Solution Overview

Problem

Existing inflatable decorative systems with light strings face issues of instability and poor shape retention due to light strings being easily pulled or wobbly, whether hung outside or inside the inflatable structure.

Innovation Solution

An inflatable decorative system with a hollow bag body featuring internal first and second fixing portions, and reinforcing strips or lines that secure the light string system, allowing it to unfold into a preset shape and maintain stability after inflation, with options for various shapes like fireworks or Christmas tree designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the light string is hung outside the inflatable balloon, then it is easily accessible and simple to install, but it is easily pulled or falls from the balloon resulting in poor shape or destruction

Engineering Contradiction:
Improveease of installationVSAvoidshape stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The light string system is nested inside the inflatable bag body rather than being hung externally. The light string is arranged within the inflation chamber and fixed to the inner surface, protecting it from external forces while maintaining the decorative function.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The light string system is pre-arranged and fixed to the inner surface of the bag body before inflation. Multiple fixing portions are predetermined on the inner surface, and the light string is secured to these portions in advance, ensuring proper positioning and shape before the inflation process occurs.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the light string is fixed inside the inflatable lantern on a single light hanging strip, then it is protected from external damage, but it is easy to wobble inside the lantern and is unstable and single in shape

Engineering Contradiction:
Improveprotection from external damageVSAvoidshape stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The fixing structure is segmented into multiple fixing portions distributed on the inner surface of the bag body. The light string system is fixed to multiple separate fixing portions rather than a single strip, providing distributed support that prevents wobbling and enables diverse shape configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light string system transitions from being constrained to a single linear hanging strip to being fixed at multiple points across the two-dimensional inner surface of the bag body. This dimensional expansion allows the light string to form various stable shapes including fireworks patterns, Christmas trees, and other configurations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Stability of the object's composition

If multiple fixing portions are arranged on the inner surface of the bag body, then the light string system can be securely fixed and unfold into preset shapes, but the device complexity increases

Engineering Contradiction:
Improveshape stabilityVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The multiple fixing portions serve multiple functions: they secure the light string system, define preset shapes, and enable various decorative configurations. Each fixing portion is a simple structure (perforation or hook) that performs the dual role of mechanical attachment and shape definition, reducing the need for additional complex components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An inflatable decorative system includes an inflatable hollow bag body provided with an inflation port and a line hole, a plurality of first fixing portions having perforations or hook portions and arranged on an inner wall of the bag body, and a light string system. At least an end portion extends out of the bag body from the line hole, and the remaining portions are arranged inside the bag body and fixed among the plurality of first fixing portions so that the light string system is unfolded into a preset shape in the bag body after the bag body is inflated. The light string system can be directly hung among the plurality of fixing portions, and can also be fixed among the plurality of fixing portions by a reinforcing strip or reinforcing line.
