Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for indicating parking space occupancy status only inform drivers of availability without assisting vehicle maneuvering or enhancing visibility, especially in dark conditions.
Innovation Solution
A compact module integrating detection, signaling, and illumination means, with programmable control for adjustable lighting, using ultrasonic distance sensors and LED illumination to provide sufficient and directed lighting for comfortable parking and exit, connected to a communications network for centralized control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If illumination means are added to assist vehicle maneuvering, then visibility and ease of operation improve, but device complexity increases
Solution Approach 1:
The patent combines multiple functions (occupancy detection, status signaling, and illumination) into a single integrated device mounted on the parking structure. The detection means, signaling means, and illumination means are coordinated by a control unit within the same system, eliminating the need for separate devices and reducing overall system complexity despite adding functionality.
Solution Approach 2:
The device performs multiple functions simultaneously: detecting vehicle occupancy using sensors, indicating status with visual signals (LEDs), and providing illumination for driver visibility and maneuvering. This multi-functional approach consolidates what would otherwise require separate systems into one universal parking space management device.
2Use of energy by moving object
If illumination is activated only when needed, then energy consumption decreases, but visibility assistance may be insufficient
Solution Approach 1:
The illumination means are activated periodically based on detected occupancy events rather than continuously. The control unit receives signals from detection means and activates illumination only during relevant periods (when a vehicle is present and maneuvering is needed), automatically deactivating when the space is empty, thus matching energy consumption to actual operational needs.
Solution Approach 2:
The system uses feedback from detection means (sensors) to control illumination activation. When sensors detect a vehicle occupying the parking space, the control unit activates the illumination means to provide visibility assistance. When no vehicle is detected, illumination is deactivated, creating a closed-loop system that adjusts energy consumption based on real-time conditions.
