Reinforcing Member for Puncture Repair Liquid Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Puncture repair liquid holding containers face challenges in reducing weight and resource usage while maintaining pressure resistance due to the need for sufficient wall thickness to withstand compressed air.
Innovation Solution
Incorporating a reinforcing member with a higher tensile elastic modulus around the container's holding portion, covering at least 60% of its height, to enhance pressure resistance without increasing wall thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wall thickness of the puncture repair liquid holding container is increased to maintain pressure resistance, then the pressure resistance is improved, but the weight of the vehicle increases and resources are consumed
Solution Approach 1:
The patent applies composite materials by combining the resin material of the holding container with a reinforcing member made of a different material (metal, plastic, or paper) that has higher tensile elastic modulus. This composite structure allows the container to achieve sufficient pressure resistance with thinner walls, thereby reducing weight while maintaining strength
Solution Approach 2:
The reinforcing member is strategically disposed around the entire circumference of the holding portion at specific heights (covering at least 60% of the height from the center position) where structural weakness occurs. This localized reinforcement approach optimizes strength where needed while minimizing material usage and weight
2Strength
If the wall thickness of the puncture repair liquid holding container is increased to maintain pressure resistance, then the pressure resistance is improved, but the amount of material increases and resources are not saved
Solution Approach 1:
By using composite materials combining resin and reinforcing members, the patent achieves sufficient pressure resistance with reduced material quantity. The reinforcing member provides additional strength without requiring proportional increases in resin material, thus saving resources
Solution Approach 2:
The reinforcing member is placed only at specific critical regions (covering at least 60% of the height from the center position) rather than throughout the entire container. This localized approach reduces the total amount of material needed while maintaining pressure resistance
3Weight of moving object
If the wall thickness of the puncture repair liquid holding container is decreased to reduce weight, then the weight of the vehicle is reduced, but the pressure resistance becomes insufficient
Solution Approach 1:
The composite structure compensates for the reduced wall thickness by incorporating a reinforcing member with higher tensile elastic modulus. This allows the container to maintain sufficient pressure resistance even with thinner walls, enabling weight reduction
Solution Approach 2:
The reinforcing member is strategically positioned at critical heights where structural weakness occurs in cylindrical containers. This localized reinforcement ensures that pressure resistance is maintained at the weakest points despite overall wall thickness reduction

AI summary
A puncture repair liquid holding container includes a container main body provided with a holding portion that holds a puncture repair liquid and an opening, a cap mounted on the opening, and a reinforcing member made from a material having a tensile elastic modulus per unit cross-sectional area greater than that of a material constituting the holding portion. The reinforcing member is disposed around an entire circumference of the holding portion over at least a portion of the holding portion in a height direction.
