Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Puncture repair liquid-holding containers face challenges in balancing squeezability and shape retention while preventing liquid degradation, especially at low temperatures, where increased thickness for shape retention compromises squeezability.
Innovation Solution
A puncture repair liquid-holding container design featuring a large-circumference section and a small-circumference section with a multilayered structure, including a gas barrier resin, where the small-circumference section facilitates easier gripping and deformation, ensuring efficient liquid delivery and preventing degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer wall thickness of the container is increased to maintain shape retention and prevent liquid degradation, then the container's shape retention and degradation prevention improve, but the squeezability of the container deteriorates
Solution Approach 1:
The container body is divided into two distinct sections: a large-circumference section and a small-circumference section. The small-circumference section has thinner wall thickness designed for easy squeezing, while the large-circumference section maintains sufficient thickness for shape retention and protection. This segmentation allows different parts of the container to have different thickness characteristics optimized for their specific functions.
Solution Approach 2:
Different wall thicknesses are applied to different sections of the container based on local functional requirements. The small-circumference section has reduced wall thickness to facilitate squeezing operations, while the large-circumference section maintains greater thickness for structural integrity and liquid protection. This local differentiation resolves the contradiction between overall shape retention and localized squeezability.
2Reliability
If the outer wall thickness of the container is increased to prevent puncture repair liquid degradation, then the degradation prevention improves, but the squeezability of the container deteriorates
Solution Approach 1:
The container is segmented into regions with different protective requirements. The small-circumference section prioritizes user interaction and dispensing efficiency with thinner walls, while the large-circumference section provides enhanced protection against liquid degradation through greater thickness, particularly important for the bulk liquid storage area.
Solution Approach 2:
The container employs a multilayered structure combining different material layers including gas barrier resin. This composite construction provides effective degradation prevention through the barrier properties of specific layers, allowing the overall wall thickness to be optimized - thin enough for squeezability in critical sections while maintaining protective functionality through the multilayer design.
3Ease of manufacture
If the container is designed with uniform circumference to simplify manufacturing, then the manufacturing complexity reduces, but the liquid delivery efficiency and user grip comfort deteriorate
Solution Approach 1:
The container body is segmented into large-circumference and small-circumference sections, creating a non-uniform shape that optimizes both user interaction and liquid delivery. The small-circumference section provides a comfortable grip area and efficient compression zone, while the large-circumference section accommodates the bulk liquid volume. This segmentation improves delivery efficiency without significantly complicating manufacturing processes.
Solution Approach 2:
The container design transitions from a two-dimensional uniform cross-section to a three-dimensional variable cross-section along its length. This dimensional variation allows the circumference to change along the container body, creating optimized zones for gripping and dispensing while maintaining manufacturability through standard molding techniques that can accommodate gradual dimensional changes.

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 container efficiently injects puncture repair liquid into tires with improved squeezability and shape retention, preventing liquid degradation by maintaining sufficient outer wall thickness and using a multilayered structure with a gas barrier resin.
Implementation Method 1
the puncture repair liquid within the container migrates to the large-circumference section on the opening side having the relatively large circumference when the container is inverted to inject the puncture repair liquid
