Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage lamps with integrated flashlight functionality require separate light sources and additional electric circuits, increasing complexity and weight.
Innovation Solution
A detachable luggage lamp design that integrates a flashlight and luggage lamp as a single light source, using a lamp housing with an optics system, a battery, and a stationary housing with an inclined reflective surface and hinge optic, allowing for dual functionality with a single power source and reduced parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flashlight and luggage lamp use separate light sources, then each function can be independently optimized, but the device complexity and weight increase
Solution Approach 1:
The patent implements a single light source that serves dual functions as both a flashlight and a luggage lamp. The lamp housing contains a lamp and battery that can operate independently as a flashlight, while also functioning as the illumination source when the housing is installed in the vehicle's luggage compartment as a luggage lamp. This eliminates the need for separate light sources and reduces overall device complexity.
Solution Approach 2:
The patent combines the flashlight and luggage lamp into a single integrated unit. The lamp housing is designed to be installed in the stationary housing within the vehicle, where it functions as a luggage lamp. When removed, the same housing functions as a portable flashlight. This merging of functions reduces the number of components, weight, and complexity while maintaining both functionalities.

3Device complexity
If a single light source is used for both flashlight and luggage lamp, then weight and complexity are reduced, but the appearance may be compromised
Solution Approach 1:
The patent applies different optical properties to different regions of the single light source system. The stationary housing includes a reflective surface that directs light in specific patterns when the lamp is installed as a luggage lamp. The optics are configured to provide appropriate beam patterns for both luggage lamp and flashlight functions, ensuring aesthetic and functional quality in each mode despite using a single light source.
4Device complexity
If a single light source is used for both flashlight and luggage lamp, then weight and complexity are reduced, but the illumination intensity for each function may be insufficient

The stationary housing includes a reflective surface that directs light in specific patterns when the lamp is installed as a luggage lamp. The optics are configured to provide appropriate beam patterns for both luggage lamp and flashlight functions, ensuring aesthetic and functional quality in each mode despite using a single light source.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables faithful performance of both luggage lamp and flashlight functions with reduced weight, cost, and improved appearance by using a single light source and efficient space utilization.
Implementation Method 1
a battery embedded in the lamp housing and supplying power to the lamp
Implementation Method 2
having an inclined reflective surface mounted on a surface thereof corresponding to the opening surface of the lamp housing

AI summary
A detachable luggage lamp is used as a luggage lamp by fixing a flashlight to a stationary part at ordinary times and used by separating the flashlight from the luggage lamp, if necessary. The flashlight of the luggage lamp may include a lamp housing having an opening surface formed on one side thereof, a lamp disposed in the opening surface, and a battery embedded in the lamp housing and supplying power to the lamp and a stationary part including a stationary housing having an accommodating part having a shape corresponding to the lamp housing and having an inclined reflective surface mounted on a surface thereof corresponding to the opening surface of the lamp housing, wherein the lamp housing and the stationary housing include a fastening member.
