Staggered Lighting Control for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable lighting devices with multiple light sources are cumbersome to control, requiring users to differentiate between various controls, which can be difficult in dark or stressful environments.
Innovation Solution
A lighting device with a user control that adjusts the brightness levels of multiple light sources in a staggered fashion, allowing different light sources to exhibit varying brightness levels based on a single control input, simplifying operation and reducing the need for multiple control mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate controls are provided for different light sources, then each light source can be independently adjusted, but the device becomes difficult and cumbersome to control
Solution Approach 1:
The patent combines multiple control functions into a single control mechanism. The user interface includes one control that can adjust the brightness of multiple different light sources (e.g., white LED, amber LED, red LED) sequentially or simultaneously, eliminating the need for separate controls for each light source while maintaining independent adjustment capability.
Solution Approach 2:
The single control mechanism is designed to perform multiple functions: it can adjust the brightness of different types of light sources, select between different lighting modes, and provide haptic feedback to indicate current settings. This universal control replaces what would traditionally require multiple specialized controls.
2Measurement precision
If multiple controls are provided for different light sources, then each light source can be precisely controlled, but the user must remember and differentiate between the controls
Solution Approach 1:
The control mechanism incorporates haptic feedback that changes based on the current lighting configuration. When the user interacts with the control, the haptic characteristics (such as resistance or vibration patterns) provide immediate feedback about which light source is currently being adjusted or what mode is active, eliminating the need for the user to remember which control does what.
Solution Approach 2:
The control mechanism provides visual feedback through LED indicators that change color or illuminate to indicate which light source is currently selected for adjustment. This allows the user to see which control function is active without having to remember, while still allowing precise brightness control of each light source.
3Adaptability or versatility
If multiple controls are provided for different light sources, then each light source can be independently adjusted, but the operation becomes complicated especially in dark or stressful environments
Solution Approach 1:
The patent merges multiple control functions into a single integrated control interface. This single control can adjust multiple different light sources and modes, reducing the number of physical controls the user must manipulate while maintaining the ability to independently adjust each light source's brightness and select different lighting configurations.
Solution Approach 2:
The control provides immediate haptic and visual feedback to confirm which light source is being adjusted and what the current settings are. This feedback mechanism simplifies operation in dark or stressful environments by eliminating the need for the user to mentally track which control does what, as the system actively communicates its state to the user.

AI summary
Various lighting devices and related methods of operation are provided which may be used to adjust brightness levels of a plurality of light sources in a staggered fashion in response to a single user control. In one example, a lighting device includes a plurality of light sources. Each light source is adapted to exhibit an associated current brightness level within a range of brightness levels associated with each light source extending from an associated minimum brightness level to an associated maximum brightness level. The lighting device also includes a user control adapted to selectively adjust the current brightness levels exhibited by the light sources in a staggered fashion such that the light sources exhibit different current brightness levels from each other over at least a range of positions of the user control.
