Flashlight Barrel Storage Compartment Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flashlights lack a convenient and waterproof storage compartment for additional items such as spare bulbs or other small accessories, which can be useful for various applications but are not inherently provided in existing designs.
Innovation Solution
A cylindrical storage compartment with a design matching the outer diameter and threading of a flashlight barrel, allowing it to integrate seamlessly and provide a sealed space for storage, which can be used with existing or new flashlights, and can be configured for stealth or visibility depending on the user's needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a storage compartment is added to the flashlight, then storage capability is improved, but device complexity increases
Solution Approach 1:
The storage compartment is designed to fit inside the existing flashlight barrel, utilizing the internal space that would otherwise be unused. The compartment nests within the barrel structure, and the tail cap threads into the compartment to seal it, creating a nested configuration that adds storage without requiring external additions or significant structural changes to the flashlight.
Solution Approach 2:
The storage compartment is designed with universal compatibility, featuring threading that matches the existing barrel and a seal interface that works with the tail cap. This allows the same compartment design to be used with various flashlight models, providing multi-functionality and broad adaptability without requiring model-specific customizations.
2Reliability
If the storage compartment is sealed waterproof, then protection of items is improved, but manufacturing precision requirements increase
Solution Approach 1:
The sealing function is extracted from the main compartment structure and concentrated into a separate, dedicated sealing element. The tail cap includes a seal that interfaces with the compartment opening, and the compartment itself has a dedicated seal interface. This separation allows the sealing mechanism to be optimized independently, reducing the overall manufacturing precision requirements for the entire assembly.

AI summary
A storage compartment for a flashlight with a cylindrical barrel, a tail cap and a conductive spring fitted to the tail cap. The conductive spring is removed from the tail cap and fitted to the barrel end of a cylindrical compartment which has an outer diameter substantially the same as that of the barrel and then the tail cap is threaded into a tail cap end of the cylindrical compartment, thus sealing off an inner compartment.
