Insulated Carry Bag with Composite Thermal Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulated carry bags are large, bulky, and lack the fashion appeal typically sought by women, and they often struggle to maintain temperature requirements for both warm and cool items within a single bag.
Innovation Solution
A carry bag with a hollow body featuring a durable outer layer, insulative foam filling, and a heat reflective interior, along with a removable inner bag for enhanced temperature control, shock absorption, and adjustable apertures for easy access to contents, allowing for both cooling and warming of items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the bag uses thick insulative material to maintain temperature, then temperature control is improved, but the bag becomes bulky and less fashionable
Solution Approach 1:
The patent uses a composite insulation structure combining multiple materials: an outer waterproof layer, an intermediate insulating layer (foam or air pockets), and an inner reflective layer. This multi-layer composite approach achieves effective thermal insulation while minimizing the overall thickness and bulk of the bag, resolving the contradiction between temperature control and compact size.
Solution Approach 2:
The patent employs thin flexible insulating films and foams that provide adequate thermal protection without requiring thick rigid structures. The insulating layer is designed as a thin yet effective barrier that maintains temperature while keeping the bag compact and fashionable.
2Temperature
If the bag is designed for carrying warm items, then warmth maintenance is improved, but the bag cannot effectively carry cool items and vice versa
Solution Approach 1:
The patent designs the insulating system to be universally effective for both hot and cold items. The multi-layer structure with reflective, insulating, and waterproof layers works equally well to maintain both warmth and coolness, allowing the single bag to serve multiple temperature-related functions without requiring separate specialized bags.
Solution Approach 2:
The patent enables temperature control adaptation by allowing users to adjust the insulation configuration or add/removal of thermal layers based on whether carrying hot or cold items. The system can change its thermal parameters to suit different temperature requirements.
3Shape
If the bag has a simple structure for fashion appeal, then aesthetic quality is improved, but temperature insulation effectiveness is reduced
Solution Approach 1:
The patent integrates multiple functional layers (waterproof outer layer, insulating middle layer, reflective inner layer) into a unified structure that maintains a sleek, fashionable appearance from the outside while providing effective thermal insulation internally. The composite construction allows aesthetic simplicity externally with complex functionality internally.
4Strength
If the bag uses durable tough materials for the outer layer, then durability is improved, but the bag becomes heavier
Solution Approach 1:
The patent uses composite material construction where the outer layer provides durability and protection, while the inner layers provide insulation functions. This composite approach achieves both durability and light weight by assigning specific functions to specific layers rather than using a single heavy material for all purposes.
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
The bag effectively maintains temperature control for both warm and cool items, is compact and fashionable, and provides shock absorption, ensuring items remain at desired temperatures for extended periods.
Implementation Method 1
an insulative and pliable foam filling, and a tough and durable heat reflective layer
Implementation Method 2
a tough and durable heat reflective layer, that corresponds with the interior side wall of the body of the bag
Implementation Method 3
the body of the bag includes a shock absorbing layer in the base of the body, and the shock absorbing layer mitigates the impact when the bag is placed upon a hard surface

AI summary
The present disclosure relates to a carry bag, the carry bag includes a body having sidewalls and at least one handle disposed on the body. The body is hollow and dimensioned to receive one or more objects that are to be kept either cooler or warmer than the ambient temperature surrounding the body. The sidewalls of the body are constructed from an outer layer that corresponds to an exterior side wall of the body, a heat reflective layer that corresponds with an interior side wall of the body, and an insulative and pliable foam filling disposed between the outer layer and the heat reflective layer. The at least one handle is adapted to swing out of the way when not in use, so that the opening of the bag is unobstructed, thereby allowing the easy placement or removal of items to/from the bag.
