Solution Overview
Problem
Existing vehicle stowage systems that allow vehicle interiors to be designated as package delivery destinations can compromise crime prevention due to unauthorized access.
Innovation Solution
A stowage system with a lock detection sensor, air conditioning device, and microprocessor that controls the fan operation based on lock status to secure a separate package room, ensuring packages are safely stored and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle interior is designated as a package delivery destination, then package delivery convenience is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The vehicle interior is segmented into a first package room (above the horizontal plane, accessible from vehicle interior) and a second package room (below the horizontal plane, accessible from outside vehicle). This segmentation allows packages to be delivered to a specific secure compartment without requiring access to the entire vehicle interior, thus maintaining delivery convenience while preventing unauthorized access to the vehicle interior.
2Object-affected harmful factors
If the second package room is provided below the horizontal plane and separated from the vehicle interior, then security against unauthorized access is improved, but device complexity increases
Solution Approach 1:
The stowage system combines multiple functions into an integrated structure: the first package room for general storage, the second package room for secure external delivery, the air conditioning device for temperature control, and the lock detection sensor for security monitoring. These components work together as a unified system managed by the microprocessor, achieving enhanced security without proportionally increasing complexity.
Solution Approach 2:
The lock detection sensor automatically detects when the second package room is locked and triggers the air conditioning device accordingly. The microprocessor autonomously controls the fan operation based on lock status, eliminating the need for manual intervention and reducing operational complexity while maintaining security.
3Use of energy by moving object
If the air conditioning device operates only when the second package room is locked, then energy efficiency is improved, but temperature control reliability may deteriorate
Solution Approach 1:
The system implements feedback control where the lock detection sensor continuously monitors the lock status of the second package room and provides this information to the microprocessor. The microprocessor then adjusts the air conditioning device operation accordingly - the fan operates when locked to maintain temperature, and stops when unlocked to save energy. This feedback mechanism ensures both energy efficiency and temperature control reliability.

AI summary
A stowage system includes: a lock detection sensor detecting an unlocked state where a package can be taken in and out of a second package room which is separated from both an interior space of a vehicle and a first package room formed above the horizontal plane extending along a floor of the interior space, and allows the package to be taken in and out from an outside of the vehicle, or a locked state; an air conditioning device; and a microprocessor. The air conditioning device forms a flow of air in the second package room by a fan. The microprocessor is configured to perform outputting an operation signal to the air conditioning device so that the fan operates when the lock detection sensor detects locking of the second package room in a state where the second package room stows the package.
