Laryngoscope Handle Insert With Slotted Light Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable laryngoscope handles with push button light sources face issues of movement or misalignment due to internal circuit completion, necessitating a stable and reliable illumination mechanism that maintains alignment and functionality.
Innovation Solution
A laryngoscope handle insert featuring a frame with a light source activation guide, a spring, and batteries, where the light source is slidable within a slot and activated by depressing a protrusion, ensuring continuous illumination without misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a push button light source is provided on the laryngoscope handle, then illumination functionality is achieved, but the light source is prone to movement or misalignment due to internal circuit completion
Solution Approach 1:
The patent introduces a slot as an intermediary structural element between the light source housing and the handle body. This slot guides and constrains the movement of the light source, preventing misalignment while allowing the push-button activation mechanism to function. The slot acts as a mediator that resolves the conflict between enabling light source movement for activation and maintaining stable alignment during operation.
2Ease of operation
If the light source is made slidable for activation, then ease of operation is improved, but reliability of continuous illumination is compromised
Solution Approach 1:
The patent implements a dynamic activation mechanism where the light source housing can slide within the slot during operation. The slot allows controlled movement for activation while maintaining constraints that ensure the light source returns to and maintains its proper position for continuous illumination. This dynamic design enables both ease of activation and reliability of continuous operation.
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
The insert provides stable and reliable illumination by maintaining the light source's alignment and functionality, eliminating the need for additional structural activation mechanisms within the handle.
Implementation Method 1
a spring, and one or more batteries therein wherein the one or more batteries are positioned between a top and a bottom of the spring

AI summary
An insert for a laryngoscope handle, the insert comprising a frame supporting a light source, a light source activation guide, a spring, and one or more batteries therein wherein the one or more batteries are positioned between a top and a bottom of the spring and wherein the light source activation guide is located on an upper end of the frame above the top of the spring. The light source activation guide has a slot extending along a length of the upper end of the frame wherein the upper end of the frame slidably receives the light source therein an protrusion on the light source is slidably retained in the slot.
