Rotatable Pistol Light Head for Directional Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flashlights have limited adjustability of the lighting direction, requiring users to move their entire arm or body to achieve desired lighting angles, leading to user fatigue and limitations in usage scenarios.
Innovation Solution
A longitudinally gripping light device with a detachably connected gripping handle that allows for 360-degree adjustment of the lighting direction, enabling convenient and ergonomic use, as well as the ability to be hung or fixed in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user holds the flashlight horizontally with the light head exposed between thumb and index finger, then the flashlight can be easily held and basic lighting can be provided, but the rotation angle is limited and the lighting direction cannot be adjusted at a large angle
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotatable connection mechanism between the light head and the barrel, allowing the light head to rotate dynamically relative to the barrel. This enables the lighting direction to be adjusted at large angles while maintaining the ease of holding the flashlight horizontally, resolving the contradiction between ease of operation and adaptability.
2Adaptability or versatility
If the user moves the standing position or swings the entire arm to adjust the lighting direction in a large range, then the lighting direction can be adjusted, but the user's hand becomes prone to fatigue and soreness when held in an offset holding position for a long time
Solution Approach 1:
The rotatable connection mechanism allows the light head to be adjusted independently through a small wrist movement rather than requiring the user to swing the entire arm or move the standing position. This dynamic adjustment capability reduces user fatigue while maintaining large-angle lighting direction adjustment, resolving the contradiction between adaptability and ease of operation.
3Adaptability or versatility
If the conventional flashlight structure is used, then the flashlight can be held and moved freely, but it cannot be fixed at a certain area or easily hung at a certain place to hold the light source in the air
Solution Approach 1:
The patent applies segmentation by separating the flashlight into detachable components: a barrel, a light head with rotatable connection, and a handle assembly with a hook structure. This modular design enables the flashlight to be fixed at certain areas or hung at specific places while maintaining structural simplicity and ease of assembly/disassembly, resolving the contradiction between fixed positioning capability and device complexity.
