Laser Projection Tool With Curved Window for Wider Fan Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser projection tools require multiple windows or flat windows that restrict laser projection angles and are prone to dirt ingress, leading to durability issues and increased manufacturing costs.
Innovation Solution
A laser projection tool with a single, continuous, and contiguous window featuring curved sections that extends across multiple sides of the housing, allowing wider fan angles and improved durability by enclosing the laser projection devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple windows or flat windows are used, then laser projection angles are restricted, but manufacturing complexity and cost increase
Solution Approach 1:
The patent merges multiple separate windows into a single continuous window structure that extends across multiple sides of the housing. This unified window design eliminates the need for multiple separate window components while providing unrestricted laser projection angles in all directions, thereby resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The window design transitions from traditional flat two-dimensional windows to a three-dimensional continuous structure that wraps around multiple sides of the housing. This dimensional change allows the window to provide coverage and projection capability across multiple dimensions simultaneously, enabling wider fan angles without increasing complexity
2Ease of manufacture
If flat windows are used, then manufacturing is simpler, but dirt ingress occurs leading to durability issues
Solution Approach 1:
The patent employs curved or rounded transitions in the continuous window structure rather than sharp corners and flat surfaces. This curvature design prevents dirt accumulation and ingress at corner joints while maintaining manufacturing feasibility, thereby improving reliability without significantly complicating the manufacturing process
Solution Approach 2:
By merging multiple separate window components into a single continuous window structure, the patent eliminates the joints and seams where dirt would otherwise accumulate. This unified structure maintains simplicity in manufacturing while dramatically improving dirt ingress prevention and durability
3Adaptability or versatility
If multiple separate windows are used, then assembly is required, but manufacturing and assembly costs increase
Solution Approach 1:
The patent combines multiple window functions into a single integrated window structure that provides comprehensive laser projection coverage. This eliminates the need for multiple separate window components and their associated assembly operations, thereby reducing manufacturing and assembly costs while maintaining full adaptability for laser projection in all directions
