Multi-purpose Vehicle Deck Lamp Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-purpose vehicles inadequately illuminate the inside of the load carrier deck, especially in dark environments, due to external tail lamps and rear work lamps that fail to illuminate the peripheral areas effectively, leading to power consumption issues.
Innovation Solution
A multi-purpose vehicle design featuring a lamp embedded within the load carrier deck's constituting unit, powered by the vehicle's wiring network or battery-driven LED, with a switch operable from outside the deck to ensure efficient internal illumination and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If external tail lamps are used to illuminate the load carrier deck, then the structure is simple, but the illumination of the deck interior is insufficient
Solution Approach 1:
The lamp is integrated within the deck constituting unit structure itself, with the lamp housing formed as part of the wall panel. This nesting approach allows the illumination function to be embedded within the existing structural components, achieving good interior lighting without adding separate external mounting structures.
Solution Approach 2:
Instead of placing the lamp outside the deck and directing light inward, the invention inverts the approach by placing the lamp inside the deck constituting unit, with the light source positioned within the wall structure to illuminate the interior space from within the structure itself.
2Illumination intensity
If a rear work lamp mounted on the highest position is used, then the lamp can be positioned high, but it cannot illuminate the peripheral area of the front wall or area adjacent the bottom plate
Solution Approach 1:
The lamp is positioned locally within the deck constituting unit at a height that is optimized for illuminating specific areas. The local placement within the wall structure allows the light to be directed precisely where needed - along the walls and toward the bottom plate area - rather than using a single high-mounted lamp that cannot reach peripheral zones.
3Illumination intensity
If the lamp is provided inside the deck constituting unit, then the illumination coverage is improved, but the switch position becomes difficult to access
Solution Approach 1:
The switch is provided on an outer surface of the vehicle body, serving as an intermediary interface between the user and the lamp control. This allows the user to operate the lamp from outside the vehicle without needing to access the interior deck space, while the lamp itself remains positioned inside the deck constituting unit for optimal illumination.
