Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable cylindrical lights lack protection for LED light sources, making them prone to damage during use or storage, which affects user experience.
Innovation Solution
The inflatable cylindrical light design includes a light body with an inflatable cavity, a soft light cloth, and an opaque base cloth, with LED light sources fixed inside using a transparent fixing sheet, ensuring protection and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LED light sources are pasted and fixed on the outer side of airbags, then the structure is simple and easy to manufacture, but the LED light sources cannot be protected and are easily damaged due to collisions
Solution Approach 1:
The LED light source is nested inside the light body, which is enclosed by the inflatable cavity. This nested structure allows the LED to be protected within the flexible material while maintaining the portable and collapsible design of the inflatable light system.
Solution Approach 2:
The light body acts as an intermediary structure between the LED light source and the external environment. It provides a protective barrier that shields the LED from collisions and damage while allowing the light to function normally through the soft light cloth.
2Reliability
If LED light sources are placed inside the light body, then the LED light sources are protected from damage, but the structure becomes more complex
Solution Approach 1:
The light body is constructed from flexible materials including soft light cloth and opaque base cloth that form a thin-film enclosure. This flexible shell structure provides protection for the LED while maintaining the inflatable, collapsible nature of the device, avoiding the need for rigid complex structures.
Solution Approach 2:
The light body is segmented into distinct functional layers: the soft light cloth for light diffusion, the opaque base cloth for structural support and LED mounting, and the inflatable cavity for protection and shape maintenance. This segmentation allows each layer to perform its specific function while keeping the overall structure relatively simple.
