Rotating Flashlight Shaft Assembly for Adjustable Lighting Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flashlights have a limited lighting angle due to the fixed connection between the control assembly and the lamp head assembly, making them inconvenient for various shooting applications.
Innovation Solution
A flashlight design featuring a rotating shaft assembly with a rotating member that allows the lamp head assembly to rotate around a central axis, enabling adjustable lighting angles and improved convenience by allowing the light emitting surface to be illuminated in different directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control assembly and lamp head assembly are fixedly connected, then the structure is simple and stable, but the lighting angle is narrow and convenience is reduced
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed connection between the control assembly and lamp head assembly into a rotatable connection. The lamp head assembly is connected to the rotating shaft assembly, allowing it to rotate around a central axis. This dynamic connection enables the lighting angle to be adjusted while maintaining structural simplicity through standardized rotating components.
2Adaptability or versatility
If the lamp head assembly is fixed in position, then the manufacturing precision is easy to maintain, but the adaptability to different shooting applications is limited
Solution Approach 1:
The patent applies segmentation by dividing the flashlight into distinct functional modules: the control assembly, the rotating shaft assembly, and the lamp head assembly. The rotating shaft assembly acts as an independent intermediate component that enables angular adjustment. This modular segmentation allows the lamp head to be positioned at different angles while each module maintains its own manufacturing precision standards.
3Adaptability or versatility
If a rotatable connection is added to enable angle adjustment, then the lighting angle and convenience are improved, but the device complexity increases
Solution Approach 1:
The patent applies the merging principle by integrating the rotating shaft assembly as a core component that combines multiple functions: it serves as both the rotation mechanism and the structural support for the lamp head assembly. The rotating shaft assembly merges the functions of angle adjustment and positional support into a single integrated component, reducing the overall device complexity despite adding rotatable functionality.
