Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable lighting devices attached to luggage or similar objects fail to maintain a consistent directional light output when the object is tilted, leading to inadequate illumination and visibility issues while performing tasks that require hands-free operation.
Innovation Solution
A lighting apparatus with an orientation sensor and processing unit that adjusts the light output parameters, such as brightness, direction, and color, to maintain the light in a desired orientation, even when the device is tilted, by selectively powering and deactivating multiple light sources based on the orientation sensor's input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional flashlight is attached to luggage or similar objects for hands-free operation, then the user can perform tasks with both hands, but the light output direction becomes unstable when the object is tilted
Solution Approach 1:
The lighting apparatus employs multiple light sources arranged in different orientations (horizontal, vertical, angled) that are dynamically activated based on the detected tilt angle. The system transitions from a static single-light-source design to a dynamic multi-source configuration, allowing the light output direction to adapt and remain stable regardless of the luggage's orientation.
Solution Approach 2:
The system changes the operational parameters of the light sources based on the tilt angle detected by the orientation sensor. Different combinations of light sources are activated depending on the angle, effectively changing the lighting configuration parameter to compensate for the tilt and maintain stable light output direction.
2Stability of the object's composition
If multiple light sources are used to maintain stable light direction, then the light output stability improves, but the device complexity increases
Solution Approach 1:
The lighting system is segmented into multiple independent light sources, each oriented in a specific direction (horizontal, vertical, angled). This segmentation allows the system to activate only the necessary light sources based on the detected tilt angle, managing complexity through modular design while achieving stable light output.
Solution Approach 2:
The multiple light sources serve multiple functions: they collectively provide stable light output in various orientations, and individually can be activated based on specific tilt conditions. This multi-functionality allows a single lighting apparatus to handle various orientation scenarios without requiring separate devices for each angle.
3Measurement precision
If an orientation sensor and processing unit are added to adjust light output, then the light direction control improves, but the device complexity increases
Solution Approach 1:
The orientation sensor continuously monitors the tilt angle of the luggage and provides feedback to the control unit. The control unit processes this orientation data and automatically adjusts the activation state of different light sources accordingly, creating a closed-loop feedback system that maintains stable light output without requiring manual intervention.
Solution Approach 2:
The lighting apparatus performs self-adjustment based on the detected orientation. The system automatically determines which light sources to activate based on the tilt angle, eliminating the need for manual adjustment by the user and reducing the operational complexity despite adding control electronics.

AI summary
A lighting apparatus having at least one set of light sources, a microprocessor, and an orientation sensor. The microprocessor and the orientation sensor are capable of maintaining the light source in a desired orientation. The lighting apparatus and devices having a lighting apparatus are capable of controlling the plurality of light sources to maintain the desired orientation of the lighting. The lighting apparatus may be connected to a device, such as a piece of wheeled luggage, stroller or hat, such that when the luggage is tilted the light source maintains an desired orientation relative to a fixed orientation, such as a horizontal orientation.
