Vehicle Carrier Box Illumination Device with Automatic Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle carrier boxes lack an uncomplicated and versatile lighting solution for illuminating the interior, especially during loading and unloading under poor lighting conditions, and the lid often blocks external light when open.
Innovation Solution
An illumination device is integrated with the support device of the vehicle carrier box, featuring a light source, a reed switch, and a magnet for automatic switching, allowing the light to turn on when the lid is open and off when closed, with no additional mounting required, using a standard interface that engages with the support device's arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an illumination device is added to light the interior of the vehicle carrier box, then the lighting capability is improved, but the device complexity increases due to additional mounting requirements
Solution Approach 1:
The illumination device is merged with the support device by integrating the mounting interface into the existing support structure. The first housing of the illumination device engages with the support device through a standardized interface, combining two separate functions (support and illumination) into a unified system without requiring additional mounting components.
Solution Approach 2:
The support device is designed to serve multiple functions: it provides mechanical support for the lid and simultaneously serves as a mounting structure for the illumination device. The standardized interface allows the same support device to accommodate both structural and lighting functions, reducing overall system complexity.
2Ease of operation
If a manual switch is used for the illumination device, then the ease of operation is improved, but the loss of energy increases due to unnecessary lighting when the box is closed
Solution Approach 1:
The system uses a magnet and reed switch to create an automatic feedback mechanism. When the lid is opened, the magnet moves away from the reed switch, triggering the light to turn on. When the lid is closed, the magnet returns to the reed switch position, automatically turning the light off. This feedback loop eliminates energy waste by ensuring lighting only occurs when the box is open.
Solution Approach 2:
The illumination device automatically detects and responds to the lid position without requiring manual intervention. The magnet attached to the moving lid portion and the reed switch on the stationary housing create a self-actuating system that turns the light on or off based on the physical state of the box, eliminating the need for manual switching while conserving energy.
