Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld lighting devices often rely on a single power source, limiting their usability and convenience, especially in situations where one type of power source may be unavailable or depleted.
Innovation Solution
A dual power light source device that incorporates both rechargeable and non-rechargeable batteries, allowing users to switch between power sources and providing separate power outputs, with safety mechanisms to prevent incorrect usage and ensure proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single power source is used in handheld lighting devices, then the device structure remains simple, but the usability and reliability are limited when one type of power source is unavailable or depleted
Solution Approach 1:
The patent combines multiple power sources (rechargeable battery and non-rechargeable batteries) into a single handheld lighting device, allowing the device to draw power from either source. This merging of power sources resolves the contradiction by providing reliable power supply through multiple sources while integrating them into a unified device structure with automatic or manual switching capability.
2Adaptability or versatility
If multiple power sources are integrated into a handheld lighting device, then usability and reliability are enhanced, but the device structure becomes more complex
Solution Approach 1:
The handheld lighting device is designed to accept and utilize multiple types of power sources (rechargeable and non-rechargeable), making the device universal in terms of power supply options. The device can automatically detect and switch between power sources or allow manual selection, providing flexibility and adaptability while maintaining a relatively streamlined structure through intelligent power management circuitry.
3Duration of action of moving object
If rechargeable and non-rechargeable batteries are used together, then continuous operation is ensured, but safety risks such as accidental charging or short circuits may increase
Solution Approach 1:
The patent introduces a controller or power management circuit as an intermediary between the rechargeable and non-rechargeable batteries. This intermediary component intelligently manages power distribution, prevents incorrect charging attempts, detects battery types, and controls switching between power sources. By acting as a mediator, it ensures continuous operation while eliminating safety hazards associated with improper battery handling.
