Solution Overview
Problem
Existing portable UV sterilization containers are inefficient in sterilizing container-like items due to the placement of illumination devices, requiring items to be upright and consuming high energy for drying, which is inconvenient and wasteful.
Innovation Solution
A portable UV sterilization container with multiple LEDs fixed to the walls of the storage cavity, an inner circulation heating air duct, and a control system allowing for flexible sterilization and reduced energy use, including light-reflecting devices for improved UV distribution and a human-machine interface for various operation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the illumination device is disposed on the upper wall of the article storage cavity to achieve sterilization, then the sterilization function is provided, but the sterilized article needs to be placed upright which reduces stability and convenience for portable use
Solution Approach 1:
The single illumination device on the upper wall is segmented into multiple illumination devices distributed on different cavity walls (front, back, left, right, and/or top walls). This segmentation allows ultraviolet light to be emitted from multiple directions simultaneously, eliminating the need for upright placement while maintaining sterilization effectiveness.
Solution Approach 2:
The illumination approach transitions from a single-point source (upper wall only) to a multi-dimensional distribution system where light sources are placed on multiple walls. This dimensional expansion creates omnidirectional or multi-directional UV irradiation, allowing articles to be sterilized in any orientation.
2Ease of operation
If a heating air duct is provided to dry water stains on sterilized articles, then the drying function is achieved, but the drying process consumes high energy
Solution Approach 1:
The air duct system recovers and reuses the ultraviolet light energy that would otherwise be wasted. The cavity walls are designed to reflect UV light inward, and the air duct captures this reflected energy to assist in the drying process, converting otherwise discarded energy into useful thermal energy for moisture evaporation.
Solution Approach 2:
The system converts the potentially harmful scattered UV light that escapes from the storage cavity into a beneficial resource. By directing this stray UV radiation through the air duct onto articles, the system provides additional drying capability while utilizing energy that would otherwise be lost, thereby reducing overall energy consumption.

Implementation Method 2
the heating air duct can release hot air to the article storage cavity and dry the water stains remaining on the sterilized article
Implementation Method 3
the light-reflecting device is fixed to a cavity wall of the article storage cavity for reflecting the ultraviolet light emitted by the illumination device
