Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical detecting devices lack fine dust-proofing, leading to pollution from skin furfur, sweat, grease, and ambient particles, which interferes with optical detection precision.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If no transparent component is added to the optical detecting device, then the device structure remains simple and manufacturing cost is low, but the optical detecting component is easily polluted by skin furfur, sweat, grease, ambient dust and suspension particles, leading to noise in optical detection information and reduced precision
Solution Approach 1:
A transparent component is introduced as an intermediary element between the light through unit and the optical detecting component. This transparent component serves as a protective barrier that prevents dust and particles from reaching the optical detecting component while allowing light to pass through, thus maintaining detection precision without significantly complicating the device structure
Solution Approach 2:
The transparent component functions as a thin film or shell structure that covers the optical detecting component. This thin transparent barrier effectively blocks dust and particles from contaminating the optical detecting component while maintaining optical transparency, resolving the contradiction between protection and structural simplicity
2Object-affected harmful factors
If a transparent component is added to block dust from reaching the optical detecting component, then dust-proofing function is improved, but manufacturing cost increases and assembly yield decreases
Solution Approach 1:
The transparent component serves multiple functions simultaneously: it acts as a dust barrier, maintains optical transparency for light transmission, and can be integrated into the existing device structure. This multi-functionality justifies the addition by providing dust protection while maintaining manufacturing feasibility through design optimization
Solution Approach 2:
The transparent component's optical parameters (transparency, thickness) are optimized to balance dust protection capability with light transmission requirements. By adjusting these parameters, the design achieves effective dust blocking while maintaining compatibility with existing manufacturing processes and assembly procedures

AI summary
An optical detecting device capable of preventing environmental pollution includes a casing, an optical detecting component and a transparent component. The casing includes a light through unit and at least one accommodating structure. The optical detecting component is disposed inside the accommodating structure. The transparent component is disposed inside the accommodating structure and located above the optical detecting component, to partly fill the accommodating structure at least and block between the light through unit and the optical detecting component.
