Multimode Lighting Control with Sensor-Based Output and Runtime Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ANSI-PLATO FL-1 standard for flashlights does not accurately convey light output performance due to inconsistent mode labels and user interfaces, leading to consumer confusion and incentives for manufacturers to manipulate lumen values and runtime, failing to provide a clear understanding of how flashlights perform between advertised endpoints.
Innovation Solution
A multimode portable lighting device with adjustable lighting modes based on internal and external sensors, including constant, boost, and automatic modes, to maintain consistent light output and extend runtime, while incorporating user-friendly interfaces for mode selection and battery management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If manufacturers use high lumen values to attract consumers, then marketing appeal is improved, but light output performance accuracy deteriorates due to manipulation of lumen values
Solution Approach 1:
The patent implements feedback mechanisms through standardized icons that provide real-time information about actual light output performance. The system continuously monitors and displays accurate lumen values, beam distance, and runtime information, preventing manufacturers from manipulating performance claims while giving consumers transparent feedback about actual product capabilities.
Solution Approach 2:
The patent changes the parameters used for product comparison by establishing standardized measurement criteria for lumen output, beam distance, and runtime. These standardized parameters replace the previously manipulated marketing claims, providing an objective basis for comparing flashlight performance across different products.
2Adaptability or versatility
If manufacturers use inconsistent mode labels (turbo, high, medium, low, ultra-low), then product differentiation is improved, but consumer understanding deteriorates
Solution Approach 1:
The patent applies local quality by assigning specific, standardized meanings to each lighting mode label. Instead of allowing manufacturers to define modes arbitrarily, the system establishes consistent definitions for each mode (e.g., high beam mode, low beam mode, spotlight mode, flood mode) that convey precise information about the actual lighting characteristics and intended use cases.
Solution Approach 2:
The patent creates a universal labeling system that works across all flashlight products. The standardized mode labels serve multiple functions: they indicate beam type, intensity level, and intended application simultaneously, providing consumers with comprehensive understanding through a consistent framework that can be applied to any product in the marketplace.
3Measurement precision
If the FL-1 standard provides test criteria for beam distance and light output, then measurement capability is improved, but consumer confusion persists due to inconsistent user interfaces
Solution Approach 1:
The patent segments the user interface into standardized functional areas that consistently display specific information: mode selection, lumen output indicators, beam distance measurements, and runtime information. This segmentation creates a predictable interface structure across different products, making it easier for consumers to understand and operate flashlights regardless of manufacturer.
4Illumination intensity
If manufacturers focus on maximizing light output, then illumination performance is improved, but runtime deteriorates due to battery depletion
Solution Approach 1:
The patent implements dynamic lighting modes that allow the flashlight to adapt between high-intensity short-duration operation and lower-intensity long-duration operation. The system provides multiple operational states including high beam mode for maximum illumination with reduced runtime, low beam mode for extended runtime with reduced intensity, and spotlight/flood modes that balance illumination and duration based on specific application needs.
Data Source
AI summary
A multimode lighting system is disclosed. Due to industry standards, manufacturers of lighting devices are incentivized to create high initial light outputs that drop off quickly. Portable lighting devices with multiple modes of operation that can maximize light output and runtime according to industry standards (e.g., FL-1) as well as other lighting modes with more consistent light output over the device runtime. Lighting modes may be adjusted automatically based on sensor input. In an extreme mode, light output may be adjusted based on the temperature of the lights. Automatic modes may be adjusted based on ambient lighting or distance to a target. Lifecycle adjustments may be made to output current levels to obtain consistent light output throughout the lifecycle of lights by adjusting lighting based on accumulated usage.
