Solution Overview

Problem

Conventional inflatable cushions lack thermal insulation and fail to evenly distribute thermal insulating elements, leading to reduced insulation effectiveness.

Innovation Solution

Incorporation of multiple thermal insulation layers, including an upper and lower thermal insulating layer and middle thermal insulating layers, with pull straps adhered to the surface layers to form air passages, ensuring even distribution and adherence of thermal insulating elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If thermal insulating elements are packed in the air passages, then thermal insulating effect is achieved, but the thermal insulating elements are easily displaced and cannot be distributed evenly

Engineering Contradiction:

Improvethermal insulating effectVSAvoiddistribution uniformity of thermal insulating elements

Core Design Contradiction:

TemperatureVSStability of the object's composition

Solution Approach 1:

The air passages are divided into multiple segments by the pull straps, and thermal insulating elements are placed in each segmented air passage. This segmentation prevents the elements from displacing to a single location and ensures even distribution throughout the cushion structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pull straps are pre-mounted between the upper and lower surface layers to define the air passages before thermal insulating elements are added. This preliminary action creates fixed boundaries that constrain and evenly distribute the thermal insulating elements when they are subsequently packed.

Inventive Principle:

Principle #10Preliminary action

2Temperature

If multiple thermal insulation layers are added, then thermal insulation effect is enhanced, but device complexity increases

Engineering Contradiction:

Improvethermal insulation effectVSAvoidstructure complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The pull straps serve multiple functions: they structurally support the cushion, define air passages for inflation, and simultaneously act as separators for thermal insulating elements. This multi-functionality allows multiple thermal insulation layers to be added without proportionally increasing overall structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Thermal insulating elements are nested within the air passages that are already defined by the pull straps. The upper and lower thermal insulating layers are positioned between the surface layers and pull straps, while middle thermal insulating layers are nested in the air passages, creating a nested structure that enhances insulation without adding external complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

An inflatable cushion includes an upper surface layer, a lower surface layer located under the upper surface layer, multiple pull straps mounted between the upper surface layer and the lower surface layer, and a thermal insulation module mounted between the upper surface layer and the lower surface layer. The pull straps are adhered to the upper surface layer and the lower surface layer, so that the inflatable cushion has an interior formed with multiple air passages defined between the upper surface layer, the lower surface layer, and the pull straps. The thermal insulation module includes an upper thermal insulating layer arranged between the upper surface layer and the pull straps, a lower thermal insulating layer arranged between the lower surface layer and the pull straps, and multiple middle thermal insulating layers received in the air passages.
