Multipolar Cell Power Supply Device for Flashlight Thermal Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flashlights have high manufacturing costs and reduced service life due to the use of a tube body or conductive sheet as an electrode and the control circuit's proximity to the high-temperature light source, which increases assembly complexity and reduces production efficiency.
Innovation Solution
A multipolar cell power supply device with a shell, electric core, positive and negative pole power distribution units, and a controller that eliminates the need for a tube body or conductive sheet as an electrode, with the controller positioned at the rear to avoid heat damage, simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control circuit is disposed on the front end of the flashlight near the light emitting body, then the control function is achieved, but the high temperature heat from the light emitting body causes damages to the control circuit and reduces service life
Solution Approach 1:
The controller is extracted from the front end assembly and relocated to the rear end of the flashlight tube body, separating it from the high-temperature light emitting body. This spatial extraction eliminates the harmful thermal impact on the control circuit while maintaining its control functions.
Solution Approach 2:
The controller is positioned in a different spatial dimension (rear end) rather than at the front end near the light source. This dimensional relocation along the longitudinal axis of the flashlight creates thermal separation without compromising control functionality.
2Ease of manufacture
If a tube body or conductive sheet is added to the flashlight as an electrode, then the battery can be applied to the flashlight, but the manufacturing cost increases and assembly becomes inconvenient reducing production efficiency
Solution Approach 1:
The shell of the battery is merged with the flashlight structure by directly disposing the battery inside the flashlight tube body. The battery shell serves as part of the structural housing, eliminating the need for separate tube body or conductive sheet components while maintaining electrical functionality.
Solution Approach 2:
The battery shell is designed to serve multiple functions: it provides structural housing for the battery and simultaneously acts as part of the flashlight's structural framework. This multi-functionality eliminates the need for additional dedicated tube body or conductive sheet components.
