Solution Overview
Problem
Existing infrared night vision systems for vehicles are limited in their application due to the inability to operate with visible light sources on trucks, excavators, tractors, small craft, boats, drones, and quadcopters, primarily because of different on-board voltage requirements and connection schemes, restricting their use in overland, water, and air transport.
Innovation Solution
The infrared night vision system includes a remote control device, a voltage switch for visible light sources, a brightness controller, and an activation control signal type switch, allowing for remote activation and operation with visible light sources of varying voltages and activation signals, enabling use on vehicles with different power systems and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the infrared night vision system is designed for standard passenger car voltage (12V), then it functions reliably in passenger cars, but it cannot be applied to trucks, excavators, tractors, small craft, boats, drones, and quadcopters with different voltage systems
Solution Approach 1:
The control unit is designed with multiple voltage input options (5V, 12V, 24V) and can automatically detect and adapt to different voltage systems. This allows the same infrared night vision system to be universally applied across passenger cars, trucks, excavators, tractors, small craft, boats, drones, and quadcopters without requiring separate system designs for each vehicle type.
Solution Approach 2:
The system incorporates a voltage switch that can change the operating voltage parameter of the visible light source based on the detected power system. The control unit automatically adjusts voltage parameters to match the connected vehicle's electrical system, enabling the system to function across different voltage environments without manual reconfiguration.
2Adaptability or versatility
If the system uses wired connection for control signals, then it ensures reliable signal transmission, but it cannot provide remote activation capability required for aircraft and remote vehicles
Solution Approach 1:
The control unit serves as an intermediary that accepts multiple types of control signals including wireless communications (Bluetooth, Wi-Fi, radio channels) and converts them into appropriate activation signals for the infrared light source and visible light source. This allows remote activation capability for aircraft and remote vehicles while maintaining reliable signal transmission through the control unit's signal processing and conversion functions.
3Adaptability or versatility
If the visible light source is switched directly to infrared range without voltage control, then the system is simple, but it cannot operate with visible light sources of different power voltages from various vehicles
Solution Approach 1:
The control unit incorporates a voltage switch that dynamically adjusts the power voltage supplied to the visible light source based on the detected vehicle electrical system (5V, 12V, or 24V). This dynamic voltage adjustment allows the system to operate with visible light sources from various vehicles with different power voltages while maintaining optimal performance and enabling successful switching to infrared range.
