Adaptive Lighting for Mobile Dispensing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable dispensing devices face challenges in providing adequate illumination for reading text and locating objects in low-light conditions, especially when the second set of lights intended for illuminating the dispensing surface is unusable due to the device's inability to constrain its contents, leading to spills.
Innovation Solution
A mobile dispensing device equipped with three or more light sets, where one set provides ambient illumination, another set illuminates the dispensing surface during use, and a third set offers focused illumination for non-dispensing situations, controlled by a processor-based illumination system that detects motion and tilting to adjust lighting accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the second set of lights is used to illuminate the dispensing surface, then reading and object location are improved, but contents spill outside the device
Solution Approach 1:
The patent applies dynamics by making the lighting system adaptive to the device's orientation state. The processor detects when the device is tilted beyond a threshold angle and dynamically switches from the second light set (for reading) to the first light set (for dispensing illumination), preventing spills while maintaining reading capability when appropriate
Solution Approach 2:
The patent implements feedback through the processor that continuously monitors the device's tilt angle and automatically adjusts which light set is active. This closed-loop control ensures that the second light set is only used when the device is in a stable, non-dispensing orientation, eliminating the harmful spilling effect
2Illumination intensity
If the first set of lights provides diffuse lighting, then ambient illumination is improved, but focused illumination for reading remains insufficient
Solution Approach 1:
The patent segments the lighting function into two distinct light sets: the first light set provides diffuse ambient illumination for general visibility, while the second light set provides focused illumination specifically for reading menus and locating objects. This segmentation allows each light set to optimize its specific function without compromise
3Illumination intensity
If two sets of lights are used, then illumination coverage is improved, but device complexity increases
Solution Approach 1:
The patent achieves multi-functionality by having the processor serve dual roles: it both controls the illumination system and detects the device's tilt angle. This universal approach allows the system to provide comprehensive illumination coverage with minimal additional complexity, as the existing processor handles both control and sensing functions

AI summary
A mobile dispensing device comprising at least three or more light sets with each light set having a different region associated with the device and at least one of the lights sets is configured to provide illumination when the device is in the act of dispensing and least one of the other light sets is configured to provide focused illumination when the mobile dispensing device is not involved in the act of dispensing. The device further being configured to read one or more inputs/sensors that are used to determine a lighting condition that either overrides, supplements or is implemented independently of any lighting condition associated with the detected motion and tilting angle of the device.
