Light Sensor Holder Adjusting Incident Angle via Axial Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light sensors have limited flexibility in detection angles due to their fixed lens configurations, requiring physical lens replacement for different detection ranges, which can lead to non-functionality if specific lenses are in short supply.
Innovation Solution
A light sensor design featuring a fixer tube, sensor component, and a movably coupled holder that adjusts the incident light angle by changing the distance between the sensor component and a first opening, allowing for adjustable detection ranges without physical lens changes, utilizing a groove-and-tongue fit mechanism and stoppers for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional light sensor uses a fixed lens configuration for a specific detection range, then the detection angle is stable and reliable, but the flexibility to adjust detection angles is limited and requires physical lens replacement
Solution Approach 1:
The patent applies the dynamics principle by making the holder movable along the axial direction of the fixer tube, allowing the sensor component to dynamically adjust its incident light angle. This transforms the fixed lens configuration into an adjustable system where the holder can move to different positions (e.g., first position for first detection angle, second position for second detection angle) without requiring physical lens replacement, thus improving adaptability while maintaining structural simplicity.
2Adaptability or versatility
If multiple lenses with different detection ranges are kept for a conventional light sensor, then the adaptability to different detection angles is improved, but the device complexity and inventory management increase
Solution Approach 1:
The patent applies the universality principle by designing a single light sensor system with a movable holder that can perform multiple detection angle functions. The holder can be positioned at different locations along the axial direction to achieve different incident light angles, allowing one sensor to replace multiple specialized lenses. This eliminates the need to maintain an inventory of different lens types while providing comprehensive detection angle coverage.
3Adaptability or versatility
If the holder moves along the axial direction to adjust the incident light angle, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies the segmentation principle by dividing the detection angle adjustment into discrete positional segments. The holder can be positioned at specific locations (e.g., first position, second position) corresponding to different incident light angles. This segmentation approach allows for standardized manufacturing of the holder with predefined positioning features, reducing the overall manufacturing precision requirements compared to continuous adjustment mechanisms while still providing multiple detection angle options.

AI summary
A light sensor includes a fixer tube, a sensor component, and holder. The sensor component is disposed at a bottom terminal of the fixer tube and fixed to the fixer tube. The sensor component senses incident lights. The holder is movably coupled to the fixer tube. The holder encompasses the sensor component. The holder further includes a first opening. The sensor component faces the first opening for receiving incident lights passing through the first opening. The holder further moves along an axis of the fixer tube for adjusting an incident light angle of the sensor component.
