Silicone Mouth-Held Flashlight for Comfortable Hands-Free Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hands-free flashlights are uncomfortable and potentially damaging when held in the mouth, often causing chipped teeth and difficulty in maintaining a secure grip, and they do not provide efficient hands-free operation for tasks requiring both hands.
Innovation Solution
A hands-free flashlight device with a silicone-covered housing that can be comfortably held in the mouth, featuring a neck strap, rechargeable LEDs, and a magnet for storage, allowing hands-free operation and illumination in dark spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cylindrical flashlight is placed in the mouth for hands-free operation, then the user can illuminate areas without using hands, but the flashlight causes discomfort and can chip teeth
Solution Approach 1:
The patent applies a silicone covering (flexible material) over the flashlight housing to create a soft interface between the rigid flashlight and the user's teeth. This flexible layer conforms to the mouth shape and prevents direct contact between hard surfaces and teeth, eliminating the harmful effect while preserving hands-free operation.
Solution Approach 2:
The flashlight combines different materials (rigid housing for structural integrity, silicone covering for comfort and protection) to achieve both functional requirements: maintaining structural strength for durability while providing a soft, safe interface for oral holding without tooth damage.
2Ease of operation
If a cylindrical flashlight is held in the mouth, then hands-free operation is achieved, but the flashlight is difficult to keep hold of and may fall out
Solution Approach 1:
The patent modifies the flashlight shape from cylindrical to contoured/curved design that follows the natural curvature of the mouth and lips. This curved geometry creates a better mechanical fit within the oral cavity, increasing friction and contact surface area to prevent the flashlight from slipping out during use.
3Illumination intensity
If a traditional flashlight is used for hands-free operation, then illumination is provided, but both hands are occupied and time is lost positioning the flashlight
Solution Approach 1:
The flashlight is designed to be self-positioning in the mouth through its contoured shape and flexible silicone covering, eliminating the need for manual adjustment. Once inserted, the device maintains its position automatically through the conformal fit, allowing users to immediately begin work without time-consuming positioning adjustments.
