture repair liquid holding containers lack a simple method to confirm the supply state of compressed air and puncture repair liquid, leading to difficulties in determining if the closing plugs are properly removed to open the flow channels.
Innovation Solution
A puncture repair liquid holding container with a cap featuring a straight and branch portion outflow channel, where a closing plug with a projection portion is slidably inserted, allowing easy confirmation of the open state through visual inspection of the projection's amount and color difference, and a spring member for automatic reclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light-emitting diodes or buzzers are provided as abnormal-state alarming units to inform abnormalities, then the ability to detect supply state abnormalities is improved, but the device complexity increases due to required control circuits
Solution Approach 1:
The patent replaces electronic detection systems (light-emitting diodes, buzzers, control circuits) with a simple mechanical visual indicator system. The projection portion on the closing plug provides direct visual confirmation of the flow channel state through its position relative to the cap surface, eliminating the need for complex electronic control circuits while maintaining reliable abnormality detection capability
Solution Approach 2:
The patent creates a visual copy or representation of the internal flow channel state through the projection portion's external position. The projection portion's position (inside or outside cap surface) directly reflects the closing plug's position and thus the flow channel state (closed or open), providing simple visual information about the internal state without requiring complex sensing systems
2Ease of operation
If the container interior state is made visible to confirm closing plug position, then the ease of operation is improved, but the device complexity increases with additional components
Solution Approach 1:
The patent merges the closing plug structure with a visual indicator function by integrating the projection portion directly onto the closing plug. This combines the sealing function and the indication function into a single component, allowing flow channel state confirmation without adding separate indicator components to the container structure
Solution Approach 2:
The closing plug serves multiple functions: it seals the flow channel when in the closed position and simultaneously provides visual indication of the flow channel state through its projection portion. This multi-functionality eliminates the need for separate indication mechanisms, maintaining simple container structure while improving ease of operation
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
Enables reliable confirmation of the outflow channel's open state without increasing complexity, preventing liquid leakage and ensuring proper operation, with high reliability and ease of use.
Implementation Method 1
Closing plugs are inserted to the flow channels to prevent the leaking of puncture repair liquid from the flow channels during storing. Such closing plugs slide through the flow channels by the pressure of the compressed air fed to the container interior during puncture repair to move to a predetermined position (open state) to open the flow channels.
Implementation Method 2
the closing plug including a projection portion projecting toward the closed end of the straight portion and being slidable in the through-hole

AI summary
Provided is a puncture repair liquid holding container. An outflow channel in a cap mounted to an opening portion of a container body for discharging the puncture repair liquid inside the container interior to a container exterior includes a straight portion including an open end opening toward inside the container body and a closed end terminating inside the cap, and a branching portion including a communicating end communicating with an intermediate area of the straight portion and an open end opening toward the container exterior. A through-hole is at the closed end of the straight portion. A projection on a closing plug and slidably inserted to the straight portion is slidably inserted to the through-hole. States are switchable between open and closed states in which the outflow channel is opened and closed by the closing plug and the projection is positioned in the through-hole or projects from the through-hole.
