Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun lights prone to accidental contact, leading to battery detachment and power interruption due to the pressing rod being easily touched by users or debris, affecting normal operation.
Innovation Solution
A gun light design with a rotatable light-emitting locking rod and locking elastic sheet that switches from a plane to an arc surface, minimizing accidental unlocking, combined with an adjusting mechanism for precise battery compartment access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pressing rod mechanism is used for battery replacement, then battery replacement speed is improved, but reliability deteriorates due to accidental contact causing unintended unlocking
Solution Approach 1:
The locking rod uses an arc-shaped contact surface instead of a flat pressing surface. The arc surface is designed to match the curvature of the elastic sheet, creating a geometric fit that prevents accidental disengagement while maintaining secure locking during normal operation
Solution Approach 2:
The locking mechanism employs asymmetric geometry where the arc surface of the locking rod complements the elastic sheet shape in one direction (locked state) but creates interference in the opposite direction (preventing unintended unlocking). This asymmetric design ensures that only deliberate rotational movement can change the locking state
2Reliability
If the locking mechanism is made more secure against accidental contact, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is divided into distinct functional segments: the elastic sheet provides resilient force, the arc surface provides geometric constraint, and the rotational locking rod provides controlled engagement. This segmentation allows each component to be simple while the combination achieves high reliability
Solution Approach 2:
The arc-shaped contact surface serves dual purposes: it provides the geometric constraint needed for reliability while maintaining a simple, continuous surface that requires no additional mechanical features or adjustment mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances battery replacement reliability by reducing accidental detachment, ensuring consistent power supply during use.
Implementation Method 1
Due to an elasticity of the locking elastic sheet, when the light-emitting locking rod is accidentally touched, the locking elastic sheet is less likely to knock up

AI summary
A gun light that facilitates battery replacement is provided, which includes a housing, a light-emitting module, a seat module, and a fixing mechanism. The housing is provided with a battery compartment, and the battery compartment is slidably fitted with a battery module; one side of the light-emitting module is rotatably connected to one end of the housing, and the other side of the light-emitting module is provided with a light-emitting locking groove. The seat module is connected to the other end of the housing. The fixing mechanism includes a locking component, which includes a locking elastic sheet and a light-emitting locking rod. The locking elastic sheet is fixedly connected to the housing. This application has the effect of reducing the risk of accidental contact causing the battery module to detach from the housing.
