Solution Overview
Problem
Conventional ear pickers face issues with inadequate light utilization, leading to light spots and shadows, which affect observation accuracy and can be harmful due to high brightness, while existing solutions do not effectively address these problems.
Innovation Solution
An endoscope auxiliary device with a light-emitting diode light source, a reflective housing, and optical mesh points on a polymethyl methacrylate probing body that improves light distribution and reduces light spots and shadows, combined with health information and image collecting probes for real-time monitoring and data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source is provided on the ear picker, then illumination is improved, but light utilization is insufficient causing light spots and shadows
Solution Approach 1:
A light guide is introduced as an intermediary component between the light source and the ear canal. The light guide transmits light from the light source to the observation area, improving light utilization efficiency and reducing direct light exposure that causes spots and shadows.
Solution Approach 2:
The patent changes the parameters of light transmission by using a light guide with specific optical properties. This transforms the light delivery mechanism from direct emission to guided transmission, optimizing light distribution and reducing unwanted light effects.
2Illumination intensity
If a light source of high brightness is used, then illumination is improved, but light spots are formed and high brightness may be harmful to the eyes
Solution Approach 1:
The light guide serves as a mediator that diffuses and distributes high brightness light over a larger area, reducing the intensity of direct light exposure to the eye while maintaining sufficient illumination for observation.
Solution Approach 2:
The light guide extends the light delivery in a different spatial dimension (through the structure of the light guide itself), allowing light to be distributed over a longer path and larger area, thereby reducing concentrated brightness and harmful effects.
3Ease of manufacture
If conventional materials (metals, plastics, woods or bamboos) are used for ear picker, then manufacturing is simple, but light cannot irradiate to the ear canal effectively
Solution Approach 1:
The ear picker is constructed as a composite device combining traditional materials (for the handle and structure) with optical materials (the light guide made of transparent or translucent material). This composite structure maintains manufacturing simplicity while enabling effective light transmission to the ear canal.
