Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common UV sanitizing apparatuses are used for sterilization, then germicidal effect is achieved, but the devices are bulky and complex making them unsuitable for everyday use
Solution Approach 1:
The patent employs a flexible bag structure made of UV-resistant material that can be easily carried and stored, replacing bulky rigid UV sanitizing apparatuses. The bag contains UV LEDs and reflective material, allowing sterilization of objects like masks, gloves, and personal items in a portable, everyday-friendly format.
Solution Approach 2:
The patent combines multiple functions into a single integrated bag system: UV radiation emitting means for sterilization, reflective material to enhance UV distribution, magnetic actuating means for safe operation, and a portable flexible body for storage and transport. This merging eliminates the need for separate sterilization devices.
2Reliability
If UV radiation is used for sterilization, then pathogen elimination is achieved, but health and safety concerns arise due to potential skin damage
Solution Approach 1:
The bag incorporates a magnetic actuating means that automatically activates the UV LEDs only when the bag is properly closed and positioned. This self-regulating mechanism prevents accidental UV exposure to users while ensuring effective sterilization when intended, eliminating the need for manual control and reducing safety risks.
Solution Approach 2:
The patent introduces a magnetic coupling mechanism as an intermediary between the user and the UV radiation source. The magnetic actuator responds to the metallic component in the bag closure, creating a safe interface that activates UV only under controlled conditions, thereby mediating between sterilization needs and user safety.
3Ease of operation
If manual cleaning methods are used for sanitization, then simplicity is maintained, but effectiveness and consistency are unreliable
Solution Approach 1:
The patent replaces manual mechanical cleaning actions with an automated UV radiation system. The UV LEDs emit germicidal radiation that automatically sterilizes objects placed in the bag, eliminating the need for manual scrubbing, rinsing, and drying steps while providing consistent and reliable sterilization results.
