Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mounting portion is made small to secure light shielding property, then light shielding is improved, but the shape of the reflected light lens is limited and spherical aberration increases
Solution Approach 1:
The reflected light lens is designed as an aspheric lens with a specific curvature profile that reduces spherical aberration. The aspheric surface allows the lens to focus light more accurately while maintaining a compact mounting portion size, thus resolving the contradiction between light shielding and aberration control.
2Object-affected harmful factors
If the opening is made narrow to improve light shielding, then light shielding is improved, but the mountability of a larger transmission region is degraded
Solution Approach 1:
The aspheric lens design allows for a larger effective aperture while maintaining compact dimensions. The curved surface profile enables the lens to achieve the required optical performance with a smaller mounting portion, thus improving both light shielding and mountability.
3Object-affected harmful factors
If the mounting portion is made small to secure light shielding, then light shielding is improved, but assembly efficiency is decreased
Solution Approach 1:
The aspheric lens provides superior optical performance in a compact form factor, allowing for easier and faster assembly. The lens can be mounted in a single direction with proper orientation, reducing assembly complexity and improving efficiency while maintaining effective light shielding.
