Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional molded, thin-walled plastic liquid containers lack durability and structural integrity, making them susceptible to damage during storage and transport, and they often fail to fit into various types of shipping boxes or crates, leading to inefficiencies in transportation and display.
Innovation Solution
A self-supporting liquid container design featuring a durable yet lightweight structure with enhanced corners and sides to prevent bumps and dents, allowing it to fit a wide variety of shipping boxes and crates, and optimizing display space with easy removal and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If thin-walled plastic containers are used, then weight is reduced and manufacturing cost is lowered, but durability and structural integrity deteriorate
Solution Approach 1:
The patent applies local quality by concentrating material and structural reinforcement at specific critical locations (corners, edges, base) rather than uniformly thickening the entire container wall. This allows the container to maintain lightweight thin walls in non-critical areas while having enhanced durability at stress-prone points through features like reinforced corners, edge protectors, and strengthened base structures.
Solution Approach 2:
The patent employs composite material strategies by combining thin plastic walls with additional protective elements such as corner protectors, edge reinforcements, and base strengtheners made from different materials or structural configurations. These composite structures provide enhanced strength and durability while maintaining the overall lightweight characteristic of the thin-walled design.
2Ease of manufacture
If conventional container configurations are used, then manufacturing simplicity is maintained, but adaptability to various shipping boxes and crates deteriorates
Solution Approach 1:
The patent achieves universality by designing the container with standardized dimensions and modular structural features that enable it to fit multiple types of shipping boxes and crates. The container's base structure, corner configurations, and overall geometry are optimized to be compatible with various standard shipping container types, allowing the same container design to be used across different transportation and storage systems without requiring custom modifications.
3Productivity
If lightweight thin-walled design is used, then transport efficiency is improved, but susceptibility to damage during transport increases
Solution Approach 1:
The patent implements beforehand cushioning by incorporating protective features such as reinforced corners, edge protectors, and strengthened base structures that are built into the container design before transport occurs. These pre-integrated protective elements act as cushioning and reinforcement mechanisms that prevent damage during handling and transportation, allowing the lightweight thin-walled design to maintain its transport efficiency while gaining damage resistance.
4Ease of operation
If handle is positioned on the corner, then ease of handling is improved, but structural stability during storage and display deteriorates
Solution Approach 1:
The patent applies local quality by concentrating structural reinforcement at the corner regions where the handle is attached. The handle itself is designed as a reinforced structural feature rather than a simple opening, with strengthened edges and integrated support structures that maintain corner integrity. This localized reinforcement at the handle position ensures both handling convenience and structural stability during storage and display.

AI summary
A thin-walled plastic container for storing liquids having a pour spout on a top and a handle disposed at a point near the pour spout to a point on a front of the container. In preferred embodiments, ridges are formed into portions of the corners and edges of the container and container body to add structural support. The characteristics of the present invention allow for enhanced storage and display capability, easier product transport, and increased durability.
