Oscillating Light Generation Unit Lens Orientation
Solution Overview
Problem
Existing leveling apparatuses require high manufacturing accuracy to orient lenses perpendicularly, making rapid and simple orientation challenging and prone to manufacturing tolerances.
Innovation Solution
A holding apparatus with first and second holding elements, capable of rotation, with positioning sockets and adhesive-bonded joints to securely and reliably orient lenses perpendicularly, allowing for easy alignment and compensation of manufacturing tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single holding element with a T-shaped recess is used to arrange both lenses, then the structure is compact, but high manufacturing accuracy is required to orient the lenses perpendicularly
Solution Approach 1:
The single holding element is divided into two separate holding elements (first holding element for first lens, second holding element for second lens). Each holding element has its own recess, eliminating the need for high-precision T-shaped recesses while maintaining perpendicular lens orientation through the connection of the two holding elements.
2Manufacturing precision
If high manufacturing accuracy is required for lens orientation, then lens perpendicularity is achieved, but manufacturing becomes difficult and time-consuming
Solution Approach 1:
By segmenting the holding structure into two independent holding elements, each with simple recesses, the manufacturing complexity is reduced while maintaining lens perpendicularity through the geometric relationship between the two holding elements rather than requiring high-precision single-piece machining.
Solution Approach 2:
The holding elements act as intermediaries that connect the lenses to each other. The perpendicular orientation is achieved through the connection geometry of the two holding elements rather than requiring direct high-precision positioning of both lenses in a single holding element.
3Productivity
If rapid and simple lens orientation is desired, then manufacturing time is reduced, but manufacturing accuracy may be compromised
Solution Approach 1:
The segmented holding element design allows for simpler, faster manufacturing of each individual holding element while the perpendicular orientation is ensured by the geometric relationship between the two elements, not by complex machining of a single element.
Solution Approach 2:
The holding elements are designed with predetermined geometric relationships that ensure perpendicular lens orientation. This preliminary design allows for rapid assembly without requiring high-precision adjustment during manufacturing, as the perpendicularity is built into the structure.
