Microphone Light Guide Member for Ring-Shaped Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional microphones with light-emitting portions for visual operation state recognition suffer from low light use efficiency and high power consumption due to the limited angle of light emission, requiring multiple light sources which increase costs and power usage.
Innovation Solution
A tubular microphone design incorporating a light source positioned near the front end, a light guide member with a protrusion for efficient light distribution, and a holding member that fixes the light source and guide member to the microphone case, allowing light to be emitted in a ring shape around the periphery, enhancing visibility and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources are used to emit light in the entire periphery of the microphone case, then the visual recognition angle is improved, but the cost and power consumption increase
Solution Approach 1:
A light guide member is introduced as an intermediary component between the light source and the microphone case periphery. The light guide member receives light from a single light source and distributes it along the entire periphery of the microphone case, achieving wide visual recognition without requiring multiple light sources. This resolves the contradiction by using an intermediate structure to amplify and distribute light efficiently.
Solution Approach 2:
The light guide member extends light distribution from a point source (single light source) to a linear distribution along the periphery of the microphone case. By transforming the light distribution pattern from radial (requiring multiple sources) to linear (achieved through the light guide member), the system achieves 360-degree visual recognition with a single light source, reducing power consumption while maintaining illumination intensity.
2Device complexity
If a light source is positioned to emit light in the direction of the flexible pipe, then the structure is simple, but the light use efficiency is low and visibility is poor
Solution Approach 1:
The light guide member serves as a mediator that captures light emitted by the light source in the direction of the flexible pipe and redirects it along the periphery of the microphone case. This intermediary structure transforms the originally wasted light (emitted toward the flexible pipe) into useful illumination around the microphone case, improving light use efficiency without complicating the overall structure.
Solution Approach 2:
The design converts what would be wasted light (emitted in the direction of the flexible pipe where it would not be visible) into beneficial illumination. The light guide member captures this otherwise lost light and redirects it to illuminate the periphery of the microphone case, turning a harmful loss into a useful function while maintaining structural simplicity.
3Use of energy by moving object
If a single light source is used, then the power consumption is reduced, but the light cannot be uniformly viewed from all directions
Solution Approach 1:
The light guide member acts as an intermediary that receives light from a single point source and distributes it uniformly along the entire periphery of the microphone case. This intermediate structure ensures that light from a single low-power source is evenly distributed around all directions, achieving uniform visibility without requiring multiple high-power light sources.
