Cushion with heat preservation, cold insulation and freshness preservation functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soft cushions lack multifunctionality, particularly in outdoor settings, as they provide limited support and cannot accommodate food or maintain freshness, and are bulky and inconvenient to carry.
Innovation Solution
A cushion with an outer cover, inner core, and a containing bag with an insulation layer, featuring multiple opening and closing structures and flexible straps for versatile use as a pillow, backpack, or handbag, allowing for heat preservation, cold insulation, and freshness preservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional soft cushion is used for outdoor camping, then it provides support and rest function, but it is fluffy and bulky making it inconvenient to carry
Solution Approach 1:
The patent combines multiple functions into a single cushion product: support function (inner core), storage function (containing bag), and thermal insulation function (insulation layer). This merging eliminates the need to carry separate items for each function, reducing overall volume and improving portability while maintaining all necessary functionalities for outdoor camping
2Adaptability or versatility
If a traditional soft cushion is used, then it provides support function, but it lacks accommodation space for food and items
Solution Approach 1:
The containing bag is nested within the inner core of the cushion, creating a multi-layer structure where the bag is positioned inside the cushion body. This nested arrangement provides storage space without increasing external dimensions or structural complexity, allowing the cushion to maintain its simple appearance while offering additional accommodation functionality
Solution Approach 2:
The cushion is designed to perform multiple functions: support (inner core), storage (containing bag), thermal insulation (insulation layer), and freshness preservation (sealed containing bag). This multi-functionality approach allows a single product to replace multiple separate items, enhancing adaptability without proportionally increasing complexity
3Reliability
If a traditional soft cushion is used, then it provides support function, but it cannot preserve freshness or maintain temperature for food
Solution Approach 1:
The containing bag is constructed with composite materials including an insulation layer (such as foam or air-filled chambers) and a sealed structure. This composite construction provides thermal insulation and freshness preservation capabilities while maintaining a relatively simple overall structure that integrates seamlessly with the cushion design

AI summary
A cushion with heat preservation, cold insulation and freshness preservation functions is provided, relating to the technical field of home and outdoor patio leisure products. The cushion includes an outer cover and an inner core, as well as a containing bag located in the inner core. The bag body of the containing bag is provided with an insulation layer, and the opening of the containing bag corresponds to the first opening and closing structure of the outer cover. In outdoor camping and other scenarios, items that need heat preservation can be placed in the containing bag, which can reduce the number and volume of items needed to be carried, making them easy to carry, on the other hand, items such as food can also be insulated and kept fresh, making it convenient for users.
