Reconfigurable User Interface for Portable Lighting Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable lighting devices lack user-configurable interfaces, leading to modes that may not be optimally suited for individual user needs, and can be cumbersome to navigate, with potential for unintended mode changes due to power interruptions.
Innovation Solution
A multi-mode portable lighting device with reconfigurable user interfaces, allowing users to select from preset combinations and sequences of operational modes, and a switch module that enables direct mode selection without indexing through all modes, distinguishing between intended and unintended power interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pre-determined operating modes are provided in the user interface, then the device offers versatility for different user needs, but the device complexity increases and mode selection becomes cumbersome
Solution Approach 1:
The patent applies dynamics by making the user interface reconfigurable and adaptable based on user preferences. The system transitions from a static, fixed interface to a dynamic one where users can customize mode selections, access methods, and operational parameters. This allows the interface to adapt to different user needs without increasing inherent complexity, as the customization capability is software-based rather than hardware-based.
2Adaptability or versatility
If multiple pre-determined operating modes are provided, then the device serves diverse user needs, but the ease of operation decreases due to cumbersome navigation
Solution Approach 1:
The patent applies preliminary action by allowing users to pre-configure their preferred operating modes and interface settings before actual use. Users can set up custom mode selections, define preferred access methods (such as button presses or rotations), and establish default configurations. This preliminary setup eliminates the need to navigate through multiple modes during operation, as the system is already configured to present only the relevant modes for that user's needs.
3Adaptability or versatility
If mode selection requires indexing through all modes, then all modes are accessible, but the loss of time increases for users to reach desired modes
Solution Approach 1:
The patent applies local quality by allowing users to customize and prioritize specific modes based on their local needs and preferences. Instead of requiring users to navigate through all modes in a fixed sequence, the system enables users to define which modes are most relevant to their specific use cases and place them at the top of the selection hierarchy. This localized customization ensures that users can access their frequently needed modes immediately without time loss, while still maintaining access to all other modes if needed.
4Ease of manufacture
If the device provides fixed operational modes, then manufacturing is simpler, but the adaptability to individual user preferences is reduced
Solution Approach 1:
The patent applies universality by designing a single device platform that can serve multiple user preferences and operational needs through software configuration rather than hardware variations. The reconfigurable user interface allows one device to function as multiple specialized devices, with users able to program custom mode selections, define preferred access methods, and tailor the operational characteristics to match their specific needs. This multi-functionality approach maintains manufacturing simplicity while achieving high adaptability.

AI summary
A portable lighting device that provides different user interfaces that may be selected by the user. Each user interface may provide one or more operational modes, such as on mode, power save mode, strobe mode or momentary mode. After a user interface is selected, the user may select on of the operational modes. The portable lighting device may be a flashlight.
