Inflatable Sleeve Projection for Dynamic Visual and Audio Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable products lack dynamic visual and interactive display capabilities, limiting their visual expression and playability.
Innovation Solution
A projection apparatus is integrated into an inflatable product, comprising a projection device and audio playback device within an inflatable cloth sleeve, wirelessly connected to an intelligent terminal, with various installation modes and features like focal length adjustment and temperature control, enabling dynamic video display and audio playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a projection device is integrated into an inflatable product, then the visual display effect and interactivity are improved, but the device complexity increases
Solution Approach 1:
The patent combines the projection device, audio playback device, and control systems into an integrated unit that is embedded within the inflatable product structure. The projection device includes components such as a light source, lens, and screen, while the audio device includes speakers and microphones, all merged into a single coordinated system housed within the inflatable structure, thereby achieving improved visual display effect while managing device complexity through unified integration
Solution Approach 2:
The inflatable product is designed to perform multiple functions simultaneously: it serves as both the structural body and the housing for the projection device, audio playback device, and control systems. The device can project images, play audio, and respond to user interactions, making it a multi-functional system that improves adaptability while the shared infrastructure reduces overall complexity
2Length of stationary object
If multiple components are integrated into the inflatable cloth sleeve, then the imaging distance and range are improved, but the manufacturing difficulty increases
Solution Approach 1:
The projection device is divided into separate functional modules including the light source module, lens module, screen module, and audio module, each of which can be manufactured and tested independently before being assembled into the final inflatable product. This segmentation allows for specialized manufacturing of each component while simplifying the overall assembly process
Solution Approach 2:
The projection device components are nested within the inflatable cloth sleeve structure, with the rigid projection components housed inside the flexible inflatable housing. The audio playback device and control systems are similarly nested within the same structure, creating a compact integrated unit that achieves long imaging distance without proportionally increasing manufacturing complexity

AI summary
A projection apparatus capable of being built into an inflatable product is provided and includes an inflatable cloth sleeve. A projection device and an audio playback device are fixedly connected inside the inflatable cloth sleeve, an imaging space is arranged between a front end of the projection device and the inflatable cloth sleeve, and the projection device and the audio playback device are wirelessly connected with an intelligent terminal. By combining the projection device with the inflatable cloth sleeve, the projection device has a larger imaging distance and a wider imaging range, and video pictures are dynamically displayed on the surface of the inflatable cloth sleeve, thus improving the display effect of the inflatable cloth sleeve. The projection device has a variety of installation and connection methods, which can meet different installation requirements, and can also play recordings or audio through the audio playback device, further improving interactive effect.
