Rotatable Grating Insert Module for Adjustable Laser Lamp Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laser lamps in the related art have a single display effect due to an irreplaceable grating, limiting their decorative versatility.
Innovation Solution
A grating-sheet insert module with a rotatable grating insert and a drive module to adjust the display effect, integrated into a laser lamp design that includes a mounting housing and a projection assembly for creating patterns and beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed grating is used in the laser lamp, then the structure is simple, but the display effect is single and decorative versatility is limited
Solution Approach 1:
The grating insert is made rotatable around the central axis of the mounting hole, transforming the fixed grating into a dynamic component. The drive module enables the grating insert to rotate, allowing different grating patterns to be positioned in the light path, thereby changing the projected patterns and enhancing decorative versatility without requiring multiple separate devices
Solution Approach 2:
The grating insert module serves multiple functions: it acts as a light modulator to create patterns, a decorative element with interchangeable gratings, and a rotatable component for dynamic display effects. This multi-functionality resolves the contradiction by making one component perform various decorative roles rather than requiring separate fixed gratings for each effect
2Adaptability or versatility
If a rotatable grating insert with drive module is added, then the display effect becomes adjustable and decorative versatility is enhanced, but the structure becomes more complex
Solution Approach 1:
The grating system is segmented into multiple interchangeable grating inserts, each with different patterns. The drive module is segmented as a separate rotational actuator. This segmentation allows the decorative function to be enhanced through pattern selection while keeping each individual component relatively simple, resolving the complexity issue through modular design
Solution Approach 2:
The grating insert is nested within the mounting hole, with the drive module positioned in the avoiding groove. The compact nested arrangement minimizes the overall space required and integrates the rotational mechanism efficiently within the lamp structure, reducing the perceived complexity while maintaining adjustability functionality
