Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The trunk of a vehicle can become polluted with bacteria, viruses, dust, fungi, and odors from stored goods, posing a risk to user health and vehicle hygiene.
Innovation Solution
An automatic sterilizer system for vehicle trunks, equipped with sensors to detect goods and their changes, ultraviolet lamps for sterilization, air injection units for ventilation, and a control unit to manage these components, ensuring effective sterilization and odor removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual sterilization methods are used in the trunk, then some level of cleaning can be achieved, but the process is labor-intensive and may not effectively eliminate all bacteria, viruses, and odors
Solution Approach 1:
The system enables automatic sterilization through sensors that detect when the trunk is closed and automatically activate the ultraviolet lamp and air injection unit, eliminating the need for manual operation while ensuring consistent and effective sterilization of the trunk space
Solution Approach 2:
The patent replaces manual mechanical cleaning actions with automated systems including ultraviolet radiation for sterilization, air injection for odor removal, and sensor-based control mechanisms that operate without human intervention
2Volume of moving object
If the trunk space is increased to accommodate more goods, then storage capacity is improved, but the volume for potential contamination and odor generation increases
Solution Approach 1:
The air injection unit introduces oxygen-rich air into the trunk space, accelerating oxidation processes that help eliminate odors and contaminants, thereby managing harmful factors in larger trunk volumes used for storing goods such as fish and vegetables
3Reliability
If multiple sensors and sterilization components are added to the trunk system, then sterilization effectiveness is improved, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions by integrating sensor data processing, sterilization control, and ventilation management into a single controller, while the trunk space serves dual purposes as both storage area and sterilization chamber, reducing overall system complexity
