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 actuate these components based on sensed conditions, to sterilize and ventilate the trunk effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If goods are stored in the trunk for vehicle use, then the trunk can store various goods such as traveling supplies and shopping items, but bacteria, viruses, dust, fungi, and odors can be generated from the goods, polluting the trunk and posing health risks to users
Solution Approach 1:
The system performs preliminary sterilization actions by detecting goods in the trunk and automatically activating the ultraviolet lamp and air injection unit to sterilize and ventilate the trunk, preventing contamination before it affects users
Solution Approach 2:
The goods sensor continuously monitors the presence and state of goods in the trunk, providing feedback to the control unit which adjusts the sterilization and ventilation operations accordingly, ensuring the trunk remains hygienic while accommodating stored goods
2Object-affected harmful factors
If an automatic sterilizer system is installed to remove bacteria, viruses, dust, fungi, and odor, then the trunk hygiene and user safety are improved, but the device complexity and cost increase
Solution Approach 1:
The control unit integrates multiple functions including goods detection, sterilization control, and ventilation management into a single system, allowing the trunk to perform both storage and automated hygiene maintenance without requiring separate independent systems
Solution Approach 2:
The system enables the trunk to automatically monitor and maintain its own hygiene status through integrated sensors and actuators, eliminating the need for manual intervention and reducing the complexity of external control systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system automatically sterilizes and ventilates the trunk, reducing bacteria, viruses, dust, and odors, ensuring a hygienic and secure travel environment and enhancing vehicle merchantability.
Implementation Method 1
an ultraviolet lamp for irradiating ultraviolet rays to an inside of the trunk
Implementation Method 2
an air injection unit for injecting air to the inside of the trunk through an air nozzle
Implementation Method 3
a ventilator opening/closing module for opening/closing a rear camera module installed in a ventilator formed in the trunk and ventilating the inside of the trunk through the ventilator
