Flexible Container With Welded Reservoir And Insulated Bottom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible container devices for liquids, such as those used for hydration during outdoor activities, often fail to maintain temperature stability under extreme conditions and lack adjustable insulation options, leading to unwanted freezing or heating of contents.
Innovation Solution
A flexible container device with a rigid container top and bottom, and a flexible reservoir panel that can be sealed using a welding anvil, allowing for the attachment of a handle and adjustable insulation, enabling temperature control and insulation flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the reservoir panel is sealed using heat welding, then the sealing strength is improved, but the manufacturing complexity increases due to the need for welding anvils and precise seam alignment
Solution Approach 1:
The patent incorporates welding anvils directly into the molded container structure during initial manufacturing. This preliminary integration means the welding tools are pre-positioned and built-in, eliminating the need for separate welding equipment assembly and reducing manufacturing complexity while maintaining strong heat-welded seals
2Temperature
If thermal insulation is added to maintain liquid temperature, then temperature stability is improved, but the device complexity and weight increase
Solution Approach 1:
The patent applies thermal insulation selectively only to the container bottom where it is most needed for temperature maintenance, rather than insulating the entire container. This localized approach provides effective temperature stability while minimizing additional weight and complexity
Solution Approach 2:
The container utilizes composite construction with rigid plastic molded parts integrated with flexible reservoir panels. This composite structure inherently provides thermal properties while maintaining structural integrity, avoiding the need for separate insulation layers
3Strength
If the container is made entirely rigid for structural strength, then strength is improved, but the volume efficiency and flexibility worsen
Solution Approach 1:
The patent merges rigid molded container tops and bottoms with flexible reservoir panels to create a hybrid structure. The rigid parts provide necessary structural strength and attachment points, while the flexible panels conform to the container shape, maximizing volume efficiency and reducing material usage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
